People are often reluctant to include nuts in their diet as they believe them to be high in cholesterol, however they also contain omega 6 and 3 fats and good levels of minerals and some vitamins, so they’re a really good addition to a healthy diet. Of course, nuts covered in salt and sugar are to be avoided, but you can make your own tasty snack by sprinkling with soy sauce and toasting them lightly under a medium grill.
