NEW YORK (Reuters Health) - Supplements containing soy isoflavones may do little to preserve women's bone mass after menopause.

In a study of more than 200 women ages 46 to 65, researchers found that the soy supplement did not appear to ward off bone-density loss over 3 years. In general, women on the supplement showed the same degree of bone loss as those given a placebo -- though there was some evidence that a higher dose helped protect bone density in the hip.

The findings, reported in the American Journal of Clinical Nutrition, add to a conflicting body of research on soy and postmenopausal bone health.

Some studies have suggested that soy-based foods, isolated soy protein or isoflavone-containing supplements may be beneficial, while others have found no advantage.

Isoflavones are natural chemicals found in soybeans and certain other plant foods that are structurally similar to estrogen, and may have certain estrogen-like effects in the human body. Since declining estrogen levels after menopause spur bone-density loss, isoflavone supplements could theoretically protect women's bone mass.

The current findings, however, do not support that theory."

Egg breakfast enhances weight loss.

Conclusions
The egg breakfast enhances weight loss, when combined with an energy-deficit diet, but does not induce weight loss in a free-living condition. The inclusion of eggs in a weight management program may offer a nutritious supplement to enhance weight loss.

July 16, 2008 — Both a low-carbohydrate diet or a Mediterranean-style diet may be "effective alternatives" to a low-fat diet, with more favorable effects on lipids and/or glycemic control, new research suggests [1]. The two-year study, which managed to keep almost 85% of the 322 study participants on one of the three diets for the entire period, offers the hope that weight-loss diets can be tailored to personal preferences, without sacrificing efficacy, researchers say.

"Several recent one-year dietary studies have led the American Diabetes Association to state in January 2008 that low-carb diets should be considered for a maximum of one year," lead author on the study, Dr Iris Shai (Ben Gurion University of the Negev, Beer-Sheva, Israel), told heartwire . "The current two-year study suggests that one low-fat diet doesn't fit all, meaning that the old paradigm should be reconsidered."

Shai and colleagues publish the results of the Dietary Intervention Randomized Controlled Trial (DIRECT) in the July 17, 2008 issue of the New England Journal of Medicine

"(WebMD) Eating a low-fat vegan diet may be better at managing type 2 diabetes than traditional diets, according to a new study.

Researchers found 43 percent of people with type 2 diabetes who followed a low-fat vegan diet for 22 weeks reduced their need to take medications to manage their disease compared with 26 percent of those who followed the diet recommended by the American Diabetes Association (ADA).

In addition, participants who followed the vegan diet experienced greater reductions in cholesterol levels and weight loss than those on the other diet."

"People with coeliac disease may be more susceptible to osteoporosis because their own immune system attacks their bone tissue, a study suggests.

Plasma calcidiol, season, and serum parathyroid hormone concentrations in healthy elderly men and women.
Dawson-Hughes B, Harris SS, Dallal GE.
Am J Clin Nutr. 1997 Jan;65(1):67-71.
PMID: 8988915

Plasma calcidiol and serum PTH concentrations were inversely related, with PTH rising slowly as calcidiol concentrations declined below 110 nmol/L (95 CI: 60, 168 nmol/L). More than 90% of the men and women had calcidiol concentrations below this value in the wintertime. The high prevalence of lower wintertime calcidiol values may increase risk of bone loss in elderly men and women.

Weight loss with a low-carbohydrate, Mediterranean, or low-fat diet.

N Engl J Med. 2008 Jul 17;359(3):229-41.
PMID: 18635428

Conclusions Mediterranean and low-carbohydrate diets may be effective alternatives to low-fat diets. The more favorable effects on lipids (with the low-carbohydrate diet) and on glycemic control (with the Mediterranean diet) suggest that personal preferences and metabolic considerations might inform individualized tailoring of dietary interventions.

This week sees the publication of yet another study showing the superiority of the low-carbohydrate diet as compared to the low-fat diet. This study, published in the prestigious American Journal of Clinical Nutrition, demonstrates that subjects following the low-carb diet experience a decrease in triglyceride levels and an increase in HDL-cholesterol (HDL) levels; and that these changes are accompanied by a minor increase in LDL-cholesterol (LDL), which prompts the authors to issue a caveat.

Yes, although just about all the parameters that lipophobes worry about improved with the low-carb diet, the small increase in LDL has caused great concern and has prompted the authors to gravely announce that this small increase is troublesome and should be monitored closely in anyone who may be at risk for heart disease. Since most people who go on low-carb diets do so to deal with obesity issues, and since obesity is a risk factor for heart disease, it would appear that this small increase in LDL often seen in those following a low-carb diet could put these dieters at risk. Does it? We’ll see.

ScienceDaily (Mar. 4, 2009) — Any diet will do? Not if you want to lose fat instead of muscle. Not if you want to lower your triglyceride levels so you'll be less likely to develop diabetes and heart disease. Not if you want to avoid cravings that tempt you to cheat on your diet. And not if you want to keep the weight off long-term.

"Our latest study shows you have a better chance of achieving all these goals if you follow a diet that is moderately high in protein," said Donald Layman, a University of Illinois professor emeritus of nutrition. The research was published in the March Journal of Nutrition.
