Just back from 5 days of the American Aging Association meetings in Ft. Worth, TX. One exciting finding – 1 glass of red grape juice daily dramatically restores cogitive impairment in the “elderly” (over 55?).

THE JOURNAL of NUTRITION ARTICLES THIS MONTH – Summeries, see stories below:

1. Elderly (over 65) benefit from dietary supplements – Even in affluent Western countries, vitamin inadequacy is widespread even in healthy elderly.

2. Phytosterols lower cholesterol

3. Mixed nuts and virgin olive oil lower tumor factor and heart disease risk

4. Quercetin (found in…) ameliorates metabolic syndrome, including abdominal obesity

5. Exercise protects bones better than calcium (calcium supplements are hazardous!)

6. Sympsosium on Low-calorie Sweeteners – No evidence of benefit

7. Alternative dietary guide lowers risk of chronic disease – More than 24 yrs following over 100,000 health professional men and women led to this simple table of what to eat.

THE JOURNAL of NUTRITION ARTICLES THIS MONTH

1. Elderly (over 65) benefit from dietary supplements – Even in affluent Western countries, data from dietary intake surveys indicate that vitamin inadequacy is widespread even in healthy elderly. Fortified foods and dietary supplements specifically targeted at the growing segment of healthy elderly can be a pragmatic solution.

2. Phytosterols lower cholesterol – Phytosterol-enriched foods are increasingly marketed to lower cholesterol levels and atherosclerosis in the general population. A mixed Western diet provides similar amounts of cholesterol and phytosterol, but systemic absorption is at least 10 times lower for the latter.

3. Mixed nuts and virgin olive oil lower tumor factor and heart disease risk

4. Quercetin (found in…) ameliorates metabolic syndrome, including abdominal obesity – Quercetin (found in red onions, apples, berries, citrus fruits, tea, and red wine) treatment T attenuated most of the symptoms of metabolic syndrome, including abdominal obesity, cardiovascular remodeling, and NAFLD, with the most likely mechanisms being decreases in oxidative stress and inflammation.

5. Exercise protects bones better than calcium (calcium supplements are hazardous!) – From AGE meeting, dietary supplements are hazardous and calcify aortic artery.

6. Sympsosium on Low-calorie Sweeteners – No evidence of benefit – Americans consume about 50% of their daily energy intake in the form of carbohydrates; of this, ~15% of daily energy intake is represented by added sugars (1). In 2008, ~75 g of added sugars were ingested each day, down from ~100 g/d in 2000 (1). The May 2011 report estimates that caloric sweetener use in foods and beverages rose from 137.5 lb/(person × y) [171 g/(person × d)] in 1992 to ~154 lb/(person × y) [191.5 g/(person × d)] in 1999 and then declined to 136 lb/(person × y) [169 g/(person × d)] in 2010. Short-term randomized controlled trials have shown LCS use to be BMI neutral or to have modest weight-reducing effects in overweight and obese adolescents. Evidence supporting a role for LCS in weight management is lacking.

7. Alternative dietary guide lowers risk of chronic disease – The Alternative Healthy Eating Index (AHEI), which is based on foods and nutrients predictive of chronic disease risk, is associated inversely with chronic disease risk. We assessed the risk of major chronic disease prospectively among 71,495 women from the Nurses’ Health Study and 41,029 men from the Health Professionals Follow-Up Study who were free of chronic disease at baseline during ≥24 y of follow-up.

I am of the opinion that my life belongs to the whole community, and as long as I live, it is my privilege to do for it what ever I can. I want to be thoroughly used up when I die, for the harder I work, the more I live.
