The final date I will remember they taking place is Mr. Rogers several years before. But just as Mr. Rogers is, no light hearted matter, one of the most very important members of my personal very early young people, becoming my television next-door neighbor and all sorts of, Kurt Vonnegut, just who I simply read is actually deceased within 84, try perhaps one of the most important folks of my personal puberty.

Vitamin Ba dozen (cobalamin) is receiving much attention these days. Vitamin B12 is one of the B vitamins implicated in brain and heart health, and it is one of the vitamins most likely to be deficient in the diets of vegetarians and vegans.
The consequences of vitamin B12 deficiency are profound. During pregnancy, a deficiency of B12 increases the risk of preeclampsia, a serious pregnancy complication characterized by high blood pressure and organ damage. A prenatal deficiency of B12 and/or folate (vitamin B9) also increases the infant’s risk of neural tube defects (defects of the brain and spine, such as spina bifida). In adults, B12 deficiency increases the risk of peripheral neuropathy, depression, osteoporosis, Alzheimer’s disease, heart disease, and stroke. ,, Sadly, B12 deficiency may even negate the cardiovascular benefits of a vegetarian diet.
Vitamin B12 is found in significant quantities only in animal foods. It is synthesized by microbes, including the bacteria that live in the rumens (first stomachs) of cows. This explains why B12 is found in significant amounts in meat and dairy products. Fish acquire vitamin B12 by consuming phytoplankton, which have a symbiotic relationship with bacteria that produce B12. Plants, on the other hand, do not make B12 and do not require it for growth. This simple fact of nature makes B12 a nutrient of concern for vegetarians and especially for vegans, who avoid consuming meat, dairy products, or fish.
As more people turn to plant-based diets for many reasons, including overall health, nutritionists are raising the alarm about the risks of B12 deficiency. “Of all the micronutrients, B12 is the one we’re most concerned about,” says Thomas Sanders, professor emeritus of nutrition at King’s College London.
