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.’
Reading various blogs, one would expect that the bounties of the Amazon rainforest – guava, manioc and armadillo – are enough to provide all the nutrition that children need. Eating foods that are foraged is apparently the secret to good health. Top Amazonian superfoods include acai berries, raw cacao, passionfruit and sacha inchi seeds. Amazonian tribes are also reported to have the most diverse gut microbiota, with its purported health benefits. So it may be surprising to learn that indigenous populations in South America are actually at a greater nutritional risk than national populations.
