Dear Team Endunamoo,
My 16 year old daughter has decided to try a vegetarian diet, she's not heavy set and I was just wondering what the risks or benefits are of this diet style?
Anon.
I think first i should cover the benefits of being vegitarian because the negatives will be a longer list. A clinical research team decided to see the benefits of a vegetarian diet [high in antioxidants and fibrous plants and fruits] compared to omnivores or the general public. The research suggested that vegitarians had low oxidative stress [low mitochondrial damage due to antioxidants] reduced bodyweight, reduced bodyfat, and lower cholesterol levels; in other words overall lower lipid levels [1] It would be important to point out that some of the overall mass loss would be in the muscle, probably by a negative nitrogen balance [low protein leads to negative nitrogen balance and the body will "eat" muscle to retain at least a neutral balance].
Negatives:
Where to begin, where to begin? We'll go from the head to the toes of the human anatomy and the damage that can occure. First issue would be the mental status of an individual. One research study suggests that women who go vegetarian are more likely to experience eating disorder because they now have an excuse to not eat certain foods [2]. Heavy Vegan or strict vegetarian diets can result in Vitamin and mineral defficiency [3]. One study found that vegetarians compared to the general population were more likely to suffer from mental disorders such as: Depression, anorexia, anxiety disorders and somatoform disorders. [4] Vegetarians are more likely to be Vitamin B12 defficient and suffer from impaired atriel endothelial funtion and without propper supplementation be at risk for artherosclerosis.[5] Don't forget there will probably be muscle wasting due to decreased protein synthesis and a negative nitrogen balance.
So remember kids eat your veggies but you better have a giant steak sitting right next to it.
