Part 3 of 3:
Diet is very important in diving health.

A balanced diet is necessary in preparing for a day strenuous diving. Rest and diet are very important in diving health recommendations.
Protein is needed to build or replace body tissue and is supplied by nut butter, milk, eggs, meat, fish and poultry.

Carbohydrates, also known as sugars and starches, are important for quick energy, and include vegetables, breads, and cereals.
Minerals such as calcium, magnesium and potassium are need by your muscle for proper function.

Calcium helps form and maintains healthy teeth and bones also can help prevent osteoporosis. It can be obtained from milk and dairy products such as yogurt, cheeses and buttermilk.

Magnesium is an essential mineral for bone health. It can be obtained from some types of nuts (such as almonds and cashews) and soy products (such as soy flour).

Potassium is an essential mineral required for proper nerve and muscle function. It can be obtained from fruits such as citrus fruits, bananas, kiwi, prunes and apricots. Low levels of potassium can cause cramps.

Dietary tips for divers

  • Avoid eating greasy foods such as pizza, bacon sausage before a dive because they are difficult to digest.
  • Eat a good breakfast the day of the dive. Eat easy to digest foods such as pancakes, toast, sweet rolls, waffles, cereals and boiled eggs.
  • Milk increases mucous production. If you must use milk, try non-fat milk and only use a small amount. Coffee and tea will contribute to dehydration and hypothermia from increased urination. Juice is a better substitute for a drink at breakfast.
  • Eat lightly if a meal is to be consumed immediately before a dive.
  • Between dives, eat foods which will supply nutrients and calories for quick energy. Dried fruits, nuts and a small amount of chocolate are suggested.
  • Stay hydrated by drinking lots of water (around 2 liters) during a day of diving.
  • Prevent cramps by staying well hydrated. Avoid drinking carbonated beverages as they may cause excessive gas problems.
  • Avoid alcohol before, or after diving because alcohol dilates blood vessels and contributes to decompression sickness.

A proper diet is part of the secret to feeling good and enjoying a dive.
