Caloric intake and chronic diseases -

It is not fair to imply that only people who are overweight need to be concerned about their health. In fact, studies of large numbers of people show that it is best—at least from the standpoint of attaining a long life—to be neither too skinny nor too fat.

The numbers of deaths and disabilities from heart disease, cancer, diabetes, high blood pressure, gallstones, and osteoporosis all increase in people who are much lighter or heavier than average.

Studying the relationships between body weight and development of chronic diseases is particularly difficult. Some of the relationships are ''confounded" by genetic and other factors—for example, thin people may be heavy cigarette smokers, and the smoking may be the true cause of cancer rather than thinness.

People's weight may change in the early stages of a disease, prior to its diagnosis, further complicating the study of the relationship of weight to disease. It has been known for decades that obesity occurs more frequently in some families than in others.

Studies of twins suggest that genetics is an important factor in whether people become obese. Because members of a family share meals as well as other habits, identifying the role genetics plays in the development of obesity and the predisposition to chronic diseases is complex.

In addition to obesity, there is increasing evidence that patterns of fat distribution are inherited. Although there is some concern about the effects of being underweight, most research has concentrated on the health effects of being overweight. This is probably because more people in the United States are overweight than underweight.

Whatever the reason, the rest of the discussion in this chapter focuses on the problems associated with being overweight or obese. As defined in the previous chapter page 70 , overweight refers to an excess amount of weight for a person of a given height, and obese indicates an excess amount of body fat compared to muscle and bone.

Let's look at each disease separately. There is little disagreement that the heavier you are, the greater your risk of having a heart attack. People who are 5 to 15 percent overweight have more than twice the number of deaths from heart attacks as people of average weight. For those who are 25 percent or more overweight, the number of fatal heart attacks is 5 times higher than normal.

The evidence is clear: being overweight is associated with having high blood pressure, and losing excess weight usually lowers blood pressure. What is interesting about this, though, is that the effect seems to be related more to body build than to weight itself.

People with low waist-to-hip ratios have lower blood pressure than do people with waist-to-hip ratios close to or higher than one. Excess body fat, which is usually associated with excess body weight, increases the risk of developing noninsulin-dependent diabetes.

In fact, the chance of becoming diabetic more than doubles for people who are 20 percent overweight. What is worse, the risk keeps doubling for every additional 20 percent weight gain.

For example, if a 5'9" man weight pounds, instead of the optimal pounds, his risk for developing noninsulin-dependent diabetes doubles. If he gains even more weight, up to pounds, his risk is twice as high again.

As in the case with high blood pressure, noninsulin-dependent diabetes is more common in people who carry their excess weight primarily on the abdomen those with high waist-to-hip ratios. Being overweight in the hips and thighs resulting in low waist-to-hip ratio , it seems, does not carry as much of a health penalty as far as diabetes is concerned.

This seems particularly true for women. Losing weight is the most effective therapy for people with noninsulin-dependent diabetes.

Study after study has shown that decreasing body weight improves the body's ability to metabolize glucose, the biochemical hallmark of this disease. The evidence shows clearly that being overweight increases the likelihood of developing gallstones.

This is particularly true as a person's age increases. For example, by age 60, nearly one-third of obese women can expect to develop gallbladder disease. The connection between gallbladder disease and weight stems from the fact that being overweight increases the body's production of cholesterol.

With the body making cholesterol, the liver excretes more. This raises the level of cholesterol in bile, which leads to gallstones. The link between cancer and excess weight is not as strong as with the diseases above, but a link does exist.

Being overweight increases the risk of endometrial cancer, in particular, although cancers of the gallbladder, bile duct, ovary, breast in postmenopausal women , cervix, colon, and prostate are also more common in overweight people. We are a nation that weights too much, and we seem to know it—a Gallup poll found that almost 90 percent of U.

adults believed they weigh too much. As a result, dieting has become a major preoccupation with millions of people in the United States. The same poll found that 31 percent of the women questioned dieted at least once a month, and 16 percent of the women considered themselves perpetual dieters.

Other studies have identified even greater numbers of dieters in the U. One reason why there are so many people on diets is that most dieters regain the weight they lose.

In fact, between 60 and 90 percent of the pounds shed on diets in this country are put back on. To lose these pounds, people go back on diets, and soon a cycle develops—gain, diet, lose, gain, diet, lose, and so on. The effects of the diet cycle are unclear, but there is some evidence suggesting that it is not a healthy activity.

For example, several studies have found that people who gain and lose 10 percent of their weight have a higher risk of developing coronary heart disease than people whose weight remains constant.

Repeated cycles of weight gain and weight loss may increase the risk even further. The body may also adjust to the diet cycle by becoming more efficient at using food energy.

Thus each attempt to lose weight becomes more difficult. So if you weigh too much now, lose the excess weight by a combination of eating less and exercising much more than you do currently, and if you are not overweight, stay that way.

These protein sources also provide additional nutrients, such as calcium, vitamin D, vitamin B12, and fiber. The ability to absorb vitamin B12 can decrease with age and with the use of certain medicines. Older adults should talk with their health care provider about the use of dietary supplements to increase vitamin B12 intake.

Healthy Beverage Choices for Older Adults. Unsweetened fruit juices and low-fat or fat-free milk or fortified soy beverages can also help meet fluid and nutrient needs. Health care providers can remind older patients to enjoy beverages with meals and throughout the day.

If older adults choose to drink alcohol, they should only drink in moderation — 2 drinks or less in a day for men and 1 drink or less in a day for women.

Remember that this population may feel the effects of alcohol more quickly than they did when they were younger, which could increase the risk of falls and other accidents. Supporting Older Adults in Healthy Eating. Similar to other life stages, health professionals, family, and friends can support older adults in achieving a healthy dietary pattern that fits with their budget, preferences, and traditions.

Additional factors to consider when supporting healthy eating for older adults include:. Find Resources to Help Older Adults Eat Healthy.

There are a number of government resources that health professionals can use to support older individuals in accessing and achieving a healthy dietary pattern. Choosing healthy foods and actively using nutrition resources can help people make every bite count, no matter their age.

Supporting Older Adults in Healthy Eating Similar to other life stages, health professionals, family, and friends can support older adults in achieving a healthy dietary pattern that fits with their budget, preferences, and traditions. Additional factors to consider when supporting healthy eating for older adults include: Enjoyment of food — Sharing meals with friends and family can increase food enjoyment and provide a great opportunity to share a lifetime of stories, all while improving dietary patterns.

Ability to chew or swallow foods — Experimenting with different ways of cooking foods from all food groups can help identify textures that are acceptable, appealing, and enjoyable for older adults — especially those who have difficulties chewing or swallowing.

Good dental health is also critical to the ability to chew foods. Food safety — Practicing safe food handling is especially important for this age group.

The risk of foodborne illness increases with age due to a decline in immune system function. Find more information on food safety for older adults and food safety for people with decreased immune system function [PDF — 2.

Adults who eat a healthy diet live longer and have a lower risk of obesity, heart disease, type 2 diabetes, and certain cancers. Healthy eating can help people with chronic diseases manage these conditions and avoid complications. However, when healthy options are not available, people may settle for foods that are higher in calories and lower in nutritional value. People in low-income communities and some racial and ethnic groups often lack access to convenient places that offer affordable, healthier foods.
