Over the years I trained myself to read the ingredients labels on every product I buy that is packaged. Note, processed food is constantly enhanced so don't be surprised that the ingredient list changed. You also may want to know that the ingredient list is listed from the ingredient that is used the most and then to the least.
The best nutrition for your body is to consume whole foods - or the least amount of ingredients. The more natural foods you eat the better you will be. Processed foods contain preservatives, chemicals, fillers, artificial flavors and artificial colors.
I avoid any processed food that is contains artificial flavors or artificial colors, but the most I avoid is the High Fructose Corn Syrup often abbreviated HFCS. Corn syrup is just a cheaper version of cane or beet sugar.
Why add to baked foods? HFCS preserves freshness in the baked foods. It is definitely a natural sweetener in other foods.
Why avoid it? Studies revealed that fructose turns into fat, thus the obesity. Your liver does not process or metabolizes the corn syrup effectively. It also increases risk of coronary heart disease, stroke and cancer, and type-2 diabetes.
I think there is enough reasons for not to consume anything that contains High Fructose Corn Syrup.
