It's easy to get stuck in a rut and choose the same old apple or broccoli instead of venturing outside your comfort choices. Make it a goal to try at least one new fruit or veggie a month. Try to buy what's in season locally and shop at farmer's markets if you can - you'll not only get fresher produce, but you'll usually pay less for it. Try to buy organic to spare yourself from ingesting toxic pesticides and chemicals, but whatever produce you buy, do wash it before eating it. I know you've heard this a million times, but your body needs water to function properly.
Dehydration is one of the biggest causes of fatigue.
Your skin will look better, your breath will smell better and you will most definitely feel better. Caffeinated beverages can dehydrate you, so sip some water along with your coffee or tea. Fruits and veggies are a great source of water and count towards your daily requirement. Your urine should not be dark colored - if it is, it's a sure sign you need more water. Add a slice of lemon, lime or orange for color and flavor if you like, but be sure to drink lots.
