Trekking in the Himalayas can be fun and exciting but also is a strenuous job. Depending on the length, maximum altitude and terrain of a trek, it is usually advised for travelers to be in good physical shape. As you go higher up the Himalayas, risks of injuries are higher and problems such as altitude sickness and Acute Mountain Sickness are a common occurrence. Trekking is a surreal experience but requires adequate preparation and precautions to make it an enjoyable one. It is always good to know what you are getting into and how your body reacts during a trekking adventure. Travelers usually make sure that they have the proper equipment, guides, maps, layers and first aid kits on treks but one common thing that trekkers usually either overlook or are misinformed about the optimal diet required on a trek. Especially when it comes to the consumption of non-veg food
It is a very common practice for trekkers all over the world to focus on consumption of meat while on treks. This is usually out of the necessity of the situation/location or to compensate for the extra protein that the body requires during the journey. But as one goes higher up the mountains, the difference in altitude causes the body to react differently to the food that is consumed. The high altitude causes the atmospheric pressure to drop, which causes the carbon dioxide dissolved in our bloodstream to be diffused outwards. This is due to the basic fact that molecules tend to flow from an area of higher pressure to an area of lower pressure. This diffusion of carbon dioxide leads to a person feeling bloated which is commonly known as flatulence. In mountaineering science, the term for this phenomenon is HAFE (High Altitude Flatulence Expulsion). Our digestive system is not used to the high altitudes and naturally undergoes a level of high stress during this time.
Meat is a great source of protein and sounds very tempting while on treks because the body is exhausted as it burns an average of 7 calories per kg per hour during medium level trekking. So, if you weigh 70 kgs, you burn a whole 490 calories per hour. But, meat, which is already harder for our digestive system to dissolve and break down in normal conditions, becomes a nightmare for the body to process at higher altitudes.
Just think of the times when you had the excess amount of meat and were just not able to move afterward due to flatulence and gas issues, the body is more susceptible to similar situations at higher altitudes. Furthermore, rapid and excess consumption of meat at higher altitudes can also cause severe loose motion. The mountains are not equipped with luxury bathrooms and you do not want to be in such a situation!
After all, it is suggested that a person carrying out medium intensity exercise such as trekking should have the following nutrient profile:
Trekkers should try to consume fresh food as much as possible. Canned and stored items should be avoided if possible. The rule of thumb for meals on treks is to make sure that your body gets an adequate amount of carbohydrates as it is easily converted to energy, which is a constant requirement throughout. Mornings especially should be heavy on carbohydrates. Cornflakes is a good option for breakfast. During treks, you should avoid meat but should not totally disregard protein consumption. Soybeans and Oats are considered as the best sources of protein on treks. Their amounts need to be low as it takes quite a while for them to break down.
An ideal ratio of carbohydrate to protein during lunch and dinner is 3:1. Eggs are another great option during treks if consumed moderately. They help to prevent sore muscles and replace muscle protein during treks. Travelers should always ensure that they are properly hydrated. It is recommended that trekkers drink at least 5 liters of water per day to keep up with the strain that comes with trekking. They should also carry highly nutritious food such as dry fruits, nuts, trail mix and fruits with them. Chocolate and other sweet items should strictly be avoided. It is strictly recommended that alcohol is avoided during extreme treks as it drains the body while causing dehydration.
So, make sure you regulate the amount of protein you consume before and during a trek. Doing so will ensure that you will be able to enjoy the splendid beauty of the mountains without having to run to the bathroom frequently. Once you get back down to normal altitudes, you are free to feast like a beast!!
