When All Hell Breaks Loose (43 page)
Harvest rain whenever possible using a variety of nontoxic, nonpermeable materials such as the roof of your home, or suspended tarps or plastic sheeting. Disinfect rainwater before drinking using the described disinfection methods.
"Thou shouldst eat to live, not live to eat."
—Socrates
W
hile food is not a priority in a short-term survival scenario, which lasts on average seventy-two hours or less before you are rescued, for an extended emergency it's a must-have commodity. Food is a hotly debated item in survival and everyone has their opinion about what you should have on hand and how much. As psychological stress is such a huge part of every survival scenario, knowing where your food is coming from and having enough for your family will do wonders for everyone's peace of mind. Consider storing a few snacks in your car and office as well.
In a nasty, long-term crisis in which you are unable to resupply your cupboard, you will be forced to ration your family's food. Take the mind-set
now
that your survival rations, in their truest sense, are just that, THEY ARE RATIONS; and rations are to be rationed. Beware, as the Earth's history is full of fools who willfully chewed through their survival supplies in short order, their deaths being the only proof of their bad planning. If you want to live high on the hog for a few days, purposefully storing and eating gourmet supplies at the beginning of your ordeal, that's your choice, but be able to get down and dirty with a food supply that is supernutritious and easily stored and rationed, at the expense of taste if need be. Much about your food storage strategy, of course, revolves around the wants and needs of your family.
The Big Three: Macronutrients in Food
Foods contain three macronutrients: carbohydrates, fats, and proteins, along with trace amounts of micronutrients such as minerals and vitamins. Each type contains a certain amount of kilocalories (kcal) or units of food energy and metabolizes or "burns" differently within the body. Fats contain the greatest amount of kilocalories at a whopping 9.3 kilocalories per gram. Carbohydrates come in second with 3.79 kilocalories per gram, and then proteins with 3.12 kilocalories per gram. Each kilocalorie is equivalent to 1,000 calories and is the quantity of heat required to raise the temperature of 1 kilogram of pure water 1 degree C. One pound of body weight equals around 3,500 kilocalories. At 280 kilocalories a pop, that's nearly thirteen Snickers candy bars!
The largest energy reserves are found in the largest parts of the body, principally muscle (around 28 kilograms) and fat (15 kilograms). On average, a healthy body contains a storehouse of energy: around 1,200 kilocalories of carbohydrates, 24,000 kilocalories of protein, and 135,000 kilocalories of fat. As stated earlier, the burn rates of macronutrients, how their kilocalories are metabolized by the body, vary. Just as adding various types and sizes of firewood to a fire influences the burn size and time duration of the flame, so the three macronutrients influence the body in much the same way. Fats, as an example, like larger fuelwood, contain the most calories per gram, but also require more oxygen to oxidize their components down for metabolism by the body. Simple sugars (carbohydrates), like hard candies, act the same as smaller kindling wood and don't contain many kilocalories, but they break down very quickly and thus are metabolized by the body very fast. Putting kindling-size wood on a fire will produce a huge flame in a heartbeat but it's short-lived.
Almost everyone at some point has "hit the wall," as an athlete would say, having burned up their available carbohydrate supply. Eating a few simple sugars and carbohydrates might be all that's necessary to jump-start your body's system. If your survival tasks become extremely physical, working at less than 60 percent of your maximum exertion level uses more fats than carbohydrates, thus helping to prevent blood glucose depletion. This physiological rule is one that aerobics instructors use to their advantage in helping clients lose fat while they maintain the energy needed to keep exercising during their class. If the weather is cold and available body carbohydrates are drained, heat production starts to fail and you become hypothermic much easier. In this situation, you
must
eat simple carbohydrates to tap into your body's remaining fat reserves.
Subjecting your body to cold weather without the protection of adequate clothing or shelter will cause your body to burn more calories. In other words, having adequate clothing or shelter for the climate and season will make your emergency food supplies last longer. Not only what you eat, but also
how
you eat can affect your body's thermoregulation in cold weather. Eating smaller, more frequent meals increases the body's metabolism, thereby burning more calories for digestion, a process referred to as
diet-induced thermogenesis
. This thermal effect of food, or "TEF" principle, increases your metabolism, which in turn increases the amount of calories burned. These increased calories produce more internal heat for the survivor when needed.
POTENTIALLY PROBLEMATIC PROTEINS
Proteins are not ideal survival foods in hot environments for several reasons. If water is scarce, proteins should be avoided, as the metabolism of protein depletes body water stores. Protein metabolism produces urea, a toxic compound excreted by the kidneys. The more protein you eat, the more water the body devotes to the production of urine in order to rid the body of urea. Eating quantities of protein in a limited-water situation hastens death through dehydration long before starvation. However, in long-term survival scenarios where starvation is a possibility, the body consumes protein anyway by cannibalizing muscle tissue. Unlike proteins, the metabolism of carbohydrates and fats, to a certain extent, contribute to body water stores up to twelve to seventeen ounces per day depending on the type of diet. Furthermore, the metabolism of protein produces a higher metabolic rate, thus using more energy and creating more heat. Use common sense and adapt to your particular situation. Proteins are a wonderful thing in cold, low-elevation environments with plenty of available drinking water.
