Folic acid food sources

In terms of amino acids bacterial protein is similar to fish protein. The yeast s protein is almost identical to soya protein fungal protein is lower than yeast protein. In addition, SCP is deficient in amino acids with a sulphur bridge, such as cystine, cysteine and methionine. SCP as a food may require supplements of cysteine and methionine whereas they have high levels of lysine vitamins and other amino acids. The vitamins of microorganisms are primarily of the B type. Vitamin B12 occurs mostly hi bacteria, whereas algae are usually rich in vitamin A. The most common vitamins in SCP are thiamine, riboflavin, niacin, pyridoxine, pantothenic acid, choline, folic acid, inositol, biotin, B12 and P-aminobenzoic acid. Table 14.4 shows the essential amino acid analysis of SCP compared with several sources of protein.

Chilli peppers are the fruit of the Capsicumfrutescens, a plant that is native to Bolivia, where it was cultivated for more than 7,000 years before being transported to Europe - where at first it was not well received - and thence to India where it was much better appreciated. Chilli peppers are not just a spice but they are also a good source of vitamins A, C, and E. They are rich in folic acid and potassium, and low in food calories and sodium. Nevertheless, these benefits are minor compared to the major reason for adding chilli powder to our dishes, the aim being to make the food spicy hot. 

Carbohydrates are more plentiful and constant in food supplies throughout the world when compared to other nutrients, such as proteins, vitamin A, folic acid, and iodine. A naturally occurring deficiency specifically in carbohydrates is im-known. However, deliberate omission of carbohydrates from the diet with continued consumption of fat as an energy source can lead to specific problems. Glucose is required as an energy source by the central nervous system. When there is a deficiency of glucose, the body adjusts its metabolism to provide ketone bodies, nutrients derived from fat, which can be utilized by the brain and other parts of the central nervous system. However, excessive production of the ketone bodies can result in acidosis, a lowering of the pH of the blood, which is potentially toxic. 

Routes of exposure are oral, intravenous, intramuscular, and subcutaneous. Dietary sources of folic acid are green leafy vegetables, some fruits, legumes, eggs, yeast, whole grain cereals, lean beef, veal, liver, and kidneys. Heat destroys folic acid in cooked foods. 

The CDC suggests 400 meg daily for those two groups of people. The highest meg is found in lentils at 179 meg per half cup and fortified breakfast cereals, which have 146 to 177 meg per half cup. Spinach has 131 meg per half cup, orange juice 109 meg per cup, artichokes 95 meg per cup. Green peas, broccoli, com, and so on are all beneficial. Usually, natural sources are recommended. However, folic acid studies show that supplements are better because they are more easily absorbed the food-based folate acid.

Dietary folate intake determines folate nutritional status. It is therefore important to accurately measure folate in food using the best analytical platform currently available. In particular, folate analysis is confounded by several factors, such as the presence of many vitamers, low concentrations, physicochemical instability, and complex sample preparation [12]. It has been reported that the levels of endogenous 5-methyltetrahydrofolate and 5-formyltetrahydrofolate in canned chickpeas, a rich folate source, were 52 and 8 pg/lOO g, respectively [13]. Folate-fortified foods contain higher total folate concentrations than those found in natural folate-rich foods. We recently determined folic acid in Australian fortified bread varieties that was approximately 100 [tg/100 g [14]. 

Folic acid is widely distributed in nature green leafy materials, cereals and extracted oilseed meals are good sources of the vitamin. Folic acid is reasonably stable in foods stored under dry conditions, but it is readily degraded by moistine, particularly at high temperatures. It is also destroyed by ultraviolet light.
