I takt med at konceptet med sund kost bliver mere og mere populært, er der mange vegetabilske olier indeholdende phytosteroler på markedet, som f.eks.phytosterolog phytosterol rapsolie. Hvad er fordelene ved plantesteroler for den menneskelige krop?
Phytosteroler vs. Kolesterol
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.
Opnået gennem kosten
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.
Blandt vegetabilske olier har majskimolie det højeste fytosterolindhold med et samlet phytosterolindhold på mere end 1,000 mg pr. 100 gram, efterfulgt af rapsolie og sesamolie. I sojabønneolie og jordnøddeolie, der almindeligvis indtages af beboere i det nordlige mit land, er det gennemsnitlige indhold af phytosterol henholdsvis 307 mg/100 g og 245 mg/100 g. Det laveste indhold er kameliaolie, som kun er mere end 100 mg. Det kan ses, at spise majskimolie og spise mere fuldkorn kan øge indtaget af phytosteroler.
"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.
