Vegetables are excellent sources of vital vitamins and minerals.
- Vitamin A: Found abundantly in carrots, sweet potatoes, and spinach, vitamin A supports vision, immune function, and cell growth.

Fiber: Promoting Digestive Health and Beyond
Dietary fiber, abundant in vegetables, plays a crucial role in maintaining a healthy digestive system.

Antioxidants: Fighting Free Radicals
Vegetables are rich in antioxidants, compounds that protect our cells from damage caused by free radicals.
- Reduce Inflammation: Antioxidants help neutralize free radicals, reducing inflammation throughout the body.
- Protect Against Chronic Diseases: Studies have shown that diets rich in antioxidants can help protect against chronic diseases like heart disease, cancer, and Alzheimer’s disease.

Keeping Your Greens Fresh: Proper Vegetable Storage
Proper storage is crucial to preserving the freshness and nutritional value of your vegetables.
General Storage Tips

- Refrigerate Promptly: Store most vegetables in the refrigerator, ideally in the crisper drawer, to maintain their freshness.
- Don’t Wash Before Storing: Washing vegetables before storing can promote mold growth. Wash them only when you’re ready to use them.

Specific Vegetable Storage
- Leafy Greens: Store in a breathable bag or container lined with a paper towel in the refrigerator.
- Root Vegetables: Store in a cool, dark, and dry place, such as a pantry or basement.
- Tomatoes: Store at room temperature until ripe, then refrigerate to slow down ripening.
- Onions and Garlic: Store in a cool, dry, and well-ventilated place.
Extending Shelf Life
- Blanching and Freezing: Blanch vegetables for a few minutes in boiling water, then plunge them into ice water to stop the cooking process. This helps preserve their color, texture, and nutrients before freezing.
- Pickling: Pickling vegetables is a great way to preserve them for longer periods.
- Dehydrating: Dehydrating vegetables removes moisture and extends their shelf life.
