Food Processing and Ultra Processed Food

What is processed and ultra processed food. Advantages and Disadvantages.

Definitions

What does food processing mean?

According to the Department of Agriculture, processed food are any raw agricultural commodities that have been washed, cleaned, milled, cut, chopped, heated, pasteurized, blanched, cooked, canned, frozen, dried, dehydrated, mixed or packaged — anything done to them that alters their natural state. This may include adding preservatives, flavors, nutrients and other food additives, or substances approved for use in food products, such as salt, sugars and fats.

Benefits of Food processing

The important benefits of food processing include:

  1. Food processing reduces the number of harmful bacteria in food that can cause diseases. For eg., drying, pickling dehydrates the food product and alters the pH that prevents the growth of harmful microorganisms.
  2. It also improves the shelf-life of food products.
  3. It reduces health inequalities and major health concerns.

Drawbacks of Food Processing

The important drawbacks of food processing include:

  • Processed food contains artificial ingredients.
  • A large number of resources are spent in making the food pleasant to the brain that leads to overconsumption.
  • Processed foods are the biggest source of added sugar that is very unhealthy.

Additional Information

Unprocessed or minimally processed foods

Unprocessed foods include the natural edible food parts of plants and animals. Minimally processed foods have been slightly altered for the main purpose of preservation but which does not substantially change the nutritional content of the food. Examples include cleaning and removing inedible or unwanted parts, grinding, refrigeration, pasteurization, fermentation, freezing, and vacuum-packaging. This allows the food to be stored for a greater amount of time and remain safe to eat. Many fresh fruits, vegetables, whole grains, nuts, meats, and milk fall into this category.

Processed culinary ingredients

Food ingredients derived from a minimally processed food by pressing, refining, grinding, or milling. They are typically not eaten on their own but used to prepare minimally processed foods. Examples include oils from plants, seeds, and nuts, or flour and pastas formed from whole grains.

Processed foods

Foods from either of the two previous groups that have added salt, sugar, or fats. Some canned fruits and vegetables, some cheeses, freshly made bread, and canned fish are examples. These foods usually are made from at least 2-3 ingredients and can be readily eaten without further preparation.

Fortified foods contain vitamins and minerals that are added after processing. Either these nutrients were lost during processing, or they were added because they are lacking in the average diet. Examples include B vitamins (riboflavin, niacin, niacinamide, folate or folic acid), beta carotene, iron (ferrous sulfate), vitamin C (ascorbic acid), Vitamin D, or amino acids to boost protein content (L-tryptophan, L-lysine, L-leucine, L-methionine).

Ultra-processed foods

Also commonly referred to as “highly processed foods,” these are foods from the prior group that go beyond the incorporation of salt, sweeteners, or fat to include artificial colors and flavors and preservatives that promote shelf stability, preserve texture, and increase palatability. Several processing steps using multiple ingredients comprise the ultra-processed food. It is speculated that these foods are designed to specifically increase cravings so that people will overeat them and purchase more. They are typically ready-to-eat with minimal additional preparation. Not all but some of these foods tend to be low in fiber and nutrients. Examples are sugary drinks, cookies, some crackers, chips, and breakfast cereals, some frozen dinners, and luncheon meats. These foods may partially if not completely replace minimally processed foods in some people’s diets. One study using data from the U.S. National Health and Nutrition Examination Survey found that ultra-processed foods comprised about 60% of total calories in the U.S. diet. An association has been suggested between the increasing sales of ultra-processed foods and the rise in obesity.

Ingredients used widely in the production of highly/ultra-processed foods such as saturated fats, added sugar, and sodium have become markers of poor diet quality due to their effect on heart disease, obesity, and high blood pressure. It is estimated that ultra-processed foods contribute about 90% of the total calories obtained from added sugars.

  • If the food is highly processed, it may contain several food additives such as artificial colors, flavors, or preservatives. Their ingredient names may be less familiar. Some preservatives promote safety of the food by preventing growth of mold and bacteria. Others help prevent spoilage or “off” flavors from developing. Examples that you may see on the label include:
    • Preservatives—ascorbic acid, sodium benzoate, potassium sorbate, tocopherols
    • Emulsifiers that prevent separation of liquids and solids—soy lecithin, monoglycerides
    • Thickeners to add texture—xanthan gum, pectin, carrageenan, guar gum
    • Colors—artificial FD&C Yellow No. 6 or natural beta-carotene to add yellow hues

These 10 companies, known as the “Big Ten,” are Nestlé, PepsiCo, Coca-Cola, Unilever, Danone, General Mills, Kellogg’s, Mars, Associated British Foods and Mondelez. Each of these companies employs thousands and make billions of dollars in revenue every year, while virtually controlling the world’s food supply.

Many of these companies are household names, as they often spend massive amounts on advertising in an effort to promote their brands. Out of these companies, nine of the ten were among the 100 largest purchasers of media advertising in the world in 2012. Coca-Cola, the world’s sixth largest advertiser, spent more than $3 billion in 2012 on advertising. Unilever’s media expenditure, at $7.4 billion, was the second-highest worldwide.

Essentially, these companies work to propagandize the public into a sense of familiarity through advertising, in an effort to keep people buying their “food-like” products. Across western society, and specifically in the United States, most of what we buy is what environmental and food advocate Michael Pollan deems “edible, food-like substances.”

Typically, “food-like” items come from a guy in a white lab coat, rather than from nature, and these products are not good for your body, or your health. It is important to remember that the “Big 10” specialize in edible “food-like” products that come from a lab and you should do your best to steer clear of them.

