Certain things are almost guaranteed to taste good to us -- salt, sugar and fat are just a few examples of ingredients that most people enjoy and (sometimes) can't stop themselves from eating. Eating anything in excess can be bad for you (see the "truckload of vegetables" debating technique), but people seem to especially focus on salt, sugar and fat. Here are just a few links that provide some data points on the health effects of these three tasty food items.

- For decades, we've been told that our salt intake was probably too high, but a recent study -- spanning 50 years and over 45 countries -- concludes that dietary salt intake is normal at around 2,600 mg to 4,800 mg per day (versus the US recommendations of no more than 2,300 mg per day for a healthy person). This conclusion suggests that our salt intake is regulated by physiology and biological need, not by how much salt is in our food. [url]
- Various kinds of processed sugars seem to be an increasing part of the modern diet, and sugar intake correlates with obesity rates across many countries. Should we try to restrict sugar intake with taxes or allow more artificial sweeteners on the market? Or..? [url]
- It's a myth that eating fat will make you fat -- eating an excess of calories from any source (eg. carbohydrate, protein, alcohol) makes you fat. In fact, the percentage of calories from fat from our diets has actually gone down in the US over the last 30 years, but obesity rates are clearly much higher. [url]
