Many people have the misconception that foods with similar names belong to the same category and can be used interchangeably, but this is not entirely the case. The following foods are particularly noteworthy.
Carrots are not part of the radish genus.
White radishes, green radishes, and water radishes belong to the large radish family, which is part of the Brassicaceae (cabbage) family. They aid digestion and stimulate appetite. Vegetables from the Brassicaceae family also contain glucosinolates, which have anti-cancer properties. Although carrots may look similar to radishes, they are actually from the Apiaceae family. In addition to being rich in various vitamins and minerals, carrots are rich in beta-carotene, which is responsible for their consistent orange color. This nutrient can be converted into vitamin A in the human body, helping to relieve eye strain, moisturize the skin, and boost immunity.
Soybeans are not a grain.
Foods with the character "bean" (豆) are not all whole grains. Soybeans, green beans, and black beans belong to the soybean family. Unlike starchy legumes such as red beans, mung beans, and kidney beans, soybeans have a lower starch content but significantly higher levels of protein and fat. Because they are rich in protein, soybeans can be used as a meat substitute and are often called "meat that grows in the fields." Various soy products made from soybeans, such as soft tofu, dried tofu, and tofu skin, are excellent sources of protein, but they cannot replace grains.
Japanese tofu is not tofu.
Whether in a restaurant or a supermarket, the delicate and tender texture of Japanese tofu is loved by many. In reality, Japanese tofu is primarily made from eggs and has no relation to traditional northern or southern tofu. You cannot obtain the nutritional components of tofu from it. Southern and northern tofu are rich in high-quality protein and calcium, two nutrients that are found in very small amounts in Japanese tofu. Although Japanese tofu has a tender texture, its high water content dilutes its nutritional value.
Ketchup is not tomato sauce.
Pure tomato sauce is a paste made by blending tomato pulp and contains only one ingredient: tomatoes. It is rich in lycopene, dietary fiber, and minerals. The sweet and sour sauce served with french fries in fast-food restaurants is ketchup. Its ingredients are numerous, including not only tomatoes but also added salt, sugar, flavor enhancers, thickeners, and spices. Its nutritional value is much lower than that of tomato sauce.
