Citrus fruits
Citrus fruits like oranges, lemons, grapefruits, pineapples, etc., which are abundant in vitamin C, also contain strong antioxidants called flavonoids that go after free radicals, which are responsible for many diseases, including raising cholesterol and triglycerides
Flavonoids and other antioxidants, including vitamins, minerals, and flavonoids, are present in abundance in citrus fruits. Citrus flavonoids can reduce inflammation and help in the body's defense against the oxidation of LDL (bad) cholesterol by free radicals. Atherosclerosis development and progression are linked to oxidized LDL. This could be the reason why citrus consumption lowers the risk of heart disease and stroke, two conditions linked to atherosclerosis. Citrus fruits are also low in sugar and strengthen the immune system.
