Walnut Nutrition Facts: Benefits of Eating Walnuts
The nutrition profile of walnuts includes various categories of nutrients. They are listed below along with their functions:
- Copper: This mineral is essential for heart health. It also helps with bone, nerve, and immune system function.
- Folic acid: Also known as folate or vitamin B9, it has many important biological functions in the body. Folic acid deficiency during pregnancy may cause birth defects in the newborn.
- Phosphorus: It is a mineral that is mainly present in bones. It has other functions in protein structure as well.
- Vitamin B6: Responsible for the proper functioning of your immune system and nervous system. Vitamin B6 deficiency is associated with anemia.
- Manganese: This trace mineral is found in all nuts, whole grains, fruits, and vegetables. It is required for various enzymatic functions in the body. Manganese works as a cofactor in several enzymes.
- Vitamin E: Among all nuts, walnuts contain high levels of gamma-tocopherol, which is a special form of vitamin E. This compound is known for its antioxidant properties.
Walnut Nutrition Facts: Other Compounds
Beneficial plant compounds in walnuts include:
- Ellagic acid: This antioxidant is found along with other chemically related compounds like ellagitannins. Ellagic acid is associated with a reduced risk of heart disease and cancer.
- Catechin: It is a flavonoid antioxidant that may have anti-inflammatory and antioxidant properties. Catechin is associated with improved heart health.
- Melatonin: This neurohormone also works as a powerful antioxidant that may reduce your risk of heart disease. Melatonin regulates your sleep cycle.

Walnut Nutrition Facts: Does It Help with Weight Loss?
Walnuts are allowed on the keto diet, paleo diet, and Mediterranean diet. Their low-carb profiles and dietary fiber content make them ideal for weight loss. They do not cause a spike in blood glucose and insulin levels, making them safe for type 2 diabetes mellitus. Stable insulin levels are associated with fat loss. However, added sugars in sweetened commercial nut trail mixes can increase the overall carb content as well as calorific value. Make your own trail mix of walnuts, almonds, and pistachios at home to get all the walnut nutritional benefits.

Ingredients:
- 1 cup of almonds, chopped
- 1 cup of walnuts, chopped
- 1/2 cup of roasted pumpkin seeds
- unsweetened coconut flakes (optional)
Procedure: Dry roast and mix all these ingredients. Let them cool and store them in an airtight container to get all the benefits of walnuts.

Walnuts are plant-based, naturally dairy-free, and ideal for a nutritious plant-based diet. Walnut's nutrition profile makes them ideal sources of fat and protein for vegans and vegetarians alike.
Walnuts have a lower impact on the environment than animal-based proteins and fats. The agriculture of walnuts requires less water than other crops.
Walnut Nutrition Facts: Good for Overall Health
A recent study, published in the journal Nutrition & Diabetes, which was conducted by the Royal New Zealand College of General Practitioners, has associated plant-based foods with decreased glycosylated hemoglobin (HbA1c) and total cholesterol levels.
