Nutrition experts contend that all we need is what's typically found in a routine diet. Industry representatives, backed by a fascinating history, argue that foods don't contain enough, and we need supplements. Fortunately, many excellent studies have now resolved the issue.(SLAtlantic)
An in-depth talk at Google that sums up the scientific research on living a healthy life with lots of practical advice.
An exceptionally informative, nicely designed and useful nutrition database, where you can easily look up the glycemic load, inflammation factor, vitamins, proteins, nutrients, calories etc. It is a practical source of information if you wish to either shed excess poundage or put some on.

From the mid 40s to the mid 50s Coronet Instructional Films were always ready to provide social guidance for teenagers on subjects as diverse as dating, popularity, preparing for being drafted, and shyness, as well as to children on following the law, the value of quietness in school, and appreciating our parents. They also provided education on topics such as the connection between attitudes and health, what kind of people live in America, how to keep a job, supervising women workers, the nature of capitalism, and the plantation System in Southern life. Inside is an annotated collection of all 86 of the complete Coronet films in the Prelinger Archives as well as a few more. Its not like you had work to do or anything right? [more inside]
Are Healthy Foods Really More Expensive? (6.78 MB PDF) It turns out that it depends on how you measure the price. In a recent study by the USDA, some 4,439 foods were compared using the following metrics: the price of food energy ($/calorie), the price of edible weight ($/100 edible grams), the price of an average portion ($/average portion), and the cost of meeting the federal dietary recommendations for each food group. The study found that for all metrics except the price of food energy ($/calorie) healthy foods cost less than less healthy foods (defined as foods that are high in saturated fat, added sugar, and/or sodium, or that contribute little to meeting dietary recommendations).
The known knowns, known unknowns, and perhaps even the unknown unknowns of why a calorie is not a calorie.
Nichelle Gainer (whose Vintage Black Glamour blog was seen previously on MeFi) responds insightfully to a NY Times editorial by author Alice Randall called "Why Black Women Are Fat."
Food Fight: Does Healthy Food Have to Be More Expensive? In which the blog Get Rich Slowly chronicles an argument about nutrition vs cost and then invites readers to chime in.
My favorite response to questions about how to eat clean is, “Wash your food.” On the always-changing understanding of ‘good’ food and how some of the bodybuilding community’s dogma doesn’t hold up to research.
Obesity Epidemic Grows: [CNN.com] "Two-thirds of all adults and about a third of all children and teenagers in the United States are overweight or obese according to a report release Thursday by the Trust for America's Health (TFAH) and the Robert Wood Johnson Foundation (RWJF). According to "F as in Fat: How Obesity Threatens America's Future 2011,"[PDF] adult obesity increased in 16 states during the past year and rates soared to 30% or more in these 12 states: Alabama, Arkansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Oklahoma, South Carolina, Tennessee, Texas, and West Virginia. Four years ago, only one state - Mississippi - had an adult obesity rate of more than 30%. No state showed a decrease in it obesity rate in Thursday's report."
Why Wal-Mart Is Making Our Health Its Problem - "So what's behind the [healthier-eating] initiative? In a word: scale. In a recent article in HBR, Chris Meyer and I argued that we'll see companies taking more and more ownership of externalities they could ignore because of changing sensibilities and better sensors (meaning detection and reporting of impacts by third parties). But we also identified a third driver: the scale of modern business. Whereas in the past, a single grocer could not have much impact on society, in today's highly consolidated market, Wal-Mart touches a significant percentage of the nation's food intake. Once you reach a scale where your decisions have ramifications for millions, it is hard to pretend that the impacts, even as distant ripples, are not your problem."

A new study suggests that you will gain more weight if you eat meat, even if you eat the same amount of calories as someone who eats less meat. It might be a good idea to cancel that meat party. [more inside]

Mistress Krista says: Only YOU can stop gym dorkery! Stumptuous, one of AskMe's favourite fitness sites, has both a spiffy new design and a bunch of new content (Why your excuses are crap; Lies in the gym; Things you should not lift if you want to look like Madonna). Beginners will find plenty of smart and blunt information about eating, starting and refining a training program, avoiding and recovering from injuries, and developing a home gym one way or another. But Stumptuous has also extended its domain to YouTube. Part of the original Dork to Diva web series on correct technique is now up at YT (deadlifts; biceps curl) thanks to the support of The Prevention of Gym Idiocy Society (Ladies' Auxiliary), but you can also find some more unorthodox exercise ideas.
Feeding Minds - the impact of food on mental health
USDA releases new food pyramid(s). Instead of one cogent nutritional guideline for all Americans, the USDA has released a dozen because "one size doesn't fit all." Dietitians have advocated revision for a while now but change has been slow. According to author Marion Nestle, the nutritional guidelines have become highly politized by industry lobbyists: "My first day on the job, I was given the rules: No matter what the research indicated, the report could not recommend 'eat less meat' as a way to reduce intake of saturated fat." Newspeak for sweets appears to be discretionary calories; are we doing any better?
Supersized in the NFL Analyzing data from the 2003-2004 season, researchers say "more than a quarter of NFL players had a body mass index that qualified them as class 2 obesity" -- equivalent to a 6-foot man weighing between 260 and 300 pounds. Even those players weren't the biggest ones: the study counted more than 60 players -- 3 percent -- with body mass indexes placing them into class 3 obesity, with individual weights approaching 400 pounds. "I don't know what's going on in the minds of coaches", said lead researcher Dr. Joyce Harp, an assistant professor of nutrition and medicine at the University of North Carolina at Chapel Hill. Players' growing girth "is a major concern," said Dr. Arthur Roberts, a former NFL quarterback and retired heart surgeon (.pdf file) whose Living Heart Foundation works with the players' union to evaluate heart-related health risks faced by current and retired players.

NutritionData.com is a free and very useful website for detailed nutrition information, including the in-vogue Glycemic Index; their own Fullness Factor, a measure of how filling foods are per calorie; and others. Their Better Choices Diet makes use of the Fullness Factor to make consuming less energy than you use easier to do without going hungry. Previously mentioned in response to this AskMe question.
Coffee is Good, Good, Good. Coffee is Bad, Bad, Bad. Seems like the experts just don’t know if our most common addiction is, well, good for us, or bad for us.
The vegan diet can be a killer, at least that's what the State of New York thinks. Was a "strict vegan diet" the cause of a 15-month-old's demise or did New York health officials have a hand in the death?
Keys of Nutrition You may not be familiar with Ancel Keys, but his discoveries about nutrition and health are behind much of the dietary advice people now receive. Have you ever wondered who proved that the amount of cholesterol in food did not influence the amount of cholesterol in the blood? Do you know what causes high cholesterol? Do you like olive oil but need a good rationalization to keep using it? (hint: there is one) What dietary advice has most fascinated you, or helped you the most?
"We think of an orange as a constant, but in reality it's not." Canadian study finds that fruits and vegetables have lost much of their nutritional value in the last decades--potatoes, for example, have lost 100% of their Vitamin A. The reason, it appears, is mass production and a market that values appearance over substance. Is this symptomatic of deeper problems within a system where produce travels so far before reaching the consumer? Here in B.C., for example, the stores are full of California produce, despite the fact that we grow much the same fruits and vegetables locally.
