The kindergarten guide to health.

I often get the opportunity to speak about exercise, nutrition, and health. Sometimes the message is tailored to a specific audience. Other times I have the challenge of providing information that would be relevant for everyone, from students in preschool to their parents and grandparents. It turns out that the advice I would give the youngest children applies to everyone. My Health & Fitness column in the Aiken Standard this week includes four tips that are appropriate for all ages.

Eat a rainbow

Of fruits and vegetables, of course. You have probably heard that you should eat five servings of fruits and vegetables each day. In truth, you should get about twice that. Fruits and vegetables contain essential vitamins and minerals and are a good source of fiber. It turns out that dark and brightly-colored fruits and vegetables are rich in these essential nutrients. For example, even though spinach and iceberg lettuce have about the same number of calories, spinach contains significantly higher levels of iron and potassium. Red and orange fruits and vegetables such as cantaloupe are high in beta-carotene, an antioxidant vitamin linked to a lower risk of heart disease and cancer. Eating a variety of colors will make sure you get all of the essential vitamins and minerals and make meals and snacks more interesting.

Play every day

According to the U.S. Physical Activity Guidelines, children should get 60 minutes or more of physical activity each day, with an emphasis on vigorous activity. While this recommendation can be met through sports, there are benefits to unstructured play, especially in younger children. The important thing is that kids have opportunities to be active at school and at home. Like children, adults should be active every day, preferably doing something we enjoy. Since adults don’t spend time running around playgrounds, we get much of our activity through exercise, but the benefits are the same. Regular activity is essential for maintaining a healthy body weight, improving strength and fitness, and preventing disease in adults and children.

Eat breakfast

Children who eat breakfast every day perform better in class and on standardized tests, have fewer absences, and are less likely to be overweight. A good breakfast can improve memory, attention, and alertness in kids and adults. Eating breakfast is also associated with healthier choices for meals and snacks throughout the day. This is important for losing and maintaining weight. In fact, 80% of people who have successfully lost weight and kept it off report eating breakfast every day. Breakfast really is the most important meal of the day!

Don’t spend too much time watching TV

Or playing video games, or in front of the computer. A typical child spends almost as much time each week in front of a screen as they do in school! This is a major contributor to childhood obesity for two reasons. First, what we now call “screen time” is mostly sedentary, replacing opportunities for activity. Second, television viewing exposes kids to advertisements which promote eating foods that are high in sugar, fat, and calories. The American Academy of Pediatrics recommends a maximum of two hours of TV time per day. Kids who limit their screen time also get more sleep and do better in school. By the way, these same problems apply to adults, too. So do the benefits of reducing screen time.

As I write this I am reminded of the essay “All I Really Need to Know I Learned in Kindergarten,” by Robert Fulghum, which recounts simple lessons we learned as children that are relevant at all ages. I think the idea that the simplest lessons apply to everyone holds true for exercise, nutrition, and health information, too.

Sugar and your health

You are probably aware that eating too much fat and sugar is bad for your health. Excessive consumption of both sugar and fat is associated with obesity and other chronic diseases. You are probably also aware that there has been a movement toward reducing the amount of fat in the food we eat. This can be seen in the vast selection of “low-fat” and “fat-free” foods at the grocery store and, likely, your own kitchen. In place of the fat, many of these foods have added sugar in order to maintain a desirable flavor. This also leads to the “Snack Well effect” after the popular low-fat prepackaged foods that were lower in fat but, in some cases, had the same number of calories as the full-fat version.

The majority of processed foods contain some form of sugar or other sweetener. Sugar as most of us know it is called sucrose and typically comes from sugar cane or sugar beets. If you look closely at a food label, though, you may not see sucrose listed. This is because there are a variety of “sugars” used by food manufacturers. For example, high fructose corn syrup (HFCS) is a sugar derived from corn that is sweeter than regular corn syrup. This is worth mentioning because, thanks to corn subsidies, HFCS is cheap for food manufacturers to use.

The effect of added sugar on health is the topic of my Health & Fitness column in the Aiken Standard this week.

