Vitamin and mineral overages were measured in adult MVMs, most of which already meet RDAs. Therefore, nutrient overexposures from supplements combined with typical food intake may have unintended health consequences.
It appears to be much easier to attempt to attenuate muscle loss via protein intake earlier in life rather than to try and reclaim what has been lost at the latter stages of life, which appears to be a far more difficult proposition. The protein source provided to the study participants, whey protein isolate, is one of the highest quality proteins with a high leucine content. The determination of protein requirements (need) and “optimal” protein intakes (greater than need but beneficial to health) is complex and currently, insofar as older persons are concerned, without consensus. Observational studies have shown associations between higher protein intakes and preservation of lean mass as well as muscle function (5). Moreover, there is evidence that shows that protein needs are actually substantially higher than the RDA for older persons.
Hyperactive Wnt signaling is frequently observed in colorectal cancer. Higher intakes of dietary fiber [nondigestible carbohydrates (NDCs)] and the fermentation product butyrate are protective against colorectal cancer and may exert their preventative effects via modulation of the Wnt pathway.
We aimed to examine the association of CVD mortality with the intake of natto, soy protein, and soy isoflavones in a population-based cohort study in Japan. Data suggest that natto (soy) intake may contribute to the reduction of CVD mortality.
We studied participants from the Jackson Heart Study, an African-American adult cohort.
Low-normal potassium is a risk factor for diabetes and may account for some of the racial disparity in diabetes risk.
We investigated the associations of cholesterol and egg intakes with incident dementia, Alzheimer disease (AD), and cognitive performance in middle-aged and older men from Eastern Finland. Moderate egg intake may have a beneficial association with certain areas of cognitive performance.
Bone mineral content (BMC) and bone mineral density (BMD) are positively correlated with dietary protein intakes, which account for 1–8% of BMC and BMD variances. These results, which were recorded in a very homogeneous population of healthy postmenopausal women, indicate that there is a beneficial effect of animal and dairy protein intakes on bone strength and microstructure.
