Honesty is the best policy when it comes to your health

Have you ever justified your weight by saying you are “big-boned”? What about your eating and exercise habits? How often do you really eat out? How many days did you actually get to the gym last month? Are you being honest with yourself when it comes to your health? And are you asking others to be honest with you?

Being honest about your health is the topic of my Health & Fitness column in the Aiken Standard this week.


Being honest with yourself is essential for initiating health behavior changes and setting good goals. For example, someone who tells themselves they need to lose “a few pounds” may really need to lose much more and may not take their weight loss as seriously as they should. Convincing yourself that you are doing more exercise than you really are may mean that you won’t see the fitness or weight loss results you were expecting.

This type of self-deception is easy to do. Take body weight for example. The current standard for determining if you are at a healthy weight is body mass index (BMI), calculated from your weight and height (kg/m2). It requires a bit of math, so using a mobile app or online calculator is a good idea.

A BMI between 18.5 and 24.9 is considered normal, 25-29.9 is overweight, and if your BMI is 30 or higher, you are classified as obese. To put this in perspective, a BMI of 30 is equivalent to about 25–30 pounds of excess fat.

Let’s say your BMI puts you in the obese category, suggesting you should lose weight. But then you think about an article you read about how BMI isn’t accurate because you can be considered obese if you have excess muscle, not fat. And then there was the story on the news suggesting that it is okay to be obese as long as you are physically fit. So, maybe you don’t need to worry about your weight!

See how easy it is to tell yourself that you don’t really need to lose weight? In reality, BMI is an accurate method of assessing your body fatness; the inaccuracies reported in the news almost always involve athletes or people with lots of muscle mass developed through physical labor. Be honest…is that really you? It’s also true that people who are fit and fat can be healthier than people who are thin and sedentary, but it requires a lot of exercise to reach that level of fitness. Again, are you really that fit?

Probably the best test is to take a good look in the mirror and be honest about what you see. Try to “pinch an inch” of fat around your belly. One inch isn’t necessarily a problem, but take notice if you can pinch a handful of fat. Measuring your waist circumference (or looking at your pants size) can give you the same information. People who have a high BMI because of extra muscle, like athletes, have thin waists. If your waist circumference is greater than 35 inches ( women) or 40 inches (men), you have excess fat.

This honesty also applies to others, including your doctor. Many physicians are reluctant to discuss weight and weight loss with their patients, and many patients don’t want to hear what they interpret as a personal attack. Don’t be one of those patients! Ask your doctor for an honest assessment about your weight and the impact it might have on your health.

This is a real problem. According to one report, only 39 percent of obese people surveyed had ever been told by a health care provider that they were obese.     To help combat this problem, the American Medical Association has developed resources to help physicians better communicate with patients about their weight.

Making changes to diet and activity habits is a difficult process, to be sure. Telling yourself that you don’t need to make them only delays getting started and can lead to poor health in the meantime. When it comes to your health, honesty is the best policy!

How to survive an alien invasion. And other more likely threats to your health.

The film Independence Day: Resurgence, the sequel to the 1996 film, opened in theaters last week. The movie is about an alien attack that threatens to destroy the earth. The film has all the makings of a summer blockbuster and will certainly have people talking about alien invaders. It may even prompt some to prepare for an alien attack. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Alien invasion


All evidence suggests that an alien invasion is highly unlikely. Just in case, though, the Centers for Disease Control and Prevention (CDC) Office of Public Health Preparedness and Response has provided advice for surviving a host of disasters that are common in Hollywood blockbusters, including an alien attack. The intention is that preparing for epic disasters also means that you will be prepared for more realistic natural and man-made catastrophes.

I would like to share some health and fitness-related steps you can take to help you survive an alien invasion as well as other more likely threats to your health. After all, you are far more likely to suffer a heart attack than an alien attack, but it makes sense to prepare for both.

The first thing that is clear is that you need to be physically fit to escape or fight alien invaders. Roads and other transportation infrastructure tends to get destroyed in an extraterrestrial strike, so you may have to travel on foot and carry a heavy load of supplies, likely over long distances.

Building speed and endurance through prolonged aerobic exercise and high-intensity interval training can give you an advantage. Developing muscular strength through resistance training would certainly help, too. A comprehensive fitness program at a gym or at home can help you achieve these goals. Even going for a brisk walk everyday will help.