Sugar cubes


Many public health medical professionals are increasingly concerned about the high sugar consumption in our population. Despite eating more reduced-fat foods, Americans have been getting fatter, and high sugar intake is thought to play a role in this trend. The individual and public health effects of excessive sugar consumption have been known for years. In addition to the extra calories from sugars that lead to weight gain, the way that sugar is metabolized is associated with hypertension, high blood glucose, and high blood lipids. This combination of conditions is called the metabolic syndrome and is linked to a high risk of diabetes and heart disease.

Obviously, reducing sugar consumption would be beneficial to many. Once controversial suggestion for how to reduce sugar consumption is through taxation and regulation. The idea of taxing added sugar is not new and the idea of a “fat tax” was proposed years ago as a way of limiting the amount of added fat in foods. Although controversial, one potential benefit of taxing products that contain added sugar—soda, other sweetened beverages, and sugared cereal, for example—is that significant revenue could be generated. This money could be used to subsidize the cost of healthier foods or to offset the health care costs associated with obesity.

Even more controversial is a recommendation that children be restricted from purchasing sugar-sweetened foods and beverages, similar to the age requirement to purchase alcohol. This would limit access for children, who stand to experience the greatest health consequences from excessive sugar intake.

It is unlikely that these regulatory measures will be enacted any time soon, if ever. But it does start a conversation about the negative effects our food supply has on us. You should note that the focus is on added sugars in processed foods, not naturally-occurring sugars in fruit and plain milk or the sugar you add to your coffee.  In the meantime, you should make efforts to reduce your consumption of added sugars. One easy way to limit the amount of added sugar you eat is to avoid processed foods and eat more “real” food. You should also pay attention to food labels and look for foods and snacks that have no added sugars.

Your Heart Month action plan

Heart disease, sometimes called coronary artery disease, is the leading cause of death in the United States. Despite improvements in prevention, diagnosis, and treatment, it is still responsible for nearly 600,000 deaths each year, mostly from heart attacks. Millions more are at increased risk because of certain biological and behavioral risk factors. Some of these risk factors cannot be changed, such as age, sex, and family history, while others can be altered to reduce risk. These modifiable risk factors include smoking, high blood pressure, high cholesterol, diabetes, obesity, and physical inactivity. You can learn much more about heart disease from the American Heart Association.

Since February is Heart Month, this is an ideal time to assess your own risk of heart disease and take steps to improve your heart health. If you aren’t sure where to begin, my Health & Fitness column in the Aiken Standard this week includes four simple steps you can take to assess and lower your risk for heart disease. If you aren’t sure where to begin, these four steps should be a good start to prevent and treat heart disease.

Heart

 

 

 

 

 

 

 

 

 


Here is your Heart Month action plan:

  1. Assess your risk. If you haven’t done so recently, you should see your doctor to have your risk factors evaluated. This includes tests for blood glucose and blood lipids (including total, LDL, and HDL cholesterol and triglycerides), measurement of your blood pressure and body weight, and an assessment of other health factors such as your family history, whether you smoke, and your level of physical activity. You may be able to find a health fair or other event in the community at which you can have many of these measurements made, but only your doctor can help you determine the best course of treatment given your personal risk profile.
  1. Be active everyday. The benefits of as little as 30 minutes per day physical activity are well-established and impact heart disease risk in a multitude of ways. Physical activity helps with weight control, lowers blood pressure, improves blood lipids, and prevents and treats diabetes. Think of this as a great health “deal.” By modifying one risk factor—inactivity—you can also promote beneficial changes in four others—obesity, hypertension, high cholesterol, and diabetes. There is no other treatment, drugs included, that can have such a broad impact on reducing heart disease risk!
  1. Improve your diet. If you are like most Americans, your diet is too high in unhealthy fats, salt, and added sugar and lacking adequate whole grains, fruits and vegetables, and fiber. This type of diet is associated with obesity, high blood pressure, high cholesterol, and diabetes. All of these conditions are risk factors for heart disease, so you may literally be eating your way to a heart attack. Changing what you eat to include more whole grains, fruits, vegetables, and low-fat meat and dairy and minimizing added sugars, fat, and processed foods can help you lose weight and prevent or treat high cholesterol, diabetes, and high blood pressure.
  1. Quit smoking. There is no way around this one—quit! Ask your doctor about prescription medications that can make quitting easier. Nicotine replacement therapy in the form of patches, gum, and lozenges can help manage cravings and are available over the counter. Ultimately, though, quitting smoking is a behavior change that takes motivation, willpower, and time. But it is worth it—your risk of heart attack goes down within days and can drop 50–70% within five years after quitting.

