10 Reasons To Eat Walnuts

A Healthy Snack

While walnuts (Juglans regia L) are a fall harvested tree food with nutrient-rich deliverables that are ideal for winter, their overwhelming health benefits should nominate them for a year-round source of protein, healthy fats and phytonutrients.

10 Reasons To Eat Walnuts

  1. Rich In Omega 3s

As most nuts are primarily mono-saturated fats, walnuts are loaded with omega-3 and omega-6 fatty acids as well. It is the only nut that is rich in omega-3, alpha-linolenic acid (ALA), which converts to the heart- and brain-healthy EPA and DHA omega-3 fatty acids. Of all edible plants, walnuts are the highest source of ALA – with a whopping 2.7 grams per one-quarter cup serving. (1)

  1. Free Radical Scavenger

They have the highest polyphenol content in a survey of various raw and roasted nut types. (2) The tannins and ellagic acids deliver some 14 different polyphenols that boosted superoxide dismutase (SOD), which may be the liver’s most potent free radical scavenger. Free radical scavengers have been shown to support healthy heart, vascular, nerve, bone, blood sugar and brain health. (2)

  1. Antioxidants – Eat The Skin!

Be sure and eat the very thin skin that wraps the nut inside the shell. It is slightly bitter but it stores the lion’s share of polyphenols. Some experts believe that 90% of them are found in the skin. Also because of the high-fat content, they should be refrigerated if you are not going to eat them quickly. They last longer unshelled and, if refrigerated, they will last up to six months.

  1. Healthy Cholesterol

The high-fat content of walnuts has been well-documented to support healthy cholesterol levels. Studies have shown that a diet rich in walnuts produces lower LDL cholesterol levels, by about 10 points on average. (3)

  1. Rich in Vitamin E

They are also high in the most active form of vitamin E called gamma-tocopherol, which is well-known to support cardiovascular health.

  1. They Make You Smarter

Walnuts are perhaps most famous for their support for cognitive function. With a strong physical resemblance to a brain, they do indeed make great brain food. In one study, eating just 1.5 ounces a day was shown to offer protection for an aging brain. (4)

  1. Reduce Brain Plaque

They have also been shown to inhibit the production of beta-amyloid plaque, which has been linked to a long-term decline in cognitive function, memory and learning. (5)

  1. Aids Weight Loss

In one study, overweight adults with type II diabetes who ate 1/4 cup of walnuts a day reduced fasting insulin levels compared to the group that did not eat walnuts. Excess insulin is one of the major contributors to excess storage of fat in the belly, hips and thighs. (6)

  1. Boost Sperm Count

Men who consumed 75 grams of walnuts which is just over 1/2 cup daily saw a significant increase in sperm count, motility and morphology. (7)

  1. Decrease Hunger

Eating walnuts for just three consecutive days was associated with a decrease in hunger and an increase in satiety, which is linked to weight loss. (8)

  1. I like how you mentioned that walnuts can aid in weight loss. I am trying to lose at least ten pounds. It seems like it would be a good idea for me to include organic walnuts in my diet.

  2. Thank you for explaining how walnuts can support healthy cholesterol. I’ve recently discovered that this is something I need to work on for my health. I’ll be sure to add walnuts to my diet to help with this.
