Nutritional Significance Of Walnuts

They Are a Rich Source Of Healthy Fats 

Walnuts are a generous source of healthy monounsaturated fats, polyunsaturated fats, and Omega-3 fatty acids. Walnuts are rich in alpha-linolenic acid (ALA) which is an essential fatty acid and is extremely beneficial to your health.

A 28g serving of walnuts contains 2.5g of ALA (Plant source Omega-3 acid). This is more than the adequate intake required for both males and females in a day. Therefore, a cup of walnuts is a blissful source of your daily requirement of healthy Omega-3 fats.

Walnuts Have An Exquisite Vitamin And Mineral Content

The list of minerals and nutrients that walnuts are rich in is a long one. It is a great source of various significant minerals like manganese, copper, calcium, magnesium, phosphorus, potassium, and iron. The mineral content in walnuts is so rich that a 30g serving contains:

  • More than 10% of your daily iron requirement
  • About 15% of your daily magnesium requirement.

Along with these minerals, walnuts are also a rich source of Biotin (A b vitamin). Biotin is a nutrient important for your hair. Walnuts are also an amazing source of Vitamin E and vitamin B6 that contributes significantly towards your mental health.


We told you that walnut is not your run-of-the-mill nut. It contains a higher amount of antioxidants than any other common nut.

This antioxidant activity is a result of its rich vitamin E, Melatonin, and polyphenols (plant compounds). These antioxidants present in walnuts play a significant role in preventing damage to the body from bad cholesterol.

Glycemic Index Of Walnuts

  1. Walnuts have a low glycemic index: Walnuts have a low glycemic index, which means that they are less likely to cause a rapid increase in blood sugar levels compared to foods with a high glycemic index. Foods with a low glycemic index are generally considered to be better for blood sugar control and may be beneficial for people with diabetes or at risk for developing diabetes.
  2. Walnuts may have other health benefits: In addition to having a low glycemic index, walnuts are also a good source of nutrients such as fiber, protein, and healthy fats. They are also a good source of antioxidants, which may help to protect against oxidative stress and chronic diseases.
  3. Walnuts should be used in moderation: While walnuts have a low glycemic index and may offer some health benefits, it is important to use them in moderation as part of a balanced diet. Like any other food, eating too many walnuts can contribute to excess calorie intake and weight gain.

In conclusion, walnuts have a low glycemic index and may offer some potential health benefits. However, it is important to use them in moderation and as part of a balanced diet. If you have diabetes or are at risk for developing diabetes, it is always a good idea to talk to your healthcare professional about incorporating walnuts into your diet.

How Does Walnut Benefit Your Health?

Significant Benefits to Brain Functioning And Health

The nutrients along with the polyunsaturated fats, polyphenols, and vitamin E can help reduce inflammation in the brain.

These EFA’s also help in Neurogenesis (neuron creation) and play an important role in improving brain signaling.

Walnuts Reduce The Risk Of Cancer

Their hormone-like properties also help block hormone receptors and prevent hormone-based cancers like breast and prostate cancer.

The Omega-3 fatty acids in walnuts paired with these antioxidants are also known to fight cancer