What you eat now can also help you prepare for the aftermath of an alien assault. Both running away from alien attackers and walking for days to a safer place requires that you have adequate stores of carbohydrate and fat. A high carbohydrate diet will increase your storage of muscle and liver glycogen, the primary fuels used for intense exercise so you will have more energy available to sprint and run.

Don’t overeat, though. Maintaining a healthy body weight is beneficial, too. The heavier you are, the more weight you have to carry in your escape, which is likely to slow you down.

Even though the possibility of an extraterrestrial apocalypse is remote, preparing now makes sense. Just as the CDC recommends that you be prepared for aliens in an effort to make sure you are ready for other more likely disaster scenarios, getting in shape to fight or flee attacking aliens also increases your chances of surviving more probable health threats.

Regular aerobic and strength exercise, maintaining a healthy body weight, and eating a healthy diet are the best ways by which you can reduce your risk of a host of health problems. The benefits of these healthy habits include a lower risk of heart disease, stroke, and some cancers along with prevention and treatment of high blood pressure, high cholesterol, and diabetes. These are exactly the type of risks you should be preparing for.

So, as you watch Independence Day: Resurgence think about what you can be doing now to prepare for both an alien invasion and more realistic threats to your health. Visit the CDC website to learn how to prepare for Hollywood-sized disaster scenarios as well as credible information about exercise, nutrition, and health. Then, get started on getting yourself in shape—the aliens will probably attack without warning!

Supermarket Prepared Meals: What to Watch Out For – Consumer Reports

You know that many pre-packaged and restaurant meals are unhealthy and that you should cook at home. But what if you don’t have the time or inclination to cook dinner? Many people turn to the ready-to-eat meals and dishes at their local supermarket.

These foods are convenient, tasty, and look like they were prepared in the store using high quality, fresh ingredients. A healthy alternative to cooking at home or eating out, right? According to a recent report by Consumer Reports, maybe not.

This highlights the challenges we face when trying to make smart food choices, something I have written about before.

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.

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.

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.

The truth about restaurant salads

If you are looking for a healthy option for lunch or dinner at a restaurant, especially if you are trying to lose weight, chances are you will consider a salad. It turns out that at most fast-food and casual dining restaurants, salads may not be the low-calorie or low-fat choice you were expecting. However, ordering a salad can still be a healthy option, as I explain in my Health & Fitness column in the Aiken Standard this week.

Big salad


We think of salads as being a healthy choice because they contain lots of vegetables which are low in calories and high in vitamins, minerals, and fiber. But most restaurant salads are more than just vegetables. At a minimum, you would add salad dressing and many salads also include nuts, fruit, chicken, bacon, or cheese, all of which add fat and calories.

Salad dressing alone can add hundreds of calories. Creamy dressings like ranch and blue cheese tend to be higher in both calories and fat than vinaigrettes. In many cases the salad has more calories than the sandwich or entree you would have ordered instead.

As an example, consider the Premium Bacon Ranch Salad with Crispy Chicken at McDonald’s. This popular salad contains 490 calories and 29 grams of fat. Compared to a Big Mac, which has 540 calories and 29 grams of fat, this salad doesn’t seem like such a healthy option. You could improve the salad by switching from fried chicken to grilled chicken and save 180 calories and 15 grams of fat.

The real problem is the ranch dressing—one packet contains 200 calories and 17 grams of fat. You could skip the dressing altogether, but a more reasonable approach is to switch to the Low-Fat Balsamic Vinaigrette, with only 35 calories and 1.5 grams of fat. Want to really cut calories? The salad with the vinaigrette dressing and no chicken has only 230 calories, almost 300 fewer than the version with crispy chicken with ranch dressing or the Big Mac!

Despite the fact that many restaurant salads have calorie and fat content similar to burgers and other entrees, it doesn’t make them a bad choice. The salad does contain several cups of vegetables, which means it is higher in vitamins, minerals, and fiber than a burger. The salads at McDonalds have about twice as much fiber as most sandwiches.

Think of it this way: the salad may be equivalent to a burger as far as fat and calories go, but it comes with a serving (or more) of vegetables. And the salad is even healthier when you consider that the sandwich would undoubtedly come with fries! One more point: I use McDonald’s as an example here, but the same holds true for salads at other fast food and casual dining chain restaurants.

What if you are at a restaurant and want to order a salad? What can you do to make it healthier? You could order a side salad. Given the huge portions at most restaurants, this smaller serving might be enough. You can also limit the toppings, especially meat and cheese, and choose a lower-calorie dressing. Another tried and true option is to ask for the dressing on the side so you can add just as much as you want. And don’t forget, you can always share one of the large salads with a friend or save half for another meal.

