Cholesterol remains a highly popular subject for years. It is the cause of health problems for individuals who do not pay attention to their nutrition, resulting in diseases such as asthma, seizures, and obesity. Research continues to be conducted on new methods to prevent the development of many conditions. In this article, we shall present information on plant sterols, substances that provide an alternative to harmful LDL cholesterol.
What are phytosterols?
Phytosterols are chemical compounds of plant origin, whose structure is nearly identical to cholesterol, a chemical compound present in animal bodies. In plants, they primarily serve a protective function against herbivores by strengthening and hardening cell membranes, thereby increasing resistance to damage. Among phytosterols are stanols, which make up about 10% of this group of substances and have a significant impact on cholesterol levels. Therefore, phytosterols can be regarded as a natural stabilizer of lipid metabolism.
Properties of Stanols and Phytosterols
Stanols possess the capability of modifying cholesterol levels, which is the de facto primary function of the entire phytosterol group. The cellular structure of sterols and cholesterol is identical, which allows cells to be supplemented with plant substitutes. This results in a significant increase in the elimination of molecules (so-called bad cholesterol) and the prevention of absorption from the digestive tract. Cholesterol normalisation has a substantial impact on the improvement of metabolism and lipid metabolism. It is also a critical aspect of preventing cardiovascular diseases, which often have an abnormal cholesterol level as their basis. Regular use of phytosterols reduces the risk of developing diseases such as atherosclerosis, hypertension, hypercholesterolemia, or coronary heart disease. Plant sterols also exhibit a strong antioxidant and detoxifying effect, which is employed in treating cancer. Cancer cells are resistant to the destructive effects of the immune system, but systematic use of phytosterols leads to an enhancement of apoptosis, i.e., the programming of the pathological cell for self-destruction.
Dosage and origin of phytosterols
Due to their organic origin, phytosterols are primarily found in plant-based products. The main products for dietary enrichment should be vegetable fats, such as oils derived from corn, rapeseed, sesame, sunflower, and soybeans. Olive oil is also a good source of natural sterols. Almonds can also help cover daily needs. However, the biggest source of phytosterols is rice bran, whose daily intake can provide the body with up to 1200 mg of natural cholesterol. It is important to pay attention to proper dosage, as even the healthiest compounds can have negative effects if consumed in excess. It is recommended to consume a maximum of 3 g of phytosterols per day. Long-term supplementation in higher doses can lead to reduced absorption of fat-soluble vitamins (A, D, E, K). In case of overconsumption, systemic dysfunctions and the development of serious diseases can occur. It should be noted that despite the harmful effects of bad cholesterol, it is necessary for certain biochemical reactions in the body.
