In ancient times, walnuts were referred to as ‘royal nuts’ since only people of royal heritage used to consume them. These tiny nuts are from Persia and are consumed throughout the world because of their multitude of benefits. Interestingly, their appearance resembles the human brain — and scientific research has supported that walnuts indeed support brain function. They are incredibly versatile and can be incorporated into the diet in many ways. In Hindi, walnuts are called Akhrot. Let’s dive into the various health benefits of walnuts (Akhrot).

Walnuts have many proven health benefits. These range from reducing the risk of heart issues, and cancer, to improving brain function. So let’s explore these interesting walnut benefits.
Research suggests that regular consumption of walnuts as part of a Mediterranean diet may reduce cancer-related mortality. This effect is attributed to their high content of omega-3 fatty acids, antioxidants, and phytosterols — all of which have anti-inflammatory and protective properties against cell damage and tumour development.
Various studies have shown that incorporating walnuts into your diet can significantly lower cholesterol levels.
Walnuts can assist with weight loss goals. Adding walnuts to your diet may be helpful and can be your ally in the weight loss journey.
Walnuts are rich in protein, fibre, and healthy fats, making them a suitable snack for people with diabetes. They have a low glycaemic index and do not cause significant spikes in blood glucose levels. Moreover, they may help improve insulin sensitivity and reduce the risk of developing Type 2 diabetes.
Chronic inflammation is linked to diseases such as type 2 diabetes, arthritis, and cardiovascular conditions. Walnuts contain polyphenols and alpha-linolenic acid (ALA), which have anti-inflammatory effects. Regular consumption may help manage inflammation and lower the risk of these chronic diseases.
Eating walnuts can assist in accelerating a slow metabolism. They’re filled with crucial fats and help with digestion, growth, and different bodily functions.
Walnuts contain calcium, magnesium, and phosphorus — minerals that are crucial for bone health. Their nutrient profile supports bone mineral density and helps in conditions like osteoporosis or calcium deficiency.
Walnuts are rich in dietary fibre, which adds bulk to stool and supports regular bowel movements. They also promote the growth of beneficial gut bacteria. Studies show that walnuts increase the number of butyrate-producing bacteria — a short-chain fatty acid that supports gut lining health and reduces inflammation. A healthy gut microbiome is linked to reduced risks of obesity, cancer, and metabolic diseases.
Walnuts contain polyphenols, vitamin E, and omega-3 fatty acids that help reduce oxidative stress and inflammation in the brain. Clinical observations in elderly individuals show that regular walnut consumption may improve memory, processing speed, and cognitive flexibility. While more studies are needed, the evidence so far is promising.
Walnuts are rich in antioxidants that help combat free radicals — unstable molecules that contribute to skin aging and dullness. Regular consumption may help improve skin elasticity and hydration and reduce under-eye dark circles. Their omega-3 content also supports hair strength and shine.
Women with PCOS often experience insulin resistance and dyslipidaemia. Walnuts have been shown to lower LDL (bad cholesterol) by up to 6%, enhance insulin sensitivity, and increase levels of sex hormone-binding globulin (SHBG), which can help regulate reproductive hormones and improve menstrual regularity. 12.

Walnuts contain tryptophan — an amino acid that the body uses to produce serotonin and melatonin, both of which regulate the sleep-wake cycle. Consuming walnuts in the evening may help promote restful sleep and improve overall mood.
