They are small and look harmless, but nuts contain a lot of hidden fat.
Answer this, how many grams of fat are there in 100 grams of macadamia nuts? Guess about 40 or 50 grams? Wrong! There are 73 grams--and that's a lot for something so little.
Other types of nuts that put up a good fight for the fat trap title: Brazil nuts weigh in with 67grams of fat, hazelnuts and peanuts are at the 60 and 50 grams mark, respectively. The light-weight of the group are cashews, which contain only 40 grams.
The best advice we can give is to buy nuts in their shells. When you buy roasted nuts out of their shells they will usually have been cooked in fat.
