Health supplements are often mislabeled as having potential health benefits. Approximately 50% of newly diagnosed cancer patients start taking dietary supplements. Men’s health supplements (MHSs), which we define as supplements that are specifically marketed with the terms men’s health and prostate health (or similar permutations), are often mislabeled as having potential anticancer benefits.

Use nutrition panels, not health claims, when selecting processed food to eat.

High fructose corn syrup consumption promotes diabetes.  Short-term fructose consumption, in isocaloric exchange or in hypercaloric supplementation, promotes the development of hepatic insulin resistance in nondiabetic adults without affecting peripheral or muscle insulin sensitivity.

Hesperidin in oranges and lemons may benefit the heart.

Whey protein (dairy) consumption lowers 24 hr blood pressure.  Cardiovascular diseases (CVDs) are the greatest cause of death globally, and their reduction is a key public-health target. High blood pressure (BP) affects 1 in 3 people in the United Kingdom, and previous studies have shown that milk consumption is associated with lower BP.

Green tea lowers your total and LDL cholesterol levels.  Supplementation with green tea extract significantly reduced circulating total cholesterol (TC) and LDL-cholesterol concentrations, especially in those with elevated baseline TC concentrations. 

Eating 5g BCAA supplements aids muscle synthesis in older men [and others].  Leucine co-ingestion with daily meals enhances integrated myofibrillar protein synthesis in free-living older men in rested and exercising conditions and is equally effective in older men who consume daily protein intakes greater than or equal to the RDA. 

24 hr severe energy restriction aids weight control in lean adults. Intermittent (SER) can induce substantial weight loss in lean men and women.  In lean young adults, 24-h SER transiently elevated subjective appetite and marginally increased energy intake, but hormonal appetite markers did not respond in a manner indicative of hyperphagia. 

Water consumption is inversely correlated with obesity - drink more water. Adequate water intake is critical to physiologic and cognitive functioning. Obese people drink much less water than thinner people.  The Institute of Medicine’s adequate intake recommendations for men and women are men: ≥3.7 or <3.7 L; nonlactating women: ≥2.7 or <2.7 L; lactating women: ≥3.8 or <3.8 L for adequate or low intakes, respectively.

Childhood picky eating reduces obesity.  Girls’ picky eating in childhood is associated with normal weight status from ages 5 to 15 y. From ages 5 to 15 y, persistent picky eaters (n = 33; 18%) had lower BMI (tracking at the 50th percentile) than did nonpicky eaters (n = 148; tracking at the 65th percentile) (P = 0.02). Persistent picky eaters were less likely to be overweight into adolescence. Both groups consumed less than the recommended amounts of fruit and vegetables, although persistent picky eaters had lower intakes of vegetables than did nonpicky eaters at all time points (P = 0.02). Persistent picky eaters also received higher amounts of pressure.

Children should drink whole milk, not low fat or skim, for lower BMI.  Whole milk consumption among healthy young children was associated with higher vitamin D stores and lower BMI.
