All about fruitarianism with a long-term fruitarian, Lena

Because the system for disposal of excess nitrogen is efficient, protein intakes moderately above requirement are believed to be safe.

Brenner et al. (1982) postulated that excess protein intake accelerates the processes that lead to renal glomerular sclerosis, a common phenomenon of aging. There is supportive evidence from studies in animals, but not in humans on this point. Urinary calcium excretion increases with increased protein intake if phosphorus intake is constant. If phosphorus intake increases with protein intake, as it does in U.S. diets, the effect of protein is minimized.

Habitual intakes of protein in the United States are substantially above the requirement, and although there is no firm evidence that these intake levels are harmful, it has been deemed prudent to maintain an upper bound of no more than twice the RDA for protein.

Vitamin B1 Thiamine

Vitamin B1 (Thiamin, Thiamine) is one of 8 B vitamins, the first B vitamin discovered. All B vitamins help the body convert carbohydrates into glucose, which the body uses to produce energy, B-complex vitamins also help the body metabolize fats and protein. All B vitamins are water soluble.

All living organisms use thiamine, but it is synthesized only in bacteria, fungi, and plants. Animals must obtain it from their diet, therefore for humans it is an essential nutrient.  Your body needs it to form adenosine triphosphate (ATP), which every cell of the body uses for energy.

B1 helps convert food into energy, needed for healthy skin, hair, muscles, and brain. 

Thiamine deficiency has a potentially fatal outcome if it remains untreated. In less-severe cases, nonspecific signs include malaise, weight loss, irritability and confusion.

Recommended daily amount: 1.1 - 1.2 mg (~ 50 g of flaxseeds, or sesame tahini, or 100 g pine or sunflower seeds, or corn flour).
