Q:Is eating three sandwiches a day a bad idea when youre on a diet?
That all depends! It can be bad in the long run if you aren't getting balanced nutrients from the sandwiches. With just ham and cheese, there's no way you could be getting everything your body needs nutritionally! Try adding variety into your sandwiches using lettuce, tomatoes, different meats, different dressings, new veggies, etc. Of course, this doesn't mean to go overboard with any one ingredient - keep it healthy. And remember, don't always use fat free dressings; a lot of the time, when there are other veggies involved, they are best consumed with a healthy fat source for best absorption. Regarding the bread... whole wheat bread isn't always what it seems. Real whole wheat bread is made from real whole grains, and you must check the ingredient panel to ensure this is what you are eating; there has been a bit of trickery in the bread industry. The first ingredients should contain items such as whole wheat flour, 100% rolled oats, whole grain corn, etc. Any enriched flour, even if whole wheat, is not what you're after. Sandwiches can be great as long as they are balanced nutrition-wise, so if you really like 'em, I wouldn't say they are a problem. Just make sure your caloric intake is correct for your daily needs, and that you're getting some variety.
