All about fruitarianism with a long-term fruitarian, Lena

Recommended intake for adults, in milligrams per day (recommended calcium allowances based on North American and western European data):

  • Adolescents, 10–18 years - 1300 mg / day
  • Females, 19 years to menopause - 1000 mg / day
  • Females, pregnant women (last trimester) - 1200 mg / day
  • Females, lactating women - 1000 mg / day
  • Females, postmenopause - 1300 mg / day
  • Males, 19–65 years - 1000 mg / day
  • Males, 65+ years - 1300 mg / day

The calcium requirement of an adult is generally recognized to be the intake required to maintain calcium balance and therefore skeletal integrity

Calcium balance is determined by the relationship between calcium intake and calcium absorption and excretion. Relatively small changes in calcium absorption and excretion can neutralize a high intake or compensate for a low one. 

A positive calcium balance (net calcium retention) is required throughout growth, particularly during the first 2 years of life and during puberty and adolescence. These age groups therefore constitute populations at risk for calcium deficiency, as do pregnant women (especially in the last trimester), lactating women, postmenopausal women, and, possibly, elderly men. 

Dalai Lama

Life is as dear to a mute creature as it is to a man. Just as one wants happiness and fears pain, just as one wants to live and not to die, so do other creatures.

Genetics

Genetics is the study of genes, genetic variation, and heredity in living organisms. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. 

The Human Genome Project has estimated that humans have 20,000 - 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but less than 1% of genes are slightly different between people. Poplar tree genome suggests more than 45,000 genes.
