How many sodas a week is too many?? Is it better to eat before or after excercise and how long??

In a word, the answer is ONE is too many sodas per week.  Soda provides absolutely no benefit to the body and only tears it down.  First, the sugar in sodas supresses the immune system for up to 12 hours by as much as 50%.  Second, the phosphoric acid in sodas wreaks havoc on pH balance.  The pH level of the acid in soda is equivalent to battery acid.  This causes the body to leach calcium from bones in order to neutralize the acid.  To learn more about the benefits of maintaining a healthy pH balance, and to find healthy alternatives for sodas, please take my FREE Alkaline Food Test

Here is the answer to the other part of your question about eating and exercise.  In general, it is best to eat within 30 minutes after exercise.  However, it is also important to have plenty of fuel in your system when you do exercise.  It is best to eat low fat, healthy complex carbs with as few calories as possible before exercise.  In other words, avoid simple carbs like sugary breads, bars and cereals.  Instead, eat fruits and vegetables before exercise for long lasting energy, and be sure to get enough carbs, calories and protein afterward.  You don't need high protein snack bars like they sell at the health club.  Those have way too much protein for most people and include other chemical isolates that don't help the body in the long run. There are other healthy snacks you can choose that will provide healthier long, lasting energy for workouts.

I agree with Cliff.  The right amount of soda is ZERO... The calories from all regular sodas are empty and contribute to obesity.  THe phosphoric acid from COLAS leeches calcium from the bones (this has more to do with the phosphorus-calcium bone balance than acidity, and is a problem specific to COLA-type of sodas.) The body does not recognize "liquid calories" as food and the brain does not register satiety after drinking a soda, so you keep wanting MORE soda.  Water is the best source of hydration, either plain, or if you like it flavored, try lemon or lime (vitamin C), fresh or dried Rosella (red hibiscus: good for blood pressure), or teas (green, white, black: antioxidants), or Hierba Mate (antioxidant & appetite suppressor).  However, there is no benefit to any of the "vitamin water," especially if you have a healthy diet.

As for exercise, any time is better than no exercise.  Are you exercising to lose weight, stay in shape, or are you an athlete who wants performance?  There is usually no need for sports drinks, health bars, high protein shakes and the likes.  A complete breakfast (i.e. oatmeal, milk, fruit) or lunch (green salad, grilled fish, whole wheat bread) will suffice for a routine workout.  Better to eat 30 minutes before the workout, or to wait at least 30 minutes after ending the workout so that the blood flow redirects from your limb muscles to your digestive system.  If you want to exercise first thing in the morning, before breakfast, make sure to be hydrated (1 glass of water before you get going) and 1/2 cup of orange juice for quick glucose release.  Have a great workout!
