How a good night's sleep might help your heart
Research we're watching
Sleep has long been known to help protect you against heart disease, and researchers now think they know at least one reason why. A study published online February 13 by the journal Nature looked at how sleep duration and quality relates to the buildup of damaging plaque in the arteries.
Harvard Medical School researchers found that a lack of good sleep boosts the body's production of inflammatory white blood cells that earlier research has linked to fatty buildup in the arteries. This could help explain why sleep problems can lead to arterial buildup. Poor sleep is linked not only to clogged arteries, but also to a host of chronic health conditions, such as cancer, obesity, and diabetes — all good reasons to make sure you get your z's.
Answers to the top questions about cannabis extract
Sales of cannabidiol-infused products are expected to top $2 billion by 2021. But is CBD right for you?
Cannabidiol (CBD) is touted as a natural wonder that can help treat symptoms of everything from anxiety to arthritis pain. The plant extract comes from two varieties of cannabis — hemp and marijuana — and is available in creams, tinctures, oils, patches, gummy bears, capsules, and more. You can even add CBD to a latte if you walk into a coffee shop in some cities.
But is CBD safe for older adults? There haven't been a lot of large studies of CBD's safety, but more traditional medicines for pain and anxiety are not free of adverse effects, either. "I think CBD is likely safer than many other treatments people use for pain, insomnia, or anxiety," says Dr. Peter Grinspoon, a primary care physician with Harvard-affiliated Massachusetts General Hospital. Other physicians don't think we know enough about the safety profile of CBD to be sure.
Tuberculosis vaccine shows promise in controlling blood sugar
Research we're watching
A long-used vaccine is showing promise in helping to restore near-normal blood sugar levels in people with advanced type 1 diabetes. Researchers from Harvard Medical School injected adults who had type 1 diabetes with two doses of the bacillus Calmette-Guérin (BCG) vaccine, which is traditionally used to prevent tuberculosis.
Participants in the study, all of whom had type 1 diabetes for many years, all showed significant improvements in their average blood sugar levels after the vaccination. The improvements lasted for the next five years. Researchers said that it appears the vaccine affected a metabolic mechanism that increases consumption of glucose by cells.
What’s a healthy breakfast?
It’s more than okay to skip the early-morning breakfast, but no matter what time of day you break your overnight fast, make your first meal a healthy one that won’t cause your blood sugar to spike.
Higher vitamin D levels linked to lower risk for diabetes
News briefs
Vitamin D is an essential vitamin; low levels are associated with poor bone and muscle health and other chronic conditions, such as heart disease and cancer. Now, a study published online April 19, 2018, by PLOS One has tied higher vitamin D levels to a lower diabetes risk. Researchers followed 900 older adults (average age 74) for 12 years, checking their vitamin D and blood sugar levels during clinic visits. Compared with people whose blood levels of vitamin D were below 30 nanograms per milliliter (ng/ml), people with vitamin D levels of 30 ng/ml or more had one-third the risk for developing diabetes, and people whose D levels were 50 ng/ml or more had one-fifth the risk. This study does not prove that taking vitamin D supplements to raise blood levels of vitamin D would reduce the risk of diabetes, although that is possible. The Institute of Medicine maintains that a blood level of 20 ng/ml or higher is sufficient for 97% of the population. Other authorities think that levels higher than 20 ng/ml are better for health. Large studies are under way to help resolve these differences of opinion.

Coffee: More links to health than harm
News briefs

Past studies have suggested that drinking coffee is associated with many health benefits, such as added longevity, lower blood pressure, less weight gain with aging, and a reduced risk of many diseases, including type 2 diabetes, liver disease, cardiovascular disease, several degenerative neurological diseases (like Parkinson's disease), and cancer. Now a massive review of more than 200 large studies, published Nov. 22, 2017, in The BMJ, backs up many of those links. The largest health benefits were associated with drinking three to four cups of coffee per day: drinking more than four cups per day did not bring additional benefits. It's not all good news, however; the study found that women who drank coffee had greater risks for fracture and pregnancy complications. But over all, the researchers say, coffee drinking appears to be safe. They caution that the findings are all based on observational studies, not randomized controlled trials — the gold standard of research.
Deterring heart disease if you have diabetes
Lifestyle changes are vital, but new medications may help.

Two of the most prevalent health problems in this country — type 2 diabetes and heart disease — are closely linked. People with diabetes are more than twice as likely to die from heart disease than those without diabetes. An array of overlapping risk factors (such as being overweight and having high blood pressure and cholesterol levels) probably explains part of this association.
On the plus side, a diet that emphasizes vegetables, fruits, whole grains, lean protein, and healthy fats, coupled with regular moderate exercise (at least 30 minutes daily, most days of the week) can help people dodge the dangers associated with both heart disease and type 2 diabetes. Even so, most people with type 2 diabetes must also take the drug metformin (or other medications) to help reduce their high blood sugar levels, the hallmark of the disease.