The bottom line is that salads at restaurants can be as high in calories and fat as other “unhealthy” menu items, but they do provide a serving of vegetables you might otherwise miss. And by making a few choices, you can create a salad that is a healthy, low-calorie option.

Forget about low-carb, go smart carb.

Nutrition advice tends to be complicated and contradictory, making simple answers to the question, “What should I eat?” anything but simple (but you still need to do it!). This is particularly true when it comes to carbohydrates. On one hand, current recommendations call for carbohydrates to be the major part of your diet. On the other hand, low-carbohydrate diets are at odds with these recommendations but are still very popular.

For example, the Atkins diet restricts all carbohydrates, including refined grains and sugars. The Paleolithic diet emphasizes minimally processed foods that may have been consumed by our ancient ancestors including lean meat, eggs, fruit, and vegetables while restricting the consumption of grains and added sugars. Both have been shown to promote weight loss better than traditional low-fat diets.

Proponents of low-carbohydrate diets claim that restricting carbohydrates promotes fat loss and eating carbohydrates leads to fat storage and weight gain. It is also likely that people who follow low-carbohydrate diets find them easier to stick to than other diets, so they may actually end up eating fewer calories.

But the problem may not be carbohydrates in general, it might be eating too few of the right carbohydrates. Given that September is Whole Grains Month, this seems like a good time to explore the benefits of going smart-carb instead of low-carb. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Food grains


Sources of carbohydrates include whole grains (such as whole wheat bread), refined grains (white bread), and sugars. Both refined grains and sugars tend to raise blood glucose rapidly, called the glycemic index, which leads to an increase in certain hormones, including insulin. Insulin stimulates the uptake of nutrients into cells, including the storage of fat in adipose tissue. This is one reason why carbohydrates are linked to fat gain and why restricting carbohydrates leads to fat loss.

But carbohydrates from whole grains don’t raise either blood glucose or insulin as much. This “low and slow” response has several benefits, including improved blood glucose regulation, lower triglycerides, and, potentially, reduced fat storage. For these reasons, complex carbohydrates from whole grains are called “good carbs,” in contrast to refined grains and sugars, known as “bad carbs.”

Considering that the typical American diet contains too much carbohydrate from sugars and refined grains and not enough whole grains, restricting carbohydrates may have some benefits. But there is another approach: be smart about your carbohydrate choices. Instead of cutting out all carbohydrates, focus on reducing refined grains and sugars and emphasizing whole grains.

You can meet this goal by limiting your intake of sugars, especially added sugars, and refined grains while increasing your consumption of whole grains, fruits, and vegetables that are high in fiber. When comparing food labels, look for foods that contain whole grains (the first ingredient should be something like “whole wheat flour”) and higher levels of fiber. But be aware that some foods, like many breakfast cereals, contain whole grains but are also high in added sugar. The best advice is to get the majority of your carbohydrates from real food, including vegetables, fruits, whole grains, and legumes, rather than from processed foods.

Something to keep in mind is that although low-carbohydrate diets are associated with weight loss and good health, they are not the only way to achieve these benefits. Indeed, people who are considered to be fit and healthy have a wide range of eating patterns, from vegetarian and low-fat diets to extreme low-carbohydrate diets and everything in between. The one factor they have in common is that they are active. It may be that regular exercise is just as important as what you eat when it comes to promoting health.

It’s not your fault, but it is your responsibility.

Eating well and being physically active are two of the most important things you can do to promote good health. But knowing you should do these things does not always mean it is easy to actually do them.

Despite the simplicity of the message “eat healthy and exercise,” many people struggle with knowing exactly what to do and how to do it. This is largely due to the complicated and ever-changing nature of nutrition and exercise information and the fact that most people receive no education in these areas.

You may even feel like the information you read and hear is designed to confuse you. That may be true, considering that much of the nutrition information we get comes from food companies that are trying to convince us to buy their products. Even scientific research can yield conflicting results, challenging even the most knowledgeable professionals, myself included, to make sense of it. And even if you do decide to make eating or activity changes, the “best” diet or exercise program claims may make you wonder if you made the right choice.

Given this, it’s not your fault if you struggle to understand basic health information and recommendations. But it is your responsibility to learn as much as you can to make the best choices for you and your family.

