1, minor
Minors can't eat evening primrose mainly because evening primrose oil contains γ-linoleic acid, which can be converted into hormones in human body. Minors secrete hormones themselves, which may affect normal menstruation or normal growth and development if they ingest hormones.
2. Menstrual women
Menstrual grass is also called evening primrose, mainly because it has very small yellow flowers at night. Generally speaking, eating evening primrose can regulate menstruation, but it is not suitable for menstrual women. Because women secrete the least progesterone hormone during menstruation, this is because if they ingest menstrual grass that can synthesize hormones in the human body, it will disturb the secretion of hormones.
3. Pregnant women
Because pregnant women belong to a special group, if pregnant women eat evening primrose, it may cause hormonal changes in pregnant women and affect maternal and child health.
4, the characteristics of evening primrose
Evening primrose is a plant of Salicaceae, which has a big red spot on its stem. Leaves lanceolate, with wavy edges; Flowers yellow, four petals; Capsule is slender. Native to North America, it is now widely distributed in temperate regions and grows in open areas, especially sand dunes and sandy areas.
5. The principle of evening primrose.
Evening primrose is rich in essential fatty acids, especially linoleic acid (about 70%) and γ -linolenic acid (GLA) (about 9%). GLA, as the main active ingredient, is the precursor of prostaglandin E 1 (a hormone), which is often combined with vitamin K to play an antioxidant role.
6, the efficacy of evening primrose
1, reducing blood lipid
Evening primrose contains a lot of unsaturated fatty acids, mainly linoleic acid, linolenic acid and oleic acid, and a small amount of palmitic acid. These plant acids are mostly unsaturated fatty acids, which have certain antioxidant effects. After eating, it has a good effect on removing cholesterol and low density lipoprotein from blood, reducing blood lipid and preventing thrombosis.
2, lowering blood sugar
Evening primrose contains alloxan, which can strongly enhance the sensitivity of diabetic patients to insulin, and the unsaturated fatty acids in evening primrose can also promote the synthesis of prostate E 1. Prostate E 1 has insulin activity and can also play a certain role in lowering blood sugar.
Step 3 lose weight
Evening primrose contains unsaturated fatty acids, which can remove low-density lipoprotein and saturated fatty acids from blood vessels. Evening primrose can also inhibit the thickening of intestinal villi, regulate the digestion and absorption function of gastrointestinal tract and reduce the accumulation of fat in the body.
4, anti-fatty liver
Too much saturated fatty acid in the body is the main factor leading to fatty liver. The unsaturated fatty acids contained in evening primrose can help clear cholesterol in the body, promote the digestion of saturated fatty acids, and have certain antioxidant effects, alleviate the aging of liver cells and have certain anti-fatty liver effects.
Step 5 fight cancer
Evening primrose contains a variety of antioxidants, such as vitamin C and unsaturated fatty acids, which can scavenge free radicals in the body, slow down cell aging and inhibit the formation of cancer.
6. Relieve premenstrual symptoms
In women, when menstruation begins about two or three days ago, the concentration of inflammatory factor prostaglandin will increase due to hormonal changes and endometrial bleeding during menstrual cramps. GLA contained in evening primrose oil can inhibit the increase of prostaglandin concentration that causes inflammation and reduce the uncomfortable reaction of PMS.
