The Biggest Problem With Processed Foods

Although you may think you can identify a processed meal when you see one, almost everything you buy at the grocery store has been through some sort of processing, including blanching, canning, drying, or pasteurization. Put another way, a food item is considered processed if there has been any alteration from its original state to its final state on a shelf.

There are ultra-processed foods, though. Both canned sausages and frozen chopped spinach are processed, but the latter has been processed far more than the former. From field to table, ultra-processed foods travel through an industrial process.

This frequently involves processes like hydrolysis, which improves taste, and hydrogenation, which creates semisolid oils. A range of chemicals are also included in these foods to assist bind the ingredients together, extend their shelf life, or improve their taste.

According to some estimates, roughly 60% of the daily calories consumed by adults in the United States come from ultra-processed foods. Children and teenagers suffer more because over 70% of their diet comprises ultra-processed foods.

However, an increasing amount of research has connected consuming more ultra-processed foods to a host of negative health outcomes, and scientists are only now starting to figure out why.

What are Ultra-Processed Foods?

In contrast to moderately processed meals such as frozen fruits or canned vegetables, ultra-processed foods (UPFs) go through several industrial processes and are packed with additives. These foods are manufactured in factories and are laden with artificial chemicals, harmful fats, and added sugars.

1. Raw or barely processed: Nutrients and vitamins found in whole foods such as fruits, vegetables, and raw nuts are retained. Techniques like pasteurization and freezing guarantee safety without causing major changes.

2. Processed: Although these foods go through some processing, they usually have two or three more components, including sugar, salt, or oil. Freshly baked bread or tinned salmon are two examples.

3. Ultra-processed (UPF): Foods are those associated with potentially dangerous health effects. They are highly processed and frequently include a large list of chemicals, including artificial coloring, bad fats, added sugars, and preservatives. Consider packaged snacks, sugary drinks, frozen dinners, and a variety of fast food items.

What distinguishes Ultra-Processed Food from Conventionally Processed Food?

What precisely qualifies as highly or extremely processed food, and why are they deemed unhealthy?

Ultra-processed foods undergo significant changes intended to improve flavor, texture, or shelf life, whereas some processed foods may go through preservation procedures to retain their nutritional content and freshness. Typically, artificial components and industrial processes that are far apart from conventional cooking procedures are used in this manufacturing process.

In addition, popular chemicals like artificial sweeteners and emulsifiers are often added to ultra-processed foods, which usually have very little whole food in them. When taken frequently, this significant reliance on additives, along with the excessive levels of fat, sugar, and salt, not only reduces the nutritional value of these goods but also poses serious health hazards.

Sugar-filled drinks, packaged snacks and sweets, and ready-to-eat meals are common examples of highly processed cuisine. It is most likely extremely processed if it can be kept on the shelf for a lengthy period without going bad!

Are Foods With Ultraprocession Harmful For Your Health?

There is some evidence to support the widespread belief that consuming highly processed food will result in weight gain or several other health problems. Although a clear cause for harm has not been found, research has linked the consumption of ultra-processed foods to a host of health issues, including obesity, type 2 diabetes, certain malignancies, cardiovascular disease, and even mild melancholy and anxiety.

The first study to demonstrate a cause-and-effect relationship between eating ultra-processed meals and weight increase came out in 2019. Twenty healthy volunteers were kept in a ward at the National Institutes of Health Clinical Center in Bethesda, Maryland, and given a random diet consisting of either minimally processed or ultra-processed food for two weeks, after which they were switched to the other diet. 

A person on the ultra-processed diet, for instance, would begin the day with items like turkey sausages, croissants, and boxed cereal along with a blueberry muffin or muffin. Instead, a person following a minimally processed diet might have a fresh omelet and sweet potato hash, or Greek yogurt and berries.

Those following an ultra-processed diet consumed almost 500 more calories a day on average than those following a lightly processed diet. After two weeks, participants in the previous group gained roughly two pounds and continued to eat more quickly. 

Participants lost almost the same amount of weight on the minimally processed diet as they gained on the processed diet by eating fewer calories. In both conditions, subjects were allowed to consume as much as they pleased and had access to almost twice as many calories as they required.

What Makes Us Favourable To Ultra-Processed Foods?

Researchers are still unsure of the exact reasons behind people's preference for highly processed foods. According to Hall, one theory is that their concoction of substances may make it impossible for us to resist. When was the last time you ate just one chip from a bag? It's quite difficult to resist eating more.

To investigate the impact on energy intake, Hall 2021 compared a high-carb diet with a low-carb diet. Individuals tended to consume more calories when served meals that were heavy in fat and sugar, fat and salt, or carbs and salt, he claims. Hall continues, "These foods are known to be hyper-palatable."

