What Are The Antioxidant Benefits And Sources

Hello,friends! Welcome to my blog, we’re going to learn about antioxidants—what they are, what they do in our body, their types, and the impact of their deficiency or excess. We’ll also see whether you get them from supplements or food, as antioxidants are becoming quite popular these days, and many people want to learn about them. So, let’s dive in and understand this topic.

First, let’s clarify what antioxidants are. Simply put, antioxidants are substances that control or neutralize the oxidants or free radicals produced in our body. Basically, our body undergoes reactions or inflammatory processes that require the production of oxidants. These could be superoxide, hydrogen peroxide, or lipid peroxides—all of which are free radicals. These free radicals are essential for processes like fighting infections or supporting metabolic functions. They can also be produced due to environmental toxins, excessive fatty acids, high sugar levels, or exposure to ionizing radiation.

So, these free radicals are naturally formed in the body, and we need them. But here’s the problem: if oxidants or free radicals build up excessively, they can damage our body’s cells. They can harm the DNA of cells or damage the cell membrane through lipid peroxidation. When these two things happen, the risk of diseases like cancer increases. Additionally, oxidative stress can contribute to diabetes, hypertension, heart problems, and lipid oxidation. It can also lead to inflammatory conditions like arthritis, skin damage, premature aging, hair issues, or various other diseases.

In short, when oxidants accumulate excessively, they can harm the body. To counter this, our body needs an antioxidant system to maintain balance. As I mentioned, oxidants like superoxide or hydrogen peroxide are necessary for fighting infections, bacteria, viruses, or fungi. We can’t eliminate the oxidant system entirely because it’s essential for these processes. What we can do is increase antioxidants in our diet to ensure a balance between oxidants and antioxidants.

Now, let’s understand the types of antioxidants. Broadly, antioxidants are divided into three categories: enzymes, vitamins, and minerals.

1. **Enzymes**: These include superoxide dismutase, catalase, and glutathione peroxidase.

2. **Vitamins**: The key antioxidant vitamins are Vitamin E (the most important), Vitamin A, and Vitamin C.

3. **Minerals**: Four minerals act as antioxidants—manganese, copper, zinc, and selenium.

These three types make up our antioxidant system. Enzymes are produced within the body, while vitamins and minerals can be obtained from food, particularly plant-based sources. So, by consuming the right foods, you can significantly boost your body’s antioxidant levels.

By now, you should understand that the body has an oxidant system (free radicals) and an antioxidant system. If we consume antioxidants in normal or adequate amounts, they can help prevent diseases like diabetes, arthritis, and other inflammatory conditions. They keep your skin and hair healthy, manage hypertension, reduce cancer risks, and maintain healthy lipid levels. Overall, antioxidants protect and enhance the body’s health, slow the aging process, and play a significant role in eye health.

Antioxidants can enter our body in two ways: through food rich in antioxidants or through supplements. Let’s briefly talk about supplements. Antioxidant supplements often come in tablet form and typically contain Vitamin A (beta-carotene), Vitamin E, Vitamin C, and minerals like manganese, copper, zinc, and selenium. There are also herbal antioxidant supplements, such as those made from grape seed extract, ginseng, ginkgo biloba, or lycopene. However, research suggests that supplements are less effective than antioxidants from food sources. Food-derived antioxidants work better in the body.

Now, let’s see some food sources. Foods rich in antioxidants include:

- **Fruits**: Almost all fruits are excellent sources of antioxidants.

- **Vegetables**: Especially green leafy vegetables.

- **Legumes and Pulses**: Like kidney beans (rajma).

- **Spices**: Such as turmeric, ginger, garlic, cinnamon, cloves, and saffron.

- **Other Sources**: Green tea, dark chocolate, and certain herbs like neem and aloe vera.

Foods with low or negligible antioxidants include dairy products (milk and milk-based items), meat, and grains. So, focus on fruits, vegetables, spices, and pulses for antioxidants, while dairy, meat, and grains offer minimal amounts.

When choosing fruits, antioxidants are highest in berries like blueberries, raspberries, blackberries, and strawberries. Other great options include pomegranates, papayas, apples, and peaches. A simple way to select antioxidant-rich foods is to focus on those high in Vitamin C (citrus fruits like oranges, lemons, or mangoes), Vitamin A (bright-colored fruits like papaya, bananas, or mangoes), and Vitamin E (avocados or leafy greens). Most fruits contain some level of antioxidants, so including a variety in your diet is key.

For spices, everyday options like garlic, ginger, turmeric, cinnamon, cloves, and saffron are packed with antioxidants. Among pulses, kidney beans and other legumes are great choices. For vegetables, tomatoes, beets, broccoli, and various beans are excellent. These contain minerals like manganese, copper, zinc, and selenium, which support the body’s antioxidant enzymes (like glutathione peroxidase and superoxide dismutase).

To summarize, I hope you now understand what antioxidants are, how they work, and where to find them. By including fruits, vegetables, green leafy veggies, and spices in your diet, you can easily get enough antioxidants. Meat, grains, and dairy products have minimal antioxidants, and fried or processed foods have almost none. I hope this gives you a clear picture of antioxidants and their importance. Thanks!
