What are superfoods?
Superfood is a rather new and quite trendy term, which refers to foods that carry plenty of nutritional benefits, while also having less calories. Some consider that this is only marketing, while many say that they are the key to a healthy life. So, let’s see what superfoods are and why consuming them is beneficial.
Superfoods are healthy, nutrient-rich foods. Nevertheless, there is no precise definition to what a superfood is, and there are no defined criteria as to what can and what can’t be a superfood.
Superfoods contain a multitude of valuable nutrients, such as protein, vitamins, minerals, enzymes, antioxidants, good fats, essential fatty acids, amino acids, and phytochemicals (chemicals present in plants, responsible for their deep colors and smell).
What makes them superfoods?
Although there is no rule to tell which foods can and which can’t be superfoods, some of them make the superfood list because they have constituents with extraordinary health benefits, which are good for our health by themselves, too, but combined they make for an exceptional source of nutrients. These foods are usually especially rich in vitamins, minerals, and trace elements, which contribute to the prevention of numerous illnesses and can help us improve and maintain our overall health.
Aside from being a great source of nutrients, another great advantage of superfoods is that they are much more accessible than we’d think, especially in summer, when there are so many seasonal fruits and vegetables for us to choose from every day. They are not capable of making miracles happen, but they definitely help prevent illnesses, as they strengthen our health.
Why consume superfoods?
Because one food can’t provide all the necessary nutrients our body needs, having a diverse diet is the best way for us to give our body as many nutrients as possible. Superfoods contain many essential nutrients, and in a larger amount than most fruits and vegetables alone.
Moreover, most superfoods are a great source of antioxidants, meaning they can boost our immunity, protect our cells from the negative effects of oxidative stress, and have anti-cancer properties.
In the following, we have selected 5 popular and easily obtainable superfoods:
