  • Same Food Every Day

    For days I had the same: oranges, and then tomatoes with avocado, with occasional grapes or apples. It is around 6-8 pounds or ~ 3-4 kg (bulk), $5-7 a day, buying smartly in California.

    What are you guys having these days?

  • Tired and Happy - 20 Years Vegetarian

    On this gray Sunday, April 14 2013, I like to celebrate my 20-year strict high fruit vegetarianism. I switched some time in the beginning of March 1993 (do not remember the exact date, my notebooks were destroyed), but by now, on  it must be well over 20 years.

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.
