Harm of Fast Food on The Body

The harm of fast food: Most people eat junk food. According to the Food Institute’s analysis of data released by the Bureau of Labor Statistics, many people from different countries of the world spend 45 percent of their budget dollars eating out.

Compared to 40 years ago, families in many countries of the world, especially America, now spend half of their food budget on restaurant food. In 1977, they spent just under 38 percent of family food budgets eating out.

Eating out can affect your health. Continue reading the article to learn more about the harms of fast food on your body.

The effect on the digestive system and the heart

Most fast food, including drinks, is loaded with carbohydrates with little or no fiber.

When the digestive system breaks down these foods, carbohydrates as glucose (sugar) are released into the bloodstream. As a result, blood sugar increases.

The pancreas responds to the high level of glucose by releasing insulin. Insulin transports sugar throughout the body to cells that need it for energy. As your body uses or stores sugar, your blood sugar returns to normal.

Your body regulates your blood sugar, and as long as you are healthy your organs can handle these sugar spikes properly. But eating large amounts of carbohydrates frequently can lead to frequent spikes in blood sugar.

Over time, this insulin spikes may cause the body to respond to natural insulin to vibration. This increases the risk of insulin resistance, type 2 diabetes, and weight gain.

Sugar and fats

Many fast foods contain sugar. Not only does this mean extra calories, but also less nutrition. The American Association (AHA) suggests eating only 100 to 150 calories of added sugar per day. That’s about six to nine teaspoons.

Many fast food drinks alone contain over 12 ounces. A 12-ounce can of soda contains 8 teaspoons of sugar. This equals 140 calories, 39 grams of sugar.
Trans fats are the processed fats that are created during food processing. They are most commonly found in:

  • Fried pancakes.
  • Pastries.
  • Pizza dough.
  • Crackers.
  • Biscuits.

No amount of trans fats is good. Eating foods that contain trans fats can increase bad cholesterol (LDL), decrease good cholesterol from the body, and increase the risk of developing type 2 diabetes and heart disease.

Restaurants may also exacerbate the calorie counting problem. In one study, people who eat at restaurants they deemed “healthy” still reduce the number of calories in their meal by 20 percent.


The combination of fat, sugar, and lots of sodium (salt) can make fast food tastier for some people. But a diet high in sodium can lead to water retention, which is why you may feel bloated or swollen after eating junk food.

A diet high in sodium is also dangerous for people with blood pressure conditions. Sodium can raise blood pressure and put pressure on your heart and cardiovascular system.

According to one study, about 90 percent of adults underestimate the amount of sodium in their fast food.

Keep in mind that the AHA recommends that adults eat only 2,300 milligrams of sodium per day. One fast food meal can be half the value of your day.

The effect on the respiratory system

The extra calories from fast food can cause you to gain weight. This may lead to obesity. Obesity increases the risk of developing respiratory diseases, including asthma and shortness of breath.

Excess weight can put pressure on your heart, and lungs and symptoms may appear even with little effort. You may notice difficulty breathing while walking, climbing stairs, or exercising.

For children, the risk of respiratory problems is especially clear. One study found that children who ate fast food at least three times a week were more likely to have asthma.

The effect on the reproductive system

Ingredients in fast food may affect your fertility. One study found that processed foods contain phthalates. Phthalates are chemicals that can interrupt how hormones in your body work.

Exposure to high levels of these chemicals can lead to reproductive problems, including birth defects.

Impact on the cerebral system (skin, hair, and nails)

The junk food you eat affects the appearance of your skin, but it may not be the foods you suspect.

Chocolate and greasy foods like pizza were to blame for the acne.

Foods rich in carbohydrates lead to high blood sugar, and these sudden spikes in blood sugar levels may lead to acne.

A study suggests that children and teens who eat fast food at least three times a week are more likely to develop eczema. Eczema is a skin condition that causes irritated patches of inflamed skin.

Harm of fast food: the effect on the skeletal system

Increase your intake of carbohydrates and sugar in fast food and acid-processed foods in your mouth. These acids can break down tooth enamel. As tooth enamel disappears, bacteria can take hold, and cavities may develop.

Obesity can also lead to complications of bone density and muscle mass. People who are obese have a higher risk of bone falling and breaking. It is important to continue exercising to build the muscles that support your bones, and to maintain a healthy diet to reduce bone loss.

Harm of fast food on society

Today, we consider over 2 in 3 adults in the United States obese. And we consider more than a third of children between the ages of 6 and 19 overweight.

Fast food consumption in various parts of the world, especially in America, appears to coincide with the growth of obesity.

Despite efforts to raise awareness and make people aware of the harms of fast food, one study found that the amount of calories, fat and sodium in fast food has not transformed.

With food intake more and more frequent, it can have adverse effects on the health care system of individuals.
