Protein is essential for a healthy immune system and for keeping your heart, brain and skin in tip-top shape. It also can play a role in controlling appetite and enhancing muscle growth.
蛋白质对于健康的免疫系统以及保持心脏、大脑和皮肤处于最佳状态至关重要。它还可以起到控制食欲和促进肌肉生长的作用。
Generally speaking, though, you can break protein powders into two types: animal and plant. Popular animal protein powders include whey and casein.
不过，一般来说，你可以将蛋白粉分为两种类型：动物蛋白粉和植物蛋白粉。流行的动物蛋白粉包括乳清和酪蛋白。
Whey protein is a popular choice due to its high concentration of leucine, an amino acid that helps build and maintain muscle mass.
乳清蛋白是一种受欢迎的选择，因为它含有高浓度的亮氨酸，亮氨酸是一种有助于建立和维持肌肉质量的氨基酸。
On the other hand, pea, soy, and hemp are common plant-based options.
另一方面，豌豆、大豆和大麻是常见的植物性蛋白。
They're good for people with lactose intolerance or sensitive stomachs, and they may have a lower environmental footprint compared to animal-based proteins.
它们适合乳糖不耐受或胃敏感的人，与动物蛋白相比，它们对环境的影响可能更小。
When shopping for the protein powder that's right for you, look out for these things:
在购买适合您的蛋白粉时，请注意以下几点：
One, choose a protein powder that contains at least 20 grams of protein per scoop.
第一，选择每勺至少含有20克蛋白质的蛋白粉。
Two, be mindful of added ingredients like sugars, artificial sweeteners and fillers.
第二，注意添加的成分，如糖、人工甜味剂和填充剂。
And three, look for a certification on the label like informed Sport or NSF, to ensure it contains what it advertises and is free of banned substances.
第三，查看标签上的认证，如Informed Sport或NSF，以确保其含有广告宣传的内容且不含违禁物质。
Just remember that while protein powder supplements can be a part of a healthy diet, they shouldn't define it.
请记住，虽然蛋白粉补充剂可以成为健康饮食的一部分，但它们不应该定义健康饮食。
Whole foods sources offer a spectrum of nutrients that powders can't replicate.
全食来源提供蛋白粉无法复制的一系列营养成分。
So whether you prefer a shake or a balanced meal, prioritize what nourishes your body and supports your goals.
因此，无论您喜欢奶昔还是均衡膳食，请优先考虑滋养身体并支持目标的食物。
