German Whole Foods Vegans Consuming Nori And Mushrooms

In a 2014 study from Germany , a group of 10 whole foods vegans, who did not take supplements, were found to have MMA levels of almost 400 nmol/l . A second group of vegans who supplemented its not clear with how much but it seems to have been at least 2 doses of 1,000 µg/week of B12 on average had MMA levels of just above 200 nmol/l.

The whole foods-only vegans were given a minimum of 12 g/week of nori and 15 g/week of sun dried mushrooms, which the researchers calculated to contain an average of 3.1 µg/day of vitamin B12. Their MMA levels were measured every 2 months for 8 months and they did not dip much below 350 nmol/l.

The vegans who took supplements were given more B12 than normal , and their MMA levels steadily decreased to about 150 nmol/l at 6 months, but then back up to 200 nmol/l at 8 months.

This research indicates that at the amounts given, nori and sun dried mushrooms do not improve vitamin B12 status.

Getting An Adequate Amount Of B12

National recommendations for B12 intakes vary significantly from country to country. The US recommended intake is 2.4 micrograms a day for ordinary adults rising to 2.8 micrograms for nursing mothers. The German recommendation is 3 micrograms a day. Recommended intakes are usually based on 50% absorption, as this is typical for small amounts from foods. To meet the US and German recommendations you need to obtain sufficient B12 to absorb 1.5 micrograms per day on average. This amount should be sufficient to avoid even the initial signs of inadequate B12 intake, such as slightly elevated homocysteine and methylmalonic acid levels, in most people. Even slightly elevated homocysteine is associated with increased risk of many health problems including heart disease in adults, preeclampsia during pregnancy and neural tube defects in babies.

Achieving an adequate B12 intake is easy and there are several methods to suit individual preferences. Absorption of B12 varies from about 50%, if about 1 microgram or less is consumed, to about 0.5% for doses of 1000 micrograms or above. So the less frequently you consume B12, the higher the total amount needs to be to give the desired absorbed amount.

Should I Take Vitamin B12 Supplements

You should talk to your doctor about taking a vitamin B12 supplement if you don’t have enough B12 in your diet for example, if you are vegan or avoiding animal foods. It is very important for pregnant or breastfeeding vegan and vegetarian women to have enough vitamin B12 to reduce the risk of their baby developing a vitamin B12 deficiency.

You might also need a supplement if you can’t absorb enough vitamin B12 from food if, for example, you have a problem with your gut or an autoimmune condition. Your doctor can order a blood test to see if you have enough B12 in your body.

How B12 Works In The Body

The Harvard Medical School Special Health Report Making Sense of Vitamins and Minerals explains that vitamin B12, like all B vitamins, is water soluble, which means the body expels what it does not use. Its main job is to maintain healthy nerve cells, support proper brain function, and assist in the production of DNA and RNA. B12 also works with other B vitamins to improve certain functions. For instance, B12 and B9 together help to make red blood cells. B12, B6, and B9 team up to control blood levels of the amino acid homocysteine, high levels of which have been associated with possible heart disease.

    Vitamin B12 In Animals

    Vitamin B12 is produced both in animals and in humans by microorganisms that live mainly in the colon. Unfortunately, the point at which this occurs is beyond where absorption takes place in the small intestine most of this vitamin B12 is excreted unused and most animals rely on a dietary supply of the vitamin just like humans. An exception are ruminants, or grazing animals, which can self-produce the vitamin in their rumen.

    B12 source egg

    B12 source fish

    B12 source meat

    Carnivorous animals take in B12 through the meat of their prey, whilst non-ruminant herbivores obtain the vitamin through the combination of their food with soil and faeces.

    The daily dose does not necessarily have to be reached every day: like humans, animals also store a supply of vitamin B12 in their liver. This reserve is consumed only very slowly, so that a temporary shortage can be compensated for over several years. Nevertheless, a regular intake of the vitamin is recommended, as the first symptoms of a deficiency may occur even whilst the store is being emptied.

