Do you know the 3 best cooking methods?

These three gentle methods best preserve vegetables' nutritional qualities.

1. Pressure cooking

The pressure cooker uses minimal water turned to steam under pressure, retaining color and nutrients. It's one of the quickest methods (just 1-2 min).

2. Microwaving

Microwaving is fastest and akin to steaming. Use little water to keep nutrients intact—for asparagus, add just 2-3 tablespoons.

3. Steaming

Steaming in a basket preserves nutrition if you use minimal water (about 120 ml, boiled first) and short times—5-7 min for most vegetables.

Additional tips

- Vegetables' enzymes halt vitamin production post-harvest but can cause losses. Refrigerate most until cooking to slow this.

- Oxidation-sensitive vitamins require airtight storage for cut or juicy vegetables in the fridge.

- Water-soluble vitamins (like C and B) leach out during boiling—retain cooking water for soups or broths.

- Fat-soluble vitamins (A, E) withstand light cooking better; pair with healthy fats for absorption.

- Avoid frying, which destroys most vitamins due to high heat. Opt for grilling or roasting instead—delicious and nutrient-friendlier.

In summary: Gentle methods and proper storage ensure you enjoy vegetables' full nutritional benefits.
