A very popular “super food”, goji berries have an embarrassing number of positive factors. There is some evidence to show they boost immune response, increase brain activity, lower cancer and heart rate problems and extend your life. Vitamin A, B2, C, antioxidants and iron, alongside micronutrients like selenium, make goji berries a remarkably healthy choice. Naturally, they’re full of sugar, so you can’t eat too many, but the health benefits are worth a daily intake. Did we mention they are delicious? Put them in your breakfast cereal, add them to a smoothie, stick a bag in your pocket and have a virtuous snack at lunchtime.
