Some foods are endowed with super powers that give you more energy and greater protection against disease. Eating a diet rich in blueberries, tomatoes, broccoli, and garlic will change your life for the better. By making these superpower foods part of your regular eating habits, you can actually change the course of your biochemistry and stop the gradual changes in your body that lead to diseases such as Alzheimer’s, cancer, high cholesterol, obesity, and diabetes.
The concept of superpower foods is supported by research. Studies on blueberries show that they have a positive effect on brain function and motor movement in aging rats. Blueberries also appear to prevent mental decline in mice genetically engineered to develop Alzheimer’s disease. Eating one cup of blueberries every day will reduce aging—related damage in our brain. Blueberries are an excellent source of antioxidants, nutrients in fruits and vegetables that neutralize the products of our metabolism before they can harm brain cells. Researchers believe that blueberries protect our brain through their antioxidant and anti—inflammatory action. Blueberries also seem to influence the way brain cells communicate with each other.
Tomatoes and tomato—based products are the major source of many carotenoids including lycopene. Research shows that lycopene, the red pigment in tomatoes, helps lower cholesterol and reduces the risk of prostate cancer. Studies show that the antioxidants in broccoli and cabbage help prevent colon cancer. Other studies show that garlic is the natural enemy of high cholesterol and the common cold. Eating foods with garlic or taking garlic supplements will produce a drop in LDL blood cholesterol.
