What to eat if I have nausea and vomiting


Chicken is an excellent protein that you can add to your diet if you have nausea and vomiting. Chicken, also turkey and soy meats, have a very mild flavor and tend to take on the taste of the ingredients with which they are seasoned. Therefore, you can prepare them on the grill without adding many spices to have a neutral and light flavor that does not wake up nausea. To make it easier to chew this type of meat, you can boil it and then shred it; in this way, it will be much easier to digest.

Dry food

Dry foods decrease saliva production in the mouth, which reduces nausea and vomiting; for this reason, we recommend eating them just when you feel that the discomfort may worsen. What are these foods to prevent nausea and vomiting? Crackers, popcorn, non-whole grains, peanuts, granola. Eat them on an empty stomach for best results throughout the day.

Fresh food

Foods that are fresh to the palate and pass quickly on the tongue without needing to be chewed several times to swallow are also ideal for eating if you have nausea and vomiting. Yogurts, ice cream, sorbets, and fruit juice are excellent.

Soft foods

When you wonder what to eat if you have nausea and vomiting, you must remember that soft foods are the best option to avoid gagging when chewing and swallowing. Mashed potatoes or sweet potatoes, omelets, gelatin, chicken not very well done, or vegetable creams are highly recommended options.

Soups and broths

Creams, consommés, soups, and broths are, without a doubt, the best option to feed yourself properly when the body asks you to reject any food, the appetite does not appear, and nausea and vomiting are extreme. The soup is prepared based on vegetables, proteins, and vegetables, which makes it rich in vitamins and minerals, ensuring that your body receives all the nutrients it needs in a single meal to avoid decompensation. As if that were not enough, the soup is liquid for the body, so it prevents dehydration, which can be very common when a person has vomited a lot.


Avoid citrus fruits, which can irritate the digestive tract and worsen discomfort. Instead, fruits like papaya boost digestive health and eliminate nausea, reflux, and heartburn.

Drink water

Fluid intake is essential to prevent the body from becoming dehydrated due to vomiting. If the water increases your nausea, try a popsicle or chew ice.

Includes bananas

When a person has vomited several times, their potassium level in the body decreases and makes them feel weak. Preventing low potassium is possible if we add bananas to our meals; since this fruit, in addition to being a band, has high contents of this substance, it can also be crushed as a porridge.
