Vegetarian diets in childhood and adolescence
AbstractIn Western countries, vegetarian diets are associated with lower intakes of energy, saturated fatty acids and animal protein and higher intakes of fibre and phytochemicals, compared to omnivorous diets. Whether the corresponding health benefits in vegetarians outweigh the risks of nutrient deficiencies has not been fully clarified. It should be noted that vegetarians often have a higher socioeconomic status, follow a more health-conscious lifestyle with higher physical activity, and refrain from smoking more often than non-vegetarians. The nutritional needs of growing children and adolescents can generally be met through a balanced, vegetable-based diet; however, due to their higher nutrient requirements per kilogramme of body weight, vegetarian children have a higher risk for developing nutrient deficiencies than adults. With a vegetarian diet, the mean intakes of some nutrients, such as the omega-3 fatty acid docosahexaenoic acid (DHA), are lower than in omnivores or those eating fish. For other nutrients, such as iron and zinc, the bioavailability from vegetable foodstuffs is reduced when the intake of phytates and fibre is high; thus, the prevalence of iron deficiency can be increased despite high vitamin C intake. In addition, vitamin B12 is only found in animal-source foods. Vitamin B12 should be supplemented in people of all age groups who follow a strict vegan diet without consuming animal products. A vegetarian diet in childhood and adolescence requires good ...
In conclusion, clinical characteristics of vitamin B12 deficiency are broad and nonspecific and may not be associated with anemia and increased mean corpuscular volume. Since different clinical characteristics can be seen without anemia, awareness and cautious approach are essential in order to avoid severe clinical disease, especially in children from underdeveloped countries.

This study assessed whether all BMS patients with ID (so-called ID/BMS patients) had iron deficiency anemia (IDA) and evaluated whether the ID/BMS patients had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than healthy control subjects.Materials and methodsThe blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 143 ID/BMS patients and 442 healthy control subjects were measured and compared.ResultsWe found that 143 ID/BMS patients had significantly lower mean blood Hb and serum i...
VITAMIN B12 is one of the main "raw materials" needed to build the healthy red blood cell; the other is folate or folic acid. In order to make healthy red blood cells that can carry oxygen around the body a person needs adequate levels of B12. Feeling this sensation in your chest is a warning sign of pernicious anaemia.
Good sources of vitamin B12 include low-fat milk, poultry, eggs and fish. → Support PsyBlog for just $4 per month.

VITAMIN B12 is an essential nutrient that a person ’s body need to perform its vital functions. If left untreated, a vitamin B12 deficiency can cause various health complications and if your skin looks this colour it could be a warning.

This recessive disorder is characterized by a failure to metabolize cobalamin into adenosyl- and methylcobalamin, which results in the biochemical perturbations of methylmalonic acidemia, hyperhomocysteinemia, and hypomethioninemia caused by impaired activity of the downstream enzy...
VITAMIN B12 helps the body to perform a number of vital functions so lacking the vitamin can cause a range of noticeable symptoms. The symptoms usually develop gradually, but can worsen if the condition goes untreated.
VITAMIN B12 helps the body to perform a number of vital functions so lacking the vitamin can cause a host of unsettling symptoms. Experiencing a certain sensation in your hands may signal you are lacking the vitamin.
VITAMIN B12 plays an essential role in one ’s overall health. The vitamin is essential in the production of red blood cells and DNA, as well as proper functioning of the nervous system. When the body lacks the vitamin a variety of symptoms can be triggered, including one on a person's tongue.
