Dr. David Katz and Dr. Stephanie Meller recently
published their paper, titled “Can We Say What Diet Is Best for Health?” in the
journal Annual Reviews. They considered diets based on the popular
categories: low carbohydrate, low fat, low glycemic index, Mediterranean, mixed/balanced
(DASH), Paleo (cave man) and vegan. The study attempted to discover positive impacts
of these diets on life span, cancer, heart disease, metabolic syndrome, dementia
and obesity.
The authors cite existing wisdom that general quality of
life depends on “feet, forks and fingers.” That means feet (activity level),
forks (what you eat and how much you eat) and fingers (do you smoke) are the
primary predictors of how long and well you will live. Beyond that, they found no good science on the relative merits of particular diets, despite what you
might hear on Dr. Oz.
They did make some broad observations on diets in
general, saying "A diet of minimally processed foods close to nature,
predominantly plants, is decisively associated with health promotion and
disease prevention." Further, vegetarian diets with balanced nutritional
components delivered better experience for heart disease and cancer. They also
noted that the Mediterranean Diet, which includes limited wine and meat, also
delivered good results in these areas.

Another diet taking it on the chin was the Paleo, or Cave
Man Diet. They found that eating mostly meat had no positive medical benefit,
observing that the meat of cave man days is not available now, and that our
current vegetables did not exist during cave man times.
The conclusion of the report? There is no “best” diet.
Sigh. They say that our diet quest is damaged by “distractions associated with
exaggerated claims” and unrealistic goals.
So eat well, eat moderately, take a walk every day, and DON’T
SMOKE. You will thank yourself later.
I love the Mediterranean diet. Lots of variety and I can drink wine! Lost some weight, too.
