Apples are asking what I think about bread. The short answer: not very much. But this is an ongoing issue worthy of some debate, so let’s get it started:
In general, the best source of carbohydrates is a vegetable, not a grain (unless you are an athlete, in which case, you’re probably just trying to consume as many calories as possible).
Among other things, grains contain lectins , a mild toxin (is there such a thing as a mild toxin?). Technically, grains don’t “want” to be your next meal. They didn’t really evolve to be our food source – we humans exploited them when we figured out how easy they were to grow. Consequently, they’re in everything – especially processed foods – because they’re cheap and can be made into just about anything, from sauces to syrups to candies to side dishes.
It’s not for nothing that our ancestors ate  only flesh (meat and fish), nuts, roots, fruits and berries, and grabbed at wild greens for fiber. In fact, there’s a whole dietary movement – sometimes called the Caveman diet, sometimes the Paleo diet – we cautiously subscribe to (I’m uncomfortable with extreme diets, though I also am uncomfortable with how we define “extreme”!) Why? Grains are a relatively new thing for humans, and the evidence increasingly points to the notion that this isn’t a good development. If you’re into learning more, check out our Carbs  category.
I recommend that you stick to zero grains a day. On the whole, I stick to vegetables for my carbs – I just don’t really “do” carbs. Vegetables have far more vitamins, fiber and minerals than grain-sourced carbohydrates, and they are much lower in calories, giving you room for protein and vital fat. Vegetables also keep your blood sugar levels at a healthy, low level, so you don’t start pumping your pancreas to death.
Scientists point out  that the human body was designed to subsist on a mixture of fresh vegetables, good fats (from nuts, fish, oils, and meats), and protein (from fresh meats, beans, a little dairy, and fish). Add in plenty of water, occasional fruit, and you’re set. On the whole, avoid the processed, unnatural, refined, sugary stuff. Try it for just one week  and you’ll notice a big difference – really.
