Ker je koncept zdrave prehrane vse bolj priljubljen, je na trgu veliko rastlinskih olj, ki vsebujejo fitosterole, kot npr.fitosterolin fitosterol repično olje. Kakšne so prednosti rastlinskih sterolov za človeško telo?
Fitosteroli proti holesterolu
Phytosterols are sterols with structural and biochemical properties similar to cholesterol. This "fatoid" is widely found in the roots, stems, leaves and fruits of plants. Although phytosterols "look" similar to cholesterol, they compete with each other in the human body. The higher the dietary intake of phytosterols, the lower the absorption rate of cholesterol and the lower the serum cholesterol level. Elevated cholesterol can cause blood vessel blockage and disease.

The excellent cholesterol "nemesis" such as phytosterols cannot be synthesized autonomously in human cells. The only way is through dietary intake. As their name suggests, Phytosterols are widely found in plants in nature. Foods high in phytosterols include vegetable oils, dried beans, and nuts in the daily diet. In cereal foods, the content of phytosterols in flour is relatively high, about 47-76 mg of phytosterols per 100 grams of flour. The finer the flour is processed, the lower the phytosterol content, namely whole wheat flour ﹥ standard flour ﹥ rich and strong flour ﹥ dumpling flour.
Med rastlinskimi olji ima olje koruznih kalčkov najvišjo vsebnost fitosterola, s skupno vsebnostjo fitosterola več kot 1,000 mg na 100 gramov, sledita repično olje in sezamovo olje. V sojinem olju in arašidovem olju, ki ju običajno uživajo prebivalci severne moje države, je povprečna vsebnost fitosterola 307 mg/100 g oziroma 245 mg/100 g. Najnižja vsebnost je olja kamelije, ki je le več kot 100 mg. Vidimo lahko, da uživanje olja koruznih kalčkov in uživanje več celih zrn lahko poveča vnos fitosterolov.
"The Key to Life"
Scientists have hailed Phytosterols as "the key to life" because of their ability to lower cholesterol levels and protect cardiovascular health. Studies have found that a 10 percent reduction in blood cholesterol levels will reduce cardiovascular disease by 19 percent -54 percent . Therefore, it has been strongly recommended by world authoritative organizations such as the World Heart Organization, American Heart Association, British Heart Foundation, German Society of Nutritional Medicine and Dietetics, Australian Heart Association, etc.
