Walnuts have also been shown to aid in the lowering LDL cholesterol (the bad cholesterol) and the C-Reactive Protein (CRP). CRP was recently recognized as an independent marker and predictor of heart disease.

FDA Approved Health Claim for Walnuts
In 2003, the FDA recognized the benefits of nuts and their role in heart disease prevention by approving a health claim for 7 kinds of nuts (almonds, hazelnuts, peanuts, pecans, some pine nuts, pistachios and walnuts). These seven nuts were approved as they are the only kinds that contain less than 4 grams of saturated fats per 50 grams.
In response to a petition filed by the California Walnut Commission, the FDA further endorsed the health benefits of walnuts by approving the following health claim in March 2004.
“Supportive but not conclusive research shows that eating 1.5 oz of walnuts per day, as part of a low saturated fat and low cholesterol diet, and not resulting in increased caloric intake may reduce the risk of coronary heart disease.”
Adding Walnuts in a Healthy Diet
Nuts in general are high in calories, so moderation is the key. The best approach is to reap the health benefits of eating walnuts but not add excessive calories to your daily intake. Therefore, instead of just adding walnuts to your current diet, eat them in replacement of foods that are high in saturated fats (such as cheese and meat) and limit your intake of these tasty treats to the recommended 1.5 oz per day. That is about 20 walnut halves.
Walnuts add a flavorful crunch to dishes. Here are some simple ideas to incorporate walnuts in your diet to reap their health benefits:
- instead of snacking on cookies, crack some walnuts open and eat them as snacks
- instead of using meat, toss toasted walnuts in your salad or pasta to add some crunch
- instead of layering pepperoni, use chopped walnuts in your pizza
- instead of eating bacons or eggs, use walnuts as a protein choice by sprinkling chopped walnuts in your oatmeal or breakfast cereal
