Although some guys aren't opposed to smoking some weed, most wouldn't think of eating one. It's a shame, really, since a succulent weed named purslane is not only delicious but also among the world's healthiest foods.
Of course, there are many superfoods that never see the inside of a shopping cart. Some you've never heard of, and others you've simply forgotten about. That's why we've rounded up the best of the bunch. Make a place for them on your table and you'll instantly upgrade your health -- without a prescription.
These grungy-looking roots are naturally sweeter than any other vegetable, which means they pack tons of flavor under-neath their rugged exterior.
Why they're healthy: Think of beets as red spinach. Just like Popeye's powerfood, this crimson vegetable is one of the best sources of both folate and betaine. These two nutrients work together to lower your blood levels of homocysteine, an inflammatory compound that can damage your arteries and increase your risk of heart disease. Plus, the natural pigments -- called betacyanins -- that give beets their color have been proved to be potent cancer fighters in laboratory mice.
How to eat them: Fresh and raw, not from a jar. Heating beets actually decreases their antioxidant power. For a simple single-serving salad, wash and peel one beet, and then grate it on the widest blade of a box grater. Toss with 1 tablespoon of olive oil and the juice of half a lemon.
You can eat the leaves and stems, which are also packed with vitamins, minerals, and antioxidants. Simply cut off the stems just below the point where the leaves start, and wash thoroughly. They're now ready to be used in a salad. Or, for a side dish, sauté the leaves, along with a minced clove of garlic and a tablespoon of olive oil, in a sauté pan over medium-high heat. Cook until the leaves are wilted and the stems are tender. Season with salt and pepper and a squeeze of lemon juice, and sprinkle with fresh Parmesan cheese.
Absent from most American kitchens, this cruciferous vegetable is a major player in European and Asian diets.
Why it's healthy: One cup of chopped cabbage has just 22 calories, and it's loaded with valuable nutrients. At the top of the list is sulforaphane, a chemical that increases your body's production of enzymes that disarm cell-damaging free radicals and reduce your risk of cancer. In fact, Stanford University scientists determined that sulforaphane boosts your levels of these cancer-fighting enzymes higher than any other plant chemical.
How to eat it: Put cabbage on your burgers to add a satisfying crunch. Or, for an even better sandwich topping or side salad, try an Asian-style slaw. Here's what you'll need:
4 Tbsp peanut or canola oil
Juice of two limes
1 Tbsp sriracha, an Asian chili sauce you can find in the international section of your grocery store
1 head napa cabbage, finely chopped or shredded
1/4 cup toasted peanuts
1/2 cup shredded carrots
1/4 cup chopped cilantro
Whisk together the oil, lime juice, and sriracha. Combine the remaining ingredients in a large mixing bowl and toss with the dressing to coat. Refrigerate for 20 minutes before serving. The slaw will keep in your fridge for 2 days.
Guava is an obscure tropical fruit that's subtly acidic, with sweetness that intensifies as you eat your way to the center.
