This is an article that provides good explanation about how healthy foods can change into “devil” foods. See what is in cod? A 120-gram-grilled cod has 115 calories and 1.4g of fat. It’s a good source of protein and contains potassium, iodine, zinc, and B vitamins. Consider what potatoes have to offer? They are important source of vitamin C, low in fat, have fiber in the skins, potassium, phosphorus, and B vitamins. Read these changes carefully, as written in the article, once they are fried. The same cod now has 450 calories and 28g of fat, and those potatoes now contains 240 calories and 12g of fat! What the frying process has done to them, now you easily gain weight and bad health. Well, I really suggest you read this article for further understanding. Check here.
