Antioxidants have become a buzzword in health and wellness discussions, even more so after the pandemic. But, what exactly are they? And why are they so important for you? Well, antioxidants are compounds that help neutralize free radicals — the harmful molecules produced in the body due to stress, pollution, and other environmental factors. 1 

While there are many types of antioxidants, plant-based sources are particularly important for people who follow vegetarian and vegan diets. Plant-based antioxidants can be found in a variety of fruits, vegetables, nuts, and seeds. In this article, we will explore the benefits of antioxidants and highlight some of its best plant-based sources. 

Benefits of antioxidants

Antioxidants are essential for maintaining optimal health. Here are some of the benefits of including antioxidants in your diet:

1. Fight free radicals: Antioxidants work by neutralizing free radicals, which can damage cells and contribute to the development of certain diseases. 2
2. Boost immune system: Antioxidants can help strengthen the immune system by promoting healthy cell growth, making it easier for the body to fight off infections.
3. Anti-aging properties: Antioxidants possess properties that help reduce the signs of aging by protecting cells from early damage.
4. Reducing inflammation: Antioxidants have anti-inflammatory properties, which can help to reduce inflammation in the body and alleviate symptoms of conditions such as arthritis and asthma.

1. Create a colorful salad: Create a salad with a variety of colorful fruits and vegetables, such as spinach, strawberries, blueberries, avocado, and almonds. Drizzle with a homemade vinaigrette made with antioxidant-rich ingredients like balsamic vinegar and extra virgin olive oil.
 

2. Add berries to your breakfast: Top your oatmeal, yogurt, or smoothie bowl with a mix of antioxidant-rich berries, such as raspberries, blackberries, and blueberries. You can also sprinkle some chia or flax seeds on top for an extra boost of nutrients.
 

3. Make a vegetable stir-fry: Stir-fry a mix of colorful vegetables, such as bell peppers, broccoli, carrots, and greens, with some antioxidant-rich spices like turmeric and ginger. Serve over quinoa or brown rice for a filling and nutritious meal.
 

4. Roast some sweet potatoes: Sweet potatoes are high in antioxidants and are a delicious side dish for any meal. Cut them into wedges, sprinkle with some cinnamon and paprika, and roast in the oven until tender and crispy.
 

5. Whip up a fruit smoothie: Blend a mix of frozen fruits, such as bananas, strawberries, and mangoes, with some almond milk and a spoonful of nut butter for a delicious and nutritious smoothie. You can also add a scoop of antioxidant-rich superfood powders, such as acai berry powder, for an extra boost.
 

6. Enjoy a fruit salsa: Salsa doesn't have to be tomato-based. Mix together some diced mango, pineapple, and papaya for a sweet and tangy fruit salsa that's loaded with antioxidants.
 

7. Relish dark chocolate in various ways: Look for chocolate that is at least 70% cocoa to ensure a high concentration of antioxidants. Simply enjoy a piece of dark chocolate as a treat regularly or blend some dark chocolate with your favorite plant-based milk, and a spoonful of nut butter for a decadent and filling drink. 
 

8. Try a cup of tea or coffee in the mornings: While a simple hot or cold cup of coffee or tea works wonders post breakfast, you could also make a spiced chai latte or mocha with some added dark chocolate sauce, or infuse them into baked desserts.
 

9. Add antioxidant supplements in your diet if needed: If you don’t get enough time to put together well-thought meals, you could opt for vegan supplements that are rich in antioxidants, such as Origins Nutra’s Astaxanthin. It is a powerful natural carotenoid from microalgae and 6000 times more potent than vitamin C, according to Origins Nutra. Its unique molecular structure makes it significantly stronger than any other antioxidant molecule. 

In addition to its antioxidant properties, astaxanthin also has anti-inflammatory properties, which can help keep your heart, muscles, joints and skin healthy. It is known to boost muscle endurance, reduce muscle damage, and improve energy levels and recovery. 

Astaxanthin also supports the immune system by increasing the production of white blood cells, and enhancing antibody production. Moreover, astaxanthin can improve cognitive function, including multitasking, alertness, and age-related forgetfulness.

Risks associated with high dosage of antioxidants

While antioxidants are important for protecting the body from free radicals, excess consumption should be avoided. In some cases, high doses of antioxidants can have pro-oxidant effects, leading to increased oxidative stress and damage to cells. Some people may be allergic to certain antioxidants, and consuming high doses can increase the risk of an allergic reaction. High doses of antioxidants, such as beta-carotene and vitamin E, may also increase the risk of certain cancers, such as lung cancer in smokers. 5
 

Conclusion

Thus, if you are considering taking antioxidant supplements, it is important to consult with a healthcare professional to determine if they are appropriate for your specific needs and to ensure safe usage.

However, incorporating some amount of antioxidants into your daily diet can have numerous benefits for your health and well-being, and there are several ways to receive them from plant-based sources. So why not start today and give your body the antioxidants it needs to thrive?
