Watercress tops list of ‘powerhouse fruits and vegetables’, Study

Despite its rapid rise up the ranks of so-called superfoods in recent years, kale does not even make the top 10 “powerhouse fruits and vegetables”, according to a new study.

Rather, watercress was the unlikely winner, packing a peppery punch with its cross-section of critical nutrients.

The research, from the United States of America’s William Paterson University, rated 47 different fruits and vegetables on their compilation of fibre, calcium, protein, potassium, and vitamins, among other things.

Researchers developed and validated a classification scheme defining PFV as foods providing, on average, 10 per cent or more daily value per 100 kcal of 17 qualifying nutrients.

Of the 47 foods studied, 41 satisfied the powerhouse criterion and were more nutrient-dense than were non-PFV, providing preliminary evidence of the validity of the classification scheme.

The researchers’ top 30 is as follows:

1. Watercress // 2. Chinese cabbage // 3. Chard // 4. Beet greens // 5. Spinach // 6. Chicory // 7. Leaf lettuce // 8. Parsley // 9. Romaine lettuce // 10. Collard greens // 11. Turnip greens // 12. Mustard greens // 13. Endives // 14. Chives // 15. Kale // 16. Dandelion greens // 17. Red peppers // 18. Rocket // 19. Broccoli // 20. Pumpkin // 21. Brussels sprouts // 22. Spring onions // 23. Kohlrabi // 24. Cauliflower // 25. Cabbage // 26. Carrots // 27. Tomatoes // 28. Lemons // 29. Iceberg lettuce // 30. Strawberries

The six that didn’t make the cut were raspberries, tangerines, cranberries, garlic, onions, and blueberries.
