introduction: ramadan is the holiest month in islamic calendar and muslims abstain from eating, drinking, and smoking from dawn to sunset, in which there are changes in quality of food and eating patterns. the purpose of this study was to know whether these changes provide nutritional needs, and supply all of necessary macronutrients for individuals in the month. method: a prospective observati...

Nutrition influences skin structure; however, a systematic investigation into how energy and macronutrients (protein, carbohydrate and fat) affects the skin has yet to be conducted. We evaluated the associations between macronutrients, energy intake and skin structure in mice fed 25 experimental diets and a control diet for 15 months using the Geometric Framework, a novel method of nutritional ...

15 There is lack of evidence on the differential impact of maternal macronutrient consumption: 16 carbohydrates (CHO), fats and protein on birthweight. We investigated the association between 17 maternal dietary macronutrient intakes and their sub-components such as saccharides and fatty acids 18 and birthweight. This analyses included 1,196 women with singleton pregnancies who were part of 19 ...

During this session, Joanne Lupton of Texas A&M University, former chair of the panel on macronutrients, discussed selected research recommendations covering the five types of nutrients in the Dietary Reference Intakes (DRI) Macronutrients Report (IOM, 2002/2005). Harold Kohl of the Centers for Disease Control and Prevention (CDC) addressed research recommendations pertaining to physical activi...

This review explores the potential for changes in dietary macronutrients to differentially influence mitochondrial bioenergetics and thereby the frequency of mtDNA haplotypes in natural populations. Such dietary modification may be seasonal or result from biogeographic or demographic shifts. Mechanistically, mtDNA haplotypes may influence the activity of the electron transport system (ETS), ret...

Major scholars in the field, on the basis of a 3-day consensus, created an in-depth review of current knowledge on the role of diet in cardiovascular disease (CVD), the changing global food system and global dietary patterns, and potential policy solutions. Evidence from different countries and age/race/ethnicity/socioeconomic groups suggesting the health effects studies of foods, macronutrient...

Accurate measurements of soil macronutrients (i.e., nitrogen, phosphorus, and potassium) are needed for efficient agricultural production, including site-specific crop management (SSCM), where fertilizer nutrient application rates are adjusted spatially based on local requirements. Rapid, non-destructive quantification of soil properties, including nutrient levels, has been possible with optica...

Macronutrients are essential elements for plant growth and development. In natural, non-cultivated systems, the availability of macronutrients is not a limiting factor of growth, due to fast recycling mechanisms. However, their availability might be an issue in modern agricultural practices, since soil has been frequently over exploited. From a crop management perspective, the nitrogen (N), pho...

BACKGROUND/OBJECTIVES Flaxseed has functional properties in the reduction of the risk of chronic non-communicable diseases such as cardiovascular disease, diabetes and cancer. Regardless of its high energy density, the consumption of flaxseed tends to promote body weight maintenance. The purpose of this study was to evaluate energy and macronutrient balance after flaxseed consumption. SUBJECT...

The opinions about optimal proportions of macronutrients in a healthy diet have changed significantly over the last century. At the same time nutritional sciences failed to provide strong evidence backing up any of the variety of views on macronutrient proportions. Herein we present an idea how these proportions can be calculated to find an optimal balance of macronutrients with respect to prev...
