Foods Not To Eat Before Scuba Diving

There are a lot of things that you should avoid eating before diving. Here are some of the most common ones:

1- Heavy Meals

Food can significantly affect your performance underwater and can even lead to serious health issues if you don’t take the necessary precautions. 

When scuba diving, it’s essential to consider your food choices.

You don’t want to be carrying around extra weight during your dive, so here are a few things you should avoid eating before diving:

  • Coffee and Tea – These will give you the jitters when underwater and could cause you to panic. Plus, coffee is full of caffeine which can affect how your body reacts when oxygen levels get low.
  • Alcohol – Alcohol impairs judgment, leading people to make poor decisions that could be dangerous. If you’re going diving in cold water, then alcohol might not be such a good idea for your health after all.
  • Salads and Sandwiches can get soggy underwater, and salads can leave you with a nasty stomach ache when you come up for air. Instead of these foods, stick with something light like fruit or crackers on your dive.
  • Fatty Foods – Eating fatty foods before jumping into the water will make it harder for your body to regulate its temperature.
  • Light snacks such as fruits and vegetables are generally safe to eat before a dive as long as they are consumed at least three hours ahead. It is also important to remember that these snacks should be low in fat and sugar for optimal safety and performance underwater.

2- Raw Or Undercooked Meat

First and foremost, when you eat raw or uncooked meat, bacteria can grow on the surface of the meat. So if you’re going to be eating raw or uncooked meat while scuba diving, ensure that your hands are washed thoroughly before handling any food, even if you don’t plan on touching anything else with your hands.

This includes meat that has yet to be pre-cooked or partially cooked. It may look great, but it is not safe to eat this way. Raw meat contains bacteria that can result in food poisoning and other diseases. Plus, if your dive computer detects bacteria in your air tank, you will be denied entry into the water.

3- Shellfish

Shellfish can carry bacteria that cause serious illness, like clams or oysters, especially when raw or uncooked. If you have shellfish allergies, then no amount of cooking will make them safe for consumption.

 Shellfish can cause nitrogen narcosis, making it hard to stay focused and alert while underwater. This is dangerous because you could pass out or drown if something goes wrong.

4- Dairy Products

Dairy products are a great source of calcium, but they can be a wrong choice for scuba divers.


Dairy products can affect your body’s ability to absorb nitrogen. The nitrate content of dairy products is highest in aged cheese and yogurt, and it tends to increase with the amount of time spent in water.

Some people have allergies to dairy products, so they cannot safely use dairy foods for eat before scuba diving, even though they may seem harmless at first glance. 

5- Sugary Foods 

One of the most common dangers of scuba diving relates to what we eat and drink in preparation for our dive. Many food items should be avoided before diving because they can cause gastric upset or negatively affect your underwater experience.

The most important thing you need to know about food and drinks while scuba diving is that sugar-sweetened beverages (such as soda) should be avoided entirely because they can cause significant problems if ingested underwater.

This eating has no nutritional value and instead adds weight which could affect buoyancy control during dives when you need it most.

The main reason sugary foods aren’t good for you to consume before diving is that they can cause dehydration. 


Therefore, it is concluded that scuba diving is the best activity that keeps people active. However, it needs several precautions before going for it. The most important is to have food eat before scuba diving. 

Remember, it is always best to follow caution when it comes to food consumption before a dive so that you can enjoy your time in the water without any complications or risks!

We have provided several guidelines regarding it. By following these guidelines and understanding what not to eat before scuba diving, you can ensure that you stay safe and get the most out of your experience underwater. You should eat as little as possible before diving and drink only water.

The above-mentioned foods and drinks should not be consumed before scuba diving. The last thing you want to deal with is indigestion while plunging into the ocean’s depths, so it’s best to avoid these items altogether.

If you’re going to eat something before your dive, be sure to plan out exactly what it will be and how much you’ll be eating.


What foods should I avoid eat before scuba diving?

Prior to diving, it is preferable to refrain from eating anything with a lot of fat, sugar, or salt. This includes fried foods, sweets, and processed snacks like chips and crackers. 

Additionally, it is best to avoid alcoholic beverages and caffeine as these can cause dehydration and increase the risk of decompression sickness.

How long before a dive should I stop eating? 

It is advised to stop eating three hours or more before a dive. This allows your body time to digest the food and avoids gastrointestinal issues when diving. To stay hydrated, it’s also advisable to consume a lot of water. 

Exactly what foods can improve scuba diving performance?
