Hazelnuts and chestnuts are packed with essential nutrients such as fiber, protein, vitamins, iron, calcium, and magnesium. However, when you compare their nutritional values in detail, you will find some quirky facts about their differences.


In nutrition, calories measure the amount of energy you get from foods. The greater the number of calories you consume, the more energy you obtain.

The immune system is the body’s defense against potentially harmful viruses and bacteria. It fights infections and aids in the healing of wounds. The stronger your immune system, the less susceptible you will be to disease.

Adequate vitamin C consumption helps prevent and treat respiratory and systemic infections by enhancing various immune cell functions.

Being a rich source of vitamin C by containing 26.7mg in just 100gm chestnut is slightly better for boosting immunity.

However, vitamin C is not the only nutrient that influences your immune system’s health.
