Healthy eating for diabetes Archive

Struggling with high blood sugar or diabetes? A study published online March 6, 2020, by PLOS Medicine suggests that increasing your daily fiber intake may help. British researchers combed through dozens of studies with about 10,000 participants who had prediabetes, gestational diabetes, type 1 diabetes, or type 2 diabetes. Compared with people who ate low-fiber diets (19 grams of fiber per day), people who ate another 16 grams of fiber per day (a total of 35 grams per day) weighed less and had lower levels of blood sugar, cholesterol, and inflammation. There were also 14 fewer deaths per 1,000 people among those who ate high-fiber diets. If you'd like to increase your fiber intake, try to eat more fiber-rich foods at each meal. Good sources include whole-grain cereals, legumes, and nuts. For example, a cup of bran cereal has up to 47 grams of fiber, depending on the brand; half a cup of white beans has about 10 grams of fiber; and an ounce of almonds has about 13 grams of fiber. Increase fiber intake slowly, to give your digestive tract time to adjust, and remember to increase your water intake as well.

For people with inflammatory bowel disease (IBD), knowing which foods to eat and which to avoid is important information. An international organization has developed guidelines for some kinds of food, with the aim of helping people with this condition reduce symptoms and inflammation.

Sipping a cup of tea at least every other day or so may be good for your heart, according to a study published online January 9 by the European Journal of Preventive Cardiology.

The study included data from more than 100,000 Chinese adults who were part of a long-term health study. The participants provided health and behavioral information, including how much tea they drank. The follow-up lasted an average of seven years.

Here's what the numbers mean — and strategies to lower your cholesterol if it's too high.

For some women who've had normal cholesterol readings all their lives, that changes at menopause. "Going through menopause often results in lipid and cholesterol changes for the worse," says Dr. Samia Mora, an associate professor of medicine at Harvard Medical School and a specialist in cardiovascular medicine the Brigham and Women's Hospital. Drops in the female hormone, estrogen, are associated with a rise in total cholesterol levels due to higher amounts of low-density lipoprotein (LDL), the "bad" cholesterol, and another blood lipid (fat) known as triglyceride. Over time this can raise heart risks, which is a reason for concern, as cardiovascular disease is the No. 1 cause of death in postmenopausal women, says Dr. Mora.

"So, it's especially important to track the numbers in perimenopause and the early years after menopause, as LDL cholesterol and total cholesterol tend to increase," she says.

Q. You recommend eating fish twice a week. However, I've read that fish contain toxins and microplastics. Is it really safe to eat fish?

A. Most options in life contain both benefits and risks. Foods are no exception. Eating fish has potential benefits (largely from the omega-3 fats they contain) and risks (from the toxins). Do the benefits exceed the risks? That question has been addressed by research — much of it by colleagues here at Harvard. The answers are different for different people, and for different types of fish.

People may let healthy eating and exercise habits slide after starting prescription heart medications, according to a study in the February 18 Journal of the American Heart Association.

The study involved more than 40,000 Finnish people whose average age was 52. From 2000 to 2013, researchers surveyed them at least twice every four years about their body mass index and their exercise, smoking, and drinking habits. They used pharmacy records to track if the participants began taking blood pressure drugs or statins.

If a woman has gestational diabetes during her pregnancy, she has a higher risk of developing diabetes later. But a study published February 10 in Diabetes Care found that breastfeeding may help reduce that risk.

The study, which used data from the Nurses' Health Study II, found that the longer a woman nursed her infant, the lower her risk of developing diabetes later in life. The study included more than 4,000 women who had gestational diabetes. Of those women, more than 800 developed diabetes within the next 25 years. Those who breastfed for six to 12 months were 9% less likely to develop diabetes, compared with women who didn't breastfeed at all. Women who breastfed for one to two years had a 15% lower risk of developing diabetes, compared with women who didn't breastfeed. And diabetes risk was 27% lower in women who breastfed for more than two years. This provides another reason that doctors may want to encourage women with gestational diabetes to breastfeed whenever possible.

This caregiver role has mental and physical health challenges.

You're not alone if you've suddenly found yourself raising your grandchildren. In the United States, three million older adults are primary caregivers to kids of all ages. Like any caregiver role, raising kids (especially young children) comes with many challenges, not the least of which is maintaining your health.

Physical challenges

The care of little kids — feeding, bathing, dressing, soothing, entertaining, lifting, carrying, and chasing after them — requires youthful energy and strength. As a grandparent you may be at a disadvantage, and not just because of age. "You may be slower from chronic conditions — like arthritis, heart problems, or diabetes — and from taking the medications needed to treat them," says Dr. Suzanne Salamon, associate chief of gerontology at Harvard-affiliated Beth Israel Deaconess Medical Center.
