We often tend to eat protein bars as a quick and ready-to-eat snack for instant energy. Oats are often used as the main ingredient in protein bars as a source of proteins. Oats are scientifically known as Avena sativa, belonging to the family Poaceae. Oats are one of the most nutritious crops which contains carbohydrates, lipids, protein, and fibre. It is the 5th most consumed crop with an annual production of 23 million tons worldwide. Oat milk is a product made from oats and in recent days oat milk is emerging in the market due to its health benefits.1,2 Let us read the importance of oat milk benefits.

Potential Uses of Oat Milk for Overall Health:
Some of the potential benefits of oat milk are described as follows:
1. Potential use of oat milk for diabetes
Oat milk may help against diabetes and studies show that a bioactive dietary peptide in oat milk may improve insulin secretion and glucose digestion. Studies conducted on humans showed that intake of oat milk might improve fasting blood sugar level and insulin concentration. However, large-scale human studies are yet to be done to check the anti-diabetic effect of oat milk. It is important to check your blood sugar levels and get proper treatment in case of abnormal blood sugar levels.2

2. Potential use of oat milk to regulate blood pressure
Oat milk may regulate blood pressure and thereby improve heart health. A study on a rat model showed that the globulin peptide in oat milk might regulate blood pressure. Another human study showed that constituents like beta-glucans, dietary fibres, and avenanthramides might regulate blood pressure. Therefore, oat milk may reduce the risk of hypertension and might improve heart health. However, if you experience any abnormal blood pressure or symptoms of heart disease, you must immediately consult your doctor and take proper medications for the same.2 Do not self-medicate.
3. Potential use of oat milk for enhancing the immune system
Bioactive peptides present in oats may contribute to enhancing the immune system. It may help to enhance innate immunity (the first response of the immune system to foreign substances) and adaptive immunity (special immune cells in the body that destroy foreign substances). The exact mechanism by which the peptides in oat milk help improve immune function is unknown. Further research is to be done to claim the effect of oat milk on immune function.2
4. Potential use of oat milk for hypoxia
Hypoxia is a condition where the tissues in the body do not get enough oxygen. Bioactive peptides like oligopeptides in oat milk may reduce the risk of hypoxia and may increase haemoglobin. Haemoglobin, present in red blood cells, carries oxygen and transports it to various tissues in the body. In this way, oat milk may be beneficial in case of hypoxia. Further studies are required to confirm the effect of oat milk on hypoxia.2
5. Potential use of oat milk for exercise-induced fatigue
Oat milk may help in eliminating fatigue caused after strenuous exercise by improving muscle strength. Oat milk may improve muscle strength by decreasing the by-products of fatigue (lactic acid and blood urea nitrogen) and increasing the level of glycogen in muscles and the liver. Oat milk may reduce physical discomfort associated with exercise. Studies showed that oat milk might enhance the post-exercise recovery of damaged muscles. Further studies are yet to be done to check the anti-fatigue effect of oat milk.2
6. Potential use of oat milk to prevent platelet aggregation
Oat milk may inhibit the aggregation of platelets due to the presence of hydrolysates. Additionally, globulin in oats may inhibit platelet aggregation caused by arachidonic acid in the body. More research is yet to be done to confirm whether oat milk may prevent platelet aggregation.2

7. Potential use of oat milk to reduce cholesterol levels
Oat milk may possess cholesterol-lowering properties. The proteins present in oat milk may reduce the bad cholesterol by reducing cholesterol absorption in the intestine and increasing the faecal bile acid secretions. This study was done on animals. Large-scale human trials are to be done to check the effect of oat milk on reducing cholesterol in humans.2 If you have high cholesterol and obese consult the doctor for proper treatment. Do not self-medicate.
8. Potential use of oat milk for anaemia
Oat milk may be used to alleviate anaemia. This may be due to its antioxidant properties that reduce oxidative stress. Studies conducted on iron-deficient rat models showed that oat milk might help in the case of anaemia. More clinical studies are required to confirm the effect of oat milk on anaemia. However, you must seek proper treatment for anaemia instead of self-medicating.2
Though there are studies that show the benefits of oat milk in various conditions, these are insufficient and there is a need for further studies to establish the true extent of the benefits of oat milk on human health.
