Med diet: obviously not only olive oil!

It is of great interest to read that med diet is difficult to follow in UK for several reasons--namely, availability, prices and taste of med nutrients. Except for taste, it seems to me that these obstacles are the same on the continent, especially in urban areas either in med countries or other non med countries even Spain. To explain that one must describe the main obstacle to consuming a med diet and which is widely underestimated in the comments.

The production of agriculture and breeding were so deeply transformed since WWII, that our food environment is completely different. We don't eat grassfed meat but processed products made of cornfed sedentary obese animals heavily transformed by heating, mincing, mixing, sterilising and so on. Wild meat is below 10% of fat and crops are now > 25% fat.

We know that processed meat and saturated fats are a recognised factor for colon cancer and other chronic diseases. We don't eat the same ceareals because they are now products made of refined corn or wheat, high temperature cooked, sugared, mixed with trans fats, with added multivitamins. Consumption of high GI foods and fructose is clearly associated with D2.

We don't eat the same olive oil because med populations consume olives, non refined olive oil and a lot of wild greens or crops naturally rich in alphalinoleic acid. Instead at best we buy white salads like the iceberg one which is depleted in phytonutrients and alphalinoleic acid and we pour on it sunflower oil which is pure W6 linoleic acid. Consequently a dramatic change has occurred in the W6/W3 ratio of PUFA which is in favor of inflammation--a common final pathway of chronic diseases.

We don't eat the same dairy products because more than 80% of them are sugared, flash pasteurised, and made with milk from cow fed cornstarch...

These kind of examples are endless.

But the question is: Why do we consume these foods? Is it a clear choice or a mandatory buying in the different supermarkets which sell the same industrialised products? Clearly the anwer is: the agrofood industry and the low cost of goods transportation (at least until oil reaches new unsustainable prices) had standardised food in a way which is not compatible with our genome. It is impossible for our genome to adapt in only fifty years... Med diet for all demands a change in agriculture and breeding. The recent policies toward more sustainable and energy efficient farming are in favor of the med diet. Other changes need to occur and it seems to me that medicine must take charge of them.

For closure I remenbered that I sent several years ago this comment in a poetic form about the polypill controversy which cannot compete in my view with med diet :

Polypill a life...in

Instead of delicious butter margarin

For bad cholesterol statin

For thick blood aspirin

For diabetes metformin

For high blood pressure nicardipin

As I stop smoking a full patch of nicotin

And tomorrow a nightmare, imagine !

Don’t be foolish !

Take fresh spinach and fatty fish

Roquette, nuts, kiwis and have a large meal

Pour your glass with wine and make a deal

After a snap I will go running

Work a bit and get light dining

Smoke a big havana once a year

And forget doctors for ever
