Your cells are under constant attack from free radicals — an unstable molecule with an unpaired electron that can damage cells, proteins, and DNA. They can be harmful to your physical health & mental health. Free radicals come from normal metabolic processes, as well as from pollution, radiation, cigarette smoke, and unhealthy diets.
Thankfully, antioxidants are your body’s defenders, and alkaline foods are their secret weapon. Incorporating these fruits and vegetables into your diet can help protect your cells, reduce inflammation, and fight oxidative stress.
What Exactly Are Antioxidants?
Antioxidants are molecules that neutralize free radicals by donating an electron, disarming them and preventing cellular damage. Common sources of antioxidants include vitamins C and E, selenium, and phytochemicals like flavonoids and carotenoids, which are abundant in alkaline foods such as leafy greens, berries, nuts, and seeds.
What Are the Health Benefits of Antioxidants?
By neutralizing free radicals, antioxidants provide a protective effect that can reduce the risk of chronic diseases such as heart disease, cancer, and neurodegenerative disorders like Alzheimer's disease. Additionally, eating a diet rich in antioxidants can enhance immune function and slow the aging process by preserving the integrity of cells and tissues.