While “food-like” products may not be extremely harmful when used infrequently, it is important to remember that these products often contain unhealthy trans fats, high levels of sodium, hydrogenated oils and refined sugar, especially high fructose corn syrup. All of these things have been linked to one or more chronic diseases. In addition, many processed foods are much lower in vitamins and minerals but much higher in calories than whole foods.

PepsiCo Although calling Pepsi-Cola a "food" is disputable, PepsiCo reaches far beyond the world of soft drinks. The company has come a long way since its founding in 1898. PepsiCo brought in $44.3 billion in revenue last year. The company owns both the Gatorade and Propel brands of sports drinks, as well as Mountain Dew and SoBe beverage brands.

But more surprising, PepsiCo owns Frito-Lay, which produces an enormous variety of snack foods, including Ruffles, Lay's, Tostitos and Fritos brands. Healthier eaters might be surprised to find out that Pepsi owns Tropicana, some lines of the TAZO juice and tea brand and Quaker - which produces such wholesome foods as oatmeal, Mother's cereal and puffed wheat. And if you're curious who's winning the long-fought cola war - Coke or Pepsi - the Coca-Cola Company raked in just $31 billion in 2009.

Dole Food Company can pat itself on the back: It is the world's largest producer of fruit and vegetables. In 2009, the company saw revenues of approximately $6.8 billion, which is a far cry from its modest beginnings in Hawaii back in 1851. Missionaries Samuel Northrup Castle and Amos Starr Cooke founded Castle & Cooke, and they invested in seafood packing, railroad production and shipping initiatives. That company acquired James Dole's Hawaiian Pineapple Company and the Standard Fruit Company by the 1960s.

After Castle & Cooke was spun off in 1995, the produce giant moved its headquarters to Westlake Village, California. Now, Dole operates plantations all over Central America, South America and the Philippines, producing everything from bananas to pre-packaged salad mixtures to fruit cups.

Minnesota's General Mills has its fingers in a large variety of food brands - so many, in fact, that the company made a tidy $14.7 billion in sales last year. Founded in 1856, it was originally known as the Minneapolis Milling Company and didn't acquire its current name until 1928. Since then, the company has made acquisitions in clothing stores, restaurants and toys; although, it now focuses primarily on food production and marketing.

General Mills likely owns some of your favorite brands, including Betty Crocker, Pillsbury, Yoplait and Green Giant. On top of that, the conglomerate has ventured into the natural and organic food industry and owns Cascadian Farm, Muir Glen and Lärabar - a health-bar without gluten, soy or dairy.

Nestlé When it comes to packaged foods, you can't get any bigger than Nestlé. Although its origins are found in Switzerland, the company has become the largest packaged food company in the world, and you'd be hard-pressed to not find a Nestlé product in nearly every kitchen in the nation. The company's revenue reached $110 billion last year, and you can bet all that money didn't come from selling just chocolate milk mix.

Nestlé's American brands are wide-ranging, from the candy you would expect (Gobstoppers, Pixy Stix and Laffy Taffy) to coffee (Nescafé and Taster's Choice). The company has also made a surprising number of acquisitions in the frozen pizza category, owning Digiorno, California Pizza Kitchen, Hot Pockets, Lean Pockets and Tombstone.

Kraft Foods While Nestlé reigns king of the international food scene, Kraft holds the title for largest food company headquartered in the United States. Northfield, Illinois is the home of this food giant, which brought in $40.4 billion in revenues last year. The company was started in 1923, and its focus was originally on ice cream products. The company later expanded into a full range of dairy products.

Now, Kraft offers a seemingly endless range of food products. If PepsiCo has a monopoly on chips and Nestlé has a firm grip on frozen pizza, then Kraft knows its crackers: Wheat Thins, Triscuits, Ritz, Nabisco and Cheese Nips are all owned by the company. But much like its counterparts, Kraft has also made inroads in the health, diet and upscale food industries. They market South Beach Living meal replacement bars, Boca meatless products, and Grey Poupon.

Health Risks of Heavily Processed Foods

There are many potential health effects of ultra processed foods, including:

  • Increased cancer risk. A five-year study of over 100,000 people found that every 10 percent increase in consumption of ultra processed food was associated with a 12 percent higher risk for cancer.

  • Too much sugar, sodium and fat. Heavily processed foods often include unhealthy levels of added sugar, sodium and fat. These ingredients make the food we eat taste better, but too much of them leads to serious health issues like obesity, heart disease, high blood pressure and diabetes.

  • Lacking in nutritional value. Heavy processing strips many foods of their basic nutrients, which is why many foods today are fortified with fiber, vitamins and minerals.

  • Calorie dense and addicting. It’s very easy to overindulge in unhealthy food and consume more calories than we realize. For example, an Oreo cookie contains about 50 calories, while an entire cup of green beans is only 44 calories. Processed foods like these are also designed to stimulate our brain’s “feel-good” dopamine center, making us crave more of them in the future.

  • Quicker to digest. Processed foods are easier to digest than unprocessed, whole foods. That means our bodies burn less energy (hint: calories) digesting them. It’s estimated we burn half as many calories digesting processed foods compared to unprocessed foods. This fact combined with the calorie density of processed foods in general can make it easy to pack on the pounds.

  • Full of artificial ingredients. There are about 5,000 substances that get added to our food. Most of them have never been tested by anyone other than the company using them. That includes additives to change color, texture, flavor and odor as well as ingredients like preservatives and sweeteners.
