All about fruitarianism with a long-term fruitarian, Lena

Vegan

Vegan diet (or strict vegetarian diet) excludes all animal products - meat, eggs, dairy products, etc.

  • Response to Liberation Pledge

    I learned about this DxE pledge on the great channel ModVegan, and commented: 

    Margaret, this is the first time I hear about this Liberation Pledge (thank you), and I am completely against it.

    Positive pear-pressure? They are calling for acts of public disrespect to the participants' closest people! The first result will be alienation of these people from their loved ones, colleagues, and clients, and in deep personal problems.

    Your alternative is much better, but every vegan would act this way in most situations anyway. I am a long-term vegan, BTW. 

  • Satisfying Fruitarian Food Days

    Here are two examples of two random satisfying days of vegan fruitarian food for one female and one male persons.

    How is your "perfect" day of food looks like? 

    Yesterday was one of mine (Fruitarian Lena):

    • two glasses of freshly made organic orange juice,
    • a great smoothie with strawberries, purple grapes, bananas and oranges,
    • ~50 g of organic raw zucchini chips (with sesame and sunflower seeds),
    • a few dehydrated tomatoes,
    • tried 4-5 pea sprouts for the first time,
    • a big bowl of organic blueberries and blackberries,
    • a pound pack (1/2 kg) of very ripe dark red organic strawberries!
  • Nori and Chlorella for B12

    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.

  • Vegetarian Diets and Health

    Vegetarian diets do not contain meat, poultry or fish, vegan diets further exclude dairy products and eggs. Vegetarian and vegan diets can vary widely.

    In general, vegetarian diets provide relatively large amounts of cereals, pulses, nuts, fruits and vegetables.

    In terms of nutrients, vegetarian diets are usually

    • rich in carbohydrates, n-6 fatty acids, dietary fibre, carotenoids, folic acid, vitamin C, vitamin E and Mg,
    • relatively low in protein, saturated fat, long-chain n-3 fatty acids, retinol, vitamin B12, zinc (Zn),
    • vegans may have particularly low intakes of vitamin B12 and low intakes of Ca.

    On average, vegetarians and vegans have a relatively low BMI and a low plasma cholesterol concentration, but higher plasma homocysteine concentrations than in non-vegetarians. Overall, the data suggest that the health of Western vegetarians is good and similar to that of comparable non-vegetarians.

  • Vegetarian Diets and Heart Disease

    In comparison with regular meat eaters, mortality from ischemic heart disease was

    • 20% lower in occasional meat eaters,
    • 34% lower in people who ate fish but not meat,
    • 34% lower in lacto-ovo-vegetarians,
    • 26% lower in vegans.

    There were no significant differences between vegetarians and non-vegetarians in mortality from the other causes of death examined.

  • Vegan Diet Protects from Cancer

    Vegan diets showed statistically significant protection for overall cancer in both genders combined, and for female-specific cancers.

  • Toxic Acrylamide in Cooked Plant Foods

    In 2010, the Joint Food and Agriculture Organization / World Health Organization Expert Committee on Food Additives (JECFA) concluded that acrylamide is a human health concern. Certain doses of acrylamide are toxic to animals and humans.

    Although acrylamide has known toxic effects on the nervous system and on fertility, the 2002 report by the Food and Agriculture Organization of the United Nations and the World Health Organization (WHO) concluded the intake level required to observe neuropathy (0.5 mg/kg body weight/day) was 500 times higher than the average dietary intake of acrylamide (1 μg/kg body weight/day). For effects on fertility, the level is 2,000 times higher than the average intake.

    Acrylamide is a neurotoxin by either oral (in animals) or inhalation exposure (in humans and in animals). Toxic effects are central and peripheral neuropathy causing drowsiness, hallucinations, distal numbness, and ataxia. Recovery is possible after cessation of exposure. 

    Acrylamide is typically found in plant-based foods cooked with high heat (e.g., frying, roasting, and baking), not raw plant-based foods or foods cooked by steaming or boiling (below 120 degrees Celsius / 248 Fahrenheit). Potato chips and French fries were found to contain higher levels of acrylamide compared with other foods.

    The European Chemical Agency added acrylamide to the list of substances of very high concern in March 2010.

    Acrylamide is known to causecancer in animals. It is not clear, as of 2016, whether acrylamide consumption increases people's risk of developing cancer. 

  • Calcium Rich Fruits and Seeds

    Recommended intake of calcium for adults 19–50 years, in milligrams per day (RDA, recommended dietary allowances based on North American and western European data) is  1000 mga day (1 g).

    Example of calcium plant food sources, fruit and seeds: 

    • Sesame seeds, whole, roasted - 989 mg calcium / 100 g.
    • Chia seeds, dried - 631 mg calcium / 100 g. 
    • Figs, dried - 162 mg calcium / 100 g, ~ 600 g figs for 1000 mg (1 g) calcium
    • Olives, ripe, canned - 94 mg calcium / 100 g.
    • Dates, medjool - 64 mg calcium / 100 g.

  • Nori is the Best Known Seaweed Source of B12

    Vitamin B(12) concentrations of dried green (Enteromorpha sp.) and purple (Porphyra sp.) lavers nori were determined, in micrograms: 

    • green nori: 64 - 69 mcg per 100 g of dry weight,
    • purple nori: 32 - 25 mcg per 100 g of dry weight.

    Non-coenzyme forms (hydroxo and cyano forms) of vitamin B12 predominate in both. 

    Recommended dietary amounts (RDAs) for cobalamin, B12, are 2.4 mcg (micrograms) daily, one can cover it with 4 g of dry green nori. 

    The dried lavers contained lesser amounts of dietary iodine (~ 4-6 mg per 100 g of dry weight) relative to other seaweeds, suggesting that excessive intake of the dried lavers is unlikely to result in harmful intake of iodine.

    These results indicate that the nori are the best source of vitamin B12 among edible seaweeds, especially for strict vegetarians (vegans).

  • Tarahumara Runners on Corn and Beans Diet

    The Rarámuri or Tarahumara are a Native American people of northwestern Mexico who are renowned for their long-distance running ability. Rarámuri, means "runners on foot" or "those who run fast". Staple crops are corn and beans.

    Frugan (fruitarian) runners Tarahumara were described by Ruth Heidrich, Ph.D., a runner for 36 years and vegan for 21 years, who won over 800 age-group first place trophies in runs, triathlons, biathlons, and track and field, and completed the Ironman Triathlon 6 times, run 67 marathons, and holds a number of fitness records, following a diet similar to the Tarahumara:

    "...Their only food is tesguino, milled corn mixed with water to a drinkable consistency. This is the mainstay (75%) of Tarahumara diet, with the remaining food being beans and squash. They also take the milled corn as their sole food when traveling, since it is lightweight, doesn't spoil, and is easily prepared by mixing it with water in a half gourd they carry with them. This gives them great stamina and, more importantly, none of them appeared to be protein or calcium deficient with this plant-based diet."

    The Tarahumara runners are legendary for their 24-, 36-, even 72-hour long runs. In the Leadville 100-miler in 1991, the Tarahumara took first, second, and fourth places.

Man, do not pride yourself on superiority to animals.

Estimated Average Requirement EAR

Estimated Average Requirement (EAR) is the average daily nutrient intake level that is estimated to meet the requirements of half  - 50% - of the healthy individuals in a particular life stage and gender group. 

Because the needs of the other half of the population will not be met by this amount, the EAR is increased by about 20% to arrive at the RDA.

Before setting the EAR, a specific criterion of adequacy is selected, based on a careful review of the literature. When selecting the criterion, reduction of disease risk is considered along with many other health parameters.
