Many people don’t think about integrating folate or folic acid into their diet until they’re trying to get pregnant, and indeed it is one of the prenatal vitamins given. But, studies are showing that folate has a much more extensive role; it is an important nutrient and key to maintaining optimal health. Furthermore, there is a direct correlation between lack of folate and alzheimers.
What is Folate, and What is the Difference Between Folate vs. Folic Acid?
First, let’s define what folate is: folate is derived from the Latin word “folium,” which means leaf. Green leafy vegetables, such as spinach or kale, as well as beans, fruits, fortified grains and lentils are great resources for folate intake. Diets that are rich in folate have been shown to decrease the risk of cardiovascular disease.
Let’s clear up a common misconception: that folate and folic acid are the same thing. Folate is a B-vitamin (vitamin B9 to be exact) that is naturally found in food. It’s needed to make DNA and other genetic material and is key for helping cells divide. Daily intake of folate is highly recommended for pregnant women or those who intend to become pregnant. Adding folate is highly important in the early stages of pregnancy since it helps a baby’s brain, skull, and spinal cord develop properly, which is why folate is given as a prenatal supplement. It is for this reason that women who are pregnant or place to become pregnant should increase their daily intake of folate.
Folic acid is the synthetic version found in supplements and fortified foods. It’s important to note that folate is not made by the body, which makes it an essential nutrient that we must get from outside sources, meaning our diet and eating foods rich in folate.
Given its importance, it is beneficial to know how your body metabolizes the folate that you ingest. A well-studied variant in the MTHFR gene has been linked to altered folate metabolism, resulting in lower folate levels and elevated plasma level of homocysteine which has been implicated in a wide range of negative health outcomes.
Well & Good, the popular health magazine states:
Now, there is one more key reason to zone in on folate. A new study published in Frontiers in Neuroscience found that there is evidence to show that the vitamin plays an important role in the development of Alzheimer’s Disease. Around 60 publications were included in the review, each of which had a sample size ranging from 24 to 965, to comprehensively evaluate the associations between Alzheimer’s and folate levels. The results showed that the folate level of Alzheimer’s patients was lower compared with that of the healthy controls.
The Fisher Center for Alzheimer’s Research Foundation states “Getting enough folic acid, a B vitamin critical for brain and nerve health, may help ward off Alzheimer’s in old age, a new study from the University of California at Irvine reports. Men and women aged 60 and up who regularly consumed the recommended daily allowance (RDA) of 400 micrograms (mcg) of folic through foods and supplements cut their risk of developing the brain-ravaging illness by over 50 percent.”
As folate aids in the growth of healthy cells, it isn’t difficult to make the leap to see proper folate as a protective factor for Alzheimer’s.
Folic Acid and the Gene Variation
The MTHFR gene codes for methylenetetrahydrofolate reductase, an enzyme. When you take a folic acid supplement, MTHFR converts the folic acid into L-methylfolate, also called 5-methyltetrahydrofolate (5-MTHF). This is the biologically active form of folate; in other words, it’s the type of folate our cells can use.However, if you have an MTHFR gene mutation, your body might have a hard time making this conversion. The most common genetic variant is the MTHFR C677T mutation, which is found in 20 to 40% of white and Hispanic individuals and 1 to 2% of black individuals in the United States.
Another variant, called the MTHFR A1298C mutation, is the second most common type. According to the journal Circulation, it’s found in 7 to 12% of people in North America, Europe, and Australia. It’s also found in 4 to 5% of Hispanic individuals, 1 to 4% of Chinese individuals, and 1 to 4% of Asian individuals.
Having a MTHFR gene mutation means your body is unable to efficiently code for MTHFR enzymes. This decreases normal enzyme function, or in some cases, totally turns it off. The result? Folic acid gets “stuck” and isn’t converted into a usable form. With high doses, unmetabolized folic acid can accumulate in the blood. (Generally, this isn’t a cause for concern—except for the fact that your cells aren’t getting the folate they need.)
In our programs at The Holistic Highway, we include genetic testing for any predisposition to low folate levels. If you have the gene mutation – it would be strongly recommended that you consider optimizing your daily intake of folate. One of the ways to increase your optimization is to add folate rich foods into your diet. Here are the top 7.
