There are foods that have been recommended as healthy, beneficial and generally good for us. And while many are on the generally approved list of foods to eat on the ketogenic, low carb/high fat (LCHF) diet, many are not. To people who have read a bit about what to avoid when keeping carbohydrates very low, many of the foods not on the approved list will be of no surprise: grains, even so-called 'healthy whole grains, milk (although heavy cream is allowed), potatoes, etc., But a couple of food groups that aren't on the allowed list raise the eyebrows of some. No fruit? And what about nuts? Aren't those foods super good for you?
