I'm only going to bring up the life expectancy part, but latino people also live longer despite their cuisine not being the healthiest. I'm not saying that all latinos eat a terrible diet, but the cuisine we all know and love is high-carb and high in saturated fats compared to the olive oils, fishies, and veggies we see in the mediterranean diet.

Metabolic diseases are a different story. But I guess love and family cancel that out.
