Calculating Calories in Ten Walnut Halves
Determining the exact calorie count for ten walnut halves requires a bit of estimation, as walnut sizes can vary. However, based on consistent data from trusted sources like the California Walnuts organization and Healthline, we can arrive at a reliable figure. A standard 1-ounce (28-gram) serving of walnuts contains approximately 190 calories and consists of about 12 to 14 halves. By using this information, we can make a simple calculation. If 12-14 halves average 190 calories, then ten halves would be slightly less. Dividing the total calories by the number of halves (190 / 13) gives us about 14.6 calories per half. Therefore, ten walnut halves contain approximately 146 calories.
Addressing Calorie Discrepancies
It is important to note that different sources may provide slightly varying calorie counts. Some online databases report higher or lower numbers, which can cause confusion. Factors that influence calorie estimates include:
- Size variation: The size of individual walnut halves can differ significantly. A larger, plumper half will naturally contain more calories than a smaller one.
- Moisture content: Raw walnuts can have varying moisture levels, which affects their overall weight and nutrient density per unit.
- Nutritional database differences: Different food composition databases may use slightly different data points or methodologies for their calculations.
Full Nutritional Profile of Ten Walnut Halves
Beyond just calories, ten walnut halves offer a rich profile of macronutrients and micronutrients that contribute to a healthy diet. Based on the 1-ounce serving (approx. 13 halves) of 190 calories, we can extrapolate the nutrient content for ten halves:

Health Benefits of Incorporating Walnuts
The healthy fats, antioxidants, and other compounds in walnuts contribute to numerous health benefits. Regular consumption of walnuts may support overall wellness in several key areas:
- Heart Health: The omega-3s and monounsaturated fats in walnuts have been shown to help lower LDL ('bad') cholesterol and triglycerides, reducing the risk of heart disease.
- Brain Function: The antioxidants and omega-3s can help reduce oxidative stress and inflammation, which may support better cognitive function and memory. Some research suggests they may even help with depression.
- Gut Health: Walnuts can act as a prebiotic, nourishing the beneficial bacteria in your gut. A healthy gut microbiome is linked to improved overall health.

Choosing and Storing Walnuts
To ensure you are getting the freshest and most nutritious walnuts, consider the following tips:
- Look for plump, firm halves that are golden brown in color. Avoid walnuts that appear shriveled or have an oily sheen, which can indicate rancidity.
- Store properly. Walnuts are high in oil and can go rancid if exposed to heat and light. For optimal freshness, store them in an airtight container in the refrigerator or freezer.
- Buy unsalted and raw or dry-roasted varieties to avoid excess sodium and unhealthy fats often added during processing.
- Consider buying in-shell if you have time to crack them. This can help preserve freshness for longer.
