Pistachio, also known as "longevity fruit," is a type of walnut and is one of the 17 types of walnuts in the world. Its nutritional value is comparable to that of walnuts and it is considered a high-end therapeutic health food. The edible part is the kernel inside the fruit shell, which is plump and has a delicious flavor. Pistachios can be eaten raw or roasted, used in dishes or consumed as a snack. So, what are the nutritional values of this type of walnut?
Pistachios are rich in fats
Pistachios, like other walnuts, contain a large amount of oil, accounting for about 40-50% of their dry weight. Most of the fats are unsaturated fatty acids, which can help reduce the levels of low-density lipoprotein and low-density cholesterol when consumed. This can prevent and treat cardiovascular diseases. Therefore, pistachios are suitable as a health food for middle-aged and elderly people.
Pistachios are high in protein
Protein is the foundation of life, and life is nothing but a manifestation of protein. The human body needs to intake a certain amount of protein every day to ensure normal life activities. Pistachios have a high protein content, and most of them are high-quality proteins. Research has shown that the protein content in one kilogram of pistachio kernels is equivalent to nine kilograms of fresh milk. Therefore, consuming a small amount of pistachios every day is a good way to supplement protein.
Pistachios are rich in vitamins
Pistachios are fruits of plants and contain many vitamins, with the highest content of vitamin E. Vitamin E, also known as tocopherol, plays an important role in regulating reproduction. It can regulate the secretion of estrogen in women, promote the growth and development of eggs, and improve the quality and quantity of sperm in men. Therefore, consuming pistachios has a certain regulatory effect on infertility in both men and women.
Pistachios are rich in minerals
Pistachios generally have a high mineral content, although it may vary due to their growth environment. The kernels contain a higher amount of trace elements zinc and manganese, which are important components of the pituitary gland. Regular consumption of pistachios can effectively replenish trace elements for the brain, promoting brain health and intelligence development. It is suitable for consumption by middle-aged and elderly people and children, as it can promote intellectual development and slow down cognitive decline in the elderly.
Pistachios contain propionic acid
Walnuts, including pistachios, contain a certain amount of propionic acid. Propionic acid can prevent the binding of mucin, calcium ions, and unconjugated bilirubin, and dissolve, fade, and excrete them. Therefore, patients with gallstones may consider eating pistachio kernels every day to potentially avoid surgery. Similarly, pistachio kernels can also be used to treat urinary stones.