This is the topic of my Health & Fitness column in the Aiken Standard this week

Man shopping in supermarket

This won’t be easy, of course. The popular media, as well as social media, promote confusion and false promises about nutrition by making claims that some foods are “toxic” while others are “superfoods.” The old good carb, bad carb or good fat, bad fat arguments have been given a new life as eat this, not that lists. The problem is that many of these claims are not supported by science. The research that is done often yields complicated or conflicting results that aren’t explained in a way that actually helps people make good decisions.

The same is true for exercise. No one doubts that exercise and physical activity are essential for good health, but there are conflicting claims about specific benefits of exercise and what the best form of exercise really is. This can lead to the idea that if you aren’t doing the right exercise, it doesn’t count. Nothing could be further from the truth! While there are reasons why some athletes might want specific types of training, the majority of people can benefit from simply spending less time sitting and going for a walk each day.

So, what can you do? Given the confusing and changing nutrition recommendations it’s best to focus on what hasn’t changed. That is, to focus on eating real food rather than processed, prepackaged foods. Planning meals and snacks to include fruits, vegetables, whole grains, nuts, legumes, lean meat, eggs, and dairy should give you plenty of healthy fats, carbohydrates, and proteins.

Instead of worrying about the “perfect” exercise, make it your goal to do something active for at least 30 minutes every day.  Beyond that, dedicating time for aerobic, strength, and flexibility exercise will bring greater benefits. Remember, the best exercise for you is the one you will do! Seek advice from people you trust and credible professionals, but remember that if it sounds too good to be true, it probably is.

Your responsibility isn’t to understand all of the nutrition, exercise, and health information you hear. It’s to make an effort to make a few simple, healthy choices despite that confusing information: Sit less, move more, and eat real food.

How much protein do you need?

Recently I wrote about carbohydrates, fats, and protein, the major sources of energy in our diet. Getting sufficient amounts of these nutrients is essential to promote good health and exercise performance. Given the current trend of low-carbohydrate diets and an emphasis on protein for everything from fitness to weight loss, many people have wondered about how much protein they should eat. This is the topic of my Health & Fitness column in the Aiken Standard this week.


Good food display

As you might expect, protein needs vary from person to person for a variety of reasons. For example, an athlete who is working out to add muscle or training for a triathlon needs more protein than a person who does less strenuous exercise. Despite these individualized protein needs, there are some broad recommendations that apply to most people.

There are two ways to estimate the amount of protein a person needs, both of which you may be familiar with. One is to recommend a certain amount of protein, in grams, based on body weight. The RDA, the amount that meets the needs of almost all healthy adults, is 0.8 grams of protein per kilogram of body weight (g/kg) per day. You can calculate your protein requirement by multiplying your body weight by 0.4, so a 200 lb. person would require about 80 g protein per day. (You can also use an online calculator, like this one)

Meeting this protein requirement isn’t very difficult. A four-ounce serving of meat contains about 30 grams of protein, an egg has 6 grams, and a cup of milk has 8 grams. Plants contain protein, too—whole grain bread and cereal has about 4 grams per serving, and one cup of cooked beans contains about 15 g. Getting enough protein is important, but there is little benefit to eating more protein than you need and excessive intake could cause health problems.

In general, most adults get enough protein but children, women who are pregnant, and older adults should make an extra effort to eat protein-rich foods. Vegetarians and vegans, especially athletes, need to carefully plan meals to get enough protein and the right balance of amino acids to meet health and performance requirements.

The other way to estimate protein needs is based on the number of calories you eat. According to the Institute of Medicine, the acceptable range for protein is between 10–35% of total calories. If you eat 2,000 calories each day, this would equal 50 to 175 grams of protein each day. For someone who weighs 200 lbs, this would be between 0.5 and 2.0 grams of protein per kilogram. Notice that the RDA fits within this range, which accounts for the protein requirements of nearly everyone, including people who have very high protein needs.

While the RDA is sufficient for most healthy people, even those who exercise regularly, it may be too low for athletes engaged in strenuous endurance or strength training. The protein requirement for endurance athletes, including runners, cyclists, and triathletes, is 1.2–1.4 g/kg per day. Athletes who are training to add muscle mass and strength—think football players in the offseason—need even more protein: 1.2–1.7 g/kg per day. This should meet both energy needs to fuel training sessions and provide adequate protein for muscle repair and growth.

For most of us, though, the focus should not be on eating more protein but to get our protein from healthy sources. For starters, several servings of protein-rich lean meat, eggs, and dairy as well as whole grains, legumes, and vegetables should meet protein needs. The emphasis should be on real food rather than processed foods with added protein. After all, no amount of granola bars with added protein will make you healthier!
