Folic Acid And BHT

Folic acid is a synthetic form of the B vitamin folate, which is naturally found in leafy green vegetables and fruits. It is made chemically and is often added to foods to increase their nutritional value. Butylated hydroxytoluene (BHT) is a synthetic antioxidant that prevents foods from spoiling by inhibiting the action of oxygen.

Folic acid is added to foods as a nutrient to help prevent certain birth defects. BHT is added to foods as a preservative to extend shelf life by preventing oxidation, which can cause fats and oils to go rancid. They are often found in baked goods like cakes and cookies, as well as candies.

Folic acid is recognized as safe and effective by the FDA when used as a nutrient in fortified foods. The FDA has also affirmed BHT as Generally Recognized As Safe (GRAS) for use as a food preservative. Both the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated these ingredients. While generally considered safe at typical intake levels, some studies have explored potential effects of BHT at very high doses, though evidence is mixed and not conclusive at levels found in food.