    The largest occurrence of vitamin B12 in animal foods is thus found mainly in the intestines in particular the point where the vitamin is produced, as well as in the liver where it is stored. The concentration of B12 progressively decreases from organs to lean meat, and then to milk or eggs. Nevertheless, some cheeses, such as camembert, may still contain quite large amounts of B12 due to how they are produced.

    How To Use Nutritional Yeast

    Nutritional yeast should be stored in a cool, dark place to preserve its vitamins. It should also be kept tightly sealed to keep moisture out.

    When properly stored, it can last up to two years.

    Nutritional yeast is used in the following ways:

    • Sprinkled over popcorn or pasta
    • Stirred into soups for an umami flavor
    • As a cheese flavoring in vegan sauces
    • As a thickener for soups and sauces
    • Added to pet food for extra nutrients

    Serving sizes are determined by each manufacturer but typically 1 or 2 tablespoons.

    It is safe to use nutritional yeast in moderation, typically up to several tablespoons per day.

    It would require relatively large amounts of nutritional yeast to exceed the tolerable upper intake levels for the various vitamins and minerals it contains. Specifics vary between brands, so always read labels to be sure.

    While nutritional yeast is safe to consume for most people, anyone who is allergic to yeast should not consume it .

    Those who have trouble metabolizing folic acid should read labels carefully and may want to choose unfortified nutritional yeast whenever possible.

    Summary Nutritional yeast is shelf-stable for up to two years and can be added to many foods for a nutty, cheesy or savory flavor and extra vitamins and minerals.

    Should You Take A Multivitamin

    Foods with B12 are always the first choice, but if you have trouble eating B12-rich foods, or have problems absorbing B12, another potential vitamin B12 source is a multivitamin. In fact, the federal government’s Dietary Guidelines for Americans suggest that people older than age 50 take a multivitamin supplement as a way to ensure adequate B12 intake.

    Many store multivitamins contain high amounts of B12. An average brand may contain about 25 mcg, which is more than 400% of the recommended daily value. Check with your doctor to determine if multivitamins is right for you. There is little risk from taking too much B12, however, high amounts may interact with certain medications.

    What Causes Vitamin B12 Deficiency Anemia

    You can get vitamin B12 deficiency anemia if you don’t get enough vitamin B12 in your diet from foods like milk, eggs, and meat. You’re more likely to be low in this vitamin if you’re older, or you eat a vegetarian diet. It can also happen if your body can’t absorb enough of it from the foods you eat.

    Your intestines absorb vitamin B12 from food. A protein your stomach makes called âintrinsic factorâ helps your body absorb it. When you don’t have enough, you have a type of vitamin B12 deficiency anemia called âpernicious anemia.â

    You can get pernicious anemia if:

    • You have an autoimmune disease that makes your immune system attack the cells in your stomach that produce intrinsic factor.
    • You have surgery to remove part of your stomach, where intrinsic factor is made.

    Your body also might not absorb enough vitamin B12 if:

    • You have a disease that affects how nutrients are absorbed in your intestines, such as Crohn’s disease, HIV, or some infections.
    • You have certain bad bacteria in your intestines.
    • You take some medicines, such as antibiotics and anti-seizure drugs.
    • You’ve had surgery to remove part of your intestines.
    • You’ve been infected with a tapeworm.

    It May Help Lower Cholesterol Levels

    The beta-glucan found in nutritional yeast may also lower cholesterol.

    In one study, men with high cholesterol who consumed 15 grams of beta-glucan derived from yeast daily for eight weeks lowered their total cholesterol levels by 6% .

    Another study found that mice fed beta-glucan from yeast had significantly lower cholesterol levels after only 10 days (

    25 ).

    Although the chemical structure of beta-glucan in oats is slightly different than the structure of beta-glucan in yeast, data suggests that they have similar cholesterol-lowering effects .

    However, no study to date has investigated whether consuming nutritional yeast in its whole form has the same effects. Further research is needed.

    Summary The beta-glucan in nutritional yeast may help lower cholesterol levels.
