What is industrial food, and why is it so bad?
How did our food get so bad? Ironically, the catastrophic decline in food quality began more than 200 years ago with breathtaking improvement.
The Industrial Revolution, which would transform the lives of billions, was really a ries of smaller, mutually reinforcing revolutions: The industrial energy revolution, the industrial transportation revolution, the industrial chemicals revolution, and so on. One of the was the industrial food revolution.
From around 1800 to about 1950, all of the major food problems that had plagued mankind for centuries were largely solved by industrialization, at least for people in the minority of countries that industrialized during this period. Famine, food-borne illness, lack of food variety, basic nutritional deficiencies among the poor and other problems were largely eliminated for millions.

Agriculture machinery, chemicals, railroads and trucks, factory asmbly lines, refrigeration, pasteurization, sterilization and other industrial-revolution innovations drove down the cost of food, and incread nutritional safety and variety. Lower food costs, plus supermarkets and houhold appliances meant people no longer had to spend most of their time paying for, acquiring or preparing food. Combined with advances in medicine, lives became longer, healthier and better.
So what happened between 1950 and today?
The industrial food revolution turned food into a product. Like all consumer products, food now had to constantly evolve into something "better," cheaper and faster. This evolution involved gradual changes in the actual biochemistry of what we're putting in our mouths. But while the food keeps changing, our bodies don't. With each passing year, the food supply becomes less compatible with human biology.

桂林历史One of the many fal assumptions about industrial food is that, well, food is food, and it doesn't matter if a computer-controlled machine mixes the raw ingredients together in a factory or a cook does in a kitchen. What's the difference? The difference is not the mixing, but the myriad changes made to the food to optimize it for the overall industrial process.
Most foods are "modified" or "procesd" at some point. The question that parates industrial from traditional foods is the purpo of tho modifications. Traditional modifications tend to improve the taste, health qualities, digestibility and long-term storage of foods. Grains are modified to make bread, for example. Olives are procesd into olive oil. The food is altered to make it more edible, nutritious and desirable, as well as storable.
The highest purpo of industrial processing is to lower the cost of food. Consumers favor cheaper food, so food companies compete to find new ways to lower costs. Just lik
e computer software or cars or any other industrial product sold in the competitive marketplace, there has been constant innovation in industrial food processing to drive down costs. Low cost is achieved by optimizing absolutely every aspect of food manufacturing, including eds, soil, farm equipment, harvest schedules, trucks, factories, additives, process, packaging and more. Another strategy for lowering costs is to offshore the production and processing of foods to China or other countries with low production costs and lax food-safety regulations, or simply buy the ingredients from Chine companies.
大鲅鱼Modifications to food begins before eds are even planted. The first part of the industrial-food process is the lection of raw ingredients. Almost every food type originated with massive variety -- literally thousands of species of, say, apples or wheat. But industrial processing tends to favor only one or a small number of species, which have been heavily hybridized, cultivated or genetically modified to make them better for modern food processing systems. If you buy an apple pie at the store, it's made from single modern species of apples and wheat that didn't even exist 200 years ago.

Industrial processing and mass marketing dictates ingredient lection choices. Modern wheat is favored for bread-making over other grains becau of its higher yield, machine thresh-ability, super high gluten content and other reasons. Specially bread dairy cows are favored over, say, goats, becau they produce a lot more milk and can be feasibly kept in pens and a host of other reasons amenable to mass industrial processing, even though goat milk is far more compatible with the human digestive system. Corn and soy are chon as the universal "fillers" for procesd foods, becau they're super cheap to grow, in part becau growers receive government subsidies to grow them.

The most extreme modifications are made in the lab. Biotech company scientists custom-tailor the genetics of eds in ways that ud to be only science fiction. Fish genes are grafted into strawberry DNA to reduce crop loss from frost, for example. Corn and potatoes are altered to manufacture their own toxic pesticides. Many of the designer crops are created to be wholly dependent upon a specific brand of herbicide or incticide. Produce has also been hybridized and genetically modified for uniformity, blemishlessness, durability for transportation and other qualities that boost the salability o
f food. As with all industrial food innovations, the crops have been transformed into a better product to ll, and not a better food to eat. And they look better to the uniformed consumer than organic produce, with its blemishes and variable shapes and sizes.
