There is much debate nowadays as to what makes up a healthy diet. For example, scientists have insisted for years that a big enemy of health is fatty food. However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar. Heart disease is the number one killer of Americans. And in America, people who receive 25% of their daily calories or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (ournal of the American Medical Association, 2014). This is true regardless of how healthy the rest of their diet might be. Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.

Beyond this, you can keep healthy by consuming different categories of fresh foods, especially fruit and vegetables, which are full of vitamins and fibre, rather than processed foods. Processed foods often contain less nutrition, and have higher quantities of sugar, salt and fat than fresh ingredients. Besides this, it is also important to have some meat, beans, or dairy products in your diet, as they provide the necessary protein for strong bones and musclle growth. As with everything in life, moderation is key. The ideal diet is a balanced one, without too much or too little of any one thing.
