I have discussed the benefits of walnuts on this blog several times but wanted to point out another reason walnuts should be a part of your diet. Walnuts contain compounds that help lower LDL (bad) cholesterol! It is also believed walnuts can even help repair damaged arteries. Walnuts, as with everything, should be eaten in moderation. I am not saying to sit down and eat a bag of walnuts but to include them in salads, etc and it is okay to eat a handful from time to time.
