Commonly used pollen includes pine pollen, rape pollen, osmanthus powder, rose powder, chrysanthemum powder and so on. Modern scientific analysis believes that pollen is not only the source of life for plants, but also a "mini-nutrition treasure house". According to the determination, the protein content of pollen per 100g can be as high as 25 ~ 30g, which contains more than a dozen amino acids and is in a free state, so it is easy to be absorbed by human body. This is unmatched by any other natural food. Pollen also contains 40% sugar and a certain amount of fat, as well as rich B vitamins, vitamin A, vitamin D, vitamin E and vitamin K, among which vitamin E and vitamin K are important substances that have been proved by scientists to delay the aging process of human cells and prolong life. Pollen also contains more than ten kinds of inorganic salts such as iron, zinc, calcium, magnesium and potassium, more than 30 kinds of trace elements and 18 kinds of enzymes, as well as nucleic acids and some hormones, auxins and antibiotics that can delay human aging. Therefore, pollen is a multifunctional nutritious food.
Pollen is not only a nutritious food, but also has a good medical function. Clinical experimental data show that pollen has certain therapeutic effects on diabetes, kidney calculi's disease, gastritis, hepatitis, anemia, insomnia, neurasthenia, tracheitis, prostatitis and cardiovascular diseases. It is reported that wild rose pollen can treat kidney calculi, apple pollen can prevent myocardial infarction, hawthorn pollen can be used as cardiotonic agent, and chestnut pollen can enrich blood and reduce prostate congestion.
Pollen food has also been proved to be an effective enhancer of physical strength and endurance. Because it contains an efficient bioactive substance, it can improve the metabolism of human tissues and organs, enhance cardiovascular function and delay aging, so pollen is a food that can make people keep fit and prolong life.
