Vegetables are an essential part to any healthy diet, but it's always a good idea to rotate what you eat and discover new flavors, textures and nutrients that Mother Nature has to offer. Unfortunately, common knowledge surrounding vegetables is limited, leaving many of us out of the loop on a bounty of delicious produce. Here are 5 healthy vegetables you don't want to miss for both their taste and nutrition!

1. Celeriac


Celeriac is a root vegetable that is widely cultivated in Europe and the Mediterranean, but not so popular and readily available in the US. It may very well be the vegetable world's ugliest duckling, but it is what is on the inside that counts. In one cup of celeriac (otherwise known as celery root, turnip-rooted celery or knob celery), there are 66 calories, 468 milligrams of potassium, 2.8 grams of dietary fiber, 2.3 grams of protein, 20% of the RDA of vitamin C, 15% of the RDA of vitamin B-6 and a good amount of calcium, iron and magnesium.

2. Kai-Lan


Also known as "Chinese Broccoli" or "Chinese kale", Kai-lan is a dark green leaf vegetable that has thick steams, blue-green leaves and flower heads akin to those of broccoli. In one cup, there are 20calories, 230 milligrams of potassium, 2.2 grams of dietary fiber, 1 gram of protein, 41 percent of the RDA of vitamin C, 28 percent of the RDA of vitamin A and a good amount of calcium, iron, vitamin B-6 and magnesium.

3. Kohlrabi


Kohlrabi is commonly eaten in German-speaking countries and is also featured in northern Indian cuisine. It is also called "German turnip" or "turnip cabbage". It has a similar taste and texture to that of broccoli or a cabbage heart but it is milder and sweeter. While they may appear both in green and purple, the edible parts are almost always pale yellow. In one cup, there are 37 calories, 473 milligrams of potassium, 3.9 grams of dietary fiber, 2.3 grams of protein, 139 percent of the RDA of vitamin C, 10 percent of the RDA of vitamin B-6 and plenty of calcium, iron and magnesium.

In 100 grams, oca offers more than 60 percent of the RDA of vitamin C, 12 percent of the RDA of zinc, 55 percent of the RDA of vitamin B-12, 8 grams of dietary fiber and only 30 calories.
