Don't blindly eat nutritious food, how can it be no nutrition?

Prepare our three meals a day in full accordance with the requirements of the nutritional recipes, but it seems to be of little help to our health. Is it because the experts have problems with the recipes, or have the nutrition been stolen? Cooking good food is good for human health, but if the food is processed, many nutrients will be destroyed if you don't pay attention to proper cooking.
