What you need to know about diabetes

Diabetes is among the fastest-growing health conditions in the United States. Over 30 million adults have diabetes, with 1.5 million new cases each year. If you include prediabetes, which tends to lead to diabetes if untreated, over 115 million Americans are affected. Fortunately, most cases of diabetes can be treated or prevented through healthy eating, weight control, and regular exercise.

Since November is American Diabetes Month, this seems like a good time to raise awareness about the prevention, treatment, and consequences of this serious medical condition.  If you want to learn more about diabetes, a great place to start is American Diabetes Association. This is also the topic of my Health & Fitness column in the Aiken Standardthis week.

Diabetes mellitus is a metabolic disorder characterized by high blood glucose (sugar) caused by a lack of insulin production or impaired insulin action. The lack of insulin production can be caused by an autoimmune disorder that damages the pancreas. This typically occurs during childhood, as in type 1 or “juvenile” diabetes, but it can occur in adults, a condition called latent autoimmune diabetes of adulthood (LADA). For both types, injected insulin is required to control blood glucose.

More commonly, diabetes is caused by the body’s cells not responding to the insulin that is produced, a condition called insulin resistance. This is called type 2 diabetes and is thought to be caused by some combination of obesity, particularly excess abdominal fat, and physical inactivity.

Diabetes can be diagnosed based on a fasting blood glucose test, taken 8–12 hours after a meal, usually in the morning. Another test is an oral glucose tolerance test in which blood glucose is measured for two hours after drinking a special beverage containing glucose. This measures the body’s response to glucose. The hemoglobin A1C test is a long-term measure of blood glucose control. This is important because the higher the hemoglobin A1C level, the greater the risk of diabetes complications.

For most diabetics, the main treatment goal is to control blood glucose level to prevent serious complications including nerve damage, blindness, infection and amputation, heart attack, and stroke. This is typically accomplished through a combination of diet, exercise, and medications, with varying degrees of success. But “curing” diabetes is rare, so most patients require continued treatment.

Exercise is important for blood glucose control because exercise causes an increase in the uptake of glucose into cells and can improve glucose tolerance and insulin sensitivity. In addition, exercise has the added benefits of promoting weight loss and improving strength and fitness. Both aerobic and strength training are recommended, with a minimum goal of 30 minutes per day, every day.

Meal planning involves selecting healthy foods to help maintain consistent blood glucose levels while meeting energy needs for exercise and other activities. The dietary recommendations for preventing and treating diabetes are almost identical to the general recommendations for good health: Emphasize whole grains, fruits, vegetables, legumes, and low-fat meat and dairy and reduce unhealthy fats, added sugars, and salt. The diet should also promote weight loss and weight maintenance, especially for overweight patients. The glycemic index (GI), a measure of how much a food raises blood glucose, can be helpful in dietary planning, but it is not the only meal planning tool that should be used.

Proper diet, blood glucose testing, medication use, and regular exercise can improve blood glucose control, reduce the risk of other health problems, and improve quality of life in diabetics. In those with prediabetes these efforts can delay the progression to diabetes and may even result in a return to normal blood glucose. In fact, diet and exercise have been shown to be more effective than medications in preventing diabetes. Plus, these lifestyle changes lead to weight loss and improved fitness, benefits that no medication can match.

If exercise is medicine, why didn’t your doctor give you a prescription?

What if I told you that there is a prescription your doctor could give you that would prevent and treat high blood pressure, high cholesterol, and diabetes as well as lowering your risk of heart attack, stroke, and most cancers. It can also decrease depression, improve memory and cognitive function better than any other available treatment, and reduce your risk of developing Alzheimer’s disease. And it can help you maintain a healthy body weight, increase your strength, and help you live longer. You would insist your doctor prescribe this for you, right?

The good news is that this prescription exists. The bad news is your doctor may not tell you much about it. This is because it isn’t a drug or other medical treatment—it’s exercise!

The not-so-sweet truth about sugar and your health.

You are probably aware that eating too much sugar is bad for your health. Excessive sugar intake causes hormonal changes and inflammation that can lead to obesity, diabetes, heart disease, and cancer. For decades an emphasis was placed on lowering fat intake, especially saturated fat and cholesterol, to reduce the risk of obesity and heart disease.

Unfortunately, much of this advice was misguided and while fat intake went down, sugar consumption in processed and prepared food increased. This is now seen as a primary cause of the current obesity and diabetes epidemic. The impact of sugar on health and steps you can take to reduce sugar intake are the topic of my Health & Fitness column in the Aiken Standard this week.

Tomorrow is Healthy Lunch Day. Here’s why it matters and why you should do it every day.

