DAIRY

DAIRY contains both protein and fat. Hard cheeses, such as parmesan, have one of the highest protein contents — 35g per 100g, compared to 16g in feta. Do remember that cheese is calorific so don’t eat too much.

Yoghurt is a great option as a pudding but opt for a natural full-fat version and add your own fruit. Low-fat fruit yoghurts can contain up to three times as much carbohydrate as full-fat Greek yoghurt.

In the early days Dr Unwin worried about how consuming full-fat dairy and lots of eggs would affect his patients’ cholesterol and other blood fat levels, so he did hundreds of blood tests. He has data on more than 150 patients who actually show average improvements in these levels, the opposite of what he expected, and he is planning to publish these findings.
