For Native Americans, zucchini were considered as one of the "three sisters" along with corn and beans. Zucchini,also known as courgettes contain very few calories and have a high water content,which makes them a dieter's friend. They provide useful amounts of immune system boosting vitaminC,and significant levels of potassium,which is key to controlling blood pressure. The soluble fibre in the skin slows down digestion,and so stabilises blood sugar and insulin levels. Soluble fibre also helps prevent constipation and relieves irritable bowel symptoms. Some of the benefits of raw or grilled zucchini come from the squash’s magnesium content. Magnesium plays a central role in muscle contraction-the mineral supports the function of proteins abundant in your muscle fibres. Magnesium also makes up a component of bone mineral,and consuming enough of the vitamin helps maintain strong bones. Served raw,sliced zucchini pairs well with nutritious dips,such as hummus or guacamole. Grill your zucchini with healthy flavourings,such as coconut oil,pepper and a small amount of salt,or marinate in balsamic vinegar before grilling. They make the basis for an interesting veggie main course grated in a fritter,with lots of chopped dill.
