A new study, published in the International Journal for Vitamin and Nutrition Research, shows that vitamin E status is inadequate in a high proportion of the global population. Only 21% of the studied population groups reach an adequate serum level. The assessment is the first of its kind to review over 170 publications worldwide on studies into vitamin E intake levels and serum concentrations.
The last 3 months of pregnancy is a period of rapid increase in brain volume of an infant. It is a time when docosahexaenoic acid (DHA) accumulates in the brain and eye of the developing child. Because humans are extremely inefficient at converting α-linolenic acid (ALA) to DHA, it is important for women, especially when pregnant or lactating, eat seafood or use dietary supplements to obtain adequate amounts of DHA.
The Kansas University DHA Outcomes Study (KUDOS) examined the effect of supplementing 600 mg DHA per day
If you live in North America, you can expect to see fireworks this weekend as both Canadians and Americans will be celebrating. Several years ago, my wife and I were flying across the US on July 4th and we could see fireworks below our plane as it descended into Newark airport. We were awed by the contrasting explosions of bright colors against the darkening skies below us. Our visual acuity was aided by xanthophyll carotenoids concentrated in the macula of the retina.
Based on double-digit growth in sales of organically produced goods, you might think organic foods are healthier choices than conventional foods. Especially given the price premiums for organic products (see USDA Organic Market Overview). Baudry and colleagues investigated the relationships between nutrition and health from 28,245 participants of the NutriNet-Sante study using a semi-quantitative, organic frequent food questionnaire (FFQ) with 264 foods items.
For each every food item consumed, participants were asked “How often was the product of organic origin”?
In a JAMA viewpoint, the opening sentence claims the US obesity epidemic costs $190 billion in health care expenditures annually. That is a tremendous cost to society and individual quality of life. Malik and associates explain the new changes to the nutrition and supplements facts panels along with the new Reference Amounts Customarily Consumed (RACCs) and serving sizes. The authors write ‘Careful monitoring of how food manufacturing changes in response to the label changes will be an important step in ensuring nutritional quality of food products.’
