Why Does Fast Food Make Me Feel Sick? 17 Effects

Why does fast food make me feel sick? I feel sick after eating fast food because of the high fat and sodium content.

The low fibre levels also cause the blood sugar to spike, which leads to an increase in insulin production. This causes my triglycerides and cholesterol levels to rise and my energy levels to drop.

Fast foods also lack any nutrients and micronutrients that will help me feel good over the long term. Eating fast food regularly could lead to long-term health problems.

17 Effects, Why Does Fast Food Make Me Feel Sick:

1. Your Body’s Natural Ability to Regulate Glucose, Insulin and Other Hormones

Sugar is addictive because it causes large amounts of insulin to be released. Insulin lowers your blood sugar level, which increases cravings for sugary foods. If you eat these foods frequently, especially combination foods that contain both fat and sugar, you can overload your system, causing weight gain that leads to insulin resistance.

2. Your Brain’s Ability to Regulate Appetite and Energy Levels

Sugar competes with the amino acid tyrosine for absorption. This affects your brain chemistry, which impacts mood stability, thyroid function, insulin levels and other hormones. High-sugar intake has been linked to anxiety, panic attacks, depression and fatigue.

3. The Gut-Brain Connection

The vagus nerve is the primary nerve that controls unconscious body functions such as heart rate, digestion, breathing rate and blood pressure. The vagus nerve is affected by the foods you eat. For example, when the bacteria in your gut receive refined sugar, they communicate to your brain that it should release more insulin because something dangerous has entered your bloodstream. The loss of communication between the gut and the brain can lead to increased inflammation and an elevated heart rate long after you’ve consumed fast food.

4. Blood Flow to the Brain

If you eat too much sugar or high-glycemic foods, your blood flow will decrease, which causes a loss of brain tissue function and damage. According to Dr Gary L. Wenk, professor of psychology and neuroscience at The Ohio State University in Columbus, “Sugar can disrupt your memory and make you less intelligent.”

5. The Ability of Your Brain to Make Serotonin

Serotonin is a neurotransmitter that helps regulate many of our moods. For this reason, serotonin-depleted brain cells can lead to depression, low energy and carb cravings. Low serotonin levels are also associated with weight gain around the middle section of the body.

6. Your Ability to Make Dopamine

Dopamine is another neurotransmitter that affects your moods and motivation level. Low dopamine levels may lead you to seek out high-sugar foods that give an instant boost of dopamine.

7. Your Liver’s Ability to Detoxify

When you eat a hamburger, microorganisms that live in meat can enter your bloodstream and travel to your liver. Once there, they cling to the delicate cells that line your liver’s blood vessels. When these microorganisms die, they release their toxic chemicals into the cells of your liver. This causes inflammation, which leads to scarring and cellular malfunctioning.

8. Fast Food Your Heart Rate

Your heart rate is directly related to your breathing. If you breathe rapidly, your heart beats faster. The chemicals formed by fast foods’ high-fat and high-sugar content can affect brain neurotransmitters that could trigger rapid breathing. This also puts stress on your heart by increasing your blood pressure and changing the composition of your red blood cells.

9. Fast Food Your Blood Pressure

If you eat fast food multiple times a week, your blood pressure could increase over time. A diet high in sugar and saturated fat can lead to higher triglycerides and lower HDL levels, risk factors for heart disease.

10. Fast Food Affects Your Cholesterol

The high-fructose corn syrup in most fast-food items can raise triglycerides and lower your high-density lipoprotein (HDL) or healthy cholesterol levels. A study published in the journal Nutrition Research found that people who eat a lot of junk food have higher total cholesterol, LDL cholesterol and triglyceride levels than people who do not eat fast food.

11. Fast Food Affects Your Immunity

If your immune system is constantly activated, you can become depressed and tired more easily. This happens because the body has to work harder to combat the negative effects that fast or processed foods have on your body. You may also become more sensitive to allergens. If you are immune-compromised, eating fast food may make you sick because it has high levels of sugar that can feed bacteria, yeast and fungi.

12. Fast Food Affects Your Bones

A study published in the Archives of Pediatrics & Adolescent Medicine found that girls who eat lots of fast food have a greater chance of becoming obese and developing osteoporosis later in life. The study used data from the long-term Project Viva, which included more than 2,000 pregnant women who answered questions about their eating habits when they first enrolled in the study between 2009 and 2012.

13. Fast Food Affects Your Ability to Fight Cancer

According to Dr Joseph Mercola, fast food contains many cancer-causing chemicals such as heterocyclic amines (HCAs). And polyaromatic hydrocarbons (PAHs). Studies show that HCAs can trigger the uncontrolled cell growth of cancerous tumours. PAHs also stimulate tumour growth and may hinder apoptosis, which is the self-destruct sequence that cancerous cells should follow.

14. Fast Food Affects Your Ability to Digest Foods

The high level of refined carbohydrates and added sugars found in fast food can cause gastrointestinal problems such as bloating, gas, heartburn and diarrhoea. Eating a diet high in fat can also damage your healthy gut bacteria and lead to a leaky gut, which is a condition that can cause toxins to leave your digestive system and enter your bloodstream, causing damage throughout your body.

15. Fast Food Makes You Fat

Eating fast food frequently can add inches to your waistline. The average burger has over 500 calories and 40 grams of fat! Fast food is usually high in calories, fat, sugar and salt. Consuming large amounts of these nutrients can lead to weight gain when you eat more than you burn off through physical activity.

16. Fast Food Causes Diabetes

The high levels of sugar and refined carbohydrates found in most fast food items can lead to type 2 diabetes, which occurs. When your body becomes resistant to insulin or doesn’t produce enough insulin to maintain an average blood glucose level. When you have diabetes, you have a higher risk of heart attack, stroke and other diseases.

17. Fast Food Affects Your Ability to Grow

Studies have shown that children who eat fast food frequently are more likely to be obese than children who don’t eat many of these items. This can prevent them from growing taller since obesity affects the amount of growth hormone your body produces. It also makes you feel tired and miserable, which can prevent you from exercising and playing sports.

The Bottom Line

If you’re feeling sick after eating at a fast food restaurant, it may not just be the greasy fries that are making you feel queasy. Some people experience nausea and light-headedness when they eat foods high in fat. For others, these issues can stem from anxiety or stress-related problems like insomnia, heartburn, ulcers, gallbladder disease or even anaemia.

While this is more of an individual problem than something, most would associate with visiting your local McDonald’s for lunch on the way back to work. If you’re experiencing any of these symptoms following fast food consumption then speak with your doctor about what might be causing them before continuing down this unhealthy path. It might help!
