How Much is 48 Grams of Walnuts?
When measuring nuts for recipes or daily consumption, using a digital scale is the most accurate method. However, understanding what 48 grams looks like in household measurements can be very helpful.
Number of walnuts
A standard 1-ounce (28-gram) serving of walnuts contains approximately 14 halves. Therefore, 48 grams is roughly 1.7 times that amount, which comes out to approximately 24 walnut halves. Remember that this can vary based on the size of the individual nuts.
Volume in cups
In terms of volume, 48 grams is approximately:
- Whole walnuts: A little over ⅓ cup.
- Coarsely chopped walnuts: A bit less than ½ cup.
- Finely chopped or ground walnuts: Just over ⅓ cup, as the pieces pack more densely.

Health Benefits of a 48g Serving
Regular consumption of walnuts, in amounts similar to a 48-gram serving, is associated with a range of health benefits supported by scientific research.
Supporting heart health
Walnuts contain high levels of omega-3 ALA, polyphenols, and phytosterols, which contribute to improved cardiovascular health. These compounds help to:

Enhancing brain function
The brain-like shape of the walnut is no coincidence, as the nutrients within are highly beneficial for cognitive health. The omega-3s, antioxidants, and polyphenols work to reduce oxidative stress and inflammation, which can protect against age-related cognitive decline.
Aiding gut health
Walnuts act as a prebiotic, providing fuel for beneficial gut bacteria. This can lead to a healthier gut microbiome, which in turn has a positive impact on overall health, digestion, and mood.
