Fast Food Ingredients May Harm You
When it comes to fast food ingredients, many people would probably blurt out: beef, lettuce, bread, and potatoes. But did you know? The ingredients you consume go far beyond these few. Statistics show that while a McDonald's Big Mac appears to have only 7 ingredients, it actually contains 67 in total. Recently, the U.S. website "HowStuffWorks" published an article in which American nutrition expert William Harris, based on an investigation of five major fast-food chains like McDonald's and KFC, as well as a comparative analysis of the U.S. Food and Drug Administration's (FDA) list of common food ingredients and colorings, listed the most common ingredients in fast food and pointed out that some may cause health problems.
1. High-Fructose Corn Syrup: The most common sweetener. High-Fructose Corn Syrup (HFCS) is widely favored by the fast-food industry for its low price and preservative properties, often found in baked goods and beverages. However, doubts about HFCS have never ceased over the years. Reports indicate that many processed foods with added HFCS are high in calories but low in nutrition, and excessive consumption may lead to cardiovascular diseases and diabetes.
2. Salt: The most common seasoning. Salt makes food more palatable and is often found in bread, ham, and bacon, and is even indispensable in desserts like milkshakes and sundaes. The investigation found that a McDonald's Double Cheeseburger contains as much as 1.15 grams of sodium. Authoritative agencies recommend that adults consume no more than 6 grams of salt per day, 5 grams for children aged 7-10, and 3 grams for children aged 4-6. However, the investigation found that a meal at KFC contains an average of 5.2 grams of salt per person, increasing the risk of hypertension and cardiovascular disease.
3. Monosodium Glutamate (MSG): The most common flavor enhancer. The investigation found that almost all fast food uses MSG to enhance flavor. The safety of MSG has been questioned for many years. Although scientific research has confirmed that normal use of MSG is safe, experts warn that excessive intake of MSG can trigger asthma attacks, and consuming large amounts on an empty stomach can lead to short-term adverse reactions.
4. Soybean Oil: The most common oil or fat. Soybean oil is commonly used for frying in the fast-food industry and is also an important ingredient in margarine and desserts. Because soybean oil contains various unsaturated fatty acids and cannot be preserved for long, hydrogenation can reduce this drawback. However, hydrogenated oil produces trans fatty acids, which increase blood viscosity, accelerate arteriosclerosis, and raise the risk of cardiovascular disease. Many European and American countries have already banned hydrogenated oil, but in China, it is still widely used by the fast-food industry.
5. Citric Acid: The most common preservative. It is found in fruits like lemons and grapefruits and can increase the environmental acidity for microorganisms, making it difficult for bacteria to grow and reproduce. Although citric acid does not harm the human digestive organs, it promotes the excretion and deposition of calcium in the body, which may lead to hypocalcemia and increase the risk of duodenal cancer.
