Fruits and Vegetables for Endurance

A new study found that short-term high protein diets may hinder muscle endurance and short-term high carbohydrate diets may increase endurance. This study found that what elite long-distance runners ate determined which types of bacteria lived in their colons. A diet high in fruits and vegetables (high-carbohydrates) was associated with improved time-trial runs in highly trained competitive runners by 6.5 percent.

Weekend Warriors Gain Full Benefit From Their Exercise

A recent study found no significant difference in death rates between adults who exercised once or twice a week versus three or more times a week, as long as they exercised moderately for a total of 150 minutes or vigorously for 75 minutes per week. This study followed 350,978 U.S. adults for more than 10 years. The participants reported their activity levels and were divided into an active group and an inactive group.

Monkeypox Declared a Public Health Emergency

The U.S. Department of Health and Human Services has declared monkeypox to be a public health emergency, and the U.S. has recorded more than 7000 infections, more than any other country in the world. The only two states that have not yet reported monkeypox infections are Montana and Wyoming.

Leonard Nimoy and COPD

Leonard Nimoy won three Emmy awards for starring in "Star Trek" ((1966-1969) as Spock, a 23rd-century space voyager from the planet Vulcan. He was known for his pointed ears and constant use of the word "fascinating." Nimoy was also an actor in many other film and TV roles, a director of films, a mediocre singer, a published poet and an accomplished photographer.  He gave up smoking two packs of cigarettes a day more than 30 years before his death from COPD (Chronic Obstructive Pulmonary Disease).

Gut Bacteria Associated with Colon Cancer

A study from Harvard Medical School found that a typical Western diet increases growth of specific bacteria in the gut called “polyketide synthase (pks+) E. Coli” that produce a chemical called colibactin, which causes DNA mutations that can turn normal colon cells into cancer cells.

Long COVID Syndrome

The U.S. Center for Disease Control (CDC) reports that 13.3 percent of patients who develop COVID-19 will suffer from Long COVID syndrome, which can last for two months or more and cannot be explained by a different diagnosis. More than 30 percent of hospitalized patients still have symptoms at six months.

Bill Russell, the Ultimate Team Player

Bill Russell, ranked by many as the greatest basketball player of all time, died in his sleep at age 88 on July 31, 2022. No cause of death was given, but a clue may come from his heart valve surgery more than ten years ago. When Russell played on a team, the team almost always won.

Mediterranean Diets are Safer than Keto Diets for Controlling Blood Sugar

A 36-week study from Stanford University compared the benefits of two diets -- a Mediterranean diet and a ketogenic diet -- for treating 33 individuals with prediabetes or type 2 diabetes. Both diets were based on eating lots of non-starchy foods that do not cause a high rise in blood sugar, and avoiding foods that cause a high rise in blood sugar such as sugar-added foods or drinks and foods made from flour (ground-up whole grains).

You Need Both a Healthful Diet and a Regular Exercise Program

A study of 360,600 British adults found that high levels of exercise will not protect you from the life-shortening effects of an unhealthful diet. People who ate an unhealthful diet and exercised vigorously every day still were at increased risk for dying from heart disease, cancer, or any cause.