The potential impact of these steps is great. Knowing which risk factors are most concerning can help you and your doctor make the most effective treatment decisions. Even modest changes in diet and activity can lead to improvements in risk factors and reduced heart attack risk. The best news is that you can start today by putting down your next cigarette, going for a walk, and eating a healthier dinner. Your heart will be glad you did.

Finally–Three healthy foods that you actually might like!

If you pay attention to news about food and nutrition you will notice that there is a great deal of controversy about what we should eat. Often it is very black and white: Some foods are good for you, while others are bad. In reality, nutrition information almost always falls in the gray area between good and bad. There are very few foods that are always bad for you, but some are certainly more healthful than others.

Eating more vegetables and drinking enough water are two examples of things that everyone should do and are included in nutrition recommendations, almost without exception. Everyone should eat more vegetables and drink more water!

There are some foods, though, that seem to have health benefits, but aren’t necessarily recommended for everyone. You don’t have to consume these foods, but if you do, they may be beneficial. This is usually due to the presence of a nutrient or other component of the food, and the health effect is usually small.

My Health & Fitness column in the Aiken Standard this week provides three examples of foods that have some health benefits.  You don’t have to eat them, but you may want to—in moderation, of course!

Coffee chocolate wine


Chocolate

Chocolate contains phytochemicals, plant-derived compounds that have health benefits. Indeed, chocolate does contain antioxidant flavonoids that have been shown to affect a variety of physiological systems. The beneficial effects include dilation of blood vessels, improved blood clotting, and reduced inflammation, all of which can reduce the risk of cardiovascular diseases including heart attack and stroke. Additionally, these flavonoids may lower blood pressure, regulate insulin levels, and reduce stress. These flavonoids are what give dark chocolate more of a bitter flavor than milk or white chocolate. Look for chocolate that contains at least 70% cocoa (sometimes listed on the label as cacao or cocoa solids) and remember that a small amount is enough.  Since chocolate does contain sugar and calories, eating more may not be the best idea.

Coffee

Coffee also contains many of the same or similar flavonoids as chocolate that have similar effects and benefits. Research shows that moderate coffee consumption (2-3 cups per day) is associated with a lower risk of heart disease. Coffee also contains caffeine which can have additional benefits related to alertness, attention, and exercise performance. If you choose not to consume caffeine, decaffeinated coffee still contains the beneficial phytochemicals. But make sure you are drinking coffee. Many popular coffee drinks are more like milkshakes, with lots of added sugar and calories.

Wine

You have probably heard that red wine is good for you. This is because it has many of the same antioxidant phytochemicals found in chocolate and coffee, wine can be a good source of these nutrients. Indeed, drinking 1-2 glasses of red wine has been shown to reduce the risk of hypertension and heart disease. Obviously, wine contains alcohol so more isn’t better and non-drinkers are not encouraged to start.

The good news is that there are some foods you may enjoy that can actually be good for you. With all of these, more isn’t better, so moderation is the key. Also keep in mind that many fruits contain the same antioxidants as chocolate, so a serving of berries, for example, may be a better choice. And finally, achieving good health requires more than simply changing one aspect of what you eat, so include these foods as part of a diet that includes real food balanced by daily physical activity.

Football in the news: The Super Bowl and CTE

Football has been in the news recently, and not just because of the Super Bowl. In the past few weeks, it has been reported that several former NFL players suffered from brain injury as a result of concussions sustained over years of playing. Some players have even retired early in their careers in an attempt to avoid such injury. Far from being an NFL problem, the issue of sports-related concussion is something that should concern young athletes who play football and other sports, as well as coaches and parents. This is the topic of my Health & Fitness column in the Aiken Standard this week.

