Have you ever looked at the colorful vegetables and fruits you see when you go to the store or the market? Dark red tomatoes , orange carrots, purple eggplants, green vegetables… Seeing these colors makes you want to eat, and each of these colors is like a message to our body. Behind these colors are hidden many small chemical compounds that are very beneficial for our body and protect us from diseases . That's what we call phytonutrients. Today, let's talk about these amazing ingredients.
Simply put, what are these phytonutrients?
Very simple. “Phyto” means “plant” in Greek. “Nutrient” means “a nutrient.” Phytonutrients are the nutrients found in plants . These are also called phytochemicals.
Think about it, plants need to protect themselves from threats like diseases, insects, fungi , and the sun. These phytonutrients are chemicals that plants produce themselves for that protection. The amazing thing is, when we eat these plants, our bodies also get that protection.
These are not essential to our survival like vitamins and minerals . That means we won't die from a lack of phytonutrients. However, when added to our diet, they can help prevent many diseases and keep our bodies functioning properly. Scientists have so far identified more than 25,000 types of phytonutrients in plant foods.
Some of the main phytonutrients that are very important for our bodies are:
Out of these thousands, let's look at a few of the most talked about types that are particularly important for our health. This table will help you understand what they are, what foods they are found in, and what benefits they provide.
| Phytonutrient type | These are common foods. | Main benefits for the body |
|---|---|---|
| Carotenoids | Yellow, orange, red, and dark green vegetables and fruits like carrots, pumpkin, sweet potatoes, tomatoes, watermelon, spinach, and kale. | These are powerful antioxidants. They fight free radicals that damage cells in the body. Some carotenoids are converted into vitamin A in our bodies. This is important for vision and the immune system. Lycopene reduces the risk of prostate cancer. Lutein and zeaxanthin help prevent cataracts and age-related macular degeneration. |
| Ellagic Acid | Berries like strawberries, raspberries, and pomegranates. | Studies have found that it can help control the growth of cancer cells and remove cancer-causing chemicals from the liver. However, this has mostly been done in laboratory studies, so more needs to be done to understand its effects on the human body. |
| Flavonoids | Green tea, oranges, apples, onions, berries, kale. | This is a big category. Catechins in green tea help prevent some types of cancer. Hesperidin in oranges reduces inflammation in the body and protects against chronic diseases. Quercetin, a type of antioxidant found in apples and onions, may help reduce the risk of asthma, some cancers, and heart disease. |
| Resveratrol | Grapes (especially purple ones), red wine. | An antioxidant and anti-inflammatory compound. Some research suggests it may help reduce the risk of heart disease and some cancers. Animal studies have also shown it may have an effect on extending lifespan. |
| Glucosinolates | Vegetables like cabbage, broccoli, cauliflower, and Brussels sprouts. | These are the compounds that give these vegetables their characteristic pungent aroma and flavor. When we cook and digest them, they are converted into other chemicals that help control the formation and growth of cancer cells. |
| Phytoestrogens | Soybeans and soy-based products, flaxseeds, sesame seeds. | Their structure is similar to the hormone estrogen in our bodies. Therefore, they help balance estrogen levels in the body. There is some evidence that soy foods are linked to a reduced risk of uterine cancer and bone loss in women. |
How can we add these valuable things to our diet?
This is very easy. You don't have to make a big change, just think about a few small things.
The simplest secret is to “eat like a rainbow.” That means adding a variety of fruits and vegetables to your plate. The more colors you have, the more phytonutrients you get.
- Add a splash of color to every meal: When you eat rice, add a colorful vegetable, a pickle, or a sambol to it. For breakfast, eat a slice of tomato and a slice of cucumber with bread.
- Don't forget fruits: Make it a habit to eat one or two fruits a day. When you feel a little hungry between meals, eat a banana or an orange instead of a biscuit.
- Try new things: Instead of eating the same vegetables and fruits you eat every day, add a new vegetable or fruit to your diet at least once a week. Maybe something you've never eaten before is the best thing for your body.
- Be careful about how you cook it: Boiling vegetables for too long or frying them in oil can destroy these valuable nutrients. So it's best to boil them as little as possible or steam them.
Is food better than supplements?
These days, there are all kinds of phytonutrient supplements available in pharmacies. But remember, getting these nutrients from natural foods is always the best and safest way .
The reason is that there is not just one phytonutrient in a food. There are thousands of compounds that help each other. For example, the flavonoids, vitamin C , and fiber in an apple work together to provide the same benefits that you would get from taking a flavonoid pill.
Also, taking supplements in high doses can sometimes be harmful. Therefore, if you have a medical condition or are thinking of starting a supplement, be sure to talk to your doctor first for advice .
