AJCN July, 2016 from Roc Nutrition Investigator

Twelve weeks of EGCG+Resveratrol supplementation (282 and 80 mg/d, respectively) 
increased mitochondrial capacity and stimulated fat oxidation compared with placebo,

Meal regularity appears beneficial for weight management and metabolic health. The 6-7 yr intervention was part of a randomized controlled trial on the prevention of knee osteoarthritis study.

Most mature people need to drink more water.  58.1% of people over 65 had serum osmolality consistent with impending dehydration or dehydration.

We show, for the first time to our knowledge, that epicatechin intake is inversely related to CHD mortality in elderly men and to CVD mortality in prevalent cases of CVD. Best sources are green tea, dark chocolate/cocoa, dark fruits and berries.  Data from the University of California Davis indicate that 100 grams of brewed green tea contain 2.6 milligrams of catechin, 8.3 milligrams of epicatechin and 114.3 milligrams of epigallocatechin, epicatechin gallate and EGCG. The same amount of brewed black tea contains 1.5 milligrams of catechin, 2.1 milligrams of epicatechin and 23.1 milligrams of epigallocatechin, epicatechin gallate and EGCG.

Vitamin D deficiency may contribute to ulcerative colitis inflammation by disrupting epithelial barrier function.

 There are significant inverse relations between whole-grain intake and mortality due to any cause, CVD, or cancer.

These data suggest that higher phosphatidylcholine consumption is associated with 15% increased all-cause and CVD mortality in the US population.  Meat and fish are sources of phosphatidylcholine.

Resistant starch amounts in modern processed foods are low, which could explain the increase in conditions such as colorectal cancer as a result of a simple short-chain fatty acids
 deficiency. Free-living volunteers who consumed RS or a probiotic had a lower hedonic appeal of pictures of high-energy food and ad libitum energy consumption of a test meal.

Exercise is good for health, though exercise and diet have little long term effect on weight.  A long-lasting intervention effect on change in physical activity was found, which increased over time. For weight change, smaller differences were found, which decreased over time.

Among community-dwelling older adults, FV consumption was associated with a lower short-term risk of frailty in a dose-response manner, and the strongest association was obtained with 3 portions of fruit/d and 2 portions of vegetables/d.

Caffeine intake may be associated with reduced testosterone and improved menstrual cycle function in healthy premenopausal women.

Vitamin C supplement use (ever compared with never) was not associated with breast cancer risk overall; it was associated with 32% higher breast cancer risk in women in the fourth quartile of vitamin C intake from foods.
