Eftir því sem hugtakið heilbrigt mataræði verður sífellt vinsælli eru margar jurtaolíur sem innihalda plöntusteról á markaðnum, s.s.fytósterólog phytosterol repjuolíu. Hver er ávinningurinn af plöntusterólum fyrir mannslíkamann?
Fýtósteról vs kólesteról
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.
Meðal jurtaolíu er maískímolía með hæsta fytósterólinnihaldið, með heildar fytósterólinnihald meira en 1,000 mg í 100 grömm, síðan repjuolía og sesamolía. Í sojaolíu og hnetuolíu sem almennt er neytt af íbúum í norðurhluta landsins, er meðaltal fytósteróls 307 mg/100 g og 245 mg/100 g, í sömu röð. Lægsta innihaldið er kamelíuolía, sem er aðeins meira en 100 mg. Það má sjá að það að borða maískímolíu og borða meira heilkorn getur aukið neyslu plöntusteróla.
"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.
