All about fruitarianism with a long-term fruitarian, Lena

A nutritional analysis for the dietary food intake and serum vitamin B12 (cobalamin) level of a group of 6 vegan children aged 7 to 14 who had been living on a vegan diet for 4 to 10 years suggests that consumption of nori may keep vegans from suffering vitamin B12 deficiency.

Rauma et al. also reported that vegans consuming nori and/or chlorella had a serum vitamin B12 concentration twice as high as those not consuming these algae.

Percy Bysshe Shelley

They are called into existence by human artifice that they may drag out a short and miserable existence of slavery and disease, that their bodies may be mutilated, their social feelings outraged. It were much better that a sentient being should never have existed, than that it should have existed only to endure unmitigated misery.

Nutrients

Nutrient - a substance that provides essential nourishment for growth and the maintenance of life. 

Foods are composed chiefly of carbohydrates, fats, proteins, water, vitamins, and minerals. Carbohydrates, fats, proteins, and water represent virtually all the weight of food. Carbohydrates, fats, and proteins comprise 90% of the dry weight of foods.
