Die 5 nahrhaftesten Gemüsesorten basierend auf Wissenschaft

Supermarkt Gemüse

Gemüse aller Farben ist reich an Vitaminen, Mineralien, Ballaststoffen und sekundären Pflanzenstoffen. Sie können nichts falsch machen, wenn Sie Ihrem Teller mehr bunte Produkte hinzufügen. Einige Gemüsesorten enthalten jedoch im Verhältnis zu den Kalorien mehr Nährstoffe, was sie sehr hilfreich für die Gewichtskontrolle und die Gesundheit macht.

Dr. Fuhrman, der Entwickler der Nutritious Diet, hatte die Idee des ANDI (Comprehensive Nutrient Density Index), um den Nährstoffgehalt von Obst und Gemüse im Verhältnis zu Kalorien zu quantifizieren. Anhand des ANDI-Scores übernahmen die Forscher die zeitaufwändige Aufgabe, 41 Obst- und Gemüsesorten nach Nährstoffdichte zu ordnen. Mal sehen, welche Produkte die Liste in Bezug auf die Nährstoffdichte pro Kalorie basierend auf den ANDI-Scores anführen.

Brunnenkresse

Brunnenkresse (100 % Nährstoffdichte)

Nach ANDI-Standards gehört Brunnenkresse zu den nährstoffreichsten Gemüsesorten pro Kalorie. Brunnenkresse ist ein dunkelgrünes Blattgemüse, das in kalten, klaren Bächen und Flüssen wächst und wegen seines würzigen Geschmacks roh oder gekocht genossen werden kann. Wenn Sie dieses grüne Blattgemüse jedoch roh essen, behalten Sie mehr Vitamin C. Brunnenkresse verleiht Salaten, Wraps und Sandwiches Geschmack. Neben Vitamin C ist Brunnenkresse auch reich an Vitamin K, das für die Blutgerinnung und Knochendichte wichtig ist, sowie Beta-Carotin, eine Vorstufe von Vitamin A, ein Antioxidans und entzündungshemmend.

Noch interessanter sind die Antioxidantien in Brunnenkresse, einschließlich Phenethylisothiocyanat (PEITC).Eine Studie fand heraus, dass die Antioxidantien in Brunnenkresse dies hemmten

DNS
DNA oder Desoxyribonukleinsäure ist ein Molekül, das aus zwei langen Nukleotidketten besteht, die sich zu einer Doppelhelix umeinander winden. Es ist das Erbgut des Menschen und fast aller anderen Organismen, mit genetischen Anweisungen für Entwicklung, Funktion, Wachstum und Fortpflanzung. Fast jede Zelle im menschlichen Körper hat die gleiche DNA. Die meiste DNA befindet sich im Zellkern (als Kern-DNA bezeichnet), aber kleine Mengen an DNA können auch in Mitochondrien gefunden werden (als mitochondriale DNA oder mtDNA bezeichnet).

Napa Cabbage

Chinese Cabbage (Nutrient Density Score 92%)

Chinese cabbage is also called Napa cabbage, and it’s a member of the Brassica family. This green, leafy veggie has long, pale green leaves with white ribs and a sweet flavor. Since it’s a cruciferous vegetable, like watercress and broccoli, it contains similar phytochemicals, some of which are being explored for potential anti-cancer benefits.

What you might not know about Chinese cabbage is it’s more nutrient dense than regular cabbage, offering more of certain vitamins such as vitamins C, K, and folate, a B-vitamin. Plus, it contains various antioxidants with anti-inflammatory activity, all for only 9 calories a cup.

To get the most vitamin C from Chinese cabbage, enjoy it raw in salads and sandwiches. If you prefer it cooked, add the chopped leaves or ribs to stir-fries with other Asian ingredients. Stir-fry recipes typically have a base of garlic and ginger, which work well with Chinese cabbage’s mild flavor. Add chicken, shrimp, or tofu for protein.

Swiss Chard

Swiss Chard (Nutrient Density Score 89%)

Swiss chard, also known as leaf beet, is a leafy green vegetable that belongs to the same family as beets. Its leaves have a mild flavor like spinach, but it has a slightly tougher texture that softens when you cook it. Swiss chard is a rich source of vitamin K, although it contains less vitamin C than the top two most nutrient-dense veggies, watercress, and Chinese cabbage, per calorie.

One downside is Swiss chard is high in oxalates. If you have a history of calcium oxalate kidney stones, it’s best to avoid Swiss chard since it can increase the amount of oxalates in your urine and boost the odds of kidney stones forming. Cooking Swiss chard reduces but doesn’t eliminate, oxalates.

Need a quick way to prepare it? Try sauteing Sauté Swiss chard in olive oil until just wilted (about 5 minutes). Season with salt and pepper to taste before serving.

Beet Greens

Beet Greens (Nutrient Density Score 87%)

Beet greens are the leaves of beets, colorful root vegetables that grow in the ground. Beet greens are like spinach in texture and taste but have a more intense flavor. You can enjoy these leafy greens raw in salads or cooked like spinach, Swiss chard, or other leafy greens. But like Swiss chard, they’re high in oxalates, so it’s best to cook them to reduce their oxalate content.

Enjoy beet greens cooked or steamed, and tossed with olive oil, lemon juice, or vinegar. You can also sauté them with garlic and onions for a flavorful side dish to add to your dinner plate.

Why are beet greens so nutrient-dense? With each bite, you get a healthy dose of vitamins A and C, but they also contain respectable quantities of minerals such as iron and zinc.

Bowl of Spinach

Spinach (Nutrient Density Score 86%)

Who isn’t familiar with the green, leafy vegetable known as spinach? It’s widely available and packed with nutrients such as vitamins A, C, and K, and like all leafy greens, an excellent source of fiber.

Like Swiss chard, beet greens, and spinach, spinach is also high in oxalates. If you have a history of calcium oxalate kidney stones, it’s safest to substitute a lower-oxalate green such as watercress or kale for spinach.

Spinach also contains compounds called thylakoids that have appetite-suppressing benefits. Plus, spinach is a rich source of lutein and zeaxanthin, carotenoids which may help prevent age-related macular degeneration (AMD) and cataracts, common causes of visual decline.

Leafy Greens Dominate the List

You may have noticed a trend. Leafy greens top the list of nutrient-dense foods per calorie. Another benefit of leafy greens is they’re high in natural nitrates, compounds that increase nitric oxide, a gas that helps open blood vessels. This enhances endothelial function, healthy blood vessel function that lowers blood pressure, and the risk of blood clots, another reason to add greens to your plate.

The Bottom Line

Leafy greens are nutrient-rich and lower in calories and top the list in terms of ANDI scores. Still, it’s smart to enjoy a wide array of non-starchy vegetables and fruits for optimal health. Almost all contain substantial quantities of potassium, a mineral and electrolyte that helps lower blood pressure. So, fill your grocery cart with fruits and vegetables in all colors of the rainbow, but don’t forget to add these five veggies with the highest ANDI scores.
