Health data-- this is a world study and not useful in that it is a world summary. Some areas of the world are still improving their diets as in getting enough; some have completely adopted the SAD; and in the US many have moved to vegan and are experiencing health problems adding to poor health as much as SAD.

Salt--that is a big subject.

Whole plant diet is still good-- keep eating real whole foods. I do. Just add in REAL meats and real fats. I have moved away from vegetable oils, decreased AS, increased water in stead of sugar free drinks.....

What are you changing? Can you be more specific?? (Are you including bacon and nitrate /BHA meats?? Yummy but has risks for cancer. )
