Blueberries Protect Cholesterol in Your Blood From Becoming Damaged
Oxidative damage is not limited to your cells and DNA.
It is also problematic when your “bad” LDL cholesterol is oxidized.
In fact, oxidation of “bad” LDL cholesterol is a crucial step in the heart disease process.
The antioxidants in blueberries are strongly linked to reduced levels of oxidized LDL. This makes blueberries very good for your heart (15Trusted Source).
The antioxidants in blueberries have been shown to reduce a predominant risk factor for heart disease by preventing oxidative damage to “bad” LDLcholesterol.
Blueberries May Lower Blood Pressure
Other studies have observed similar effects — especially for postmenopausal women (19Trusted Source, 20Trusted Source).
Regular blueberry intake is tied to lower blood pressure in numerous studies.
Blueberries May Help Prevent Heart Disease
While eating blueberries may lower blood pressure and oxidized LDL cholesterol, it’s important to keep in mind that these are risk factors — not actual diseases.
It would be much more informative to know whether blueberries help prevent hard endpoints like heart attacks, which are the world’s leading cause of death (21Trusted Source).
A study in 93,600 nurses found that those with the highest intake of anthocyanins — the main antioxidants in blueberries — were at a 32% lower risk of heart attacks compared to those with the lowest intake (22Trusted Source).
Because this was an observational study, it cannot prove that the anthocyanins alone caused the reduction in risk.
More studies are needed before any claims can be made. ufabet
