5 Foods and Drinks to Skip When You’re Sick, According to Health Experts

When you’re sick, your body has exactly two main jobs: fight the illness and keep you functioning like a reasonably civilized human. That means your usual “treat yourself” menu may need a temporary timeout. A triple-shot latte, greasy takeout, spicy wings, or a giant soda might sound comforting in the moment, but when your stomach is queasy, your throat is scratchy, or you’re losing fluids, those choices can make recovery feel like a very rude sequel.

The good news is that you do not need a perfect “sick-day diet.” You just need smart, simple choices that support hydration, digestion, and comfort. Health experts generally agree that certain foods and drinks tend to backfire when you have symptoms like nausea, vomiting, diarrhea, congestion, reflux, or dehydration. In other words, this is not about food morality. It is about giving your body less drama while it is already busy.

Below are five foods and drinks to skip when you’re sick, plus what to reach for instead.

Why What You Eat Matters When You’re Sick

Illness changes the way your body handles food and fluids. Fever can increase fluid loss. Vomiting and diarrhea can dehydrate you fast. Congestion may dull your appetite. A sore throat can make swallowing feel like a bad idea. And stomach irritation can turn rich or spicy foods into instant regrets.

That is why health experts often recommend easy-to-digest meals, smaller portions, and plenty of fluids. The goal is not to eat like a sad piece of toast forever. The goal is to avoid making symptoms worse while staying nourished enough to recover.

1. Alcohol

Why it is a bad idea when you’re sick

If there were a “least helpful guest” award for sick days, alcohol would be a serious contender. It can contribute to dehydration, which is the opposite of what you want if you have a fever, vomiting, diarrhea, or even a bad cold. When you are already losing fluids, alcohol can make you feel weaker, dizzier, and more wiped out.

It can also irritate the stomach and worsen nausea. If you are dealing with a stomach virus or food poisoning, alcohol may turn mild misery into a full-body protest. On top of that, alcohol may not play nicely with common over-the-counter and prescription medicines, including some cold, flu, pain, and nausea treatments.

And no, a “hot toddy” is not magical medicine. It may feel cozy, but cozy is not the same thing as clinically helpful.

What to choose instead

Water is the obvious winner, but it is not the only one. Broth, ice chips, oral rehydration solutions, diluted juice, or caffeine-free tea may be easier to tolerate depending on your symptoms. If your stomach is touchy, slow sips usually work better than chugging like you are trying to win a contest no one asked for.

2. Coffee, Energy Drinks, and Other Caffeine-Heavy Beverages

Why they can make you feel worse

When you feel exhausted, coffee can seem like a survival tool. But if you are sick, especially with stomach issues, caffeine may not be doing you any favors. It can irritate the stomach, increase jitteriness, and make it harder to rest. It may also contribute to fluid loss or make you feel less hydrated when you already need more fluids.

This matters even more if you have diarrhea, vomiting, or poor appetite. A giant coffee, caffeinated soda, or energy drink may sound like it will “perk you up,” but it can leave you feeling shakier, more nauseated, or more uncomfortable. Energy drinks are especially unhelpful because they often combine caffeine with lots of sugar, creating a one-two punch your recovering body did not request.

What to choose instead

Try warm water with honey if you have a cough, caffeine-free herbal tea, broth, or plain water with a squeeze of lemon if citrus does not irritate your throat or stomach. If you cannot stand plain water, a low-sugar electrolyte drink or oral rehydration solution may be easier to manage.

3. Fried, Greasy, and High-Fat Foods

Why your stomach may reject them

Fried chicken, fries, burgers, pizza, and rich creamy dishes are often harder to digest than bland, lower-fat foods. When you are nauseated or dealing with diarrhea, high-fat foods can sit in the stomach longer and increase discomfort. Translation: your body is already trying to keep things under control, and a basket of fries may show up like a tiny edible villain.

Greasy foods can also be rough if illness has triggered reflux, bloating, or general stomach upset. Even when you are hungry, going straight for heavy comfort food may leave you feeling fuller in the worst possible way.

What to choose instead

Think simple and soft: toast, rice, oatmeal, bananas, applesauce, crackers, noodles, broth-based soup, plain potatoes, or baked chicken if you are ready for protein. You do not need to eat a “perfect sick menu,” but lower-fat foods are usually easier on the stomach until symptoms calm down.

4. Spicy Foods

Why they are risky on sick days

Spicy foods are glorious when you are healthy and feeling bold. When you are sick, they can be a gamble. If you have nausea, vomiting, diarrhea, reflux, or a sore throat, spicy dishes may increase irritation and make symptoms feel more intense.

For people with stomach bugs, spicy foods can push a sensitive digestive system in the wrong direction. For people with heartburn or reflux symptoms, spicy foods may trigger more burning and discomfort. And for a painfully sore throat, hot sauce can feel less like seasoning and more like a personal attack.

Some people swear spicy soup helps “clear everything out.” Maybe. But if it leaves you coughing, sweating, and regretting your life choices, it is not helping much.

What to choose instead

Go for mild flavors and softer textures. Chicken soup, plain noodles, mashed potatoes, rice porridge, oatmeal, scrambled eggs, or toast are usually safer bets. If you want flavor, try a little ginger, parsley, or a small amount of cinnamon rather than a full spice explosion.

