Human diet planning is generally carried out by selecting the food items or groups of food items to be used in the diet and then calculating the composition. If nutrient quantities do not reach the desired nutritional requirements, foods are exchanged or quantities altered and the composition recalculated. Iterations are repeated until a suitable diet is obtained. This procedure is cumbersome a...

Notwithstanding a growth in popularity and consumption of gluten-free (GF) food products, there is a lack of substantiated analysis of the nutritional quality compared with their gluten-containing counterparts. To put GF foods into proper perspective both for those who need it (patients with celiac disease) and for those who do not, we provide contemporary data about cost and nutritional qualit...

in recent decades, biotechnologists have striven to improve the quantity and quality of food supply. producing genetically modified (gm) foods is one of the main goals and many countries all over the world have approved the distribution and consumption of the labeled gm foods in their own regions. however, there are still few groups having concerns about allergenicity of gm foods. this review h...

Primate field studies often identify "lean seasons," when preferred foods are scarce, and lower-quality, abundant foods (fallback foods) are consumed. Here, we quantify the nutritional implications of these terms for two diademed sifaka groups (Propithecus diadema) in Madagascar, using detailed feeding observations and chemical analyses of foods. In particular, we sought to understand 1) how ma...

Is There a Problem with Genetically Modified Foods? What’s in a name? Ask genetically modified (GM) foods. They go by many names, ranging from the sinister (“Frankenfoods”) to the adoring (“super crops”), depending on who’s doing the naming. Although there are clear benefits to the use of this techn o l o g y — f o r example, genetic modification could reduce the amount of allergenic substances...

BACKGROUND Healthy diets are supposed to be more environmentally friendly because they rely mainly on plant-based foods, which have lower greenhouse gas emissions (GHGEs) per unit weight than do animal-based foods. OBJECTIVES The objectives were to estimate the GHGEs associated with the consumption of self-selected diets in France and to analyze their relation with the nutritional quality of ...

In recent years, a growing interest from consumers to know the origins and contents of foods has put alternative choices, such as organic foods and dietary changes, on the agenda. Dietary choices are important to address, as many studies find that activities related to food production account for nearly 20–30% of anthropogenic greenhouse gas (GHG) emissions. Nonetheless, while GHG emissions are...

BACKGROUND Evidence supports that television food advertisements influence children's food preferences and their consumption. However, few studies have examined the extent and nature of food marketing to children in low and middle income countries. This study aims to assess the nutritional quality of foods and beverages advertised on Mexican TV, applying the Mexican, World Health Organization (...
