The obvious distinction between the two is the color. Green asparagus has chlorophyll, a pigment that makes it green, while white asparagus doesn't. This is due to how they're grown: Green asparagus is grown in the sunlight, so it produces chlorophyll. White asparagus is covered, so it doesn't produce chlorophyll.

The white stalks also have a more mild taste. Green asparagus can be described as having a grassy or earthy taste, so if you don't really like it, give white asparagus a try.

Despite their differences in appearance and flavor, both white and green types of asparagus have a similar nutrition profile and health benefits.

One cup of cooked asparagus provides 76 percent of your daily value for vitamin K, according to the USDA. A diet rich in vitamin K is linked to lower rates of heart disease, according to Harvard Health Publishing.

People with high intakes of vitamin K were observed to have a 21 percent lower risk of being hospitalized for heart disease, according to an August 2021 study in the Journal of the American Heart Association.

Summary

Green asparagus has more antioxidants than white, but both are heart-healthy and great sources of fiber, vitamin K and other nutrients. While green asparagus is more common, white asparagus has a milder taste and is a fun way to mix things up.
