All about fruitarianism with a long-term fruitarian, Lena

I composed two lists with a few examples of the fruitarian food sources of zinc: fruits, seeds, seaweeds and mushrooms. You can compare the amounts of zinc in them with the recommended daily allowance of the mineral. RDA is usually around 20% higher than the amount needed for half of the healthy people. 

The RDA (recommended dietary allowance) of zinc for healthy adult women and men is 8 mg a day and 11 mg a day, respectively. 

Examples of high in zinc plant food sources, fruits and seeds: 

  • Sesame seeds, whole, dried (~ 8 mg /100 g or ~ 1/5 of a pound, lb)
  • Pumpkin and squash seeds, dried - pepitas (~ 7 mg /100 g)
  • Pine seeds (~ 6 mg / 100 g) 
  • Sunflower seeds (~ 5 mg /100 g)
  • Tomatoes, sun-dried (~ 2 mg in 100 g)
  • Lentils, sprouted (~ 2 mg in 100 g)
  • Almonds (~ 1 mg zinc in about 25 whole almonds)
  • Green peas, fresh or unfrozen (~ 1 mg zinc in 1 cup)
  • Avocados (~ 1 mg zinc in one bigger fruit)
  • Blackberries (~ 0.8 mg zinc in one cup - 150 g)

Other fruitarian foods high in zinc, algae and mushrooms:

  • Seaweed agar, dried (~ 6 mg zinc in 100 g)
  • Seaweed, spirulina, dried (~ 2 mg zinc in 100 g)
  • Seaweed kelp, raw (~ 1 mg in 100 g)
  • Mushrooms, shiitake (~ 1 mg in 100 g)

Charles Darwin

There is no fundamental difference between man and the higher animals in their mental faculties . . . The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery.

Vitamin A

Retinoids retinol, retinal, and retinoic acid - 3 active forms of vitamin A - "preformed" vitamin A.

Beta carotene can easily be converted to vitamin A by the human body. 

Large amounts of supplemental vitamin A (but not beta carotene) can be harmful to bones.

Vitamin A keeps tissues and skin healthy, plays an important role in bone growth. Diets rich in the carotenoids alpha carotene and lycopene seem to lower lung cancer risk. Carotenoids act as antioxidants. Foods rich in the carotenoids lutein and zeaxanthin may protect against cataracts. Essential for vision lycopene may lower prostate cancer risk.

Recommended daily amount: 700 mcg - 900 mcg or 3 mg - 6 mg beta-carotene (~ 1 cup of raw cantaloupe or sweet red peppers, or 2 mangoes, or 1/5 of one baked sweet potato). 

Because the body converts all dietary sources of vitamin A into retinol, 1 mcg of physiologically available retinol is equivalent to the following amounts from dietary sources: 1 mcg of retinol, 12 mcg of beta-carotene, and 24 mcg of alpha-carotene or beta-cryptoxanthin. From dietary supplements, the body converts 2 mcg of beta-carotene to 1 mcg of retinol.
