The FDA’s Role in Food Classification
What Does Walnuts Mean to Be a “Healthy” Food?
For the FDA, a “healthy” food must meet certain nutritional criteria. It should be low in saturated fat, sodium, and added sugars while being rich in beneficial nutrients.
The Criteria for FDA Approval
Walnuts earned their “healthy” label because they are a natural source of unsaturated fats, omega-3 fatty acids, and essential nutrients.
Nutritional Benefits of Walnuts
Rich in Omega-3 Fatty Acids
Walnuts are one of the best plant-based sources of omega-3s, which are crucial for heart health. Regular consumption can reduce bad cholesterol levels and improve heart function.
High in Antioxidants
Packed with polyphenols, walnuts help combat oxidative stress, which can lead to chronic diseases like cancer and diabetes.
Walnuts Packed With Vitamins and Minerals
From promoting strong bones with magnesium to boosting energy with B vitamins, walnuts contribute significantly to overall health.
Health Benefits Backed by Research
Cardiovascular Health
Studies have shown that eating walnuts can lower LDL (bad cholesterol) levels while maintaining HDL (good cholesterol). Their anti-inflammatory properties also benefit heart health.
Brain Health
Walnuts have earned the nickname “brain food” for a reason. They contain compounds that support memory, focus, and overall cognitive function.
Weight Management
Despite being calorie-dense, walnuts are highly satiating, helping you feel full longer and reducing overall calorie intake.

Walnuts vs. Almonds
Walnuts are higher in omega-3s, while almonds excel in vitamin E content. Both are excellent for heart health.
