What Should You Not Eat if You Feel Nauseous?

5 min read

Nausea is a very common symptom with many possible causes, from viral infections to pregnancy. When you feel nauseous, your food choices can either help or hurt. It is critical to understand what you should not eat if you feel nauseous to avoid aggravating an already upset stomach and promote recovery.

Quick Summary

Trigger foods like greasy, spicy, and high-sugar options can aggravate an upset stomach. Limiting strong-odored foods, caffeine, and alcohol is key to finding relief and supporting digestion during illness.

Key Points

  • Avoid Fatty Foods: Steer clear of fried and greasy foods, as they are slow to digest and can make nausea worse.

  • Skip Spicy Meals: Spicy ingredients like capsaicin can irritate your digestive system, intensifying discomfort.

  • Limit Sugar: Overly sweet foods, including sugary drinks and desserts, can aggravate a sensitive stomach.

  • Be Cautious with Dairy: Many dairy products are high in fat and can be difficult to digest, especially during illness.

  • Cut Caffeine and Alcohol: These beverages are dehydrating and can irritate the stomach lining, hindering recovery.

  • Eat Smaller, Bland Meals: Instead of triggers, opt for small, frequent portions of bland foods like toast, crackers, and rice.

Feeling a queasy, churning sensation in your stomach can make the thought of food unappealing, but knowing what to avoid is as important as knowing what to consume. Certain foods, due to their composition, can worsen nausea and trigger further digestive distress. By eliminating these triggers, you can provide your digestive system with the best chance to settle down and recover smoothly.

The Worst Foods to Avoid When Nauseous

Fatty and Fried Foods

High-fat foods are notoriously difficult for the body to digest, a process that slows down gastric emptying. This causes food to sit in your stomach longer, increasing feelings of heaviness and discomfort that can intensify nausea. Fried foods, processed meats like sausage, fast-food burgers, and creamy pastas are common culprits. Opting for lean protein prepared simply, such as baked chicken or poached fish, is a much better choice.

Spicy Foods

Spicy foods, which often contain capsaicin, can irritate the delicate lining of your digestive tract. This irritation can lead to a burning sensation and increased discomfort, which is the last thing your stomach needs when already upset. Common examples to avoid include curries, chili, hot sauce, and certain Mexican dishes. It is best to stick to a bland diet until your symptoms subside.

High-Sugar Foods and Artificial Sweeteners

While a sweet craving might feel tempting, very sweet foods and beverages can cause problems. A sudden spike in blood sugar can exacerbate nausea for some people. Additionally, many processed sweet foods are also high in fat, creating a double whammy for your stomach. It's also worth noting that sugar substitutes and sugar alcohols can cause digestive distress, including gas, bloating, and diarrhea. This means sugary candies, pastries, and rich desserts are off the menu for now.

Dairy Products (For Some)

Many dairy products are high in fat, making them hard to digest when your stomach is sensitive. Furthermore, some people may experience temporary lactose intolerance when they are sick with a stomach bug, as the illness can cause a short-term deficiency of the lactase enzyme. For these reasons, milk, cheese, and creamy sauces can worsen nausea and lead to gas or diarrhea. Plain, non-fat yogurt may be better tolerated in small amounts, but it's often safer to avoid dairy entirely at first.

Caffeine and Alcohol

Caffeine and alcohol are both known to irritate the stomach lining and act as diuretics, which can lead to dehydration. This is especially dangerous if nausea is accompanied by vomiting. Alcohol can be particularly harsh on the digestive system and is best avoided completely. Instead, focus on clear, hydrating fluids.

Foods with Strong Odors

Sometimes, the smell of food alone is enough to trigger nausea. Warm or hot foods tend to have a stronger aroma than cold ones, which is why eating foods at room temperature or colder can be helpful. Avoiding strong-smelling items like some cheeses, fish, and certain spices can prevent the olfactory triggers that cause your stomach to turn. Consider asking someone else to cook for you if kitchen smells are an issue.

What to Eat Instead: Bland and Soothing Alternatives

When dealing with nausea, the focus should be on small, frequent, and bland meals to keep your stomach settled. Here are some options to consider:

  • The BRAT Diet: Bananas, white rice, applesauce, and toast are staples for a reason. They are low in fiber and easy to digest.
  • Clear Liquids: Staying hydrated is crucial. Water, clear broth, and weak herbal teas are good choices.
  • Ginger: Ginger has long been used as a natural anti-nausea remedy. Ginger tea, ginger ale (flat), or sucking on crystallized ginger can be effective.
  • Cold Foods: Popsicles, gelatin, or cold chicken broth can be easier to tolerate as they don't have strong smells.
  • Crackers and Pretzels: These dry, salty foods can help absorb stomach acids and are easy on the digestive system.

The Science Behind Your Food Choices

By understanding why certain foods exacerbate nausea, you can make more informed choices during recovery. Here’s a breakdown of the physiological reasons:

  1. Gastric Emptying: High-fat foods slow down the rate at which your stomach empties its contents. This prolonged digestion time can lead to feelings of fullness, bloating, and heightened nausea.
  2. Stomach Irritation: Spicy foods and alcohol irritate the mucous membranes lining the stomach. This direct irritation can trigger or worsen the sensation of nausea.
  3. Lactose Malabsorption: For many, the gut's ability to produce the lactase enzyme is temporarily reduced during illness. Consuming lactose-rich dairy products can then cause additional gastric distress.
  4. Electrolyte Imbalance: Vomiting can cause significant dehydration and loss of electrolytes. Drinks containing caffeine or alcohol, as well as those that are very high in sugar, can worsen this imbalance rather than help.
  5. Olfactory Triggers: The strong scent of hot food can be a powerful trigger for the nauseous sensation. By eating cooler, blander foods, you can minimize these sensory inputs.

Nausea-Triggering Foods vs. Stomach-Soothing Foods: A Comparison

Category Avoid When Nauseous Enjoy Instead Reason
Fats Fried chicken, creamy sauces, sausage, french fries Broiled chicken breast, plain boiled potatoes, toast Slows gastric emptying, heavy to digest
Spices Chili, curry, hot sauce, black pepper Bland boiled rice, plain pasta, crackers Irritates stomach lining
Sugars Doughnuts, cakes, soda, rich desserts, high-sugar juice Applesauce, plain gelatin, popsicles Can cause blood sugar spikes and add to heaviness
Dairy Whole milk, cheese, ice cream Plain, non-fat yogurt (small amounts), water, tea High in fat and potentially hard to digest lactose
Beverages Coffee, alcohol, full-sugar carbonated soda Flat ginger ale, water, herbal tea Dehydrating, irritating to stomach lining
Odors Hot, strong-smelling foods like fish, strong cheeses Room-temperature or cold foods Strong scents can trigger or worsen nausea

Conclusion: Listen to Your Body

When you feel nauseous, the key to relief lies in avoiding foods that are difficult to digest, irritating, or overly sweet. By sticking to a bland diet of easily tolerated foods like the BRAT diet staples, clear liquids, and ginger, you can help calm your stomach. Remember to eat small, frequent meals and avoid strong odors. If nausea persists, always consult a healthcare professional.
