How the Mediterranean diet can add 3 years to your life... even if you don't start until you're 70 (?)

A load of old cobblers in the article below. Difficult to know where to start but I was amused to read in the journal abstract (also below) that they got their results by using "a refined version of the modified Mediterranean diet index". First you modify your index then you refine it to get the results you want, apparently.

I was however impressed that they went to great trouble to validate their diet questionnaire. Validation is routine in psychology but rare in medicine. None of the validation methods used would have distinguished Mediterranean from non-Mediterranean diets, however. The authors themselves admit the fallibility of their methods by excluding some "implausible" diet claims from their analysis. One wonders if some bias might have crept into that process.

Anyway, as usual, the results are explicable by social class. Middle class Swedes are more likely to say they eat the "correct" foods (whether they do or not) than working class ones are. And middle class people have better health anyway.

I note also that the failed but indestructible antioxidant theory is invoked.

And finally, how do they explain the fact that a traditional Australian diet is about as "incorrect" as you can get yet Australians live longer than Greeks? There are an amazing number of nonageneraians tottering around Australia who grew up on very fatty food accompanied by a few vegetables that had been boiled to death.


The traditional diet favoured in Greece, Spain and Italy provides a great health boost no matter when you switch. No one doubts that following a Mediterranean diet is the healthy option.

But researchers have calculated the regime could add an extra three years to your life. They say it is a rich source of chemicals called anti-oxidants that fight cancer, heart disease and can slow the ageing process.

Scientists who studied the eating habits of 1,200 over-70s found that those following a Mediterranean-style diet tended to live for two or three years longer. They examined surveys which had been carried out by all the adults on their eating habits.

This contained details of how much fruit, vegetables, cereals, meat and fish they ate as well as how much alcohol they drank.

Elderly men and women have been recruited for the rolling research programme since the 1970s. Those taking part were contacted by researchers every few years to find out about their general health.

The team from Sweden’s University of Gothenburg found participants whose eating habits followed a Mediterranean style diet were 20 per cent more likely to be alive eight years later. They calculated that on average these individuals lived for between two and three years longer than those who had a different eating regime.

The diet was inspired by traditional eating habits of Greece and Southern Italy, hence its name.

Does the Mediterranean diet predict longevity in the elderly? A Swedish perspective

By Gianluca Tognon et al.

Abstract

Dietary pattern analysis represents a useful improvement in the investigation of diet and health relationships. Particularly, the Mediterranean diet pattern has been associated with reduced mortality risk in several studies involving both younger and elderly population groups. In this research, relationships between dietary macronutrient composition, as well as the Mediterranean diet, and total mortality were assessed in 1,037 seventy-year-old subjects (540 females) information. Diet macronutrient composition was not associated with mortality, while a refined version of the modified Mediterranean diet index showed a significant inverse association (HR=0.93, 95% CI: 0.89; 0.98). As expected, inactive subjects, smokers and those with a higher waist circumference had a higher mortality, while a reduced risk characterized married and more educated people. Sensitivity analyses (which confirmed our results) consisted of: exclusion of one food group at a time in the Mediterranean diet index, exclusion of early deaths, censoring at fixed follow-up time, adjusting for activities of daily living and main cardiovascular risk factors including weight/waist circumference changes at follow up. In conclusion, we can reasonably state that a higher adherence to a Mediterranean diet pattern, especially by consuming wholegrain cereals, foods rich in polyunsaturated fatty acids, and a limited amount of alcohol, predicts increased longevity in the elderly.

Michelle Obama's Unsavory School Lunch Flop

The road to gastric hell is paved with first lady Michelle Obama's Nanny State intentions. Don't take my word for it. School kids in Los Angeles have blown the whistle on the east wing chef-in-chief's healthy lunch diktats. Get your Pepto Bismol ready. The taste of government waste is indigestion-inducing.

According to a weekend report by the Los Angeles Times, the city's "trailblazing introduction of healthful school lunches has been a flop." In response to the public hectoring and financial inducement of Mrs. Obama's federally subsidized anti-obesity campaign, the district dropped chicken nuggets, corn dogs and flavored milk from the menu for "beef jambalaya, vegetable curry, pad Thai, lentil and brown rice cutlets, and quinoa and black-eyed pea salads."

Sounds delectable in theory. But in practice, the initiative has been what L.A. Unified's food services director Dennis Barrett plainly concludes is a "disaster." While the Obama administration has showered the nation's second-largest school district with nutrition awards, thousands of students voted with their upset tummies and abandoned the program. A forbidden-food black market -- stoked not just by students, but also by teachers -- is now thriving. Moreover, "(p)rincipals report massive waste, with unopened milk cartons and uneaten entrees being thrown away."

This despite a massive increase in spending on nutritional improvements -- from $2 million to $20 million alone in the last five years on fresh produce.

This despite a nearly half-billion-dollar budget shortfall and 3,000 layoffs earlier this year.

Earlier this spring, L.A. school officials acknowledged that the sprawling district is left with a whopping 21,000 uneaten meals a day, in part because the federal school lunch program "sometimes requires more food to be served than a child wants to eat." The leftovers will now be donated to nonprofit agencies. But after the recipients hear about students' reports of moldy noodles, undercooked meat and hard rice, one wonders how much of the "free" food will go down the hatch -- or down the drain. Ahhh, savor the flavor of one-size-fits-all mandates.

There's nothing wrong with encouraging our children to eat healthier, of course. There's nothing wrong with well-run, locally based and parent-driven efforts. But as I've noted before, the federal foodie cops care much less about students' waistlines than they do about boosting government and public union payrolls.

In a little-noticed announcement several months ago, Obama health officials declared their intention to use school lunch applications to boost government health care rolls. Never mind the privacy concerns of parents.

Big Government programs "for the children" are never about the children. If they were, you wouldn't see Chicago public school officials banning students from bringing home-packed meals made by their own parents. In April, The Chicago Tribune reported that "unless they have a medical excuse, they must eat the food served in the cafeteria." The bottom line? Banning homemade lunches means a fatter payday for the school and its food provider.

Remember: The unwritten mantra driving Mrs. Obama's federal school lunch meddling and expansion is: "Cede the children, feed the state." And the biggest beneficiaries of her efforts over the past three years have been her husband's deep-pocketed pals at the Service Employees International Union. There are 400,000 workers who prepare and serve lunch to American schoolchildren. SEIU represents tens of thousands of those workers and is trying to unionize many more at all costs.

In L.A., the district's cafeteria fund is $20 million in the hole thanks to political finagling by SEIU Local 99. The union's left-wing allies on the school board and in the mayor's office pressured the district to adopt reckless fiscal policies awarding gold-plated health benefits to part-time cafeteria workers in the name of "social justice." As one school board member who opposed the budget-busting entitlements said: "Everyone in this country deserves health benefits. But it was a very expensive proposal. And it wasn't done at the bargaining table, which is where health benefits are usually negotiated. And no one had any idea where the money was going to come from."

Early next year, Mrs. Obama will use the "success" of her child nutrition campaign to hawk a new tome and lobby for more money and power in concert with her husband's re-election campaign. It's a recipe for more half-baked progressivism served with a side order of bitter arugula.