 


Football, especially at the professional and college level, has long been known for violent collisions. An obvious concern is that players could sustain a career-ending injury and head injuries, including concussions, are particularly worrisome. In particular, repeated concussions can cause a degenerative brain disease called chronic traumatic encephalopathy, or CTE. The recent motion picture Concussion brought this issue to the attention of a wider audience, but many sports medicine professionals have been aware of this problem for years.
A concussion is caused by the brain moving forcibly inside the skull as the result of the head striking an object (another player or the ground) or simply the head moving violently without hitting anything. Because of this, concussions and sub-concussive injuries can occur even when an athlete doesn’t lose consciousness or appear to be injured. This can put athletes at increased risk for multiple injuries in a season—or even in a single game. This last part is critical, because much of the permanent damage comes from a second concussion sustained before the first has healed completely.
New rules banning helmet-to-helmet contact are part of an effort to reduce the risk of concussions. Off the field, players are subjected to special screening to detect concussions, assess recovery, and determine if it is safe to return to play. Improvements in equipment, including helmet technology that can monitor potentially concussive hits, may also help reduce the risks of serious injury.
Despite these efforts, some experts believe that football is simply too dangerous and have called for tackling to be banned. These concerns are more frequently expressed when it comes to youth football. The evidence that accumulated brain trauma sustained by young athletes can have immediate and lasting effects has lead some communities, schools, and even whole states to consider banning tackling in youth football.
This is complicated by the fact that other sports also have a high risk of concussion, including hockey and soccer. In fact, heading has been banned in some competitive youth soccer leagues. And there is the fact that all sports have some risk of injury, including concussions. Furthermore, youth sports, including football, provide a great many young people with opportunities to be active, promote growth and development, enhance academic achievement, and have fun. The effect of banning tackling in football or heading in soccer on the health, social, and educational opportunities for young athletes is unknown and should be considered.
Whether policies like these are practical or not remains to be seen. In the meantime, there are steps we can take to make all sports safer for young athletes. We should make sure that coaches are educating players how to compete as safely as possible instead of emphasizing winning at all costs. We should also advocate for having certified athletic trainers at all games and practices to teach players safe techniques, assess and treat injuries, and ensure appropriate return to play. Most of all, we should be mindful of the risks of playing sports while encouraging kids of all ages to be active, play, and have fun!

Exercise is an effective, but underused, treatment for depression.

You probably know that exercise is good for your physical health. A lower risk of weight gain, diabetes, heart disease, and some cancers are among a long list of positive health effects of physical activity. Lesser known benefits include improved mental health, cognitive function, and greater feelings of wellbeing. In fact, research shows that exercise is an effective way to prevent and treat depression, which is the topic of my Health & Fitness column in the Aiken Standard this week.

Yoga class


Depression has been in the news recently following the release of new guidelines for the screening for depression in all adults, especially women during and after pregnancy. Considering that depression affects almost 15 million American adults and is a leading cause of disability, diagnosing and treating depression should be a priority. Unfortunately, the effectiveness of common depression treatments, including antidepressant medication, is questionable.

It turns out that exercise is an effective, if underused, strategy to treat depression. Exercise itself has been shown to be as effective as some medications for reducing depression symptoms. More commonly, exercise is used in addition to other treatment strategies, including antidepressant medication, increasing the effectiveness of those therapies. One study showed that exercise can reduce depression symptoms after just 10 days, even before many medications are effective.

It appears that both aerobic and resistance training are beneficial. It is also possible that social support experienced through group exercise is important, too. Additionally, where the exercise is conducted matters and exercise outdoors, especially in nature, can be particularly beneficial.

Indeed, activity outdoors leads to enhanced feelings of energy and diminished fatigue, anxiety, anger, and sadness compared to similar activity conducted indoors. In one study, people who walked in a quiet, tree-lined area had greater improvement in mood—they felt happier—than those who walked along a busy street in an urban area. The researchers also completed brain scans to determine that the difference in mood was related to changes in blood flow in the brain. Additionally, some research suggests that outdoor activity may improve attention in adults and children.

The good news is that almost any indoor exercise can be moved outdoors. While walking, running, and cycling are most obvious, resistance training exercises using body weight and many high-intensity interval training workouts can be modified for outdoors. Yoga and aerobics classes in the park are also great ways to promote both the physical and psychological benefits of exercise.

