Which cuisine is the healthiest?

Probably home-made. Many cuisines can be made healthier by cooking traditional recipes after beneficial changes such as: replacing fatty meat with very lean meat, not using animal skin unless fat is scraped off, adding veggies, using much less salt/sugar, using nonfat milk/yogurt and lowfat cheese, avoiding oils & sauces, avoiding frying, etc... Restaurants don't cook this way because food wouldn't taste as "good".
