Even in the short term, making changes to your diet can bring about dramatic improvements in your cholesterol levels and help address other risk factors for atherosclerosis.

Following the Paleolithic diet for ten days results in a significant reduction in blood pressure, blood sugar levels, insulin production, cholesterol, and triglycerides.

Follow the Paleolithic diet for ten days, and then switch to the Mediterranean diet, which includes plenty of fruits and vegetables, healthy fats (olive oil), nuts, and seeds.

High doses of vitamin C reduce the risk of cardiovascular disease. Research shows that the risk of heart disease decreases proportionally with the amount of vitamin C consumed. Recent research confirms that high doses of vitamin C from food protect against cerebral hemorrhages. Eating plenty of citrus fruits is therefore not only important for strengthening the immune system; it is also good for the heart and blood vessels.

An optimal dose of vitamin C keeps blood vessels healthy by ensuring that the inner lining of the blood vessels remains intact. This prevents blood clotting within the blood vessels themselves, allowing them to remain fully open. If the lining of the blood vessels malfunctions (endothelial dysfunction), blood will clot more quickly, proteins may leak out of the blood vessels, and the blood vessels may constrict.
