LOL.

I laugh because my wife and I said the same thing about some people a couple years ago that ate huge amounts of meat where we over winter in Bonaire. Man were we wrong.

Turns out that is another medical myth that endures. I would have a hard time finding the video that covers that, but there is actual research on the subject. Turns out the only ones that need be concerned with that are people that already have compromises kidneys (someone that has had one removed or has severe reduced function for other reasons). People with normal kidney function have nothing to worry about.

The "too much meat causes kidney failure" follows right along the myth lines that salt is bad for us. Salt is good for us and only a very small portion of the population is salt sensitive and can have problems with consuming too much salt. It is a lot more likely that many people consume too little salt rather than too much.

If you go on a low carb or keto diet, you likely will need to up your salt. At least temporarily, till your body becomes adapted to the new diet. Carbs retain more water and when you cut out the carbs the water flushes out along with a lot of salt, as well as potassium and magnesium, but mostly salt. If you go low carb and get a headache or just feel tired, take a teaspoon of salt. It is likely low salt. You will pee out any you don't need.

I remember in high school in track (1968) we used to have a gallon jar of salt pills at the gear checkout counter that were available to anyone who wanted to take them. Knew more then than we do now. :-)
