If I ask you what constitutes 'bad' eating, the kind that leads to obesity and a variety of connected diseases, youre likely to answer, 'Salt, fat and sugar.' Yet thats not a(n) 【C1】______answer. We dont know everything about the dietary【C2】______to chronic disease, but the best-qualified people argue that real food is more likely to promote health and less likely to cause disease than hyper-processed food. And we can further【C3】______that message: Minimally processed food—Real Food— should【C4】______our diets. Real food solves the salt / fat / sugar problem. Yes, excess salt may cause high blood pressure, and【C5】______sodium intake in people with high blood pressure helps.【C6】______salt is only one of several risk factors in developing high blood pressure, and those who eat a diverse diet and few processed foods need not【C7】______about salt intake. 'Fat' is a complicated topic. Most naturally occurring fats are probably essential, but too much of some fats seems【C8】______. Eat real food【C9】______your fat intake will probably be fine. 'Sugar' has come to【C10】______the entire group of processed, nutritionally worthless caloric sweeteners. All appear to be damaging because theyre added sugars, as【C11】______to naturally occurring ones.【C12】______: Sugar is not the only enemy. The enemy is hyper-processed food,【C13】______sugar. We know that eating real food is a general solution, but a large part of our dietary problems might【C14】______from the consumption of caloric sweeteners and / or hyper-processed carbs. For example, how to limit the intake of sugar? A soda tax is a(n) 【C15】______, proper labeling would be helpful, and—quite possibly most important,【C16】______its going to take us a generation or two to get out of this mess—restrictions【C17】______marketing sweet 'food' to children. Theres no reason to【C18】______action on those kinds of moves. But lets get the science straight so that firm,【C19】______, sound recommendations can be made【C20】______the best possible evidence. And meanwhile, lets also get the simple message straight: Its 'Eat Real Food.' 【C1】
