This guide provides clear instructions for adopting a healthy eating pattern and reducing the consumption of foods high in saturated and trans fats, salt, and sugar, especially fast food. Moreover, it advocates replacing these unhealthy choices with nutrient-rich foods to prevent the health conditions mentioned below.
Obesity is the first health concern that comes to mind when discussing the negative impact of fast food. Fast foods are typically high in unhealthy fats and carbohydrates, leading to a high-calorie intake and weight gain. These foods are often prepared in ways detrimental to one's health and are frequently served with fries, soft drinks, and various sauces, all of which contribute to high-calorie meals.
Fast food contains high levels of salt, which includes sodium, a preservative that prevents spoilage and enhances flavour. Regular fast food consumption introduces a large amount of salt into the body, which can lead to high blood pressure.
High blood pressure is a serious health issue. Over time, it can negatively affect the body's vascular system, causing hardening or narrowing of blood vessels and increasing the risk of heart attacks and heart disease. Therefore, it is advised to eliminate or reduce fast food consumption from one’s diet.
After eating fast food, some individuals may experience bloating, stomach discomfort, or difficulty going to the bathroom. This happens because fast food typically lacks fibre, which is crucial for preventing constipation.
Fast food contains processed carbohydrates that have lost much of their fibre and essential nutrients, causing them to convert into sugar quickly. Additionally, fast food often has high sugar content, leading to rapid spikes in blood sugar levels. This prompts the pancreas to produce more insulin to lower these levels.
Over time, these frequent blood sugar spikes can make the body less responsive to insulin, prompting the pancreas to produce more. Eventually, this leads to the deterioration of insulin-producing cells, leading to type 2 diabetes.
Fast food’s negative effects extend beyond physical health to cognitive functions. Consuming large amounts of sugars and fats has been shown to adversely affect the parts of the brain responsible for memory and concentration. A 2020 study on a group of university students published in the medical science journal "Sadra Medical Journal" found that students who consumed significant quantities of fast food experienced a noticeable decline in their short-term memory strength. Therefore, it is important to reconsider fast food consumption to maintain cognitive health.
Maintaining health is a priority for all, and reducing fast food consumption is necessary to avoid its detrimental effects and achieve this goal. It is also essential to adopt a healthy diet consisting of home-prepared meals rich in vitamins and minerals, including vegetables, fruits, whole grains like oats and quinoa, and protein-rich foods such as chicken and meat.
While some may argue that fast food can provide the body's nutritional needs and induce a feeling of fullness, the aforementioned nutritious foods are more effective in fulfilling these goals. Additionally, drinking water and calorie-free beverages, such as green tea, while minimising sugar intake as much as possible, can contribute to maintaining good health when combined with a nutritious diet.
