Antioxidants will help us avoid diseases caused by free radicals as they act to shield the cells from damage caused by the oxidation process.

Oxidation in our bodies destroys cell membranes and other cell structures, such as proteins, lipids, and DNA. This occurs as oxygen is metabolized, producing unstable molecules called free radicals. They steal electrons from other molecules, causing damage to cells and other cell components.

Such damage, caused by free radicals, can reach a point where it starts to affect the heart and liver and, in some cases, may lead to cancer as well. It is also recommended to be careful of catalysts that accelerate oxidation-including stress, cigarette smoking, alcohol intake, exposure to sunlight, and pollution.

Antioxidants are found in multiple foods and in the Harvard T.H. Chan School of Public Health publication, epidemiological prospective studies indicate that higher intakes of antioxidant-rich fruits, vegetables, and legumes are linked with a reduced incidence of chronic oxidative stress-related diseases such as cardiovascular disease and cancer.

We give you 5 antioxidant-rich foods to stock up to improve your immunity and provide you with the much-needed nutrient.

Dark Chocolates

Dark chocolate is filled with antioxidants and helps reduce body inflammation, 'bad' LDL cholesterol levels, as well as blood pressure. This nutritious and tasty treat is also effective when it comes to reducing the risk factors for heart failure.


This vegetable is filled with vitamins, minerals, and antioxidants (0.9 mmol per 100 grams) and is remarkably low in calories. Spinach is abundant in lutein and zeaxanthin-these antioxidants help protect the eyes from harmful UV radiation.


Beans are high in fiber and a rich source of antioxidants (2 mmol per 100 grams). Kaempferol is an antioxidant present in beans with proven health benefits such as decreased systemic inflammation and suppressed cancer formation, according to research reported by Science Direct.


Beetroot is a great ingredient with a rich nutritional profile. This vegetable provides a broad variety of important vitamins, fiber, antioxidants (1.7 mmol per 100 grams), and minerals and helps improve cell health, metabolism, bone growth, and the immune system. Betalain, an antioxidant present in beetroots, decreases the risk of cancer in the colon and the digestive tract and suppresses inflammation.


Blueberries are low in calories and are filled with nutrients and antioxidants. They have up to 9.2 millimoles per liter (mmol) of antioxidants per 100 grams. Antioxidants in blueberries, or anthocyanins, minimize risk factors for heart disease, lower levels of LDL cholesterol, and lower blood pressure.
