Plants are loaded with naturally occurring chemicals that appear to help health. And high, long-term intakes of certain kinds of plant chemicals called flavonoids are associated with a reduced risk for developing dementia, according to a study published online April 22, 2020, by The American Journal of Clinical Nutrition. Researchers evaluated the health information of 2,800 dementia-free people (average age 59) who periodically underwent physical exams, had lab tests, and answered diet questionnaires. After 20 years, people who had reported the highest flavonoid intake were about 40% less likely to develop dementia, compared with people who'd reported the lowest intake. There are many different types of flavonoids; those with the greatest link to lower dementia risk came from tea, apples, pears, blueberries, and strawberries. A high intake was about the same as having 7.5 cups of berries, eight apples or pears, and 19 cups of tea per month. A low intake was about the same as having no berries or tea and less than two apples per month. The study was observational and doesn't prove that high flavonoid intake protected people from developing dementia. But researchers say other evidence suggests flavonoids may ward off brain inflammation and protect brain cells.

Spinal instability can contribute to low back pain, but the "big three" exercises can help.

A strong core can stabilize your spine to help keep your lower back healthy and pain-free. The muscles and ligaments surrounding your spine can weaken with age or from an injury, which can make movements like twisting, stretching, lifting, and bending difficult.

"The lower back often has to compensate for this lack of mobility, which places greater stress and burden on its muscles," says Eric L'Italien, a physical therapist with Harvard-affiliated Spaulding Rehabilitation Center.

It's well established that regular exercise is healthy. But how much exercise do you need to achieve health benefits? Even just a little activity — both at home and at work — may reduce your risk of hospitalization, suggests a long-term observational study published May 6, 2020, in BMC Geriatrics. Researchers analyzed the self-reported workplace and leisure activity of 25,000 men and women ages 40 to 79 over a 20-year period. During the first 10 years of the study, people who were active were 25% less likely to be hospitalized for more than 20 days per year, compared with people who were inactive. In the second 10 years of the study, people who remained active or became active — even just slightly — were 34% less likely to be hospitalized for more than 20 days per year. Also, people who were inactive or became inactive during the study had the highest risk of being hospitalized. The take-home message: Stay as active as you can, whether it's a brisk walk most days of the week or just vigorous housework. Even a little activity protects your health.

Don't wait to get hearing aids if you need them. They can improve your quality of life.

Hearing aids may be a symbol of advancing age, but they also can be your means to a healthier and more vibrant life.

Research continues to show that people with age-related hearing loss who get fitted for hearing aids tend to become more active. Some science has even suggested they have fewer cognitive issues.

Scientists continue to explore the health benefits versus risks of aspirin therapy. One new analysis suggests that taking aspirin may protect against several types of digestive tract cancers. The results were published online April 1, 2020, by Annals of Oncology.

Researchers examined 113 observational studies of cancer in the general population. They found that individuals who took aspirin regularly — at least one or two tablets a week — had significantly lower rates of cancers of the bowel, stomach, gallbladder, esophagus, pancreas, and liver, compared with people who did not take aspirin.

Lifestyle improvements, such as quitting smoking and exercising more, can reduce your risk of a stroke.

A stroke may seem like a sudden, uncontrollable event — a lightning strike out of the blue. But in reality, stroke risk often builds over time, and many strokes are preventable. A study published in the May 2020 issue of Stroke found not only that lifestyle changes can help you head off a potential stroke, but also that you can still reduce your risk even if you don't make these changes until later in life.

"What is novel about our study is that we found that even in middle-aged women, changing lifestyle has a large effect on preventing stroke," says Dr. Goodarz Danaei, senior author of the study and the Bernard Lown Associate Professor of Cardiovascular Health at the Harvard T.H. Chan School of Public Health. "Even in the sixth decade of life, lifestyle changes can still prevent up to a quarter of all strokes." The average age in women for a first stroke is 75.

You may be familiar with the claims featured on packages of old-fashioned oatmeal, which note that "As part of a heart-healthy diet, the soluble fiber in oatmeal can help reduce cholesterol." Guess what? Back in 2008, the FDA also approved the equivalent health claim for barley products.

In fact, barley contains about three times as much fiber per serving as oats. Barley is particularly rich in a type of soluble fiber known as beta glucan, which is recognized for its cholesterol-lowering abilities. Barley is also a good or excellent source of several vitamins and minerals.

You might be eager to leap into your exercise routine and get on with the day — but don't just dive in. Starting a workout with "cold" muscles can lead to injury. It's important to start each workout with a warm-up and end with a cool-down — and that goes for true beginners, seasoned pros, and everyone in between.

Warm-up

Warming up pumps nutrient-rich, oxygenated blood to your muscles as it speeds up your heart rate and breathing. A good warm-up should last five to 10 minutes and work all major muscle groups. For best results, start slowly, then pick up the pace. Many warm-up routines focus on cardio and range-of-motion exercises, such as jumping jacks and lunges. If you prefer, you can do a simpler warm-up by walking in place while gently swinging your arms, or even dancing to a few songs. 

Along with historically high unemployment rates, the COVID-19 pandemic has caused a significant increase in food insecurity for millions of Americans, and this problem disproportionately affects lower-income people and racial and ethnic minorities. Temporary measures have helped a bit to ease the situation, and new proposals could do more.
