Another superfood that reduces the risk of cancer is walnuts. These healthy nuts contain a good amount of polyphenols and phytochemicals that have antioxidant properties. They also are rich in anti-cancer compounds, such as ellagitannins, gamma-tocopherol, and alpha-linolenic acid.
A 2012 American Institute for Cancer Research study shows that walnuts help prevent breast cancer in animals. They can also reduce the risk of prostate and skin cancer.
Eat 1 ounce of walnuts daily (7 shelled walnuts) to reap the anti-cancer benefits. You can add walnuts to salads, soups or smoothies.
Both grapes as well as grape seed extracts are rich in the antioxidant resveratrol that offers anti-cancer benefits. It blocks the action of a protein that causes cancer growth. In addition, the anti-inflammatory properties of grapes prevent chronic oxidative stress and chronic inflammation, two main causes of cancer.
According to a 2005 study published in the Journal of Agricultural and Food Chemistry, the polyphenols from muscadine grapes exhibit anti-cancer properties.
Also, a 2009 study published in the Journal of Nutrition concluded that both grapes and grape-based products are excellent sources of various anti-cancer agents.
Eat a cup of grapes daily. If you prefer to take grape seed extract, consult your doctor for the correct dosage.
