Choosing the right foods for a balanced diet can often feel like a puzzle. But a recent study conducted by researchers at William Paterson University in New Jersey has identified one food that stands out for its exceptional nutritional density. According to the research, this food provides 100% of your daily essential vitamins and minerals in just a 100-gram portion. So, what is this powerhouse ingredient?
The Must-Have Watercress: The Ultimate Superfood
Watercress, with its small, elongated green leaves, might not be the first vegetable that comes to mind when you think of healthy foods, but it deserves to be at the top of your grocery list. This leafy green is low in calories but packed with nutrients. In fact, watercress scored a perfect 100 for nutritional density, meaning a 100-gram serving fulfills all of your body’s daily requirements for essential nutrients. Among these nutrients are potassium, fiber, protein, calcium, iron, and an impressive array of vitamins—A, B6, B12, C, D, E, and K.
The Benefits of Watercress
Beyond its nutritional value, watercress is also known for its detoxifying, antioxidant, and diuretic properties. Its slightly bitter, peppery taste—similar to mustard—makes it a versatile ingredient in the kitchen. You can enjoy it fresh in salads, sautéed, blended into soups, or added to various dishes to enhance flavor. Its versatility makes it easy to incorporate into a variety of meals, from sandwiches to soups to smoothies.
How to Choose and Store Watercress
Watercress is available year-round and is primarily grown in regions like ÃŽle-de-France, Aquitaine, and Nord-Pas-de-Calais in France. It’s typically sold in bunches, ensuring product traceability. When selecting watercress, look for bright green, firm leaves that are free from blemishes. Avoid watercress with dull leaves, as it may be wilted or past its prime. For the best taste and texture, consume it within two days of purchase to enjoy its full freshness and crunch.
Why Add Watercress to Your Diet?
With only 21 calories for a large handful (about 80–100 grams), watercress is a nutrient-dense, low-calorie addition to any diet. It’s affordable, typically costing around 2 euros per bunch, and can transform even the simplest dish into a nutritional powerhouse. Due to its high vitamin content, it rivals foods like oranges and lemons when it comes to vitamin C.
Incorporating watercress into your diet is an easy and effective way to maximize your intake of essential nutrients. Whether you enjoy it in a salad, a soup, or as a side dish, watercress deserves its place as one of the healthiest foods on the planet. Try adding it to your next meal—you’ll be doing your body a favor while adding a delightful new flavor to your dishes!
