What is Peanut Butter?

Peanut butter is a paste made from dry, roasted peanuts. This paste is generally used as a spread on toast or sandwiches. Peanuts, a type of ground nuts, belong to the family of Fabaceae and species of Arachis hypogaea. The plant itself is small in which the branch of the flower touches the ground and grows underneath. It is thought to have originated in the American continent and through Spanish travelers, it was spread all over the world. Unlike costly nuts such as cashew nuts, pistachio nuts, almonds, and walnuts, peanuts are low-cost nuts that offer similar benefits.

Health Benefits of Peanut Butter

Apart from its great taste, peanut butter has vital nutrients that are essential for the body. The health benefits of this tasty butter include the following:

Rich Source of Protein

Peanut butter (100 grams) contains a high amount of protein (25 – 30 grams). Proteins that we eat are broken down into amino acids, which are then utilized in each and every cell for repairing and building the body.

Lowers Cholesterol Levels

A 2016 research paper published in the Journal of Food Science and Technology has revealed that peanuts are an excellent source of compounds like resveratrol, phenolic acids, flavonoids and phytosterols that completely stop the absorption of cholesterol from the diet. The fat content in peanut butter is almost equal to that of the fats found in olive oil. It contains both polyunsaturated fats and monounsaturated fats. As these fats are not saturated, they are good to consume without putting the heart at any risk. The unsaturated fats in peanut butter help to lower bad cholesterol levels (low-density lipoprotein) and promote the circulation of good cholesterol (high-density lipoprotein).

Prevents Type 2 Diabetes

Consuming peanut butter can also be beneficial in reducing the risk of type 2 diabetes. Peanuts contain not only protein but also unsaturated fats. Unsaturated fats have been noted to improve insulin sensitivity. Research into peanut butter consumption and diabetes showed that a higher intake of peanut butter and other nuts lowers the risk of type 2 diabetes.

Good Source of Vitamins

Peanut butter contains many vitamins that are good for our body to function properly. Vitamin A found in it is helpful for eyesight, while vitamin C helps to boost the immune system and heals simple ulcers faster. On the other hand, the vitamin E found in peanut butter is a very important micronutrient needed by our body to dissolve complex fatty acid structures and fat blockages in the arteries.

Antioxidant Properties

Peanut butter contains antioxidant properties due to the presence of folate, niacin, pantothenic acid, pyridoxine, riboflavin, and thiamin. One of the antioxidants found in it is resveratrol. Resveratrol is a polyphenolic antioxidant which may help in controlling chronic diseases.

Anticancer Potential

According to Carol S Fink, Karen C Chan, Arthur C Downie et al’s study report published in the Nutrition and Cancer Journal, peanut butter contains B-sitosterol, a phytosterol that has a great property of fighting against cancer, particularly colon, prostate, and breast cancers. Peanuts and its products, such as peanut oil and peanut butter are ideal sources of phytosterols.

Regulates Blood Sugar Levels

Peanut butter is a good source of magnesium (170mg/100 grams). This makes up for 42% of the daily recommended value of magnesium. Magnesium has an important role to play in muscle, bone, and immunity development in the body. Magnesium also helps in regulating blood sugar levels and blood pressure. Its presence in our body helps in more than 300 biochemical reactions that are extremely important for our survival.

High in Potassium

Peanut butter contains potassium (70 mg/100g) that acts as an electrolyte and is a fluid-balancing element in the body. In comparison to sodium, which directly puts pressure on the cardiovascular system in the form of hypertension, potassium does not put any pressure either on the blood or on the cardiovascular system. In effect, potassium is a heart-friendly element that is found in high quantities in peanut butter.

Reduce Risk of Gallstones

Gallstones, a major health risk in developed countries, is caused by being overweight, crash diets, certain types of cholesterol drugs, and birth control pills. A study published in the American Journal of Clinical Nutrition on peanuts and nut consumption relating to the risk of gallstones was undertaken and the results of the study showed that over a period of 2 decades, women who consumed peanut butter and nuts on a regular basis had reduced their risk of developing gallstones.

Rich in Dietary Fiber

Peanuts and peanut butter are both high in dietary fiber. One cup or approximately 125 g of peanuts and peanut butter has 12 g and 20 g of dietary fiber, respectively. Dietary fiber is one of the most important parts of our diet since a lack of dietary fiber can lead to several health problems and diseases such as constipation, diabetes, cholesterol, and various heart diseases.

Word of Caution: Peanut allergies are one of the major risks associated with peanut butter, according to a survey conducted in the United States.

The symptoms of the allergy include vomiting, diarrhea, abdominal pain, anaphylaxis, asthma, and angioedema. If untreated, the anaphylactic shock can be fatal. According to the study, about 3 million Americans are presently affected by peanut and tree nut allergy.
