A modest uptick in the amount of fruit and vegetables you eat can help ward off type 2 diabetes, according to a study published online July 8, 2020, by The BMJ. From a much larger study involving some 340,000 people from eight European countries, scientists selected 9,754 participants who were newly diagnosed with diabetes over a decade. Researchers compared the fruit and vegetable intakes of these people to those of about 13,000 participants who remained diabetes-free during the study period. Researchers also measured blood levels of seven key plant-derived nutrients, including vitamin C and brightly colored antioxidant pigments called carotenoids. People with the highest intakes of fruit and vegetables and the highest blood levels of the plant-derived nutrients were 25% to 50% less likely to get diabetes during the study period, compared with those who ate the least of these food groups or had the lowest nutrient levels. Even better, it didn't take a whole lot of extra green, red, yellow, and orange on the plate to make a dent in diabetes risk. The equivalent of only two-thirds of a medium apple or just over one-third of a cup of mixed fruit each day offered protection.

Not only can regular leg stretching help reduce cramps and muscle strains, it also may be another way to protect against heart disease and stroke. A study published online July 1, 2020, by The Journal of Physiology found that performing simple leg stretches can help improve blood flow throughout the body.

Researchers split 39 healthy people into two groups. One group didn't do any stretching. The other group performed four types of leg stretches five times a week for 12 weeks. The stretches focused on the hip, knee, and ankle. Each stretch was done for 45 seconds with a 15-second recovery. Afterward, the researchers found that the arteries in the lower legs of the stretching group had better blood flow and less stiffness. The stretching group also had lower blood pressure at the end of the study compared with their initial readings.

Millions of Americans get coughs and colds during the winter, and many head to the drugstore to pick up one of the hundreds of common medicines available without a prescription. But those products often contain multiple active ingredients that are potentially unsafe if combined. Here’s how to safely choose the right over-the-counter medication for your symptoms.

Getting a flu shot is important every year, but this winter there is added urgency due to the COVID-19 pandemic: with both diseases circulating, hospitals may face shortages of beds and equipment –– and it’s possible to have both the flu and COVID-19 at the same time.

Erectile dysfunction (ED) medications are relatively safe and work for most men, but they aren’t right for every man. Here are six proven strategies that can help –– and offer added benefits on overall health and quality of life.

Home delivery is just a few clicks away.

Lots of things can keep you from picking up a prescription at your local pharmacy. You may be stuck at home because of disability, illness, social distancing, or a lack of transportation. But the longer you go without your medication, the more your health is at risk. That's why it's important to know how to use home delivery services that bring prescriptions right to your door.

Local pharmacy delivery

Just like in the old days, some local pharmacies still send their own staffers to deliver prescriptions to their customers. The pharmacies are usually small and independently owned. You might expect that kind of service from them.

Eating a diet high in foods tied to inflammation — such as processed meat, sweets, and refined grains — is associated with many health problems, including an increased risk for colon cancer, heart disease, stroke, or diabetes. A Harvard study published online May 7, 2020, by Gastroenterology found another potential risk: Crohn's disease, a condition characterized by areas of inflammation throughout the large and small intestines. Researchers evaluated 30 years' worth of self-reported diet information from more than 208,000 men and women. Diets were scored based on foods that promote inflammation. Compared with people who had the lowest inflammatory diet scores, people with the highest scores had a 51% higher risk for developing Crohn's disease. The risk for Crohn's doubled among people who went from a low- to a high-inflammatory diet during the study. The study is observational and doesn't prove that an inflammatory diet causes Crohn's disease. But with so many other risks associated with foods that promote inflammation, it's important to eat as many foods that fight inflammation as possible. In other words, focus on whole, unprocessed foods with no added sugar — such as vegetables, fruits, whole grains, legumes (beans, lentils), fish, poultry, nuts, seeds, a little bit of low-fat dairy, and olive oil.

Here's a finding worth toasting if you're partial to a tipple: a study published online June 29, 2020, by JAMA Network Open linked low-to-moderate alcohol drinking in middle age with better cognitive (thinking) skills in older age. Researchers analyzed the health data of about 20,000 adults (average age 61) who took part in cognitive screenings every few years during a nine-year period and reported how much alcohol they drank each week. Men who had fewer than 15 drinks per week, and women who had fewer than eight drinks per week, were considered moderate drinkers. And they're the ones who appeared to have better word recall and vocabulary over time, and slower rates of cognitive decline, compared with people who never drank. The study is observational and doesn't prove that drinking alcohol protects the brain. In fact, the subject is debated: some studies have suggested that moderate alcohol drinking is associated with better cardiovascular health compared with heavy alcohol intake, but other studies have found that drinking any amount of alcohol increases the risk for high blood pressure and stroke. The takeaway: if you're going to raise a glass, do so only in moderation.

In many places, gyms are opening after shutting down due to the COVID pandemic, but your home may still be the ideal place to maintain your fitness.

As gyms and fitness centers reopen, they must follow strict guidelines for sanitation, social distancing, occupancy, and more. Even if these facilities are considered safe by most standards, their patrons still may not feel comfortable, especially older adults and others who are at a higher risk for COVID.

So how do you maintain your fitness when you can't follow your usual exercise routine?
