B-12 and Veganism – Flashback Friday

IMG_0468There are many vitamins and minerals that we hear about in the media, from medical professionals, and from our parents/family growing up. We mostly understand that we require some calcium, vitamin D, vitamin C, and iron. We understand that we need protein (though there are very interesting debates about how much). However, many of us have no clue about the B vitamins. Vitamin B12 can be a particular issue for those on a vegan diet who do not consume fortified food/drink (like soymilk). Thus, raw vegans may be more inclined to a B12 deficiency.

Why is this important? B12 is a vitamin that the body requires (like folic acid) to make red blood cells. The body cannot synthesize B12; it must be consumed in the diet. I’m sure that I don’t need to explain that red blood cells are pretty important to our oxygenation and thus our overall health and wellness.

In a typical Westernized diet, people generally absorb sufficient quantities of B12 by eating meat, eggs, and dairy products. Those who consume a vegan diet, or those who eat a very limited variety of foods (which can be more common in older adults), may find it very difficult to consume adequate B12. Additionally, some medical conditions (including Crohn’s disease) and medications (including popular stomach acid reducers) may make it hard for the body to absorb enough B12 through diet.

Often, people are unaware that they have a B12 deficiency unless/until it becomes severe.  Symptoms can include fatigue, bleeding gums, weight loss, dizziness. Persistent B12 deficiency can even lead to nerve damage and the associated physical and mental symptoms.

If you suspect that you have a B12 problem, your physician can test for anemia and B12 levels. However, even if you don’t think testing is needed, it’s probably a good idea to think about how much B12 you are consuming and whether you need to supplement your dietary levels. For those on a vegan, but not raw, diet, soy milk and other processed vegan foods may be fortified with B12. For individuals on a raw diet, B12 (or full spectrum B) vitamins are readily available in most pharmacies, GNC stores, or online.

In Praise of the B Vitamins

My son, Devin, is home from college this week on spring break and has been singing the praises of the B vitamins to anyone who will listen, and maybe some people who won’t.  So, I thought I would take the time to discuss the Bs here on TheVeganAsana, in his honor.

The B-complex vitamins are actually a group of eight vitamins, which include:

  • thiamine (B1)
  • riboflavin (B2)
  • niacin (B3)
  • pantothenic acid (B5)
  • pyridoxine (B6)
  • biotin (B7)
  • folic acid (B9)
  • cyanocobalamin (B12)

Each of the B vitamins has different impacts on the body, though connections can be seen.

Thiamine impacts the bodies energy production as well as several enzymes related to muscle (including the heart) function and the nervous system.  It’s unusual to have a thiamine deficiency, unless an individual consumed excess alcohol, because alcohol interferes with thiamine absorption.  The most dramatic result of thiamine deficiency is beriberi, a disease that creates anemia, muscle spasms/weakness/atrophy, and even paralysis. Other conditions related to lack of thiamine cause problems with short-term memory and coordination.  In less serious effects, small thiamine deficiencies can create sensitive teeth and gums, and lip dryness and cracking. Thiamine can be found in many whole grains, potatoes, pork, seafood, liver, green leafy vegetables, sweet corn, berries, yeast, and kidney beans.

Riboflavin helps the body produce energy and affect enzymes that influence the muscles, nerves, and heart. Deficiencies of t his vitamin can create dermatitis, swelling around the mouth and nose tissues, light sensitivity, lesions in the corners of the lips, tongue inflammation, and anemia. B2 is found in cereals and whole grains, enriched bread, dairy products, eggs, peas, liver, and green leafy vegetables.

Niacin has a role in energy production in cells and helps keep the skin, nervous system, and digestive system healthy. Niacin deficits can be related to the disease pellegra, which causes digestive issues, skin and mouth problems, dementia, and can be fatal.  B3 is found in liver, fish, chicken, lean red meat, nuts, brewer’s yeast, peanuts, potatoes, whole grains, and dried beans.

Pantothenic acid influences normal growth and development.  In developing children, these issues may be impacted by deficiency, but little other effect has been shown.  The vitamin is found in abundance in meats, legumes and whole-grain cereals.

Pyridoxine, better known as B6, helps the body break down protein and helps maintain the health of red blood cells, the nervous system, and parts of the immune system. Most people in the United States take in adequate B6, but lack of this vitamin can create skin problems, swelling of the tongue, anemia, nervous system abnormalities, insomnia, poor coordination, and even mental issues when severe enough. Pyridoxine is found in many foods, including liver and other organ meats, fish, dairy products, wheat germ, whole grains, soybeans, squash, peppers, turnip greens, avocado, sunflower seeds, and walnuts.

Biotin helps break down protein and carbohydrates and helps the body make hormones. Biotin deficiencies are rare, but may cause dermatitis.  Biotin is made by intestinal bacteria and is also in peanuts, liver, egg yolks (interestingly, eating too many egg whites can actually inhibit the ability to use B7 effectively), bananas, mushrooms, watermelon, brewer’s yeast, peanuts, cauliflower, mushrooms, and grapefruit.

Folic acid assists the body in the creation and maintenance of DNA material and is active in the production of red blood cells.  Some increased cancer risk has been seen with low levels of folic acid, and folic acid deficiencies are correlated with anemia, mouth irritation, and poor growth in children.  Folic acid is present in many foods, but can be weakened in cooking.  Sources for folic acid include yeast, green leafy vegetables, liver, citrus fruits, mushrooms, nuts, peas, dried beans, and wheat bread.

Cyanocobalamin, better known as B12, plays a role in the body’s growth and development. It also has a part in producing blood cells, nervous system function, and how the body uses folic acid and carbohydrates.  As I have covered in more depth here, B12 deficiency can have many symptoms including is exhaustion and weakness, loss of appetite and weight loss, anemia, sores of the mouth and tongue, and even mental issues such as depression, confusion, poor memory, and dementia. In children, B12 lack can additionally create failure to thrive and developmental delays.  Because medical conditions, medications, and aging can impact the ability to process B12, and it is largely found in animal products, supplementation is frequently necessary. found in eggs, meat, poultry, shellfish, milk, and milk products.

So, eat your fruits and veggies, supplement where needed, and B the best you can B.

Vitamin B12 Deficiency in the Vegan/Raw Diet
