Berries

Berries include significant levels of anthocyanins and plant pigments with antioxidant properties that may lower the risk of cancer. One human trial involved 25 patients with colorectal cancer who received bilberry extract for seven days. It was discovered that this treatment slowed the growth of cancer cells by 7%.

Another small study revealed that giving freeze-dried black raspberries to patients with oral cancer reduced levels of several cancer-related indicators. According to one study on animals, feeding rats freeze-dried black raspberries decreased the incidence of esophageal tumors by up to 54% and the number of tumors by up to 62%. Similar to this, another study on animals showed that giving rats berry extract inhibited many cancer biomarkers. These results suggest that consuming a serving or two of berries daily may help prevent the growth of cancer. Remember that further human research is required because these studies, which examined the effects of a concentrated dose of berry extract, were animal and observational studies.
