  • Vitamin C

    Vitamin C, or L-ascorbic acid, or ascorbate, is an essential nutrient for humans, a water-soluble vitamin. Humans, unlike most animals, are unable to synthesize vitamin C, so it is an essential dietary component. 

    • Vitamin C is required for the biosynthesis of collagen (an essential component of connective tissue), L-carnitine, and certain neurotransmitters, it is also involved in protein metabolism.
    • Vitamin C is also an important physiological antioxidant and has been shown to regenerate other antioxidants within the body, including alpha-tocopherol (vitamin E). Vitamin C regenerates vitamin E by reducing vitamin E radicals formed when vitamin E scavenges the oxygen radicals. 
    • Vitamin C plays an important role in immune function and improves the absorption of nonheme iron, the form of iron present in plant-based foods.

    Approximately 70%–90% of vitamin C is absorbed at moderate intakes of 30–180 mg a day. At doses above 1 g a day, absorption falls to less than 50% and absorbed, unmetabolized ascorbic acid is excreted in the urine. 

    Insufficient vitamin C intake causes scurvy, which is characterized by fatigue or lassitude, connective tissue weakness, and capillary fragility.

    Cells accumulate vitamin C. The total body content of vitamin C ranges from 300 mg (at near scurvy) to about 2 g.

    • High levels of vitamin C are maintained in cells and tissues, and are highest in leukocytes (white blood cells), eyes, adrenal glands, pituitary gland, and brain.
    • Relatively low levels of vitamin C are found in extracellular fluids, such as plasma, red blood cells, and saliva.
  • All Known Essential Vitamins

    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.

Erich Fromm

It is naively assumed that the fact that the majority of people share certain ideas and feelings proves the validity of these ideas and feelings. Nothing could be further from the truth. Consensual validation as such has no bearing on reason or mental health.

Veganism

Veganism is the practice of abstaining from the use of animal products, particularly in diet, and an associated rejection of the commodity status of animals. A follower of either the diet or the philosophy is known as a vegan.

Dietary vegans refrain from eating animal products, not only meat but also egg and dairy products and other animal-derived products. The term "ethical vegan" is often applied to those who extend the philosophy beyond diet into other areas of their lives. Environmental veganism refers to avoiding animal products on the premise that harvesting or industrial farming of animals is environmentally damaging and unsustainable.

The term vegan was coined in 1944 by Donald Watson when he co-founded the Vegan Society in England. At first this meant "non-dairy vegetarian" and later that one "should live without exploiting animals".
