Bare with me, here.
My children used to get strep ALL THE TIME. They would get it, pass it around, any by the time the last one got it, the first one got it AGAIN and it started all over. I am not kidding. I was at my wits end! Then, when they were finally "cured", 6-12 months later, they'd start the whole shebang again. UGH.
I was talking to an elderly woman during an outbreak of strep at my house, and she laughed and said, "You don't need doctors to cure strep. All you need is apple cider vinegar!". So I asked her about that, and she said that where she came from (somewhere in the South, don't remember where exactly??), everyone used Apple Cider Vinegar to cure strep. I thought she was crazy, but I was willing to try anything at that point (including and not limited to voodoo lol Just kidding!!), so I did it. Now, my kids haven't had strep in just over 7 years.
What you do is take a glass of water (8-12 ounces) and add between 10-20 drops of apple cider vinegar to it. SIP at the water (don't chug!), and it WILL heal you. What happens is the cider vinegar changes the PH of your throat, and the strep can't live there anymore! HA!
It really, really does work. Please try it (I know I'm not a doctor and I can't prescribe, but it REALLY works). Everyone I know thinks I'm nuts when I suggest it, but when they try it, it works.
Then, any time you feel like you're starting to get a sore throat from here on out, do the cider vinegar in water. If it's just a normal sore throat, it's not going to do much, but if it's strep, you won't get it again!
That said, on the "what to eat" front:
Yogurt thinned with some milk (good bacteria will help your body fight the infection)
Fruit and yogurt smoothies (you need fruits and vegetables to boost your immune. Try these two smoothies:
1 banana
2 large kale leaves
1 cup frozen strawberries
1 carrot
1 apple, cored
2 TBS toasted wheat germ
Half a cup water
Blend until smooth.
Or:
2 cups chocolate milk (I prefer soy, rice, hemp or almond for nutrition)
1 banana
Half a cup of greek yogurt
1 kale leaf
2 TBS toasted wheat germ
1 TBS sesame tahini
1 TBS peanut butter
1 TBS ground flax seed
Warm (NOT hot) chicken broth, add some miso for extra nutrition! Add some VERY SOFT cooked noodles for some substance. Add a little bit of vinegar for extra health benefits. :)
Mashed avocados with cocoa powder, agave or maple syrup and a little salt. Thin it down with a chocolate milk of any variety (dairy, hemp, soy, etc). It's kind of like a pudding and is VERY nutritious. Because of the good fats in avocado, it also will give you some "substance".
Ice cream, stirred until it's soft (there are studies now that show that dairy does NOT produce excess mucous, as previously thought)
