Posted on January 20, 2018August 1, 2019 by Marina Curilov

The walnut is the most widely-consumed nut in the world and is extremely rich in health benefits. This single-seeded stone fruit is of great help for our health and wellbeing, but how many walnuts a day should we eat and, most importantly, do they have any side-effects?

The U.S. Food and Drug Administration (FDA) have approved the claim for food labels that “eating 1.5 ounces per day of most nuts as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.”

But what are the reasons to eat walnuts every day?

Walnuts are among those valuable foods that help prevent from suffering from cardiovascular diseases, because eating walnuts daily helps reducing LDL cholesterol levels (bad cholesterol). This is due the fact that walnuts contain Omega-3 and Omega-6 polyunsaturated fats and vegetal sterols, which have a key role in keeping under control LDL cholesterol levels and triglycerides.

What is more, walnuts are extremely rich in arginine, an amino acid facilitating blood vessels dilatation and helping prevent clots.

#2 – Reduces the risk of suffering from diabetes and respiratory diseases

#8 – Support the brain and the nervous system

Walnuts have always been considered as ‘Brain Food’, perhaps because the surface structure of the walnut has a crinkly appearance like that of the brain. Omega-3 fatty acids and antioxidants nourish nerve cells, improve their functions and may even help prevent learning disabilities, depression, Alzheimer’s, etc.

Eating walnuts every day may also improve our mood and memory.

Because of their fair protein contents (24.9 g per each 100 g) walnuts may effectively cover for animal protein intake.

How many walnuts to eat a day?

The amount of fat, calories, and carbohydrate content found in walnuts is about 18 grams, 190 calories, and 4 grams, respectively per 1 ounce (about 30 grams). Therefore, it is believed that walnut consumption may result in weight gain. However, research conducted by Sabaté et al. (2005) at the Loma Linda University, California, USA have shown that walnut consumption of about 35 grams per day did not result in any significant weight gain among tested individuals over a period of 1 year.

Walnuts are extremely rich in valuable elements and are essential for the good functioning of our body, but they are quite caloric as well (612 Kcal per 100 g). Yet it is enough to eat 20-30 g (about 1 ounce) of walnuts a day (that’s around 6 walnuts), if included in a well-balanced diet and in an active lifestyle, in order to take advantage of all of the health benefits mentioned above.

If you don’t want to gain weight, you should eat walnuts in place of some foods or snacks. Just replace your traditional snacks with walnuts or eat them in the morning as part of the breakfast.
