1. Red – Cancer-Fighting

Beet ROOT

Red fruits and veggies have amazing health benefits in addition to cancer-fighting properties. They contain two important phytochemicals – lycopene and ellagic acid. According to studies, daily consumption of tomato sauce counters the progress of prostate cancer. Watermelon is known to have even better results owing to its lycopene content. Additionally, it contains citrulline – a phytonutrient – that helps in the treatment of erectile dysfunction. Strawberries are known to prevent esophageal cancer and reverse its damage.
It must be noted that taking phytonutrients in the form of supplements might contribute towards the formation of cancerous cells. Instead, have whole foods that decrease the risk of cancer.

This category of fruits contains lutein that improves eye health and brain function and prevents cancer.
Some citrus fruits in this category contain hesperidin – a unique phytonutrient – that is associated with increased blood flow. Those who are more likely to get cold hands and feet must eat an orange or a tangerine a day. This helps keep hands and feet warm as well as reduce the risk of strokes.
