Asparagus is s spring vegetable that's packed with nutrition. When you buy asparagus, either fresh from the farmers' market or grocery store, it's best to eat it right away. Asparagus pairs nicely with lots of other spring vegetables and flavors—think peas, garlic or new potatoes. 1 cup of cooked asparagus has 40 calories, 4 grams of protein, 4 grams of fiber and 404 milligrams of potassium. Potassium is good for blood pressure and asparagus also contains asparaptine, which helps improve blood flow and in turn helps lower blood pressure. If you need more reasons to enjoy this yummy vegetable read on to see some surprising reasons it's so good for you.
1. It’s Loaded with Nutrients
Asparagus is a very good source of fiber, folate, vitamins A, C, E and K, as well as chromium, a trace mineral that enhances the ability of insulin to transport glucose from the bloodstream into cells. That's good news if you're watching your blood sugar.
2. It Can Help Fight Cancer
This herbaceous plant—along with avocado, kale and Brussels sprouts—is a particularly rich source of glutathione, a detoxifying compound that helps break down carcinogens and other harmful compounds like free radicals. This is why eating asparagus may help protect against and fight certain forms of cancer, such as bone, breast, colon, larynx and lung cancers.
3. Asparagus Is Packed with Antioxidants
It's one of the top ranked fruits and vegetables for its ability to neutralize cell-damaging free radicals. This may help slow the aging process and reduce inflammation.
4. Asparagus Is a Brain Booster
Another anti-aging property of this delicious spring veggie is that it may help our brains fight cognitive decline. Like leafy greens, asparagus delivers folate, which works with vitamin B12—found in fish, poultry, meat and dairy—to help prevent cognitive impairment. In a study from Tufts University, older adults with healthy levels of folate and B12 performed better on a test of response speed and mental flexibility. (If you’re 50-plus, be sure you’re getting enough B12: your ability to absorb it decreases with age.)
5. It's a Natural Diuretic
It contains high levels of the amino acid asparagine, which serves as a natural diuretic, and increased urination not only releases fluid but helps rid the body of excess salts. This is especially beneficial for people who suffer from edema (an accumulation of fluids in the body's tissues) and those who have high blood pressure or other heart-related diseases.
And finally, to answer a question I often get regarding why eating asparagus causes a strong urinary odor: asparagus contains a unique compound that, when metabolized, gives off a distinctive smell in the urine. Young asparagus contains higher concentrations of the compound so the odor is stronger after eating these vernal shoots. There are, however, no harmful effects, either from the sulfuric compounds or the odor! While it is believed that most people produce these odorous compounds after eating asparagus, few people have the ability to detect the smell.
The most common type of asparagus is green, but you might see two others in supermarkets and restaurants: white, which is more delicate and difficult to harvest, and purple, which is smaller and fruitier in flavor. No matter the type you choose, asparagus is a tasty, versatile vegetable that can be cooked in myriad ways or enjoyed raw in salads.
