When you go to the store, do you see beautiful vegetables and fruits that glow in orange, yellow, and red? Things like carrots, pumpkins, sweet potatoes, and papaya get that beautiful color because of a compound called beta-carotene. This is not just something that gives color. It is a super nutrient that is very valuable to our body and brings many health benefits. So today, let's talk about what this beta-carotene is and what benefits it gives us.
Simply put, what is beta carotene?
Beta-carotene is a nutrient that is converted into vitamin A after entering our bodies. To be precise, it is the precursor (provitamin A) of vitamin A. Beta-carotene helps our bodies make the amount of vitamin A they need.
Vitamin A is essential for our eyesight. Not only that, but it is also essential for the healthy functioning of major organs like our heart, lungs, and kidneys, and for cell growth.
In addition, beta-carotene is a powerful antioxidant , a hero that fights harmful particles called free radicals that damage our body's cells, causing various diseases and accelerating aging.
What are the main benefits of beta-carotene for our body?
Eating a diet rich in beta-carotene provides us with many health benefits. Let's take a look at the main benefits.
| Health benefit | Simple explanation |
|---|---|
| Eye Health | It converts into vitamin A and helps maintain good eyesight. Research has found that it can reduce the risk of diseases such as macular degeneration, which weakens eyesight, especially as we age, by about 35%. |
| Memory and Brain Function (Cognitive Function) | As an antioxidant, it helps protect brain cells and improve memory and learning ability. It may also help reduce the symptoms of memory loss that comes with aging and Alzheimer's disease. |
| Skin Protection | It helps keep the skin healthy and radiant. Beta-carotene also has the ability to reduce damage to the skin from harmful UV radiation from the sun. |
| Reducing the risk of cancer (Cancer Prevention) | Researchers have found that a diet rich in beta-carotene and other antioxidants can reduce the risk of some types of cancer, such as breast, lung, and pancreatic cancer. |
Is there a risk of taking too much beta carotene?
This is a very important point.
Vitamin A is a fat-soluble vitamin. This means that it can be stored in our bodies, especially in the liver. Taking too much vitamin A supplements over a long period of time can be toxic to the body. This can cause dizziness, nausea, joint pain, and in the worst cases, coma and even death.
But, the good news is that beta-carotene is almost completely safe. No matter how many beta-carotene-rich vegetables and fruits you eat, your body only makes the amount of vitamin A it needs and excretes the rest. Therefore, beta-carotene from food is not toxic.
However, if someone takes high doses of beta-carotene supplements for a long time, the only thing that can happen is that the skin will turn a yellow-orange color. This condition is called carotenemia. This is not dangerous, and the skin will return to normal within a few days once the supplements are stopped.
A very important warning: Research has found that people who smoke may be at increased risk of lung cancer if they take high doses of beta-carotene supplements. So if you are a smoker, never use beta-carotene supplements without medical advice.
How much beta carotene do we need?
There is no Recommended Dietary Allowance for beta-carotene. However, there is a recommended daily allowance for vitamin A based on age and gender. We can easily meet this vitamin A requirement by eating foods rich in beta-carotene.
The recommended daily allowances (mcg RAE - Retinol Activity Equivalents) for vitamin A are shown in the table below.
| Age group / occasion | Daily Vitamin A requirement (mcg RAE) |
|---|---|
| 1-3 years | 300 |
| 4-8 years | 400 |
| 9-13 years old | 600 |
| 14-18 years old (male) | 900 |
| 14-18 years old (girls) | 700 |
| Adult male | 900 |
| Adult women | 700 |
| Pregnant mothers | 770 |
| Breastfeeding mothers | 1300 |
What foods are rich in beta carotene?
It is best to get this nutrient from natural foods rather than supplements.
- Yellow and orange: carrots, sweet potatoes (especially yellow sweet potatoes), pumpkin, papaya, mango, dates.
- Green: Spinach, kale, collard greens, Swiss chard.
- Red: Red bell pepper.
A little secret: Beta-carotene is an oil-soluble nutrient, so it's easier for the body to absorb when you cook these vegetables with a little oil, like coconut oil, or when you make them into a sambal and eat them with coconut.
Adding these colorful fruits and vegetables to your diet is a good investment in a healthy lifestyle. If you need a supplement due to a medical condition or other reason, be sure to consult your doctor.
