Low vitamin D has been associated in past studies with neurovascular injury (damage to the major blood vessels supplying the brain, brainstem, and upper spinal cord). Nils Henninger, from University of Massachusetts Medical School (Massachusetts, USA), and colleagues studied 96 stroke patients, assessing their blood levels of 25-hydroxyvitamin D (a marker of vitamin D status).
The Importance of Nutrition in Mental Health
With pharmacological approaches both costly in developed nations and largely inaccessible in developing countries, scientists and public health experts are looking at nutritional approaches to address mental health issues. Jerome Sarris, from the University of Melbourne (Australia), and colleagues submit that: “Evidence is steadily growing for the relation between dietary quality (and potential nutritional deficiencies)
Red Wine Compound Raises Neurogenesis
The hippocampus – the region of the brain responsible for memory, experiences structural changes that are thought to contribute to aging-related memory and mood impairments. Ashok K. Shetty, fro, the Texas A&M Health Science Center College of Medicine (Texas, USA), and colleagues employed a lab animal model to study the potential effects of resveratrol –
Regular Exercise Revs Up Brain Health
Oxygen availability correlates to brain health and cognitive performance. Tracy A. Cameron, from the University of Otago (New Zealand), and colleagues assessed a group of 52 healthy young women for the role of regular engagement in physical activity on oxygen availability in the anterior frontal region of the brain – the area involved in completing
Green Algae a Source of Potent Anti-Fat Compound
A carotenoid from green algae known as siphonaxanthin may have a role in future non-drug approaches for weight management. Zhuo-Si Li, from Kyoto University (Japan), and colleagues employed a cell study in which cells were incubated with a solution of siphonaxanthin, with results suggesting a dose-dependent effect on fat accumulation as well as the expression
Per aiutare il cuore e prevenire l’ictus basta dieta semivegetariana
Vegetariano fa meglio. Ridurre la presenza degli alimenti di origine animale nella propria dieta ha un effetto protettivo sulla salute cardiovascolare.

Colesterolo: negli USA stop ai messaggi che limitano uova, gamberetti ecc. La quota presente nel cibo è poco importante
Dopo quarant’anni di messaggi che invitano ad evitare cibi ricchi di colesterolo, come uova e gamberetti, dagli Stati Uniti arriva il dietrofront. La decisione è stata presa dalla commissione consultiva di nutrizionisti istituita dal governo di Washington all’inizio del 2014, e incaricata di fornire pareri scientifici sulle nuove linee guida per la dieta degli americani, che
The effects of 12 weeks of beta‑hydroxy‑beta‑methylbutyrate free acid supplementation on muscle mass, strength, and power in resistance‑trained individuals: a randomized, double‑blind, placebo‑controlled study
Introduction Studies utilizing beta-hydroxy-beta-methylbutyrate (HMB) supplementation in trained populations are limited. No long-term studies utilizing HMB free acid (HMB-FA) have been conducted. Therefore, we investigated the effects of 12 weeks of HMB-FA supplementation on skeletal muscle hypertrophy, body composition, strength, and power in trained individuals. We also determined the effects of HMB-FA on muscle damage and performance during an overreaching cycle. Methods
