Arugula is a flavourful, oak-shaped leaf with a peppery taste. Known as 'Rocket' in some parts of the world, arugula adds a powerful health boost to any menu choice. Easily grown at home, this leafy green contains about 5 calories per cup meaning it would take 20 cups of arugula to get the same calories in just a ¼ cup of granola.
The fibre in arugula helps promote digestive regularity, keeps your tummy happy and leaves you feeling full longer so you resist other fatty foods. It also helps to lower cholesterol, balance blood sugar and reduce the risk of heart disease. (1)
Here are five more reasons to add rocket to your meals:
1. Arugula is a detoxifying, cancer-fighting superfood: Arugula is a member of the brassica family of vegetables called cruciferous – this group is known for its nutritional powerhouses broccoli, kale and cabbage. This family of vegetables is high in fibre and antioxidants, but they’re also rich in compounds known as glucosinolates (2), which studies show may reduce the risk of developing lung, colorectal, breast, prostate, and pancreatic cancer. (3)
2. Arugula has high levels of chlorophyll: Chlorophyll can help to prevent DNA and liver damage from aflatoxins (4) - carcinogenic substances (5) produced by the mould sometimes found in corn, peanuts and some tree nuts. To preserve the chlorophyll in arugula – eat it raw. It tastes great in a salad!
3. Arugula promotes bone health: It contains eight times more calcium than iceberg lettuce as well as vitamin K (6), which is important for the absorption of calcium into the bones and teeth. Vitamin K also plays a role in the prevention of heart disease. (7) Plaque that forms inside the linings of the arteries can be partly related to calcium that is not taken up by the bones and teeth. This important vitamin can also help to keep this calcium going to the bones where it belongs!
4. Eating arugula will help to reduce chronic inflammation: Arugula contains indole-3-carbinol and isothiocyanates. Both of these bioactive compounds have been shown to suppress the production of inflammatory mediators. (8)
5. Eating arugula can protect the ageing brain and cognitive decline: Arugula is high in most of the B vitamins but contains especially high amounts of folate. In high functioning older adults, low levels of folate have been shown to be a risk factor for cognitive decline. (9)
