Could Your “Healthy” Foods Be Draining Your Vital Energy?

Why Eating the Wrong Foods Can Quietly Drain Your Gut Power

Article Summary

Many people believe that nutritious foods are always good for the body—the more the better. If protein is good, they eat a lot of it. If beef is good, they eat plenty of that too. In this way of thinking, physical health is simply the result of consuming nutritious foods.

But traditional herbal medicine offers a different perspective. Certain foods—even nutritious ones—can harm the spleen–stomach system if consumed improperly.

Eating the wrong foods can:

• weaken the spleen–stomach system
• exhaust vital energy
• reduce the body’s defense system
• gradually weaken overall health
• and contribute to chronic disease over time

In this article, we explore how certain foods can quietly damage the spleen–stomach system—and how avoiding them helps preserve long-term vitality.

Most people worry about what foods lack nutrients. Few realize the real danger may come from foods that are too cold for the body to handle.

Have You Ever Seen This Happen?

One summer night in Hangzhou, a young man sat with his best friend at a busy roadside seafood stand.

Plates of bright red crayfish piled high on the table. Chili peppers filled the air with their spicy aroma. Ice-cold beer flowed freely.

His friend could only eat a little because of stomach problems.

So the young man did what many of us would do.

He finished the rest.

Nearly five pounds of crayfish.

A few hours later he was vomiting, sweating, and rushing to the hospital.

Everyone assumed the same thing:

Food poisoning.

But what if the real cause was something very different?

What If It’s Not Food Poisoning?

What if the real problem starts somewhere else?

What if it begins with something modern medicine rarely talks about:

Certain foods—especially cold foods—do not agree with the spleen–stomach system.

And when the spleen–stomach system is stressed, the body may rapidly lose vital energy—the very force that protects us and keeps the body balanced.

Many people assume that nutritious foods are always safe.

But traditional herbal medicine teaches something different:

When the spleen–stomach system receives the wrong foods—even nutritious ones—the consequences can be serious.

Symptoms like vomiting or diarrhea may actually be the body’s emergency response to protect itself.

But Why Would the Body Reject Nutritious Food?

This raises an important question.

If these symptoms are not simply food poisoning, what causes the spleen–stomach system to suddenly revolt?

To answer that, we need to explore a concept modern medicine rarely discusses:

The energetic nature of foods—and how they interact with the digestive system.

01 What Counts as “Nutritious” Food?

Traditional Chinese thinking has long ranked foods according to their perceived nutritional strength.

There is an old Chinese saying:

“Four-legged animals are less nourishing than two-legged animals.
Two-legged animals are less nourishing than one-legged animals.
One-legged animals are less nourishing than many-legged animals.”

Following this logic, foods like crayfish, which have many legs, are considered highly nutritious.

But here’s the real question:

Does “nutritious” automatically mean we should eat more of it?

Not necessarily.

Let’s look at a real story.

02 When Too Much of a Good Thing Turns Bad

This story took place in Hangzhou, Zhejiang Province.

Crayfish season had arrived, and prices were low. Restaurants and night markets were full of people enjoying this popular food.

One young man—let’s call him Wang—joined a friend for dinner.

Wang was about thirty years old and in excellent health.

His friend, however, had stomach problems and could not eat much.

So Wang did what many of us might do.

He ate all five pounds of crayfish himself.

When he returned home, he suddenly began experiencing vomiting and diarrhea.

Thinking it was a minor issue, he took some stomach medicine.

But as the night went on, the symptoms worsened.

He developed severe stomach pain, fever, and extreme fatigue.

Eventually, he had no choice but to go to the hospital for emergency treatment.

This raises a natural question:

What could possibly be wrong with eating crayfish—such a nutritious food?

03 Cold Foods and the Problem of Dampness

To understand this, we need to look at what typically happens during crayfish season.

From May to September, crayfish consumption peaks across China.

Interestingly, this is also the peak season for gastrointestinal illnesses—including acute gastritis, enteritis, and even bacterial dysentery.

Most of those affected are young people who consume crayfish together with:

• ice-cold beer
• iced drinks
• frozen foods

From the perspective of traditional herbal medicine, the explanation is straightforward.

Crayfish are considered a cold-nature food.

Now consider the typical eating environment.

Young people sit outdoors at night markets.
Crayfish are cooked with hot chili peppers and Sichuan peppercorns.
Then they wash it all down with ice-cold beer or cold drinks.

So the body receives a combination like this:

• Cold-nature seafood
• Ice-cold drinks
• Late-night eating

The result?

Several problems may occur.

01 Dampness Accumulation

Too many cold foods weaken digestion and allow internal dampness to accumulate.

This dampness creates an environment where harmful bacteria can grow and where digestion becomes sluggish.

