What Are Antioxidants?

If you want to know about plant-based chemicals that act as nutrients and also as natural protectors of our body, the answer is antioxidants. They help keep our cells healthy, boost our immunity, and slow down signs of ageing. The best part? You don’t need pills or powders. Eating a variety of colourful, fresh foods can provide your body with the antioxidants it needs.

Every day, our body produces free radicals, the tiny, unstable molecules. These free radicals enter our body through pollution, unhealthy food, stress, or even normal body processes. Too many free radicals can harm the cells of our body and may lead to early ageing or diseases like cancer and heart problems.  Antioxidants act like "bodyguards" for our body cells, providing immunity and helping protect our body from damage caused by harmful molecules called free radicals. Imagine your body is like a car. Free radicals are like rust trying to damage the car. Antioxidants are like the special paint or polish that protects it from rust.

So, where can we find these plant-based chemicals or antioxidants that can help protect our bodies and provide us with immunity? Antioxidants can be found in many plant-based foods and play a major role in boosting our immunity, slowing down ageing, and preventing chronic diseases. They are generally found in foods like fruits, vegetables, nuts, and herbs.

Let’s explore the top antioxidant-rich foods, the key antioxidants they contain, and how they help you stay healthy.

 Foods Rich in Antioxidants:

Many vegetables, fruits, nuts and herbs contain useful antioxidants that are helpful in keeping diseases away while providing immunity. We only need to identify them and make them part of our daily diet to maximise their benefits. Among the most common are vitamin C and vitamin E, which are found in fruits like citrus, berries, leafy greens, nuts, and seeds.  Here’s a list of antioxidant-rich foods you should add to your plate regularly:

 1. Berries 

Berries are the small, fleshy, pulpy and brightly coloured fruits containing many small seeds, with their tastes ranging from sweet, sour or tarty. They are among the richest natural sources of antioxidants, making them a powerful addition to any healthy diet. Some of them, which are loaded with antioxidants, are blueberries, strawberries, cherries and blackberries.

Blueberries are often called a superfood as they are one of the richest sources of antioxidants. They are especially high in 

1. Anthocyanins—a group of antioxidants that protect cells from damage and reduce inflammation throughout the body. Anthocyanin is also responsible for that deep blue colour of blueberries. 

2. Vitamin C, vitamin K and flavonols, the plant-based nutrients that help provide protection to your brain cells, improve memory, and support heart health. 

The antioxidants in blueberries make them especially beneficial for maintaining healthy skin, supporting the immune system, and reducing the risk of chronic diseases such as heart disease and type 2 diabetes. Eating a handful of fresh blueberries daily,or adding them to your oats, smoothies, or yoghurt, not only adds a burst of flavour but also gives your body a strong defence against harmful free radicals.

Strawberries are not only sweet and refreshing to eat, but they are also one of the most antioxidant-rich fruits you can eat. The great thing about strawberries is that they are packed with antioxidants like 

1. Vitamin C these powerful antioxidant helps boost immunity, support collagen production, and protect cells from oxidative stress. In fact, just one cup of strawberries can provide you with more than 100% of your daily vitamin C needs. So, all the strawberry lovers, this can be the major reason to eat them. 

2. Anthocyanins are the pigments that give strawberries their bright red colour and help reduce inflammation, support heart health, and can lower the risk of certain types of cancer.

3. Ellagic acid, a plant compound known for its anti-cancer and anti-ageing properties. 

Together, these antioxidants will slow down your ageing process and keep the skin glowing and healthy. Including strawberries in your daily diet, fresh, blended into smoothies, or added to yogurt is a delicious way to naturally strengthen your body’s defence system.

Cherries are vibrant, flavorful fruits that offer a powerful dose of antioxidants, making them a wonderful addition to a healthy diet. They are especially rich in

1. Anthocyanins, the pigments that give cherries their deep red colour and have strong anti-inflammatory and heart-protective properties. 

2. Vitamin C, which supports immunity and collagen production.

3. Polyphenols, known to protect against oxidative stress and reduce the risk of chronic diseases such as heart disease, diabetes, and certain cancers. 

4. Melatonin, a natural hormone that helps regulate sleep cycles. 

This makes cherries beneficial for improving sleep quality. Whether eaten fresh, dried, or in juice form, cherries are a delicious and health-boosting fruit that supports overall wellness and recovery

Blackberries offer a similar antioxidant profile with high levels of antioxidants 

1. Anthocyanins, famous for reducing inflammation and supporting heart health. Their deep purple-black colour comes from high levels of this antioxidant.

2. Vitamin C, which strengthens the immune system and promotes healthy skin. 

3. Ellagic acid, contributing to better skin, brain function, oral health and offering powerful protection against cellular damage. 

4. Vitamin K and folate, both of which are essential for bone health and cell growth. 

The high fibre content in blackberries further contributes to digestive health and helps maintain healthy blood sugar levels.
