A diver’s performance and safety are significantly influenced by what they eat before and after a dive. Just like an athlete prepares for a big game, divers need to fuel their bodies with the right nutrients to ensure they have the energy and stamina required for their underwater adventures.

This guide explores the best foods to consume before and after a dive, helping divers maintain peak performance and quick recovery. Whether you’re planning a deep-sea exploration or a casual dive, the right scuba diver’s diet can make all the difference.

General Rules for a Scuba Diver’s Diet

When it comes to general guidelines, a scuba diver’s diet should:

• Limit fat intake to avoid diseases linked to obesity, such as diabetes, high cholesterol, and cardiovascular issues, which could hinder your diving activities.
• Ensure the diver stays hydrated.
• Supply energy: While diving isn’t extremely physically demanding, it burns a significant number of calories. Keeping warm underwater and carrying heavy equipment requires maintaining good physical condition, supported by other forms of exercise.

Breakfast and Scuba Diving

Despite common beliefs, it’s essential to have a proper breakfast before a standard morning 2-tank dive. Your body burns calories to stay warm underwater, and swimming and diving demand significant energy. A good breakfast supplies the necessary fuel, helping you avoid constant shivering during your dive.

What kind of breakfast is best for scuba diving days?

Choose a breakfast that provides sustained energy. A light meal without heavy fats, sugars, or oils is ideal. Options like cereal, fruit, yogurt, toast, muffins, bagels, and eggs offer slow-burning energy to keep you warm during your dive. Stick to bland, non-greasy, and non-acidic foods to avoid heartburn underwater, and don’t overeat—just enough to last until lunch.

A crucial tip for divers is to stay well-hydrated in the morning.

• Drinking tea, juices, and water can help prevent dehydration on the boat or while diving.
• Limit your intake of orange juice, as its acidity might cause seasickness.
• Avoid excessive coffee consumption since caffeine acts as a diuretic, leading to dehydration.
• Since dehydration can significantly impact DCS, ensure you drink plenty of water before diving or opt for decaf or tea instead.

The myth that eating before swimming causes cramps is debunked. However, it’s advisable not to eat anything within 45 minutes to 2 hours before diving to allow for digestion and avoid feeling queasy or seasick on a rocking boat.

If you’re prone to seasickness, opt for a light breakfast with foods like ginger snaps, dry toast, cheese, and crackers to help absorb stomach acids and improve your comfort.

Are Surface Interval Snacks Ok?

During surface intervals, it’s recommended to snack on high-carbohydrate foods like bananas, fruit, granola bars, energy bars, cereal bars, yogurt, cookies, and biscuits to provide instant energy for your next dive.

Rehydrate by drinking a lot of water in addition to sports drinks. Bananas are a popular choice, although some boat captains avoid them due to an old superstition that they bring bad luck to sailors.

Avoid heavy starchy foods during your surface interval; the goal is to replenish energy and fluids for your next underwater trip. After that, eat what you want.

Foods to Avoid Before Scuba Diving

Avoid alcohol before scuba diving, as it can lead to serious risks such as DCI, nitrogen narcosis, dehydration, hypothermia, and impaired judgment.

Avoid fatty, spicy foods, industrial pastries, and those high in refined sugar. These can hinder digestion, make you feel heavy, and cause gastric problems, ruining your dive..

When in an exotic country, wait to enjoy the local cuisine until after your dives. Stick to familiar foods in your scuba diver’s diet to prevent gastritis.

Skip soft drinks and carbonated beverages; the only bubbles you should worry about are the ones you make underwater.

A Scuba Diver’s diet after diving

As mentioned earlier, rehydrate by drinking water. Focus your diet on carbohydrates (at least 60%) to regain energy, incorporating foods like pasta, rice, and vegetables. Include proteins (such as bluefish) and vitamins from fruits and vegetables.
