Green beans, this verdant pod, are one of the favourite vegetables. We appreciate their delicate taste, crunchiness, and nutrient richness. But do we know how to prepare them correctly? Unfortunately, many people make a simple mistake that can negatively affect their health. What are we talking about?

Green beans enjoy great popularity in our kitchens. We value them not only for their delicate, creamy taste but also for their numerous health benefits. This vegetable can be easily incorporated into a daily diet, whether as an addition to dinners, a component of salads, casseroles, pasta dishes, or soups. However, improper preparation can turn a healthy meal into something harmful. Did you know that eating green beans can be toxic if you make a common mistake?

Green beans - green poison on your plate?

Although green beans are incredibly healthy, when raw, they contain a toxic substance called phasin. This glycoside can cause severe stomach issues, such as vomiting, nausea, and stomach pain. Therefore, it is crucial to prepare this vegetable correctly. Cooking in boiling water effectively neutralises phasin, making green beans safe for consumption.

Spots reveal danger

Another threat to green bean lovers is spots on the pods. Their presence can indicate several problems:

  • Thermal stress: Storing beans in plastic bags for too long can lead to spots caused by high or low temperatures.
  • Pests: Silver or brown spots may indicate the presence of pea thrips.
  • Bacteria: Light brown spots with a watery edge can indicate bacterial blight caused by the bacterium Pseudomonas savastanoi.

In each case, the green beans are unsuitable for consumption and should be discarded.

How to safely prepare green beans?

To enjoy healthy and tasty dishes with green beans, follow these simple rules:

  • Thorough washing: Before preparation, wash the beans thoroughly under running water.
  • Remove damaged parts: Remove all damaged or spotted pods.
  • Cooking: Cook the beans in boiling water for an appropriate time.
  • Avoid fatty sauces: Instead of a breadcrumb topping, it is better to season the beans with olive oil, herbs, and garlic.

How to recognise fresh green beans?

To ensure you are buying healthy and tasty beans, pay attention to the following features:

  • Colour: Fresh beans should have an intense green colour. Avoid vegetables with yellowing or browning tips.
  • Crispness: Fresh beans should be firm and crispy.
  • No damage: Check that the pods are not damaged, crushed, or covered with spots.

Green beans are a valuable vegetable that can enrich our diet. However, to enjoy their taste without worrying about health, you need to pay attention to several important factors. Thorough washing, proper thermal processing, and choosing fresh vegetables are key to the safe preparation of green beans. Remember that health is the most important thing, so it is not worth risking consuming products that could harm your body.
