Food is paramount to the people, the kidneys are the foundation of innate nature, the spleen is the foundation of acquired nature, and the spleen and stomach are interdependent. A person's spleen and stomach function is poor, their ability to absorb and transport food is reduced, and their physical health is not good.

People with poor spleen and stomach can be seen at a glance from their appearance. We often encounter such people in clinical practice.

Pale complexion, lips without any luster, pale or blackish;

Some are too thin and weak, as if they can be blown down by a gust of wind;

Some are very overweight, appearing to have a large physique, but in reality, they are just hollow and not at all sturdy;

Speaks weakly, lacks energy, is listless, young but prematurely aged, and completely unable to muster strength.
民以食为天，肾为先天之本，脾为后天之本，脾胃一体互为表里。一个人的脾胃功能差了，吸收食物，运化食物的功能变差，体能健康各种不好。

脾胃不好的人，从外表上就基本一眼就能看出来。在临床中常碰到这样的人。

面色苍白，口唇没有一点光泽，苍白或者黑凝；

有的过于消瘦，弱不禁风，好像一阵风就能吹倒了；

有的很胖，看似体格庞大，实际上就是虚胖，一点都不结实；

说话有气无力，精神不振，无精打采，年纪轻轻却未老先衰，完全提不起气力。