02 Vital Energy Depletion

The spleen–stomach system must work overtime to transform and digest these foods.

This process consumes large amounts of vital energy, leaving less energy available for the body’s defensive system.

03 Loss of Vital Energy Through Sweating

Spicy food increases sweating.

Sweating further drains vital energy, weakening the body’s protective capacity.

Meanwhile, the external environment makes things worse.

From May to September, summer heat and humidity are at their peak.

Nighttime is when yang-energy declines and yin-energy rises, making it easier for cold and dampness to invade the body.

Under these combined pressures, vital energy circulation slows.

04 The result?

Symptoms like:

• vomiting
• diarrhea
• fever
• fatigue

Many people notice something similar even with simple cold foods.

Eat too much ice cream or drink ice-cold beverages quickly—and suddenly the body feels chilled, sometimes even producing goose bumps.

04 How Modern Health Science Explains the Same Problem

Interestingly, modern health science describes a similar process—just using different terminology.

During hot summer months:

• temperatures rise
• rainfall increases
• humidity becomes high

These conditions allow intestinal pathogens to multiply rapidly.

Food sold at outdoor night markets can therefore contain more bacteria.

At the same time:

Spicy foods cause heavy sweating, increasing thirst.
People drink more cold beverages.

Cold drinks dilute stomach acid and reduce its bacteria-killing power.

Cold exposure can also cause the digestive tract to contract, reducing blood flow and weakening its resistance to bacteria.

This combination allows harmful microbes to invade the digestive system, leading to acute gastroenteritis.

In other words:

Both traditional herbal medicine and modern health science recognize the same warning.

Diet matters enormously for digestive health.

05 Other Cold Foods That Can Cause Trouble

This does not mean we must avoid all cold foods.

The real principle is this:

Do not consume cold foods beyond what your vital energy can handle.

Here are some examples.

01 Oranges

A friend visiting from Hong Kong once discovered California oranges.

They were sweet, juicy, and refreshing.

Out of politeness, we encouraged him to eat more.

Unfortunately, he took that advice quite literally.

He ate an entire carton of oranges in one sitting.

You can probably guess what happened next.

02 Milk

Milk is also considered cold in nature.

For older individuals or those with weaker digestion, daily consumption may be difficult for the spleen–stomach system to handle.

Moderation is key.

03 Certain Medicines

Some medications also have cold properties that affect digestion.

When possible:

• consult your doctor
• read the side-effect information carefully
• take medicine with food if it irritates the stomach

Traditional herbal medicine often advises taking certain medicines after meals to protect the spleen–stomach system.

06 Practical Strategies to Protect the Spleen–Stomach System

A young person might say:

“I’m young and healthy. A little dampness won’t stop me from enjoying crayfish.”

Perhaps that is true.

But most of us would still prefer not to suffer afterward.

So what can we do?

Strategy 1: Strengthen the Spleen–Stomach System

After consuming too many cold foods, some people experience:

• loss of appetite
• fatigue
• poor sleep

These symptoms often signal excess dampness affecting digestion.

To restore balance, traditional practice focuses on strengthening the spleen–stomach system.

One classic approach is Five-Treasure Porridge, an ancient dietary formula used for centuries to nourish digestive energy.

You can find detailed explanations of this approach in the Resources section of this website.

Strategy 2: Use a Tapping Stick to Stimulate yuanqi Flow

Another traditional technique involves using a tapping stick to gently stimulate the body.

The tapping stick activates meridians and acupoints across the body.

Because meridians are densely distributed, broad tapping across the body can stimulate many energy points at once.

This practice can be done:

• anytime
• anywhere
• even while resting in bed

Focus on the Fenglong Acupoint

For spleen–stomach protection, one acupoint is especially useful.

Fenglong Acupoint (丰隆穴).

This point helps remove what traditional herbal medicine calls phlegm-dampness—internal damp accumulation that harms digestion.

Stimulating Fenglong can:

• improve vital energy circulation
• reduce dampness
• strengthen digestive function

How to Find Fenglong Acupoint

Finding Fenglong is surprisingly simple.

Draw an imaginary line between:

• the knee
• the outer ankle

The midpoint of that line is Fenglong.

In acupuncture, precise location matters.

But with tapping, simply tapping across the area will naturally stimulate the point.

Practice tapping for about five minutes daily.

Over time, this may help:

• circulate vital energy
• strengthen the spleen–stomach system
• reduce dampness accumulation

07 Looking Ahead

Today’s world offers endless food choices. But the real question is not what tastes good—or what is expensive.

The real question is: 

Does the food we eat truly nourish the body?

Does it support the spleen–stomach system so the body can generate abundant vital energy?

In this article, we explored what not to eat.

In the next article, we will explore the other half of the equation:

What should we eat—and how should we eat—to truly nourish yuanqi?
