Onions are surprisingly high in nutrients – including B vitamins, potassium, and a high amount of vitamin C.
Other promising studies have shown that onions may lower blood sugar levels, boost bone mineral density, and fight against the growth of harmful bacteria, to name just a few!
Sweet potatoes are very high in fiber, vitamins, minerals and antioxidants. Additionally, they’re full of beta-carotene, which converts to vitamin A and is extremely beneficial for eye health and also for supporting the immune system.
Studies have shown that they may help with digestive health too due to the amount of fiber they contain, as well as promoting a healthy brain.
Carrots are another excellent source of beta-carotene, which converts to vitamin A. They also contain high amounts of other nutrients such as biotin, vitamin K, potassium and vitamin B6.
As mentioned, vitamin A is very beneficial for eye health, as well as supporting the immune system. They have also been linked with helping to lower cholesterol levels, as well as aiding in weight loss.
Perhaps the most versatile vegetable known to man, and my personal favourite – the potato is actually full of nutrients, largely found in the potato skin.
They are a very good source of antioxidants, which help the body to fight diseases, as well as containing resistant starch which has been linked to many health benefits including reducing insulin resistance, leading to better blood sugar control. This type of starch has also been linked to feeding good bacteria in the gut, thus having a positive effect on digestive health.
