1. Instant Noodles
Instant noodles are a staple food for many people. However, they are packed with saturated fats, refined carbohydrates, and lack fiber, which can increase bad cholesterol levels in the blood and raise the risk of heart disease.
A typical 85-gram serving of instant noodles contains 14.5 grams of fat, of which 6.5 grams are harmful saturated fats. Students, in particular, should consider limiting their intake of instant noodles.


2. Popcorn
Popcorn is high in salt, which can raise the sodium intake in your diet. According to Mayo Clinic, for those sensitive to sodium, added salt can cause water retention and elevated blood pressure, leading to kidney disease, stroke, and heart disease.
In a 2009 study on movie theater popcorn, the Center for Science in the Public Interest found that some large servings contained 1,500 mg of sodium, equivalent to the recommended daily sodium intake for an adult. If you're going to the movies with your partner, it's a good idea to skip the popcorn.


3. Canned and Packaged Foods
If you think canned food is safe and hygienic, think again. Most canned goods contain BPA-A in their packaging. According to breastcancerfund.org, even small amounts of exposure to BPA-A can increase the risk of breast cancer, prostate cancer, and other disorders.
It's always best to buy fresh ingredients for cooking. Use canned foods only when necessary and consume them in moderation.


4. Alcohol and Beer
Alcohol and beer are alcoholic beverages that are directly absorbed into the bloodstream, bypassing the digestive process like other foods.
This means that the more alcohol and beer you consume, the harder your liver has to work to filter them out, which can harm the liver. Excessive drinking also increases the risk of traffic accidents, domestic violence, and other issues. If you tend to drink a lot, consider cutting back for your health.


5. White Bread
White bread is typically made from wheat, which contains gluten protein. For this reason, most breads are not suitable for people with celiac disease or gluten sensitivity. Even for those who can tolerate gluten, most commercially available bread is not healthy. This is because most bread is made from refined flour, which has little nutritional value (empty calories) and causes a rapid rise in blood sugar levels.
For those who can consume gluten, Ezekiel bread is an excellent alternative. Whole grain bread is also a better (or at least less harmful) option compared to white bread.


6. Industrial Vegetable Oils
Over the past 100 years, human consumption of fats has significantly increased. This can be largely attributed to the rise in consumption of refined vegetable oils such as soybean, corn, cottonseed, and canola oils. These oils are high in omega-6 fatty acids, which humans have never consumed in such large quantities before.
There are serious concerns about these oils. They are highly sensitive to oxidation and can cause an imbalance in the body's oxidative state. They have also been linked to an increased risk of cancer. Therefore, it's better to opt for healthier fats like coconut oil, butter, extra virgin olive oil, or avocado oil.


7. Margarine
Margarine was once marketed as a healthier alternative to butter. Thankfully, most people now recognize that this is far from accurate. Margarine is a processed food designed to resemble butter in both appearance and flavor. It contains many artificial ingredients and is typically made from industrial vegetable oils that are hydrogenated to thicken them. This process significantly raises the fat content.
It’s important to note that manufacturers can label their products as 'trans fat-free' if they contain less than 0.5 grams of fat per serving, but this still amounts to a significant quantity of fat. It’s better to opt for real butter, especially from grass-fed cows.


8. Cookies and Pastries
Most cookies and pastries, especially those made with refined flour, are not healthy choices. They are typically made with refined sugars, processed flour, and unhealthy fats, such as shortening (which contains trans fats).
While these treats may be delicious, they are some of the worst things you can put into your body. They provide little to no essential nutrients, but they are packed with empty calories and harmful ingredients.


9. Processed Cheese
Cheese is a nutritious food. It is rich in essential nutrients, with a single slice providing the equivalent of a cup of milk. However, processed cheese is quite different from regular cheese. It is typically made with various additives and is manufactured to mimic the appearance and texture of real cheese.
While real cheese can be beneficial, processed cheese is not. Always check the label to ensure the cheese you're consuming is actually real cheese.


10. High-Calorie Coffee Variants
Coffee has evolved into many different beverages today. While it's generally good for health and packed with antioxidants, studies suggest that coffee drinkers have a lower risk of serious conditions like type 2 diabetes and Parkinson's disease.
Unfortunately, the things we add to our coffee can turn this healthful drink into something detrimental. If your 'coffee' is loaded with cream and artificial sugars, it becomes unhealthy. These additions provide empty calories and are just as bad as sugary drinks. Therefore, it's best to stick to regular black coffee. However, adding a small amount of full-fat cream or whole milk is fine.


11. Processed Meats
Processed meats, such as deli meats, bacon, and sausages, often contain chemical preservatives that keep them fresh and appealing, but they are also cancer-causing agents. High levels of nitrites and nitrates in these meats have been linked to an increased risk of colon cancer and other forms of the disease. Additionally, consuming large amounts of processed meats raises the risk of stroke, especially in older adults.


12. Carbonated Soft Drinks
Carbonated soft drinks have been scientifically proven to be one of the contributors to cancer. Packed with excessive sugar, food chemicals, and artificial coloring agents, soft drinks can "acidify the body" and potentially speed up aging and cancer development.
Certain chemicals commonly found in these drinks, like caramel color and its derivative 4-methylimidazole (4-MI), are also linked to cancer. Regular consumption of soft drinks increases the risk of diabetes, and people with diabetes should avoid them. If you're a frequent consumer, consider reducing your intake.


13. Fried and Deep-Fried Foods
Fried and deep-fried foods are a popular choice for many, especially during colder weather. These foods are typically high in energy, visually appealing, and incredibly flavorful. However, experts caution that they should be consumed in moderation.
Consuming them excessively can increase the risk of cancer and other severe health issues. Since these foods are cooked in oil, they are high in cholesterol, which can lead to arterial plaque buildup and increase the risk of heart disease.
