Cutting back on meat consumption has numerous advantages, from your physical health to the well-being of the environment

It’s well known that high consumption of red meat can lead to major health issues such as diabetes, stroke, heart disease and cancer. Studies like the 2012 one out of the  Harvard School of Public Health  shows that replacing one serving of red meat weekly with one serving of nuts reduces mortality risk by 19%.

Global health can also be improved with the replacement of meat by nuts and grains.
UN studies show factory farmed animal production causes “an even larger contribution" to climate change than the transportation sector worldwide.”

A University of Oxford study out in march last year found that widespread adoption of vegetarian diet would cut food-related emissions by 63% and make people healthier too. A global switch to diets that rely less on meat and more on fruit and vegetables could save up to 8 million lives by 2050, reduce greenhouse gas emissions by two thirds, and lead to healthcare-related savings and avoided climate damages of US $1.5 trillion

Facts like this have driven the global movement of “Meatless Monday” with a simple message: Once a week, cut the meat. Started by the Johns Hopkinds Bloomberg School of Public Health it’s now entering its second decade and is embraced in 36 countries.
 Nuts, seeds and beans along with an increased consumption of fruits and vegetables will provide a well balanced meal plan on the days you go meatless.

For those dropping meat from a meal or so a week there is no worry about protein but for vegetarians counting purely on the protein from nuts to meet your protein needs, consume either legumes or dairy products as well, as these are complementary proteins which when combined with nuts contain all of the essential amino acids. You don't need to consume complementary proteins during the same meal, just at some point during the same day.
