Adopting a vegetarian diet can be a fantastic entry into experiencing better health. A vegetarian diet is associated with a higher consumption of fiber, folic acid, vitamins C and E, magnesium, unsaturated fat. This often results in vegetarians having lower cholesterol, being thinner, having lower blood pressure, and reduced risk of heart disease.

1. Mood Improve

Arachidonic acid is a substance that usually comes from dietary animal sources and, no surprise, vegetarian diets are not high in arachidonic acid. This can be beneficial, as research has shown a link between arachidonic acid and mood disturbances. Researchers at Benedictine University performed a study to investigate the impact of restricting animal products and mood and confirmed that mood improvements do happen when eating meat, fish, and poultry are restricted. 

Additionally, Croatia’s Institute for Medical Research and Occupational Health conducted mental health surveys amongst vegetarians and found them to have lower levels of neuroticism. 

2. Reduce Incidence of Diabetes

According to Loma Linda University School of Public Health, vegetarian diets are associated with a significant reduction in the incidence of diabetes.  Information published by George Washington University School of Medicine has also confirmed that vegetarian diets offer an important benefit for the management of diabetes and can even reduce the likelihood of development by one half.

3. Reduces Risk of Cataract Development

Oddly enough, research released by the Nuffield Department of Clinical Medicine at the University of Oxford has shown a strong relation between the risk of developing cataracts and diet; with a higher risk falling on meat eaters and the lowest risk groups being vegetarians and vegans. 

4. Reduces Risk of Cardiovascular Disease

According to the JCU University Skin Cancer Research Clinic, there is a relationship between a vegetarian diet and decreased risk of cardiovascular disease. Why? Most vegetarian diets are full of antioxidant rich foods. Antioxidants are molecules that can reduce the damage caused by oxidative stress, including atherosclerosis

5. Less Chance of Developing Kidney Stones

New York University Langone Medical Center reports that eliminating animal protein consumption in favor of vegetables will result in a higher urine pH; whereas low urine pH has been associated with stone formation

6. Less Risk of Stroke and Obesity

There are always exceptions but, in general, vegetarians and vegans tend to be much more deliberate in their food choices and far less likely to binge eat or choose foods based on emotions- two habits that greatly contribute to obesity. According to the University Hospital Ghent Department of Paediatrics in Belgium, following a vegetarian diet is a good way to reduce your chance at having a stroke or being obese

7. Usually Have Low Cholesterol

There’s no health benefit, at all, to eating animal fat. It should come as no surprise that when you remove it from your diet, you will also remove the detrimental effects it has on your health life. After examining the long term effects of following a vegetarian diet, Korean researchers very comfortably concluded that body fat, and cholesterol levels were lower in vegetarians than omnivores. 

8. May Improve Symptoms of Psoriasis

Psoriasis is a skin disease that causes skin redness and irritation and can be debilitating for those who suffer from it. However, according to research published by Brazil’s Universidade Federal de Pernambuco, a vegetarian diet may positively improve symptoms.

9. It Can Satisfy All Your Nutritional Requirements

If you think vegetarians and vegans are nutritionally deficient or always hungry, think again! The official position of The American Dietetic Association is that a comprehensive and well designed vegetarian, or vegan, diet can be nutritionally sound and appropriate for all ages and stages of life, including infants, the elderly, and even athletes. Good health, reduced incidence of disease, and better management of existing health problems are all associated with following a vegetarian diet

Some Another fundamental of being vegetarian.

Animal Welfare

No animal is harmed in order to feed or clothe a vegetarian. As less people eat meat, there is a reduced requirement for the farming of livestock for meat. This means less need for intensive farming methods. As more people become vegetarian, farming and the meat production industry will change.

Environmental Issues

A vegetarian lifestyle will help address some key environmental concerns. In an interview with PETA, Sir Paul McCartney says about turning vegetarian, "That is a simple but extremely effective step that many people could take to help the environment and improve their own health at the same time". Real environmental benefits can be realized by people reducing their consumption of meat or becoming a vegetarian. The GoVeg website quotes Environmental Defense that reports that "if every American skipped one meal of chicken per week and substituted vegetarian foods instead, the carbon dioxide savings would be the same as taking more than a half-million cars off U.S. roads"

Budget

A person leading a vegetarian lifestyle can spend much less than their meat eating counterparts. Vegetarian food is often cheaper, this includes both the raw ingredients purchased from supermarkets and meals taken in restaurants and other eateries. Meat makes up a significant proportion of a typical household food bill. By taking meat from the equation, a large saving can be had. Of course, replacing meat with expensive vegetarian meat substitutes may not result in quite the same saving. If a household, however, replaces meat with lentils and other low cost forms of nutritious and natural foods, a greater saving will be realized.
