Dried fruits are nutritionally higher in energy, relatively higher than rice and fruits. Because 1g of fat produces 9kcal of calories, 1g of protein and 1g of carbohydrates produces 4kcal of calories, and 1g of wine normally produces 7kcal of calories. So from this point of view, the fat content is relatively high in dried fruit 1g of fat produced energy, than 1g of ethanol, which is the energy produced by alcohol, so although dried fruit contains rich, good fatty acids, but also some trace elements, but in the process of eating must be taken into account is a high-energy food. If open to eat, such as a night to eat half a packet or a packet of melon seeds, or eat a large amount of walnuts, pistachios, hazelnuts, are likely to cause excessive energy intake, which in turn may cause a high incidence of chronic metabolic diseases represented by obesity. So dried fruits must be eaten in strictly controlled amounts because of the relatively high calorie content.
