In the early 20th century, potato chips were promoted as a healthy snack because they were made from whole potatoes. Health experts suggested that they provided a good source of energy and were easy to digest. Now, we know that chips are loaded with unhealthy fats and sodium.

White bread, made from refined flour, was once considered healthy for its rich texture and fortification with vitamins and minerals. It was promoted as a high-energy food that provided strength and stamina. Today, it’s recognized for its high glycemic index and lack of fiber, making it less ideal for health.
4. Canned Fruit

Canned fruit was once hailed as a convenient, healthy option, especially during the winter months when fresh fruit wasn’t available. It was packed in syrup and considered a good source of vitamins. However, with its high sugar content, canned fruit no longer holds the same “health” status.
5. Margarine

Margarine was introduced as a healthier alternative to butter due to its lower saturated fat content. In the mid-20th century, it was seen as heart-healthy and a staple for those looking to lower cholesterol. Over time, we learned that many margarines contain trans fats, which are linked to heart disease.
6. Fruit Juice
