Does Chinese Food Make You Sleepy?

Do you notice a pattern of sleepiness after eating Chinese food several times in a row? Many people who enjoy eating Chines food but feel sleepy after desperately desire what to do to remain active after consuming their favorite Chinese delicacies. Fortunately, you can understand why you really feel sleepy and what you can do about it.

So, does Chinese food make you sleepy? The answer to this is no. Chinese food in general does not make you sleepy. Just as some people claim to feel sleepy after eating Chinese foods, there are those who complain of sleeplessness or grogginess.

Some people report feeling sleepy or sleepless after eating Chinese food that a term was coined for the feeling; Chinese Restaurant Syndrome.

With these diverse reactions, it is obvious there may be another factor at play that makes it hasty to categorize Chinese food in general as sleep-inducing.

However, what is common to all these complaints is that the people involved either ate too much of the foods or the food has a high Monosodium Glutamate (MSG) content.


What Is Chinese Restaurant Syndrome?

Chinese restaurant syndrome, now outdated, was coined in the 1960s to define a group of symptoms that people observed after eating food from a Chinese restaurant. It is currently called the MSG symptom complex. The symptoms often include sleepiness, sleeplessness, headache, skin flushing, and sweating.

Monosodium glutamate (MSG), a food additive, is generally blamed for these symptoms. However, there’s minimal scientific evidence that depicts any link between MSG and these symptoms in humans.

The U.S. Food and Drug Administration (FDA) has declared MSG safe. Moreover, most people who eat foods containing MSG do not experience any problems. However, a few people have short-lived, adverse reactions to the MSG food additive.

Is the Chinese Restaurant Syndrome Real?

Most of the people who feel sleepy after eating Chines food overindulge at Chinese buffets, usually mixing foods that are cheap, difficult-to-digest, and fried in heavy oil. It, therefore, stands that the so-called Chinese Restaurant Syndrome is likely to be a reaction to the consumption of excessive salt while overeating heavy, but inexpensive Chinese food.

The same people that complain they’re sleepy after eating cheap Chinese food rarely ever claim the same feeling after eating lunch meats or popular-brand soups which often also contain MSG. they also rarely claim the same sensitivity to MSG when eating other glutamates. Glutamate occurs naturally in living cells and helps to provide a unique taste to tomatoes, eggs, and even sharp cheese. In fact, most American food companies low-key added MSG to their menu offerings, from soups to salad dressings.

In an Australian study where 71 volunteers who were sure of their sensitivity to MSG were given a mix of actual MSG tablets and placebos, those who got the real MSG didn’t report any ill effects. But those who received the placebo tablets reported the same symptoms that they felt after eating Chinese food.

MSG actually helps to increase appetite since it enhances the taste of foods and influences the body’s natural appetite-suppression system. Studies tend to favor the theory that feeling sleepy because of Chinese food is more likely due to overeating heavy foods than for any other reason.


Is MSG Safe?

The discussion over MSG’s safety has been ongoing for decades, which makes it one of the most researched food additives in history. For some reason, although over 60% of the Asian population purposefully consume MSG daily, its use in the West is strongly disapproved. Westerners would readily pay more to avoid MSG, even for their pets.

There have been extensive studies on the effects of MSG since 1959 which culminated in the FDA, United Nations, World Health Organization, and European Union, all listing MSG as a safe food ingredient. Another study by the European Union stated that MSG was also safe for both pregnant women and infants.

A collaborative of Chinese and American researchers in 2008 linked MSG with obesity. However, another Chinese study in 2010 debunked the find. The study later suggested that the enhanced flavors MSG gives foods tempt them to overeat (again), and the thirst that MSG causes is usually quenched with beer or sugary drinks which leads to weight gain. After all, Japan, which is the leading per-capita consumer of MSG, boasts of the world’s longest life expectancy AND the world’s lowest obesity rates!

  • Swelling in the throat
