Hello, I'm a nutrition expert with a keen interest in the caloric content of various foods and snacks. When it comes to M&M's, the caloric content can vary slightly depending on the size and specific type of M&M, as well as whether they are plain or peanut-based.

For a standard M&M, which is about 0.54 grams, there are approximately 3 calories. However, this is just an estimate, as the exact caloric content can differ. If you're looking at a serving size, which is typically around 28 grams for a small bag, that would equate to about 168 calories.

Now, let's translate that into Chinese:

你好，我是一位对各种食物和零食的热量含量有浓厚兴趣的营养专家。谈到M&M's，其热量含量可能会因M&M的大小、特定类型以及它们是普通型还是花生型而略有不同。

对于一个标准大小的M&M，大约是0.54克，大约含有3卡路里的热量。然而，这只是一个估计值，因为确切的热量含量可能会有所不同。如果你看的是一份的量，通常一小袋大约是28克，那么大约相当于168卡路里的热量。

You'll get just three calories from a lone milk chocolate M&M's. If you have one of the other types though, you'll wind up with three to four times as many calories. A single peanut, crispy or peanut butter-filled M&M's each provide between 10 and 12 calories per piece.read more >>
