What Food Should I Take Mountaineering?

Dried cranberries, walnuts, chocolate covered espresso beans, dates, Cheetos and dried mango offer a smorgasbord to the high altitude athlete.

 

 

What’s the best food to eat on high altitude treks, climbs or expeditions? The quick answer is: whatever tastes the best and will be something you will want to eat regularly. Climbing high can sometimes cause a lack of appetite.

During your training the food you eat in your meals and training sessions should be nutritious and antioxidant rich to promote recovery and performance. I recommend real foods. But for just a two day climbing trip you don’t have to worry as much about the food you eat being ultra-nutritious. On a short climb at altitude the focus is on consuming enough calories, carbohydrates and fluids.

Climbing a mountain burns calories. Lots of them! Rising stress hormone levels place a higher demand for fuel on your body. As calorie needs increase, athletes need to add to their caloric intake.

Moderately increasing carbohydrate intake is key in replacing glycogen stores in your body when climbing and compensating for the increased caloric demand at altitude.

Altitude makes water loss worse because at altitude you will breathe faster and more deeply. This is because the higher the altitude the lower the air pressure, so you take more breaths for the same amount of oxygen. This extra breathing leads to fluid losses. If you aren’t staying on top of your intake, dehydration may sneak up, and leave you feeling light-headed and nauseated.

When you are over 10,000 feet elevation drink 1 to 1.5 liters of water daily 3 to 5 liters of water plus 200-300 grams of carbohydrate. Monitor your urine color. It should be a light yellow. Sports beverage powder packs easily in a small ziplock bag to add to a water bottle.

Recommended sports beverages:

Gatorade Endurance, carbs

Fluid Performance Natural, carbs

Gatorade Thirst Quencher, carbs

GU Hydration Drink, carbs

Hammer HEED, carbs

Accelerade, carbs and whey protein

Powerbar Recovery, carbs and whey protein

When packing food for your upcoming climb it’s important to consider a few variables: calorie density, weight, durability, and enjoyment.

Food is important. Plan out your meals and snacks, pack them as well as you can in a way that will make them easy to eat on the upper mountain when you are cold and tired. Some foods come in a convenient packaging and others will need to be repacked in a Ziploc.

For day one, you can bring some fresh foods: meat sandwich, pita and cheese, string cheese, hardboiled eggs, fruit, carrot sticks, broccoli, for instance. For perishable food, it is advisable not to keep them above 41F for longer than 2 hours. Food-borne bacteria can multiply rapidly especially so in over 70F. It is better to be safe than sorry. Having the runs in the mountains would be a nightmare.

Below are a few tips to consider:

  • Bring a variety of foods that you like.
  • Bring a mix of sweet, salty and savory.
  • Things get beat up in a backpack so consider durability (think bagels vs. bread and thick pretzels vs. thin ones).
  • Bring food you know and like and have experimented with on your training hikes.
  • Remember extra food is far better than not enough, but not too much. Food is heavy. That’s why it takes some careful planning.
  • Think about bringing no more than a pound per day.
  • You can and should eat every time you stop for a break. On a typical 3 day climb of Mt. Rainier, I recommend bringing about sixteen 200-400 calorie snacks (that gives you a little extra).
  • Keep some small snacks like cut up mangos, nuts, protein bars cut into bite-size in your pockets so they are easily accessible when you take a break. Keep bars that freeze in your inner coat pockets to keep them warm.
  • Test the food you are taking when it’s frozen to see if it’s still edible.
