Why Are Vegetables Are So Bitter !?!
Do you love eating vegetables or do you avoid them like the plague? If you belong to the latter group, you might have wondered why some vegetables taste so bitter. Is it something wrong with your taste buds or with the vegetables themselves? The answer is: it depends.
Bitterness from Growing Conditions
Some vegetables are naturally bitter, such as kale, broccoli, Brussels sprouts, and arugula. These vegetables contain compounds called glucosinolates, which are responsible for their pungent flavor and health benefits1. However, the level of bitterness can vary depending on how the vegetables are grown and harvested.
According to some gardening experts23, bitter vegetables are a product of stress on plants. The chemicals that cause bitterness are usually present in the plant but can also move into the fruit. It can be caused by:
- Dry conditions: Hot, dry weather can produce bitter vegetables for long periods. Nothing can be done to regulate the weather, but you can water your plants regularly and mulch them to retain moisture.
- Lean soil: Other features of bitter vegetables are lean soil and a general lack of nutrients. Vegetables are heavy in feeding and need a rich, well-drained soil with plenty of organic matter. You can improve your soil by adding compost, manure, or fertilizer.
- Lack of sunlight: Some vegetables need full sun to grow well and produce sweet fruits. If they are shaded by other plants or structures, they may become bitter. You can avoid this by choosing a sunny spot for your vegetable garden or pruning any overhanging branches.
- Insect attacks: Pests and diseases can also stress your plants and make them bitter. You can prevent this by inspecting your plants regularly and removing any infected or damaged parts. You can also use natural remedies or pesticides to control the pests.
Bitterness from Storage and Harvest
Another factor that can affect the bitterness of your vegetables is how you store and harvest them. Some tips to avoid this are:
- Harvest at the right time: Some vegetables become bitter if they are harvested too early or too late. For example, cucumbers, zucchini, and eggplants should be picked when they are young and tender, while lettuce, spinach, and radishes should be harvested before they bolt (produce flowers). You can check the seed packets or labels for the best harvesting time for each vegetable.
- Store properly: Some vegetables lose their sweetness and become bitter if they are stored improperly. For example, tomatoes should be kept at room temperature and not in the refrigerator, while carrots, beets, and turnips should be stored in a cool, dark place with their greens removed. You can also blanch or freeze some vegetables to preserve their flavor.
- Prepare carefully: Some vegetables need to be prepared carefully to reduce their bitterness. For example, you can peel or seed cucumbers, soak or boil bitter greens, roast or steam cruciferous vegetables, or add salt, sugar, lemon juice, vinegar, or other seasonings to balance their flavor.
Bitterness from Genetics
Finally, some people may find vegetables more bitter than others because of their genetics. According to a recent study1, some people have variants in their genes that make them more sensitive to bitter tastes from certain chemicals such as glucosinolates. These people may avoid eating vegetables because they find them unpleasant.
However, this does not mean that they cannot enjoy vegetables at all. The study also found that people who were more exposed to bitter foods in their childhood were more likely to eat them as adults. Therefore, it is possible to overcome your genetic predisposition and acquire a taste for vegetables by trying different varieties and recipes.
Conclusion
Vegetables are an important part of a healthy diet, but they can also be bitter for various reasons. By understanding what causes bitterness in vegetables and how to prevent or reduce it, you can enjoy more delicious and nutritious meals with your favorite veggies.
