What is actually in peanut butter?
花生酱有哪些成分？

Peanut butter is a relatively uNPRocessed food comprising peanuts that are ground into a paste. However, different commercial brands of peanut butter sometimes add ingredients to this including sugar, vegetable oils and even trans fat. If the brand is just ground peanuts then the health effects of peanut butter should be identical to just eating peanuts which means high protein, healthy fats and fiber.
相对来说，花生酱是一种未加工的食品，由研磨成糊状的花生组成。然而，不同品牌的花生酱有时会含有添加成分，包括糖、植物油，甚至还包括反式脂肪。如果该品牌花生酱的成分只有磨碎的花生，那么其营养成分应与直接吃花生差不多：高蛋白、健康脂肪和纤维。

Calories
热量

One of the reasons that people believe peanut butter is unhealthy is because it is high in calories, but the quality of the calorie intake determines whether it is good or bad. Two tablespoons of peanut butter contains 188 calories, 8g protein, 6g carbohydrate and 16g fat (if not mixed with additives).
人们认为花生酱不健康的其中一个原因就是花生酱热量高，但卡路里摄入量的质量才是决定其好坏的因素。两茶匙花生酱含有188卡、8克蛋白质、6克碳水化合物和16克脂肪（如果没有添加剂的话）。

Although 188 calories sounds a lot, and can account for nearly 10% of your daily intake, this is not necessarily bad. It's high fat content makes you feel satiated with fewer calories, thus meaning you will eat less throughout the day. Weight is dictated by calories in and calories out so a moderate amount of peanut butter certainly can fit into your daily food intake.
尽管188卡听起来很多，但它只占你每日摄入量的10%左右，并不算糟糕。花生酱脂肪含量很高，所以即使摄入的热量减少也会让你感到饱腹，也就意味着你会吃的更少。体重是由摄入的卡路里和排出的卡路里量所决定的，所以每天食用适量花生酱当然是没问题的。

Low fat
低脂

Alongside the caloric load, peanut butter's saturated-fat content is a concern for some people, particularly as it was considered a big cause of heart disease and was disparaged by the fat-loss community. Saturated fat is not as evil as it is made out and is actually beneficial to the production of testosterone and vitamin D.
除了热量，有些人还担心花生酱的饱和脂肪含量，尤其因为：饱和脂肪被认为是导致心脏病的主要原因，且被减肥群体所嗤之以鼻。饱和脂肪并不像人们所以为的那么糟糕。实际上，它有助于睾酮和维生素D的产生。
