Enhancements to current dietary advice to prevent chronic disease are of great clinical and public health importance. The OmniHeart Trial compared 3 diets designed to reduce cardiovascular disease CVD risk—one high in carbohydrate and 2 that replaced carbohydrate with either unsaturated fat or protein. The lower carbohydrate diets improved the CVD risk factors. Several popular diets claiming health benefits emphasize carbohydrate, fat, or protein or various combined approaches. The objective of this study was to compare the macronutrient contents of the OmniHeart trial diets to those of several popular diets and to evaluate each diet for consistency with national health guidelines. The OmniHeart diets were generally consistent with national guidelines to prevent cancer, diabetes, and heart disease, whereas most popular diets had limitations for fulfilling one or more guidelines. Although the OmniHeart protein and unsaturated fat diets were superior to the carbohydrate diet in improving CVD risk, all 3 study diets were consistent with national guidelines to reduce chronic disease risk, which suggests that the guidelines might now be fine-tuned to optimize disease prevention. Popular diets vary in their nutritional adequacy and consistency with guidelines for risk reduction. These guidelines were designed to move beyond ensuring adequacy, ie, determining an Adequate Intake AI of these nutrients and to address the relation of macronutrients to chronic disease in the context of adequate physical activity and energy expenditure to maintain a healthy weight 1.
Low-carbohydrate diets LCDs have regained popularity in recent years, but public awareness and perceived healthfulness of LCDs have not been explored. We describe population awareness, use, and perceptions of the healthfulness of LCDs and examine differences by sociodemographic and communication variables. Nationally representative data from the Health Information National Trends Survey HINTS were analyzed by using multivariate logistic regression to examine independent correlates of awareness, use, and perceptions of the healthfulness of LCDs. Independent correlates of awareness included being a college graduate, being non-Hispanic white, and having a high body mass index BMI. One-third of respondents who were aware of LCDs agreed that they are a healthy way to lose weight. Independent correlates of perceived LCD healthfulness included not being a high school graduate and being likely to change behavior in response to new nutrition recommendations. This study is among the first to explore correlates of awareness, use, and perceptions of LCDs in a nationally representative sample. Despite high levels of awareness of LCDs, these diets are not used frequently and are not perceived as being healthy. Since the publication of Dr. In recent years, LCDs have regained popularity, as evidenced by the publication of such books as Dr. In , dietary experts from government, academia, and industry convened the International Life Sciences Institute North America Technical Committee on Carbohydrates to review scientific evidence about the healthfulness of LCDs.

One adult from each household was selected for an interview, which was conducted in English or Spanish on the basis of respondent preference. Abstract Introduction Low-carbohydrate diets LCDs have regained popularity in recent years, but public awareness and perceived healthfulness of LCDs have not been explored. Differences in energy intake, lipids including log transformation for TG analysis, lipoproteins and other biochemical measurements before and after each dietary phase were analyzed using STATA Statistical Data Analysis software version 8. Flow-mediated dilatation is impaired by a high-saturated fat diet but not by a high-carbohydrate diet. Notably, in the one large trial that collected a detailed symptom diary, those in the Atkins trial arm reported more episodes of constipation, headache, halitosis, muscle cramps, diarrhea, and general weakness than did those in the low-fat arm 27, which may limit the general applicability of such a diet in clinical practice. Weight-loss plans were selected because of their status on the New York Times Bestseller list during the past 5 years. Compared with a typical diet, all Omni diets lowered LDL cholesterol, but the Omni-Protein diet showed a greater reduction than did the Omni-Carb diet, and the triacylglycerol-lowering effect was stronger for protein than for unsaturated fat, which suggested that a specific beneficial effect of protein on lipid risk factors Although nutrient intake is directly dependent upon energy, adjusting the AHEI scores by energy content resulted in only a slight reordering of the plans. Completing a full systematic review on each nutrition fact might have strengthened the findings, but we found publications in high-quality journals that gave an indication of the recently reported data using our review method. Brachial artery flow mediated endothelial dependent vasodilation FMD was measured using an MHz broadband linear-array transducer and baseline images were acquired after a minute supine equilibration period as previously described Recent metabolic studies showed detrimental effects of trans fat on inflammatory factors and indicators of insulin resistance
