$name[$x] | Tuesday, December 03, 2002 Controlling Homocysteine Levels $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_12_01_nutritionarchive.php#90009519"; ?> This study of 1139 women and 931 men (healthy French adults) concludes that for women, decreasing coffee and alcohol consumption may be the best way to lower homocysteine levels. For men, increasing physical activity, dietary fiber, and folate intake were the strongest predictors of a lower homocysteine level. Comment: vitamin supplementation probably is beneficial in both men and women in lowering homocysteine levels, although a statistically significant association was not found in the women.

The volunteers were allowed to eat as much as they wanted, but their initial serving size was varied. When the volunteers were presented with a large initial serving size, they ended up eating more than when presented with a small initial serving size (even though they could eat as much as they wanted). Comment: want to lose weight? Try serving yourself a smaller initial serving size of food when you sit down to eat. This is a good idea for families as well. When dishing up the meal, give everyone a small serving size initially. [ AJCN -- Abstracts: Rolls et al. 76 (6): 1207 ] Tuesday, November 12, 2002 Betaine Supplementation Lowers Plasma Homocysteine $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_11_01_nutritionarchive.php#85668053"; ?> This study found that supplementation with betaine at 6 g/d slightly decreased plasma homocysteine levels. Comment: an excellent overview of the relationship between heart disease and homocysteine can be found HERE. At this point, it seems that daily supplementation with a multivitamin containing at least 200 ug of folate is a reasonable strategy to reduce plasma homocysteine levels. The use of betaine is an interesting, but still experimental, intervention. [ AJCN -- Abstracts: Schwab et al. 76 (5): 961] Wednesday, October 02, 2002 Artificial Sweeteners Decrease Weight, Body Fat, and Blood Pressure $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_10_01_nutritionarchive.php#85516081"; ?> This study looked at 41 overweight men and women, and divided them into two groups. One group drank regular beverages (containing sucrose; the sucrose supplement group) and the other drank beverages containing artificial (zero calorie) sweeteners (the artificial sweetener supplement group). Those in the artificial sweetener supplement group after 10 weeks had a lower body weight, lower body fat, and a lower blood pressure compared to the sucrose group. Comment: This study suggests that drinking diet pop (if you drink pop at all) has significant benefits over drinking regular pop in terms of blood pressure, body weight, and body fat. [ AJCN 2002;76 (4): 721] Saturday, September 14, 2002 The Effect of Diet on the Risk of Cancer $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_09_01_nutritionarchive.php#85450708"; ?> This review on the effect of diet and cancer concludes that a diet rich in fruit, vegetables and cereals most likely helps prevent several types of cancer. Also important is maintaining a healthy bodyweight, regular physical activity, and a restriction on the consumption of alcohol. The authors state that diet-related factors are thought to account for about 30% of cancers in developed countries. [ Lancet 2002; 360: 861-68 ] click here for more medical news and commentary...