Much of the psychological benefit of outdoor exercise occurs in the first five minutes, so even short bouts of activity are meaningful. It also means that going for a short walk outside when you have a break at work or walking instead of driving short distances can have positive effects. At home, taking the dog for a walk, playing outside with the kids, or doing yard work are good ways to be active and reap the benefits of being outdoors.

Every little bit of activity you do outdoors will have both physical and psychological benefits to help you become and feel healthier. So, get outside and get active!

Follow the new Dietary Guidelines for Americans? Would if I could.

The most recent update to the Dietary Guidelines for Americans was released earlier this month. This is the latest attempt to provide us with information about what we should eat—and not eat—to stay healthy. The new guidelines, and why they may be difficult for many people to follow, are the topic of my Health & Fitness column in the Aiken Standard this week.

Good food display


Like past updates, there is some debate about the recommendations in the current guidelines. Uncertainly about the role that specific foods and nutrients (saturated fat, for example) play in promoting health and political influence from segments of the food industry are causes for criticism of these guidelines.

Despite the controversy, the guidelines do provide some good advice for us to follow. For example, they recommend that we eat a variety of fruits and vegetables, something that almost everyone agrees is healthy. Refined and processed grains should be limited in favor of whole, unrefined grains. Furthermore, added sugars should be avoided. There is good support for these recommendations, and the distinction is a welcome one. The recommendations for fat are a bit less clear, but the guidelines steer us toward “healthier” fats from plants, including nuts and seeds.

No doubt, everyone could experience some health benefits from eating more fruits and vegetables, favoring whole grains over refined, and limiting the consumption of processed foods containing added sugars. In my mind, the problem isn’t the recommendations themselves (although I might make some changes), it’s the fact that following them is challenging, if not impossible, for many people.

First, access to fresh fruits and vegetables is limited for many people, either by availability or by cost. The well-meaning advice to shop the perimeter of the grocery store avoids many of the unhealthy processed foods that are found in the center aisles of most stores, but it also results in a cart filled with more expensive produce, dairy, and meat. Many people simply can’t afford or shop this way, so the prepackaged, processed foods and meals are practically a necessity.

Second, making smart decisions in the grocery store and in restaurants requires that you have some nutrition knowledge. At the very least, reading food labels is essential. Unfortunately, the “label language” used to make nutrition claims on the front of packages and the less-than-complete information on the Nutrition Facts panel makes this challenging. Claims like “fat free” and “no high-fructose corn syrup” may seem to indicate a healthier choice, when in reality these foods are often no better than the alternatives on the next shelf.

Even though interpreting and following the new Dietary Guidelines for Americans can be challenging, it is still important to try. Making real food, as opposed to processed, prepackaged “food,” your first choice whenever possible will go a long way toward making your diet healthier. This will certainly involve putting more thought into what you eat, and you may find yourself preparing more meals at home rather than eating out.

And try not to worry too much about the debate about which foods and nutrients are the healthiest. If you select food that is as close to its natural state as possible you are likely to make good choices. For example, choose plain beef, poultry, and fish as opposed to flavored, cured meats. The same is true for dairy products like yogurt—watch out for lots of added sugar!

Regardless of what the current and future Dietary Guidelines say, you should strive to follow advice of author Michael Pollan: Eat food, not too much.

When fat attacks! Use your muscle to fight back.

Everyone knows what fat is. It’s where the extra calories you eat end up and the reason your clothes fit too tightly. But beyond that, it doesn’t do much, right? While fat, or adipose tissue, is a place to store excess energy, research shows that it also plays an active role in health and disease. In fact, your fat may be keeping you fat! The good news is that weight loss and regular exercise can reverse the negative health effects of excess body fat. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Adipose tissue


Body fat is essential for storing extra energy, something that allowed our caveman ancestors to survive times when food was scarce. But fat cells have important biological functions beyond storing extra energy. It turns out that fat cells release chemical signals called adipokines that have effects on other organs and tissues.

For example, type 2 diabetes is strongly linked with obesity. Type 2 diabetes is a condition of high blood glucose caused, in large part, by cells not responding to the hormone insulin. Resistin, which is produced by fat cells, has the effect of causing insulin resistance in the liver and muscle, the two major places where excess glucose is stored. The result is high blood glucose, the hallmark characteristic of diabetes.

