Men’s Health

Nutrients improve reproductive health and lower the chances of cancer in men-Men’s Health

CoQ10 raised sperm counts

Men's HealthCoenzyme Q10 is an antioxidant present in most cells that also helps produce cellular energy. In this study, 212 infertile men with sperm abnormalities took 300 mg of CoQ10 per day, or a placebo, for six months. Thirty months later, men who had taken CoQ10 had much higher sperm counts and movement, with more normal sperm able to penetrate and fertilize an egg. Doctors believe CoQ10 improves sperm quality by combating oxidative stress in the testes.

Cranberry reduced urinary tract infection improving men’s health

Lower urinary tract infections are common in older men, and doctors in this study wanted to test cranberry in 42 men with inflamed prostate and higher chances of prostate disease. The men took 1,500 mg of dried cranberry powder per day, or a placebo. After six months, while the placebo group had not improved, men’s health in the cranberry group had much improved prostate and urination symptoms, including more normal prostate-specific antigen levels.

Zinc and cancer

Zinc is an important antioxidant that also helps protect DNA and doctors in this study wanted to measure the effect of varying zinc levels on DNA. Nine healthy men who consumed an average of 11 mg of zinc per day went on a 55-day diet to deplete zinc, followed by 27 days replenishing zinc levels. During the zinc-depletion phase, DNA damage in blood cells increased, and reversed when zinc returned to healthy levels. Doctors concluded that zinc helps maintain DNA integrity, which may reduce likelihood of cancer.

Early-Stage Nutrition Discoveries–Metabolism

Lab studies find nutrients increase metabolism, reduce fat, improve blood fat and sugar levels, and ease symptoms of metabolism syndrome

Resveratrol and metabolism

Resveratrol Metabolism SupplementIn a lab study, mice that consumed a diet including an experimental mega-dose of resveratrol ate 13 percent fewer calories and had an increase in resting metabolic rate of 29 percent. Scientists said resveratrol may help in obesity therapies.

Blueberries and diabetes

In a lab study, rats consumed a diet including freeze-dried blueberry powder as 2 percent of total calories. After 90 days, compared to those that didn’t eat blueberries, the blueberry group had less abdominal fat, lower triglycerides and cholesterol, and improved fasting blood sugar levels and insulin sensitivity. The benefits were greater with a low-fat diet, including lower body weight and total fat and liver mass. The liver can enlarge with obesity, insulin resistance, and diabetes. Researchers said blueberries affected the genes that help cells burn and store fat and utilize glucose efficiently.

Melatonin reduced weight, sped metabolism, improved blood fats

In this study, young overweight rats consumed a diet including an experimental mega-dose of melatonin, or no melatonin. After six weeks, the melatonin group had gained less weight than the non-melatonin group. The melatonin group also saw triglycerides decrease 27 percent, LDL cholesterol decrease 20 percent, and HDL–the good cholesterol—increase 26 percent.
