I will tell you about the 8 worst foods that you should never buy at the supermarket. Everyone easily goes to the supermarket and buys the food they need. However, if you buy it recklessly and eat it, you may end up harming your health. Today, I will tell you about the 8 worst foods that even doctors say you should never buy at the supermarket.

The worst food at the supermarket

I think it is very important to know exactly what foods you should be careful to eat for the health of your family. We will look at 8 foods that are harmful to our health, even though we eat and drink them all the time.

1. Bottled water

Water is the most important substance that enters our body. If it is sealed in a water bottle, it seems like it can be eaten safely anywhere, anytime, but did you know that carcinogens have been found in sealed bottled water?
 
Bottled water is easy to spoil if left in the sun for a long time, as the plastic material of the PET bottle melts into the water, changing its color, taste, or causing an odor. If you drink outdoor bottled water exposed to high temperatures and strong ultraviolet rays, it may contain carcinogens such as formaldehyde and acetaldehyde. 

2. Canola oil, grape seed oil

Cooking oil is indispensable for cooking. There are many different types of cooking oil. Among them, canola oil and grape seed oil are the most controversial products due to their side effects.
 
Grape seed oil and canola oil have been found to have a significantly higher increase in trans fat content due to heat than other cooking oils. Oil becomes rancid even if it is exposed to air for a long time or if it is cooked at a high temperature or high humidity.
 
When rancidity begins, the good components in the oil are destroyed, and it is converted into harmful substances such as trans fat and carcinogens such as formaldehyde, which can lead to myocardial infarction, angina, stroke, atherosclerosis, coronary artery, heart disease, cancer, diabetes, and allergic symptoms. The oxidative stability of both canola oil and grape seed oil is also not good. In addition, canola oil is a GMO (genetically modified food).
 
Contrary to the announcement that GMO foods are safe to eat, there have been studies showing that when GMO potatoes were fed to laboratory mice for 100 days, more tumors developed and serious problems occurred in the liver, kidneys, and pituitary gland, leading to endocrine disruption and damage such as impaired immune system, kidney allergy, etc.

3. Fresh fruit juice

It has been revealed that fruit juice that we usually drink for our health is actually harmful to our health.
 
This is because the fructose in juice increases insulin resistance and stimulates hormones that cause abdominal obesity. If insulin resistance is high, too much insulin is produced, leading to diseases such as hypertension, hyperlipidemia, heart disease, and diabetes. Therefore, it is better to eat the whole fruit itself rather than fruit juice.

4. Cheese

Cheese goes well with various foods such as back ribs, octopus, tteokbokki, pork cutlet, pizza, and hamburgers. Did you know that the cheese that we thought was natural cheese without any suspicion is actually a lump of fat?
 
We generally know that cheese is made from milk fat. However, while the ingredients of natural cheese are fresh milk, there are cheeses that do not contain a single drop of milk, which are called imitation cheeses.
 
Imitation cheese is made by mixing vegetable fats such as palm oil and food additives such as rennet casein emulsifier, and its appearance, taste, and aroma are similar to natural cheese. When cooked warm, it is no different from regular cheese and it is difficult to distinguish it when mixed with other seasonings.
 
If you check the ingredient analysis of this cheese, if it says food additives such as rennet casein and palm oil, then you can see that it is using imitation cheese.
 
Excessive intake can lead to cardiovascular diseases such as hypertension and hyperlipidemia, so you should be careful when choosing products. It seems that you should check for natural cheese 90% or more on the ingredients list and purchase it.

5. Flour

Flour is a high-carbohydrate food composed of an average of 70 to 80% carbohydrates and 7 to 13% protein. It has a high glycemic index. It is quickly absorbed into the body and quickly turns into energy, but the remaining energy is all stored as fat, so if you eat more flour, you are likely to gain weight and the risk of developing fatty liver also increases.
 
Eating foods made horizontally can lead to excessive secretion of insulin, which can trigger diabetes, so people with diabetes or obesity-related underlying diseases should limit their flour intake. In addition, gluten contained in flour contains a protein called gliadin, which loosens the intestinal mucosa.
 
 Other side effects include decreased concentration, fatigue, thyroid problems, and weakened immunity, and studies show that they last for about 6 months. However, since you can't avoid flour altogether, it's a good idea to reduce your intake by half.

6. Processed meat

In 2015, the World Health Organization (WHO) classified processed meat as a Group 1 carcinogen, the same as cigarette smoke. The International Agency for Research on Cancer, based on a comprehensive study of the relationship between processed meat consumption and cancer development, concluded that processed meat could worsen the risk of developing colorectal cancer, and designated it as a Group 1 carcinogen.
 
Processed meat contains color fat and sodium nitrite for preservation. These ingredients, when combined with the amine component in protein, produce nitrosamine, a powerful carcinogen. Therefore, eating processed meat alone does not statistically increase the risk of developing colorectal cancer, but the risk increases depending on the amount of meat consumed.
 
It is said that eating 50g of processed meat every day increases the risk of developing colorectal cancer and rectal cancer by 18%, so while ham, sausage, and processed meat are called Group 1 carcinogens, it does not mean that you should never eat them. The important thing is the amount and frequency of intake.
 
In the first place, even if you don't consider the risk of developing cancer, excessive consumption of processed meat can lead to cardiovascular diseases and obesity, so it is advisable to avoid frequent consumption.

7. Hovenia dulcis tea

Hovenia dulcis tea has an alcohol-decomposing effect, so it is very effective in relieving hangovers when taken before or after drinking. Hovenia dulcis contains amperoside and hovenitin, which are very effective in preventing liver damage caused by alcohol. It boasts excellent effects on rheumatoid arthritis, muscle pain, constipation, digestive function, fatigue relief, jaundice, etc., but there are precautions and side effects to be aware of even with this hovenia dulcis.
 
People with liver disease or high liver enzymes should avoid hovenia dulcis tea. Many people take hovenia dulcis juice for their health, but this can also be a burden on people with poor livers, so caution is required. Also, most teas contain caffeine, and while the amount is less than coffee, it can exceed the recommended intake if you drink it as often as water.

8. Alcohol

Alcohol is a general term for ethanol made into a beverage. It is one of the narcotics designated by the World Health Organization. Some people drink it for the taste of the alcohol itself, some people drink it to cheer themselves up, and some people drink it for the atmosphere of the drinking party itself.
 
Alcohol, like cigarettes, is a Group 1 carcinogen designated by the International Agency for Research on Cancer. Cancers caused by alcohol include oral cancer, pharyngeal cancer, laryngeal cancer, liver cancer, colorectal cancer, breast cancer, pancreatic cancer, lung cancer, and many more.
 
Acetaldehyde, an alcohol metabolite, is a toxic substance that induces cancer cell formation. Alcohol also increases the risk of cancer recurrence. In the case of gastric cancer patients, reducing the amount and frequency of alcohol consumption can significantly reduce the risk of cardiovascular disease.
 
It is true that due to the saying that a moderate amount of alcohol is good for the body, we have been lenient about alcohol to some extent, but recently, the expert group does not recognize moderate alcohol consumption.
 
In 2017, the American Society of Clinical Oncology found that even one or two drinks a day could increase the risk of cancer. The recently revised Korean Cancer Prevention Guidelines recommend avoiding alcohol, even in small amounts. If you can avoid it for your health, avoid it and if you must drink, I hope you will drink it in moderation so that it does not burden your health.
