Recent research results show that lutein has a delaying effect on the early progression of arteriosclerosis. It is mainly the relationship between the changes in the intima thickness of the main artery and the lutein content in the blood. Low lutein content in the blood can easily cause arterial wall thickening. As the lutein content gradually increases, the tendency of arterial wall thickening decreases, and arterial embolism is also significantly reduced. At the same time, xanthophylls in arterial wall cells can also reduce the oxidation of LDL cholesterol.
Many studies have shown that lutein has inhibitory effects on various cancers, such as breast cancer, prostate cancer, rectal cancer, skin cancer, etc. According to a recent study by the New York University School of Pharmacy, there is a close relationship between reducing the incidence of breast cancer and lutein intake. The survey found that the incidence of breast cancer in the experimental group with low lutein intake was (2.08-2.21) times that of the high-volume group. This effect may involve indirect immune regulation in collaboration with other organs and tissues. This study concluded that dietary intake of lutein can not only inhibit cancer but even prevent tumor occurrence. Relevant agencies recommend that a per capita daily intake of 400g to 600g of fruits and vegetables can reduce the relative risk of cancer by 50%.
