Processed Foods
Processed meats like bacon, ham, and sausages are convenient and tasty, making them a popular choice for breakfast. However, these foods contain high levels of nitrites, which give the meat its pink color, extend its shelf life, and make it softer.
When nitrites enter the body, they combine with protein-breaking compounds in the stomach, forming nitrosamines, which are linked to UT [unclear abbreviation] development. Therefore, it is best to minimize the consumption of processed meats in the morning meal.

Deep-fried Foods
Many people, especially children, enjoy deep-fried foods like French fries, fried chicken, and breaded meats for breakfast because they are tasty and convenient. However, these foods are extremely high in fat, and regular consumption can lead to weight gain, obesity, high cholesterol, and cardiovascular issues.
Additionally, the World Health Organization (WHO) classifies deep-fried foods as Group 2A carcinogens, indicating they are ‘probably carcinogenic to humans,’ alongside red meat.
Salted Fish
Salted, marinated, and dried fish are inexpensive and tasty, making them a common breakfast side dish with rice. However, regular consumption of these fish products can increase the risk of throat cancer. This is because salted fish often contains high levels of nitrites, which, when combined with stomach acids, form nitrosamines, known carcinogens.
Consuming Very Hot Foods
While some people prefer their food very hot, believing it to be healthier, this practice is misleading. The World Health Organization (WHO) warns that consuming extremely hot foods can increase the risk of cancer in the esophagus, mouth, and throat, as high temperatures can damage these organs.
Eating very hot foods can also harm the intestines. Therefore, regardless of preference or time constraints, food should be consumed at a safe temperature, ideally between 40° and 50° Celsius.

Rice with Pickled Vegetables for Breakfast
While eating rice for breakfast can be a filling and economical choice, pairing it with pickled vegetables is not advisable. Pickled vegetables like cucumbers and cabbage are not only high in salt but also produce significant levels of nitrites during the fermentation process. Additionally, the high salt content in these pickles can negatively affect kidney health. Thus, it is best to avoid including pickled vegetables in your morning meal.
