They are all quite high, but the nutritional value is different. It depends on how much you eat. On the premise of the same weight, the calories are basically the same. If everyone can only eat less than 10g, there is no big problem. If you eat 500g at a time, everything is easy to gain weight. Eating 500g apples is basically equivalent to a bowl of rice. In fact, the root of obesity is oil and sugar. Eating dark chocolate properly can protect the heart, but many chocolates in China don't have much pure chocolate, but they contain a lot of trans fat. If so, I suggest you eat some nuts, but if nuts are fried and refined, they are not healthier and more nutritious. It is best not to exceed 30 grams at a time.