As already mentioned, if your survival situation goes long term, survival rations, in their truest sense, should not be considered substitute meals. Their main focus is to provide the survivor with sugar in order to minimize catabolism and dehydration in order to increase survival time. Ideal survival foods, provided there's adequate water to drink, consist of mostly fats and carbohydrates. While fats are packed with calories they take time for the body to metabolize into the simple sugars or glucose required for energy. In addition, fats are not well-tolerated as an energy source at high altitudes. If you live at altitude, store extra carbohydrates in the place of some fats and proteins, as carbohydrates are already partially oxidized and thus require less oxygen from the body—up to 8 to 10 percent less—to convert into energy.
More than any other nutrient except water, a reduced carbohydrate intake depletes muscle glycogen stores, decreasing your endurance
. For short-term survival (one to three days), a lack of calories is not nearly as important for performance as a lack of carbohydrates. Simple sugars and carbohydrates provide fast energy as they metabolize very quickly and are required for the body to be able to access its stored fat deposits. For the long term, however, if not accompanied by certain complex carbohydrates and proteins for stabilization, this quick source of energy leaves your body just as quickly, resulting in the infamous "sugar crash."
The
Glycemic Index
(GI) was developed in 1981 and is a numerical system for measuring how fast carbohydrates in various foods trigger a rise in blood sugar or glucose. Foods containing high amounts of fats and proteins don't cause blood sugar levels to rise nearly as much as those containing carbohydrates. In essence, the higher the GI number, the greater the blood sugar response. In general, a GI of 70 or more is high, 56 to 69 medium, and 55 or less is low. Until the early 1980s, scientists assumed that only digested simple sugars produced rapid increases in blood sugar levels. In truth, many simple sugars don't raise glucose levels any more than some complex carbohydrates, as not all carbohydrates act the same when digested. Foods producing the highest GI response include several starchy staples that folks commonly eat including breads, breakfast cereals, and baked potatoes. Even table sugar is low on the GI list in comparison. Lowglycemic foods include beans, barley, pasta, oats, various types of rice, and acidic fruits among others.
Consuming food with a high GI will cause your blood sugar to go through the roof. In response, your pancreas releases insulin in an attempt to combat your body's rising sugar levels. Ingested proteins contain
glucagons
that swim around the bloodstream trying to stabilize the blood sugar, helping to prevent the crash your body experiences by consuming simple carbohydrates or sugars alone.
In summary, the three macronutrients found in foods—proteins, fats, and carbohydrates—contain different amounts of calories and metabolize at varying rates within the body. The savvy survivor should store foods containing all three macronutrients. In addition, it would be wise to have on hand a one-size-fits-all, portable, quick, no-cook combination food source containing simple sugars and carbohydrates that jump-starts the body's glucose levels immediately. This same food source should also possess longer-burning carbohydrates for short-term energy and fats for sustained, long-burning energy. Proteins, with thought given to their disadvantages, should be present as well, thus stabilizing simple sugars and carbohydrates, helping to prevent the "crash," as well as providing the body with extra, long-burning fuel.
Foods including all macronutrients will give you the greatest bang for your buck, metabolizing in succession sugars, carbohydrates, proteins, and finally fats. Native American people knew the advantage of combining foods for maximum energy and performance all too well as their rugged lifestyles demanded the most from their bodies. They developed "pemmican," a staple that possessed all three macronutrients: berries for simple sugars and carbohydrates, meat for protein, and fat for fat. All three elements were prepared and mixed together to create the ultimate indigenous trail mix.
Your Basal Metabolic Rate [BMR]: Defining How Much Feed You Truly Need
Your
basal metabolic rate
(BMR) is the amount of calories you burn at rest doing absolutely nothing. It is the bare minimum number of calories or energy your body needs to sustain the life process: respiration, circulation, cellular metabolism, glandular activity, and the maintenance of core body temperature. BMR requirements vary widely based on age, sex, muscle and bone weight, and height, so pinning down how much calories you burn sitting on your butt can be a challenge. The four main physiological factors that influence the burning of calories for BMR are as follows:
1
Being male
. Men and boys burn more calories simply being men than women do being women.2
Your age
. Young people burn far more calories than middle-aged or older folks.3
Muscularity
. More muscles require more nutrients, even at rest.4
Tall people
. The more body one has, excluding fat, the more nutrition is required to keep the body idling.
