Let's eat salad!
... a combined fruit and vegetable consumption of more than 569 grams per day reduces the risk of mortality by 10% and delays the risk of mortality by 1.12 years compared to a consumption of less than 249 grams per day.Furthermore, for every 200 gram increase in daily fruit and vegetable consumption, the risk falls by 6%.
Previous studies already noted that fruit and vegetable consumption, in accordance with the recommended daily allowance, prevents the development of chronic diseases, and reduces the risk of mortality by 10-25%.
Considering fruit consumption separately, no significant risk reduction was observed, whereas vegetable consumption alone was associated with a lower risk of mortality, which was even more significant for raw vegetables: high consumption reduces the risk of mortality by 16%. [emphasis mine]
Note, snow peas should be parboiled before being added to salad. Beans and peas contain heat-labile toxin.
I need to eat more vegetables myself
I don't know about vegan, and I sure am not doing all raw, but I have been making an effort of late to include more fruit and veg in our diet, both for health and weight.
