Walnut — Food & Nutrition

What is Walnut?

A nut rich in omega-3 and Vitamin E that supports skin barrier strengthening and antioxidation

Rich in ALA (alpha-linolenic acid) omega-3, with anti-inflammatory and moisturizing benefits for dry skin.

Characteristics & nutrition facts

Walnuts are known to be rich in ALA (alpha-linolenic acid), a plant-based omega-3 fatty acid, as well as vitamin E, an antioxidant nutrient. Omega-3 fatty acids are known to be involved in the lipid composition of the skin barrier and may help reduce water loss and alleviate inflammatory responses. Vitamin E is known to exert antioxidant effects that protect cells from oxidative stress.

How to manage

Consuming about a small handful (approximately 28 g, 7–8 nuts) per day as a snack or added to salads or yogurt is generally recommended. Nuts are calorie-dense, and excessive consumption may be burdensome, so it is advisable to observe appropriate portions. If you have a nut allergy, consumption should be avoided and consulting a specialist when necessary is recommended.

Good to know alongside

Walnuts are frequently discussed alongside omega-3 fatty acids, unsaturated fats, vitamin E, and anti-inflammatory diets. They are mentioned as a component of a skin-moisturizing diet, together with the EPA and DHA found in oily fish.

Everyday care tips

The unsaturated fats in walnuts are prone to rancidity, so they should be stored in an airtight container in the refrigerator or freezer. They make a good everyday snack when dry or rough skin is a concern.
