2. May 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.

4. May be 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 reduce the risk of cognitive impairment. If you're 50-plus, be sure you're getting enough B12, as your ability to absorb it decreases with age. Learn about anti-aging foods with our best foods to help keep your brain young.

Asparagus contains high levels of amino acid asparagine, which serves as a natural diuretic, increasing urination and helping the body to get rid of excess salts. This is especially beneficial for people suffering from edema (an accumulation of fluids in the body's tissues) and those with high blood pressure or other heart-related diseases.

Potential Side Effects

Have you wondered why eating asparagus causes a strong urinary odor?

These vernal shoots contain a unique compound, asparagusic acid, that, when metabolized, gives off a distinctive smell in the urine. Young asparagus contains higher compound concentrations, so the odor is stronger after eating them. Rest assured that there are no harmful effects from the sulfuric compounds or the odor! While it is believed that most people produce these odorous compounds after eating asparagus, few people can detect the smell.

Asparagus Varieties

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.
