Cancer and fat: New findings about the connection

News briefs

Carrying around extra weight is a known risk factor for developing some cancers. But exactly which kinds of cancer are associated with obesity is debated. A study published Feb. 28, 2017, in The BMJ aimed to narrow it down. European researchers combed through about 100 large reviews of observational studies that looked for links between being overweight and getting cancer.

Out of 36 kinds of cancer evaluated, the researchers found strong evidence for a link to obesity for 11—in the colon, rectum, biliary tract (liver and gallbladder), pancreas, breast, endometrium (uterine lining), ovary, kidney, and the gastric cardia (the junction of the esophagus and stomach); a certain type of esophageal cancer (adenocarcinoma); and one type of bone marrow cancer (multiple myeloma). The researchers said there may be links between obesity and other cancers, but so far the evidence is relatively weak.

How to eat healthy away from home if you have diabetes

For people with diabetes, eating out — whether at a restaurant, a social function, or a friend's home — can be a challenge. Portions can be hefty and packed with calories and saturated fat. When you eat out, it may help to follow these simple guidelines:

  • Ask how entrées are prepared, and avoid fried foods or dishes served in heavy sauces or gravies.
  • Choose skinless chicken, fish, or lean meat that's broiled, poached, baked, or grilled.
  • Get the server's advice to help you select healthy, low-fat dishes. Restaurants are used to dealing with special diets.
  • Don't feel obliged to clean your plate. Eat a reasonable portion, and take the remainder home.
  • Choose steamed vegetables and salads to accompany your meals. Request low-calorie dressings and toppings, and if they're not available, ask for all dressings, butter, and sauces to be served on the side so you can use them sparingly.
  • If you take insulin and you know your meal will be delayed, time your injection appropriately. You may need to eat a roll or piece of fruit to tide you over.
  • If you're craving dessert, have some — but split it with someone else.

5 habits that foster weight loss

The hardest part of weight loss is making healthy choices part of your daily routine without constantly feeling as if you’ve deprived yourself of something. We offer five proven strategies to help you shed pounds based on the experiences of people who have lost weight and kept it off.

Get cooking at home

Sharpening your culinary skills (or developing new ones) can improve your diet, nutrition, and social life.

We tend to cook less as we age. Why cook when you can zap something in the microwave, pour something ready-to-eat into a bowl, or speed-dial for takeout? But this quick-eating trend has made many men adopt diets that put them at risk for weight gain, heart disease, and diabetes.

"Many older men have never developed or have lost touch with kitchen skills, and thus have become too dependent on processed and prepared foods," says Dr. David Eisenberg, of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Ask the doctor: Do artificial sweeteners cause insulin resistance?

In preliminary research, sucralose and acesulfame potassium increased insulin levels, although more studies are necessary to determine whether they—or other artificial sweeteners—increase the risk of insulin resistance.

Incontinence may reflect body fat, not just weight

The risk of developing stress incontinence or urge incontinence increases along with BMI and body fat percentage. Stress incontinence is also associated with declines in grip strength.

Spotting whole grains at the grocery store

That's the first step in avoiding unhealthy refined or highly processed grains.

It's important to eat a diet that includes whole grains. But not everyone knows what that means. "Some people aren't sure what a whole grain is. It can be confusing, and you may wind up making the wrong food choices," says registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital.

Whole-grain goodness

Whole grains are seeds or kernels that have three parts: the bran, or outer skin; the germ, or embryo that can turn into a plant; and the endosperm, or food supply for the embryo. All three parts contain important nutrients such as protein, B vitamins, antioxidants, minerals, and unsaturated (good) fats. Many whole grains—such as barley, rye, and wheat—also contain fiber, which helps lower cholesterol, improves digestion, and controls blood sugar. A study in JAMA Internal Medicine linked eating whole grains to a 9% lower overall death rate and a 15% lower death rate from heart disease, as we reported in April 2015.

Rx for longer life: Maintain healthy habits

It appears that the risk of an early death falls with each additional healthy lifestyle behavior that is maintained, even in people who are overweight.

5 habits that foster weight loss

Paying attention to your eating habits and other lifestyle routines can help nudge down the number on the scale.

If you're like many Americans, you're still carrying an extra pound or two that you gained over the holidays. Over the years, that extra weight can really add up—and that added girth is hard on your heart.

Often, the hardest part about losing weight isn't about knowing what to eat. You've heard it a thousand times: eat lots of vegetables, fruits, whole grains, and lean protein. The real challenge is changing your habits to make those healthy choices part of your everyday routine without feeling too deprived.