Fat cells also secrete adipokines such as leptin and TNF-alpha that promote inflammation and abnormal function of blood vessels. This is associated with atherosclerosis, the development of cholesterol-containing plaques that form in blood vessels. These plaques may be unstable and rupture, leading to clot formation that causes a heart attack. This is one reason why obesity is a major risk factor for cardiovascular disease.

The hormone leptin also plays an important role in regulating body fat stores. Leptin signals the brain about the amount of fat stored in the body. When body fat stores decrease, leptin stimulates appetite to increase energy intake and storage as fat; when body fat increases, appetite is reduced.

At least that is the way it is supposed to work. The effect of leptin on appetite is only a suggestion, and it is easy to eat despite it. The result is excess energy intake which leads to obesity. Worse, the brain develops a resistance to the high levels of leptin produced by the excess body fat and establishes a new “normal” level. When someone loses weight and leptin levels go down, the brain responds by increasing appetite. Is it any wonder why losing weight and keeping it off is so difficult?

The good news is that losing weight and body fat, no matter how difficult it can be, can reduce the negative effects of these adipokines. The even better news is that exercise can reverse some of this damage, even if you don’t lose weight. The reason is that, like adipose tissue, muscle produces chemical signals, too.

These myokines also have beneficial effects include improving insulin sensitivity and reducing inflammation. This is one way in which regular muscle activity (exercise) is thought to promote good health. Myokines can also counteract the negative effects of adipokines by creating a balance between the two opposing effects.

In fact, the myokines that are stimulated by exercise can have a greater effect than the adipokines. This helps explain why being obese but physically fit may actually be healthier than being a normal weight but unfit.

The bottom line is that excess fat is unhealthy and we are starting to understand the mechanisms that explain why. Losing weight is important for improving your health. And exercise may be even more important, so you should strive to be more active regardless of your body weight

If you want to learn more about the role of adipose tissue on health, these two articles are a good place to start (fair warning–they are high-sci):

How washing your hands, going for a walk, and getting enough sleep can make this a healthy New Year!

Now that the holiday season is behind us and 2016 is underway we can focus on our goals and resolutions for the new year. Staying healthy is essential for achieving these goals, whatever they may be. Unfortunately, the natural spread of cold and flu viruses at this time of year can interfere with your plans. The good news is, there is much you can do to reduce your risk of getting sick, which I explain in my Health & Fitness column in the Aiken Standard this week.

sneeze


For starters, getting a flu vaccine is the most important thing you can do to prevent seasonal influenza (flu). And it’s not too late if you haven’t gotten your flu shot yet. You can also protect yourself by not touching your eyes, nose, or mouth and by washing your hands frequently with soap and water or using an alcohol-based hand sanitizer. You have probably been doing it wrong, so you may want to learn this song.

Exercise can have a positive effect on your immune system. People who exercise on a daily basis have fewer and less severe colds and have up to 50% fewer sick days than those who aren’t regularly active. Research in animals and humans shows that exercise increases the activity of certain immune cells called helper T cells. This makes the immune system response to viruses, like the cold and flu, more robust. The strongest evidence is seen when the exercise is moderate in intensity and duration, such as a 30–60 minute walk or jog each day.

More exercise isn’t always better, though. Very vigorous and prolonged exercise can have the opposite effect. Athletes who engage in long, intense training tend to be more susceptible to upper respiratory infections. Research shows that immune function is depressed in the weeks leading up to and after running a marathon, resulting in an increased risk of becoming sick. The bottom line is that while exercise improves your immune system, very vigorous exercise may not.

Regular exercise also enhances the immune system response to the influenza vaccine. This means that the flu vaccine can be more effective in people who exercise. If you don’t exercise already, you can still benefit: one study showed that a single 45 minute exercise session can improve the immune response to the flu vaccine. You can get this benefit by going for a brisk walk before your flu shot.

