Cocoa is used in the sports world as a supplement, although there is no consensus on its use. In a new study, researchers from the Universidad Europea de Madrid and elsewhere investigated the effect of cocoa intake on intestinal ischemia, gastrointestinal symptoms, gut microbiota, and serum lipopolysaccharide levels in endurance athletes during their training period on an unrestricted diet. Tabone et al. found that cocoa had no significant effects...

You et al. shows that meat intake is positively associated with life expectancy at national level; the underlying reasons may be that meat not only provides energy but also complete nutrients to human body; from the evolutionary point of view, meat has arguably been an indispensable component in human diet for millions of years, which is evidenced, genetically, by meat digesting enzymes and digestive tract anatomy; the complete nutritional profile of meat and human adaptation to meat eating have enabled humans to gain many physical benefits, including greater life expectancy; meat intake, or its adequate replacement, should be incorporated into nutritional science to improve human life expectancy.

Scanning electron microscopy image of a nanopatterned YBa2Cu3O7−δ (YBCO) thin film. The 12-nm-thick nanopatterned YBCO thin film was fabricated by reactive ion etching through an anodic aluminium oxide (AAO) membrane directly placed atop the YBCO. By RIE, the anodized aluminium oxide pattern of a triangular array of holes with ~70-nm diameter and ~103-nm period was duplicated onto the YBCO film.
