A simple case study of calories calculation

Hi, it's a frustrating yesterday as Blogger was down and my latest post was somehow missing until it appeared again after fixed. Well, hope similar incident is not happening again.
Lets take an example for calorie calculation of snack that I collected from a patient. She took a piece of chocolate which contains 135 Kcal, a cup soy milk contains roughly 150 Kcal and one small box of raisin with 45 Kcal with dietary fiber 1g. The total calories for her snack would be around 330 Kcal. From this example, we should determine the balance of macronutrients distribution towards a food choice. We know that chocolate contains high amount of saturated fat and sugar, so it is not desirable for daily consumption, I recommend to only take once or twice in a month.While soy milk is a type of drink which is high in protein, a type of good source of plant protein, suitable for daily consumption for normal people. If you are a diabetes patient, you might need to be aware on the sugar level in the food label of your snack. The last item- raisin which is high in dietary fiber is suggested to take in daily in order to achieve 20-30g dietary fiber in a day. Thus, from my explanation, we can determine which type of foods that can provide benefits to our body rather than just depends on calories counter, others factor are needed to be consider (such as medical history, family medical history (gene) and your current health condition).

现在,就让我来拿一位病人的零食习惯举个例子来计算摄入的卡路里吧!这包括一块巧克力,根据食物标签,含有大约135卡路里,豆浆含有大约150卡路里,小盒葡萄干含有45卡路里和1g纤维。所以,她的零食总热量大约330卡路里。从这,我们应该平衡选择对身体健康的各种营养素。当然我们知道,巧克力中含有饱和脂肪和高糖量,所以不适合用于每天食用,应控制至一个月一次而已。至于豆浆是一种含丰富蛋白质的饮料,是一种很好的植物蛋白来源,适合我们每天饮用的。如果你是一个糖尿病患者,那么你需要留意食品标签以了解糖份水平。最后一个是葡萄干是含有高膳食纤维的,所以是建议食用以达到在日常生活中应摄取2030克的纤维。因此,在考虑食物选择时,我们需要确定哪些类型的食物可以给我们提供益处,而不是仅仅依赖于卡路里,其他因素也需要加以考虑(如病历等)
