看看指甲，了解自己缺不缺蛋白质

If you're someone who feels amazing after leaving the salon with a fresh manicure, we get it. Perfectly painted nails and a little pampering can lift almost anyone into a brighter mood. But before you slather on polish to your always manicured nails, take a good hard look at your fingernails first because your fingernails can reveal surprising things about your health. Strong, well-rounded, and slightly pink nails are a sign of being in great health, according to Everyday Health. If this is not a description for your nails sans fresh polish, then it might be a clue to an underlying health-related issue.

如果你在美甲沙龙做完新指甲后感觉很棒，我们会理解。涂上完美的指甲，稍加呵护，几乎可以让任何人心情更愉快。但是，在你给你总是修剪整齐的指甲涂上厚厚的指甲油之前，先仔细看看你的指甲，因为你的指甲可以揭示你健康方面令人惊讶的事情。据《每日健康》报道，结实、圆润、略带粉红色的指甲是身体健康的标志。如果这不是指甲没涂指甲油·的描述，那么它可能是潜在健康相关问题的线索。

There is no need to panic. A lot of times, nail issues can be fixed with a balanced diet and a healthy lifestyle, per Healthline. The outlet claims that the addition of iron and biotin into your diet may be all that is needed for discolored nails, for example. Healthline also suggests adding more protein to your diet if your nails are giving you this specific sign.

没有必要惊慌。很多时候，根据Healthline，通过均衡的饮食和健康的生活方式可以解决指甲问题。例如，该网站声称，在饮食中添加铁和生物素就可以让指甲恢复色泽。Healthline还建议，如果你的指甲有特殊的症状，那么在你的饮食中添加更多的蛋白质。

Protein is essential to overall health — including fingernails

蛋白质对包括指甲在内的整体健康至关重要

If you notice your fingernails are dry and tend to break easily, then protein deficiency could be the clue! And If you think you might not be getting enough protein in your diet, then trust us, you are not alone. According to Healthline, approximately one billion people worldwide have a protein deficiency. A severe protein deficiency can cause your nails to appear and feel thin and brittle. Protein in our diet is what makes keratin, a structural protein that comprises most of our fingernails, per Healthline. So eating enough protein to help boost your keratin production is the key to strong, healthy fingernails. In addition to hair and nails, a more serious protein deficiency can lead to weaker bones and stunted growth in children.

如果你注意到你的指甲很干而且容易折断，那么可能是蛋白质缺乏!如果你认为你的饮食中可能没有摄入足够的蛋白质，那么相信我们，你并不孤单。根据Healthline的数据，全世界大约有10亿人患有蛋白质缺乏症。严重的蛋白质缺乏会导致你的指甲显得又薄又脆。饮食中的蛋白质是构成角蛋白的主要来源，角蛋白是一种构成我们大部分指甲的结构蛋白。因此，摄入足够的蛋白质来促进角蛋白的生成是强健、健康指甲的关键。除了头发和指甲，更严重的蛋白质缺乏症会导致儿童骨骼变弱和发育不良。

Medical News Today shares that consuming foods like lean meats, fish, eggs, and beans are all excellent protein sources to help you feel fuller longer, give you more energy, and, yes, keep your nails and hair from breaking. So before you head into the salon to pick your next color, take a good look at your nails. Because they might be a tell-tale sign that it's time to add more protein to your diet.

《今日医学新闻》分享了瘦肉、鱼、鸡蛋和豆类都是极好的蛋白质来源，可以帮助你保持更长时间的饱腹感，给你更多的能量，而且，如上，还可以防止你的指甲和头发断裂。所以，在你走进沙龙挑选下一种颜色之前，好好看看你的指甲。因为它们可能是一个信号，告诉你是时候在饮食中添加更多的蛋白质了。
