What we eat can cause or worsen diet-related illnesses and thus has a significant impact on our quality of life.

Virtually all the major scientific and medical institutions in the world agree that the risk of cardiovascular disease and stroke, obesity, osteoarthritis and osteoporosis, cancer, and diabetes, among other diseases is linked to a meat-based diet consisting of highly processed foods laden with fats and artificial ingredients. These institutions further agree that the risk is greatly reduced by adopting a healthy low-fat, high-fiber diet.

So what is the prescription for a healthier body, both now and in the future? Simple. Eat less meat, or even better give it up completely, as meat has all too often been blamed for the above mentioned diet-related illnesses, and replace it with an all-vegetarian diet. This makes sense for a number of reasons.

At the most basic level, meat, fish, and eggs have high cholesterol. Their wide-scale consumption has contributed to the dramatic increase in the number of premature deaths from heart disease, strokes and cancer; and meat-based diets contribute to a host of other health-related problems.

In contrast, a plant-based diet is generally low in fat, including saturated fat, which can help reduce blood cholesterol levels and the risk for heart disease. Flesh foods, on the other hand, are high in saturated fat, which is the biggest contributor to blood clotting, which can result in heart disease and stroke.

And, plant-based proteins have zero cholesterol. High cholesterol is one of the major risk factors for developing heart disease. Meat is high in LDL (bad cholesterol) and the more LDL you have in your bloodstream, the more likely plaque (atherosclerosis) will form in your arteries.

A meat-based diet is an extremely wasteful use of the earth's limited resources, as it requires many times more resources to create a pound of animal flesh than a pound of vegetarian foods. Whether it's unchecked air or water pollution, soil erosion, or the overuse of resources, raising animals for food is wreaking havoc on the Earth.

And finally, from an ethical point of view, eating animals causes extreme pain and suffering to billions of innocent creatures. Given the suffering these animals endure, and given that all our nutritional needs can easily be satisfied without eating these animals, vegetarianism is morally required. The fact is that eating animals is unnecessary because nature has provided ample vegetables, fruits, grains, legumes and dairy products for human sustenance. Therefore, the slaughter of animals for food is a luxury rather than a necessity and is morally wrong

The single most important thing you can do for your health, the environment, and the innocent animals is to adopt a vegetarian diet.
