Are you dehydrated? Sweating too much? What can replenish the electrolytes and other essentials that are lost?

I am searching for all and any info about what kinds of food or drink that will help replenish the loss of electrolytes in your body due to sweating to much or being/becoming dehydrated. It's downright hot this summer and I have been taking these OTC (over the counter) packets rehydration salts and mixing with water daily.
The composition is:
1.75g of Sodium Chloride.
0.75g of Potassium Chloride.
1.45g of Sodium Citrate.
10g of Anhydrous Glucose.
I don't drink gatorade or poerade because of the sucrose and dyes, so I am looking for natural ways to replenish my body with the essentials due to over sweating. Serious replies only please.

I live in Tucson, Arizona and the temp is in the triple digits this year. I use a great product by the company "Alacer" called "Electro mix" . It has no sugar and is extremely effective. I am putting a link for it below.
I am also including a link that shows food that hydrate. Stay cool. . .
