SUPERFOOD #1 Watercress
Nutrition Score: 100
The top dog, the unrivaled champion, the chairman of the cutting board, watercress may also be the closest thing yet to a true anti-aging food. Gram for gram this mild-tasting and flowery-looking green contains four times more beta carotene than an apple, and a whopping 238 percent of your daily recommended dose of vitamin K per 100 grams — two compounds that keep skin dewy and youthful. The beauty food is also the richest dietary source of PEITC (phenylethyl isothiocyanate), which research suggests can fight cancer. Results from an eight-week trial published in the American Journal of Clinical Nutrition suggest daily supplementation of 85 grams of raw watercress (that’s about two cups) could reduce DMA damage linked to cancer by 17 percent. Exposure to heat may inactivate PEITC, so it’s best to enjoy watercress raw in salads, cold-pressed juices, and sandwiches.