5. Super-Sugary Foods and Drinks

Why too much sugar can backfire

Sugary drinks and snacks often sound appealing when you have no appetite. They are easy, familiar, and sometimes the only thing that does not seem totally unappetizing. But lots of added sugar can be rough on a sensitive stomach, especially if you have diarrhea or nausea. Highly sweet drinks may also be less effective for hydration than balanced fluids made for rehydration.

Regular soda, oversized fruit juice, slushies, energy drinks, frosted pastries, and giant candy hauls are not exactly a dream team when you feel awful. In some people, sugary foods and drinks can worsen stomach discomfort or contribute to loose stools. This is especially true when you are already dealing with gastroenteritis or food poisoning.

That does not mean you need to fear every gram of sugar. It means a sick day is probably not the best time to turn your kitchen into a candy convention.

What to choose instead

Choose water, broth, diluted juice, unsweetened applesauce, plain crackers, bananas, rice, or electrolyte solutions if dehydration is a concern. If you want something sweet, keep it gentle and simple rather than ultra-processed and super sugary.

What About Dairy?

Dairy deserves a quick reality check because it is one of the most misunderstood sick-day topics on the internet. For most people, dairy does not create extra mucus during a cold. So if you are sipping a little milk or eating yogurt and it sits fine, that is not automatically a problem.

But dairy can be trickier when you have vomiting, diarrhea, bloating, or a stomach virus. In those cases, some people temporarily tolerate milk, ice cream, and creamy foods poorly. If dairy seems to worsen gas, diarrhea, or stomach discomfort, it may be smart to pause it for a bit and reintroduce it slowly once you feel better.

So the answer is not “dairy is always bad.” The answer is “it depends on your symptoms.” Your stomach gets a vote here.

What to Eat and Drink Instead When You’re Sick

If you are wondering what actually helps, the best choices are usually boring in the most beautiful way. Try these:

• Water, ice chips, or oral rehydration solutions
• Broth or clear soups
• Toast, crackers, rice, oatmeal, or noodles
• Bananas and applesauce
• Plain potatoes or simple cooked cereals
• Small amounts of lean protein, such as chicken, turkey, or eggs, when tolerated
• Caffeine-free tea or warm water with honey for coughs, if appropriate

Small meals are often easier than large ones. Slow sips are often better than big gulps. And if you are not very hungry, prioritize fluids first. Hydration is often the main event.

When to Call a Doctor

Food choices can help with comfort, but they are not a substitute for medical care when symptoms are serious. Contact a healthcare professional if you have trouble keeping liquids down, signs of dehydration, bloody diarrhea, black stools, severe pain, confusion, or a high fever. Ongoing vomiting or diarrhea also deserves attention, especially in children, older adults, and people with underlying medical conditions.

In plain English: if you are getting weaker instead of better, do not just keep nibbling crackers and hoping for a miracle.

Common Experiences People Have With These Foods When They’re Sick

One of the most common experiences people describe is drinking coffee because they are tired, only to realize the caffeine made everything worse. They were already shaky from not eating enough, already dehydrated from fever or loose stools, and already low on sleep. The coffee seemed like a rescue plan. Instead, it turned into a fast track to jitters, stomach irritation, and the kind of “Why did I do that?” regret usually reserved for bad haircuts and late-night online shopping.

Another very familiar experience happens with greasy comfort food. Someone finally feels hungry after a day of feeling awful, decides this is the perfect moment for fries, pizza, or a cheeseburger, and then spends the next hour wishing they had chosen toast and soup instead. Heavy foods can feel satisfying for about five minutes. After that, the stomach often files a formal complaint. People commonly describe bloating, nausea, reflux, or that heavy, sloshy feeling that makes lying down feel impossible.

Spicy food is another classic gamble. A lot of people convince themselves that a super-spicy bowl of noodles will “sweat the cold out” or blast through congestion. Sometimes it seems to open the nose briefly, which feels promising. But if the person also has a sore throat, heartburn, nausea, or diarrhea, the victory lap does not last long. What started as “I need flavor” can turn into coughing, stomach burning, and a deep emotional bond with a glass of water.

Sugary drinks create their own kind of confusion. When people feel weak, they often reach for soda, juice, or energy drinks because those seem easy to get down. Sometimes they do go down easily at first. The problem is that many people then feel more nauseated, more bloated, or still not truly hydrated. Parents often notice this with kids too: the child wants a sweet drink, takes a few big sips, then the stomach gets upset all over again. It is a very understandable move, just not always a helpful one.

And then there is alcohol, which tends to show up in stories that begin with, “I thought one drink would help me relax.” People often report that it made them feel drier, sleep worse, or wake up even more miserable. When you are already sick, the body is not looking for party tricks. It is looking for fluids, rest, and foods that do not create extra work. That is why so many people end up saying the same thing after the fact: simple food felt boring, but boring worked. And when you are sick, “worked” is a pretty beautiful word.

Conclusion

When you are sick, the smartest menu is usually the gentlest one. Alcohol, caffeine-heavy drinks, fried foods, spicy foods, and super-sugary treats may be fine on better days, but during an illness they can worsen dehydration, irritate the stomach, and drag out your discomfort. That does not mean you need to eat like a monk forever. It just means your body will probably do better with simpler choices until the storm passes.

Think hydration first, bland foods second, and culinary ambition later. Your future healthier self can go back to coffee, hot wings, and celebration snacks. Sick-day you needs water, rest, and a little less chaos on the plate.