These foods include a combination of fat, salt, or sugar "that would never exist in nature," according to Juul; in other words, they have artificially boosted palatability that surpasses the palatability any ingredient could provide on its own. Diets containing both fat and carbohydrates activate the brain's reward system more effectively than diets containing just one of those components, according to an earlier study. Additionally, compared to the minimally processed diet, the ultra-processed meals in Hall's study had more calories per bite.

Certain meals may be addictive, according to certain scientific theories. While eating bananas doesn't cause people to lose control, consuming highly processed foods causes them to exhibit all the symptoms of addiction, according to Ashley Gearhardt, a psychology professor and nutritionist at the University of Michigan. 

The brain's pleasure center, the striatal dopamine system, is stimulated by addictive drugs by causing a dopamine spike that is quickly followed by a sharp decline. According to Gearhardt, "It's like a quick hit that isn't sustainable." Ultra-processed meals have a brain-mimicking impact similar to that of ethanol and nicotine.

According to Gearhardt, "That makes sense because the need to obtain calories really shaped the brain's reward system." She adds there are several possible causes for the addictive component in food, including taste, scent, sugar, fat, and additives. 

Similar to other addictive substances, discontinuing the consumption of ultra-processed foods has been proven to cause withdrawal symptoms in animals, including agitation and anxiety.

The Dangers of Highly Processed Food for Your Health

Ultra-processed foods may be deficient in dietary fiber and low in vitamins and minerals. It may hurt you in the ways listed below:

1. Elevated Chance of Obesity

Ultra-processed foods have been connected in research to a higher risk of obesity, heart disease, and other illnesses. 

The high calorie, fat, sugar, and sodium content of ultra-processed foods can lead to weight gain and obesity. According to a study that was published in the journal Cell Metabolism, limiting ultra-processed meal intake may be a helpful tactic for treating and preventing obesity.

2. Nutrient Deficiencies

Foods that have undergone extreme processing frequently lack vital vitamins and minerals, which can lead to shortages of vital elements like protein, fiber, calcium, iron, and B vitamins. 

The increasing use of UPF has been highlighted in recent research that has been published in esteemed medical journals like Lancet Gastroenterology & Hepatology, Lancet Endocrinology, and the British Medical Journal. These studies view this as a global concern.

3. Inadequate Digestion

Foods that have undergone extreme processing frequently include preservatives and additives that might impede the body's normal digestive function and cause problems including gas, bloating, and constipation.

An increasing consumption of highly processed foods is linked to a higher risk of irritable bowel illness, according to a study published in the British Medical Journal.

4. Heart Conditions

Because ultra-processed foods are often heavy in cholesterol and saturated fat, which can clog arteries and cause a heart attack, eating too many of them can increase the risk of heart disease.

A study that was published in the international journal Advances in Nutrition suggests that eating a lot of highly processed food may make heart disease more likely to occur.

5. Diabetes

Consuming an excessive amount of ultra-processed foods might also raise your risk of type 2 diabetes because they are typically heavy in calories and sugar. Regularly consuming an excessive amount of added sugar might cause compulsive overeating since it can quickly elevate insulin levels. It is also linked to inflammatory diseases, metabolic syndrome, and type 2 diabetes.

6. Cognitive Decline

A Neurology journal study that included more than 72,000 participants in the UK found a connection between ultra-processed food consumption and dementia. Approximately one in every 120 individuals in the group consuming the most highly processed meals experienced dementia during a ten-year study. 

It is recommended that people who want to get healthier consume less highly processed foods and more whole, unprocessed foods. The best method to make sure your body is getting the nutrients it needs is to eat a diet high in fruits, vegetables, whole grains, and lean proteins.

Conclusion

Food processing encompasses a wide range of techniques, from straightforward procedures like chopping or freezing, to complex processes like transforming ingredients into a finished food product. It's a complex topic because it has both intentional and unexpected repercussions. 

There are numerous methods for processing food and combining ingredients, therefore the finished products might range greatly and have potential dangers or benefits for health. Processed foods are best consumed in moderation because they are high in calories, high in saturated fat, added sugar, or salt, and may have less fiber. 

For more details or recommendations on how to incorporate processed foods into a sustainable and healthful diet, it can be helpful to compare the food labels and consult your country's dietary requirements.

Here are some helpful pointers to remember to help you make good food choices and navigate the food environment:

1. Consume a wide range of plant foods, such as fruits, vegetables, legumes, and so on.

2. Select whole grains instead of processed ones.

3. Eat more nutrient-dense foods and less fat, sugar, and salty meals and beverages; you can find these by reading the nutrition label!

4. Swap out saturated fats for unsaturated ones.

5. Consume minimal or no processed meats, such as cured, fermented, salted, or smoked meat.

6. Aim for portion control and mindful eating.
