1. Berries – The Antioxidant Powerhouses

Examples: Blueberries, Strawberries, Blackberries, Raspberries

Diseases Prevented:

• Cancer: Berries contain anthocyanins and ellagic acid, which help combat oxidative stress and reduce the risk of cancers such as colon, breast, and prostate cancer.
• Heart Disease: The high levels of polyphenols in berries improve blood circulation, reduce inflammation, and lower blood pressure.
• Brain Disorders: Studies show that regular consumption of berries can help prevent cognitive decline, reduce the risk of Alzheimer’s and Parkinson’s, and improve memory.

Example Research:

A study published in The American Journal of Clinical Nutrition found that individuals who consumed berries regularly had a 34% lower risk of heart disease than those who did not.

• Depression: Research has shown that omega-3s contribute to improved mood and a lower risk of depression and anxiety.
• Alzheimer’s Disease: DHA (docosahexaenoic acid), a type of omega-3 found in fish, plays a crucial role in brain health and reducing the risk of neurodegenerative diseases.

Example Research:

A study in JAMA (Journal of the American Medical Association) found that individuals who consumed fish at least twice a week had a 40% lower risk of dying from heart disease.
