Celery isn’t a classic diet food without reason. 1 full cup of celery contains only 16 calories (9).
It actually requires more calories to digest than what it contains. Best of all, celery doesn’t lose its rich content of vitamin K, A, C, folate, potassium, and antioxidants after being cooked (10).
Fresh celery juice even has the ability to reduce the activity of inflammatory proteins tumor necrosis factor alpha (TNF-A) and nuclear factor-kappa B (NF-KB) (11). Celery also contains plenty of fiber and water, which improves digestion and hydration. However, celery has much more sodium than other vegetables, so sodium-conscious individuals might want to avoid eating too much celery.
4. Brussels Sprouts
These notoriously avoided vegetables only contain 38 calories per cup. Best of all, they supply 125% of your daily value of vitamin C and 195% of your daily value of vitamin K. They’re also surprisingly high in protein (12).
As a cruciferous vegetable, Brussels sprouts contain glucosinolates, which lower the risk of lung and colorectal cancer in some individuals (13).
Properly cooked, Brussel sprouts have a sweet, slightly nutty and subtlety bitter taste. They make a great side dish when baked to a crisp and combined with pecans, goat cheese, and dried cranberries (14).
