Atherosclerosis is a complicated condition because it can cause a number of different symptoms in the body, from higher blood pressure to shortness of breath and chest pains. Spinach is one of the best recommendations for the diet of someone at high risk of atherosclerosis, as the blend of antioxidants and minerals in spinach is ideal for reducing inflammation in the body. This can reduce tension and contraction of blood vessels, which makes it easier for blood to flow and more difficult for clots to cause problems. Spinach can be eaten in many forms, but boiling or cooking spinach does reduce overall nutrient content.
