Healthier and sustainable diet

I had always suggested my patients to eat more fruits and vegetables and legumes and grains.
Here are some benefits,as I  downloaded from Meatlless Mondays.
 About 1,850 gallons of water are needed to produce a single pound of beef.5
To grow one pound of vegetables, it takes 39 gallons of water.
Beef produces a total of 30 kg of greenhouse gas (GHG) per kg of food, while carrots, potatoes and rice produce .42, .45 and 1.3 kg GHG per kg of food, respectively.6
It takes 25 kilocalories of fossil fuel energy to produce 1 kilocalorie of all meat based protein, as compared with 2.2 kilocalories of fossil fuel input per 1 kilocalorie of grain based protein produced.7
If we used grain to feed people following a vegetarian diet, instead of using it for animal feed, it would be enough to feed about 840 million people.
