This is the perfect time to start focusing on diet and lifestyle changes as well as starting a few key supplements. Inflammation is the main cause of plaque formation. You need to focus on lowering overall inflammation. You can do this by eating a whole foods, plant based diet, and supplementing with antioxidants. Essential fatty acids, like cod liver oil and fish oil, decrease inflammation and help thin the blood. Hawthorne berry extract is a great herb for protecting the cardiovascular system. Vitamin C and bioflavonoids help strengthen the blood vessels. Your diet should be centered around vegetables and lean protein, some fruits, whole grains and healthy fats from nuts, seeds, olive oil, and organic butter. Exercise! Good luck!
