1. Fried or greasy foods
When your stomach is upset, you should avoid fried and greasy foods. These foods are hard on the stomach and can make nausea worse.
According to a 2019 study published in the journal Ultrasound International Open, fatty fried foods tend to stay in your stomach for a long time, putting extra pressure on the stomach.
Therefore, it is best to avoid fried and greasy foods when you feel nauseous.
2. Milk
Although milk may seem harmless in your daily diet, it can make nausea worse.
Milk, cheese, yogurt, and other dairy products can irritate the stomach lining, especially if you're nauseous and about to vomit.
Dairy products can also affect your health if you are lactose intolerant and can cause digestive problems.
3. Spicy foods
Spicy foods are a no-no when you have nausea. Your stomach lining is already inflamed and the heat from spicy foods can further irritate it. This can lead to vomiting and make nausea worse.
4. Caffeine
Caffeinated drinks like soda, tea, and coffee can dehydrate your body, leading to nausea or even worse.
According to a review published in the journal Nutrients, coffee's reaction to stomach acid secretion can cause a number of digestive problems, including nausea.
5. Acidic foods
Foods high in acid, such as citrus fruits, tomatoes, or vinegar-based condiments, can irritate the stomach lining and make your nausea worse.
These foods can cause the stomach to produce more acid, causing discomfort and a high risk of vomiting.
