United Nations report 2010: A global shift towards a vegan diet is vital to save the world from hunger, fuel poverty, and the worst impacts of climate change.
Impacts from agriculture are expected to increase substantially due to population growth increasing consumption of animal products. Unlike fossil fuels, it is difficult to look for alternatives: people have to eat. A substantial reduction of impacts would only be possible with a substantial worldwide diet change, away from animal products.
Vitamins are a group of substances that are needed for normal cell function, growth, and development. There are 13 essential vitamins:
- Vitamin A (retinol, retinal, 4 carotenoids)
- Vitamin C (ascorbic acid)
- Vitamin D (D3 - Cholecalciferol, D2 - Ergocalciferol)
- Vitamin E (tocopherols, tocotrienols)
- Vitamin K (phylloquinone, menaquinones)
- Vitamin B1 (thiamine)
- Vitamin B2 (riboflavin)
- Vitamin B3 (niacin)
- Vitamin B5 (pantothenic acid)
- Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine)
- Vitamin B7 (biotin)
- Vitamin B9 (folic acid)
- Vitamin B12 (cyanocobalamin)
Fat-soluble vitamins are stored in the body's fatty tissue: vitamins A, D, E, K.
Water-soluble vitamins - the body must use almost all water-soluble vitamins right away - vitamins B1, B2, B3, B5, B6, B7, B9 and C.
Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.
