Science The Future under the Magnifying Glass Mani Samani Contributor Fo" single pills providing a day's nutrition to bubble gum that serves you a three-course dinner, bite-sized food replacements have been present in fiction for a long time and the fuss alll started with the suffragette. Food innovations have created every manner of better eating through chemistry. But why don't we have food pills, which would solve problems ranging from world hunger to messy kitchens? Today there are pills to provide the vitamins we need, which leaves just the pesky issue of caloric intake. Although an adult typically needs about 2000 calories per day, the question is why even the most concentrated source (pure fat) can't make that many calories fit into a single pill? Dr. Stephen Rader, bio-chemistry professor at UNBC, answered some questions: Can we make energy available to our bodies without using food? This is an interesting question. If you have a pill that you could take to replace food, this would be presumably “‘Lhaven't got it quite right yet. -Willy Wonka convenient because then instead of having to cook to make food and buying things you just take a pill. What we are really talking about is energy density, so the most energy rich food that we have now is things like fats and oils. Butters for example, have the most energy per unit volume in unit weight. So is it possible fo pack more than that into a smaller volume? Certainly for other processes there is much denser form of energy. For example, you can generate energy by burning wood, but wood doesn't have much energy in per unit weight in unit volume. It is much more efficient to use the efficient of uranium. There is an example that there is a huge difference in scale that you can operate on and how much energy you can get from a little bit of uranium vs. a little bit of wood is many orders of magnitude ditference. But our bodies are really only able to use limited number of things and | don't know any way to pack those in smaller volumes. So | would have to say no. Would it be able to solve hunger problems? If you are providing all of the necessary Part 3: Replacement Pills vitamins and micronutrients in pil form, then the only other thing that you need is calories, the actual energy that keeps your body running, so in principle then you could make something that is cheap and easily available and you would give it to everybody and you would supplement that with vitamins that you would normally get by eating a range of fruits and vegetables. But can you really live off of the things we get from food, like fatty acids and carbohydrates, without eating actual foode Dr. Mamdouh Shubair, assistant professor of nutrition and food studies at UNBC claims that it's probably not the best idea. “The matter is satisfactory, if you don't eat food there is no way to have that satisfaction that comes from enough food when you are happy while eating. In the case of pills it actually doesn't replace foods. So pills give you the basics of our bodies’ needs but you cannot live on pills.” He says the problem of switching from food to blended shakes containing all the nutrients and micronutrients humans are known to need is that you are not certain about whether nutrients in the shakes are natural or made of chemicals. A few years ago, a man actually spent a week eating nothing but monkey chow and recorded the experience on Youlube called “Monkey Chow Diaries.” Not even halfway through, he was almost manic with cravings for hot food. The repetitious, barely satisfying nature of the diet made him depressed and irritable, and he joked about acquiring monkey-like characteristics- namely, the desire to scream at people and throw poop. To recapitulate, There's no way we know of to achieve Willy Wonka's dream of swallowing a pill that tastes like a blueberry pie, and makes a person feel as satisfied as eating a real one.
