Phytochemicals Profile

Walnuts contain a variety of phytochemicals, which are naturally occurring compounds found in plants that have health-promoting properties. Some of the main phytochemicals found in walnuts include:

  • Polyphenols: Walnuts are a rich source of polyphenols, which are a type of antioxidant. Polyphenols have been shown to have anti-inflammatory and anti-cancer properties, as well as the ability to improve heart health by reducing cholesterol levels.
  • Phytosterols: Walnuts contain phytosterols, which are plant compounds that have a structure similar to cholesterol. Phytosterols have been shown to have cholesterol-lowering properties, which may help to improve heart health.
  • Omega-3 fatty acids: Walnuts are a good source of alpha-linolenic acid (ALA), a type of omega-3 fatty acid. Omega-3 fatty acids have anti-inflammatory properties and have been linked to improved heart health, brain function, and joint health.
