Some things you said are true (diet soda, energy bars, WHITE crackers, etc) . But some things youre saying are really getting my goat.
Baked potatoes ARE good for you. They contain potassium, vitamin C, Folic Acid, Magnesium, Zinc & Copper, with the skins containing a very large amount of fiber! Also, potato is only high - GI eaten plain, eating it with something like low fat cottage cheese, or even a drizzle of olive oil reduces the GI. If you let it cool down, potatoes are also a great source of resistant starch (i.e. like fiber, part of it doesn't actually get absorbed by the body). Potatoes are super-nutritious, as long as you don't mutilate them by turning them into french fries. Sweet & blue potatoes also contain various antioxidants which give them their colour.
Rice is very good for you; it has niacin, B vitamins, and other nutrients, just do the research you were supposed to do before misleading people with this post of yours. True, white rice has less fiber, but for some people who have delicate digestion and can't handle much fiber, white rice is actually a better alternative; it does have less nutrients, but theyre still there.
As for crackers, white crackers are no good. But wholegrain crackers are a great alternative if you must have crackers. Fruit is the best snack, but for those who can't limit their snacks to fruit, wholegrain crackers are great.
As for pasturisation - do NOT drink unpasturised milk! Is the high risk of contracting gastroenteritis really worth it? The reason that outbreaks are relatively rare is because we try to keep everything as germ free as possible! Goodness! As for juice, its safer to drink unpasturised, but then again youd be better off just eating the fruit. On that you are right.
But in general, you need to do research before posting stuff like this.
