National Junk Food Day

National Junk Food Day is a celebration of indulgence in calorie-rich but nutritionally poor foods coined as “junk food” by Michael Jacobson, director of the Center for Science in the Public Interest. This term encompasses items low in protein, minerals, and vitamins but high in sugar, fat, and salt, including fried fast food, snacks, desserts, candy, chewing gum, and sugary beverages. While some items like pizza and hamburgers can straddle the line between junk and healthy food, their categorization depends on ingredients and preparation methods. The history of junk food traces back to the late 1800s when packaged foods first entered American life. Post-World War II, the industry boomed as people ate out more, creating a demand for high-preservative, prepackaged products. By the 1970s, junk food gained a bad reputation, with Jacobson seeking to curb the consumption of high-sugar, high-salt, and high-preservative foods. National Junk Food Day provides an opportunity to enjoy favorite indulgences without guilt, emphasizing moderation to avoid health concerns. Though not ideal for everyday consumption, this day allows individuals to satisfy cravings and enjoy high-calorie treats. Over the years, popular junk foods have evolved, from candy in the 1800s to the dominance of pizza in the present day.