Good nutrition is also important for optimal immune system function. Deficiencies of certain nutrients can have a negative effect on immune function, so eating a balanced diet is essential. That said, there is no support for “boosting” the immune system by taking high doses of vitamins, minerals, or other supplements, despite the claims made by supplement companies. In fact, one supplement company paid $23 million to settle a class action lawsuit regarding false claims that it prevented colds.

You can get benefits from two more common-sense recommendations: getting adequate sleep and reducing stress. Poor sleep habits are associated with suppressed immunity and more frequent illness. Sleep deprivation can also reduce the positive immune response to a vaccine. Another study showed that sleep following a vaccination enhanced the effectiveness of that vaccine. High levels of stress increase susceptibility to colds and the flu and can lead to more sick days from work or school. Stress and poor sleep habits tend to occur together, creating a double negative effect on the immune system.

In order to have your best chance of staying healthy this year you should exercise every day, eat a healthy diet, manage your stress, and get enough sleep in addition to following the traditional advice to get a flu shot, wash your hands frequently, stay away from people who are sick, and stay home yourself if you are ill. As a bonus, many of these habits will also help you lose weight and reduce your risk of diabetes, heart disease, and some cancers along with keeping you healthy this cold and flu season.

It’s not too late! Tips for getting started on your New Year’s resolutions.

It’s time to get started on your New Year’s resolutions! If your goal is to eat healthier, lose weight, start to exercise, or quit smoking, you are not alone. Not only are these some of the most common changes people want to make, these are also among the most challenging behaviors to alter. Progressing from just starting out on January 1 (or today) to successfully changing habits in the long run can be a difficult and lengthy process. My Health & Fitness column in the Aiken Standard this week shares some simple steps you can take right away to get your New Year’s resolutions off to a good start.

2016 time to succeed


Eating Healthier

The typical American diet contains too much processed food which tends to be high in added sugars, fat, and salt and not enough “real food.”

  1. Start with five fruits and vegetables each day—but aim for twice that many. Fresh is best, but frozen vegetables are a good alternative.
  2. Avoid added sugars and salt, especially in prepackaged foods and snacks. This will help steer you toward food that is less processed and healthier overall.
  3. Read food labels. Nutrition information can be confusing, but learning how to interpret food labels can help you make healthier choices.

Starting an Exercise Program

Regular exercise is probably the most important thing you can do for your health. The good news is that a little activity goes a long way.

  1. Dedicate time for exercise each day. At a minimum you should aim for a 30 minute walk, and you can split that up into 10 to 15 minute bouts if you need to.
  2. Start slowly. Building endurance and strength takes time, and doing too much too soon can lead to injury.
  3. Join a gym. You can get all the exercise you need at home, but joining a gym gives you more options for equipment, classes, and personalized advice.

Losing weight

Successful weight loss requires that you change your diet and activity habits. Unfortunately, there are no shortcuts that work in the long term.

  1. Reduce portion sizes. The quickest way to cut back on calories is to limit the amount of food you eat.
  2. Eat healthier food. Fruits, vegetables, and whole grains tend to be low in calories and can help you feel full. Limiting added sugar and fat in foods reduces calories even more.
  3. Exercise every day. Research shows that people who lose weight and keep it off exercise every day for at least an hour. Work up to an hour of walking each day to be a “successful loser,” too.

Quitting smoking

Smoking is a difficult habit to break, owing to the addictive effects of nicotine and the social and behavioral aspects of smoking.

  1. Get rid of all cigarettes (and matches and lighters) now. This means at home, work, and your car. Don’t forget the pack you have hidden away for an “emergency.”
  2. Check out nicotine replacement therapy. Nicotine patches, gum, and lozenges are available over-the-counter at most stores and are recommended for nearly everyone who wants to quit smoking. There are prescription drugs that can help, too.
  3. Change your behavior. Smoking is ultimately a behavior that is influenced by people, places, and situations you encounter. Learning why you smoke is essential to help you quit.

 

Your ultimate goal should be to change these habits and behaviors forever. Doing so will require that you make a series of changes that you can stick with in the long run. It won’t be easy, but the health, fitness, and wellbeing rewards are worth the effort. And focusing on making a few simple changes should get you off to a good start.


Nutrition, exercise, and health information can be confusing. 
But it doesn't have to be that way.
