入门技巧

如果上面的内容对你来说太多、太新颖，请不要担心。这些现在在你看来极具挑战性的事情，再过几周你做起来就会像呼吸一样自然。

你可以从观察每餐的情况、实施餐盘法做起。

你每餐的宏量营养素搭配均衡吗？

大部分时候，你的餐食中都有蔬菜（搭配油脂）吗？

你用充足的高蛋白质食物来搭配高碳水化合物食物了吗？

你有没有摄入足量的包括动物脂肪在内的健康脂肪？

优先在餐食中纳入更多的天然食物，减少食用加工食品和含糖食品。

接下来，有意识地注意身体发出的饥饿信号和饱食信号。在进餐前、进餐期间、进餐快结束时和两餐之间留心身体的感觉。这是研究食物对身体的影响，试验哪些食物适合你、哪些食物不适合你的好机会。这是一个自我探索的过程。请把它想象成一个实验，而不是一次考试。

在尝试的过程中，你需要学习、记录并不断调整。当你发现什么食物不适合自己的时候，你就知道什么更适合自己了。孕期你的身体在不停地变化，所以你一定要对自己的饥饿水平、食量、进食时间的变化抱持开放的态度。

在下一章，我将详细介绍哪些食物对宝宝的生长发育尤为重要。
