All about fruitarianism with a long-term fruitarian, Lena

Nutrients

Nutrients are component in foods that an organism uses for maintenance and growth.

  • B12 Supplementation Effective Sublingually and Orally

    A dose of 500 µg of cobalamin given either sublingually or orally is effective in correcting cobalamin deficiency

  • Vitamin B12 Deficiency as a Worldwide Problem

    Pernicious anemia is a common cause of megaloblastic anemia throughout the world and especially in persons of European or African descent. Dietary deficiency of vitamin B12 due to vegetarianism is increasing and causes hyperhomocysteinemia.

    The breast-fed infant of a vitamin B12–deficient mother is at risk for severe developmental abnormalities, growth failure, and anemia. Elevated methylmalonic acid and/or total homocysteine are sensitive indicators of vitamin B12–deficient diets and correlate with clinical abnormalities.

    Dietary vitamin B12 deficiency is a severe problem in the Indian subcontinent, Mexico, Central and South America, and selected areas in Africa. Dietary vitamin B12 deficiency is not prevalent in Asia, except in vegetarians. Areas for research include intermittent vitamin B12 supplement dosing and better measurements of the bioavailability of B12 in fermented vegetarian foods and algae.

  • B12 May Be Synthesized by Small Intestine Microflora

    In man, physiological amounts of vitamin are absorbed by the intrinsic factor mediated mechanism exclusively in the ileum, the third portion of the small intestine. Human faeces contain appreciable quantities of vitamin B12 or vitamin B12-like material presumably produced by bacteria in the colon, but this is unavailable to the non-coprophagic individual. However, the human small intestine also often harbours a considerable microflora and this is even more extensive in apparently healthy southern Indian subjects. We now show that at least two groups of organisms in the small bowel, Pseudomonas and Klebsiella sp., may synthesise significant amounts of the vitamin.

  • Lean Meat is Not Pure Protein

    "Lean meat" is a misleading term. I noticed many times in conversations that people who think that they eat "proteins" tend to think about this food group as an almost pure protein, a perfect set of essential amino acids. Especially if they consume so called "lean meats." 

    In beef (presented as "90% lean meat") - half of the calories are from fat (http://nutritiondata.self.com/facts/beef-products/6193/2). Even in the leanest bird meat approximately the fifth of the energy is from fat, ~18% in the leanest I could find (http://nutritiondata.self.com/facts/poultry-products/704/2).

    Digestibility-corrected amino acid score (PDCAAS) of protein in beef is only 0.92, chicken - 0.91(?), and egg whites and soy - 1 or 100% (not that it matters much). Note, that 62% of calories in a whole egg are from fat, and 40% in soybeans. 

  • Sugars Can Be Turned into Fat

    When we are eating excess amounts of carbohydrates (sugars), liver converts the carbon compounds from sugar into fatty acid, and then fat.

    If we continue to consume too much of sugars, complex or simple, and to accumulate fat, especially in the waist area, we can develop insulin resistance.

  • High-Fat Diets and Obecity

    High-fat diets and low physical activity levels may accentuate the susceptibility to obesity by the FTO variant. The fat mass and obesity-associated gene (FTO) has been shown to be associated with obesity and to influence appetite regulation.

Ethics and Aesthetics

Ethics - moral principles that govern behavior of a person or a group.

Ethics can refer to standards of right and wrong that prescribe what a human ought to do. Ethical standards include standards relating to rights (e.g. right to life, the right to freedom from injury).

Laws, and social norms, or feelings can differ from what is ethical. It is necessary for individuals to frequently examine own standards to ensure that they are reasonable. 

Ethics as moral philosophy involves systematizing, defending, and recommending concepts of right and wrong conduct. Moral philosophy is related to the fields of moral psychology, descriptive ethics, and value theory.

As a branch of philosophy, ethics investigates the questions

  • "What is the best way for people to live?
  • "What actions are right or wrong in particular circumstances?"

Axiology is the philosophical study of value, collective term for ethics and aesthetics - philosophical fields that depend crucially on notions of worth. 

Aesthetics studies the concepts of "beauty" and "harmony." Aesthetics (esthetics) is a branch of philosophy dealing with the nature of art, beauty, and taste, creation and appreciation of beauty. It is more scientifically defined as the study of sensori-emotional values. More broadly, aesthetics is defined as "critical reflection on art, culture and nature."
