I think there are many reasons why the formula has not been improved. First of all, no new cooking materials have been found in the world. If we find a brand-new ingredient that can replace the oil and sugar in the baking process through continuous exploration, then this problem will be solved very well, but there is no such ingredient, so we are also improving the formula and production method step by step.
When making baked goods, we really need to use a lot of oil and sugar. If you use the oven at this time, you don't need to put too much oil. Too much oil will also affect our health and taste. Secondly, baked goods contain too much sugar. If eating ordinary sugar will raise blood sugar, we can replace the white sugar, soft candy or brown sugar we use with low-calorie sugar or xylitol that dieters can eat. This will not only affect the taste, but also make our bodies healthier. If we eat too much real sugar, it will make us fat and affect our health.
If we buy baked goods made on the same day in the bakery, it is relatively healthy, because preservatives and preservatives will not be added, but if we often buy puffed food and fried food online, the substantial damage of these foods will be much higher than that of baked goods we buy in snack bars. Therefore, if you want to keep healthy, you can buy some baked goods in dim sum shops, and don't buy bagged or canned puffed food online, otherwise you will eat not only cheap sugar, but also cheap preservatives and food additives. These things will do more harm to our health.
