The effect is better with garlic than with onion. Recently, an alkyl disulfide has been proposed from these two plants, which has a hypolipidemic effect on both humans and animals. Kelp and nori: In addition to being rich in beneficial elements such as iodine and magnesium, they also contain kombucha, fucoidan and kombucha polysaccharide, which have been shown to have significant hypolipidemic and anticoagulant effects, some of which will also be used clinically as drugs to lower blood lipids and prevent atherosclerosis.
