Ginger is densely rich in antioxidants than many other foods. Only pomegranate and berries surpass it in terms of its antioxidant content.
Antioxidants help prevent oxidative stress, a process that is linked with diseases like diabetes, stroke and cancer. Oxidative stress happens when too many free radical molecules are produced by metabolic processes. Antioxidants help by stabilizing free radicals and preventing oxidative stress and thereby preventing us from diseases.
A study conducted in 2017 tested the antioxidant effects of ginger on cancer patients receiving chemotherapy. Patients who received the daily ginger extract had higher levels of antioxidants and lower levels of oxidative stress than the placebo group.