Tomorrow is National Healthy Lunch Day, an event promoted by the American Diabetes Association to raise awareness about the need to make healthy choices at lunchtime. We all know that eating breakfast is an important way to start the day. What we may not appreciate is the role a good lunch plays in promoting good health, from helping with weight control to managing diabetes. A healthy lunch can also affect your focus and attention, helping your performance at work or school.


lunch

A healthy lunch is important for treating and preventing many health problems. Diabetes is a perfect example. Perhaps the most important aspect of managing diabetes is to control blood glucose levels throughout the day. Obviously, eating a meal will raise blood glucose. But eating a meal that is relatively low in carbohydrates, especially sugar [https://drbrianparr.wordpress.com/2016/02/29/sugar-and-your-health/], can provide energy without contributing to a spike in blood glucose. The glycemic index (GI) is a useful tool for selecting foods that have a lower impact on blood glucose. Keep in mind that the amount of carbohydrates you eat is important, too, so focusing only on GI isn’t enough. This is especially important for diabetics who take medications, including insulin, to help manage their diabetes.

The idea that eating lunch promotes weight loss sounds counterintuitive, but it works! Skipping a meal can lead to stronger feelings of hunger later in the day. And if you are hungrier you will likely eat more. So, an appropriate midday meal can help you eat less later in the day. Combined with regular exercise, eating appropriate meals and snacks is an essential aspect of weight loss and weight control.

Eating lunch provides energy and reduces hunger at a time when your breakfast is likely “wearing off.” This may help you feel more energetic and can enhance your attention, focus, and productivity. Of course, what you eat for lunch is as important as when you eat. Lots of sugar can make you feel sluggish, both physically and mentally. Unfortunately, added sugar is a big part of many restaurant meals and convenience foods, so the afternoon slump is a reality for many of us. Limiting sugar in both food and drinks can help you make healthier choices at lunch that can make you feel and work better in the afternoon.

“That afternoon slump you feel may be due to what you ate for lunch.”

A good lunch is especially important for children. In addition to providing energy to support growth and learning, lunch also presents an opportunity to teach children about healthy eating. This is critical since formal nutrition education isn’t part of the curriculum at most schools. Sadly, most school lunch programs provide meals that include too much added sugar and refined carbohydrates, inappropriate for growing and learning kids.

Many adults don’t fare much better with their lunch. For a lot of people, the two key criteria for lunch are that it is quick and convenient. And as we know, quick and convenient foods are rarely considered healthy, so this requires some effort to plan ahead and make careful choices.

What makes a healthy lunch? Pretty much the same recommendations for other meals also apply for lunch: low in added sugar and refined carbohydrates and high in fiber. Your lunch should include vegetables, fruit, whole grains, and protein, all of which are foods that can make you feel full longer. In the end, the effort and planning pay off by making you a healthier you!

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.

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.

Raise money to cure diabetes while simultaneously developing your own case of diabetes!

I should’t be surprised to see this. But I still am.

How low should you go?

When it comes to your health, making even small changes can lead to big improvements. Whether you are trying to eat a healthier diet, get in shape, or lose weight, a little effort can go a long way. But doing more can produce even more meaningful changes.

The same is true for risk factors including blood pressure, cholesterol, and glucose. For example, if you have high blood pressure, you can reduce your risk of having a heart attack or stroke by lowering it, even if it doesn’t get into the “normal” range. This is often a goal for patients with high cholesterol or diabetes, too.

According to recent news reports, a major study suggests that treating risk factors—specifically, hypertension—to bring them well below previous targets has even greater benefits. This study, and how it applies to other health indicators, is the topic of my Health & Fitness column in the Aiken Standard this week.

blood pressure


The study, which examined the effect of lowering blood pressure on heart attack and stroke risk, produced such remarkable findings that the results will be published two years ahead of schedule. The researchers found that lowering systolic blood pressure (the top number) to less than 120 mmHg resulted in a risk of heart attack or stroke that was significantly lower than that of treating blood pressure to a typical goal of below 140 mmHg.

This suggests that getting your blood pressure out of the “high” category isn’t enough and that lowering it more is beneficial. Not only is this is good news for people with hypertension, but it also likely applies to other conditions as well. For example, the goal for people with type 2 diabetes is to get blood glucose level, frequently determined by the “A1c” number, as low as possible to prevent complications like blindness, kidney failure, and amputations. And it seems that the risk of heart problems are reduced proportionally to how low LDL cholesterol gets.

This concept can also be applied to health behaviors. For people who are mostly sedentary, something as simple as a 30 minute walk each day can lead to big improvements in fitness. And simply swapping high-calorie drinks like soda or sweet tea for water or other calorie-free beverages can result in noticeable weight loss for many people. And overweight individuals can reduce their risk of diabetes by losing as little as 10% of their excess weight.

But greater changes to activity level or diet almost always have even bigger benefits. Cutting back on calories from drinks is a good start, but losing significant weight almost always requires making other changes in what you eat and how active you are. Walking is an excellent exercise, but greater improvements can be achieved by doing more, either longer duration or a higher intensity. And building muscle will require doing some form of resistance training—walking typically isn’t enough.

It’s true that every pound of weight loss matters, and many people notice changes in how they feel or how their clothes fit after losing as few as 10 pounds. But real transformations in appearance or health require more significant weight loss, especially for people with greater obesity.

Although the SPRINT study focused on only one factor, blood pressure, we shouldn’t limit ourselves to making only one change when it comes to our health. Indeed, the benefits of increasing activity, losing weight, and eating healthier together far exceed doing only one. And, while even small changes make a difference, doing more will almost always result in bigger benefits.
