Bad for kidneys.
...
I know you’re only looking for input from tcm experts, however, if I could throw my 2 cents in on the subject.
High protein diets are not damaging to the kidneys first off. You have to understand the function and what protein does. Protein is the building blocks of our body. High protein diets, thus improve the functions of the organs in the body as they have all the materials they need to function at their best. That being said, if you already have damaged kidneys, the protein can be a problem. But IN THIS CASE ONLY and that’s a whole other can of worms as to why.
For the protein shakes, if you want to build muscle it’s a good idea. All protein isn’t equal. The amino acid profile of different protein sources needs to be considered. This is the exact reason vegans can’t compete with athletes with animal products in their diets. One source is better than the other. You could cook up some eggs real fast sure. But you’d need too much to get the same protein. As far as what the processing does to the function of the proteins. That’s unclear. I’ve never seen anything in the scientific literature that shows protein powders aren’t absorbed all the way. In fact, we know for a fact that protein from meat definitely isn’t fully absorbed. From a powder I would imagine more is absorbed. And the proof is in the pudding as far as its effectiveness. Body builders from all backgrounds use it to amazing effect.
Bottom line with protein powder is simple. It’s meant as a supplement. It has a practical purpose. That’s it. Getting a high amount of protein in your diet without going over calories is hard. Protein powders make it easier. You can find powders that are just protein and that’s it. No additives. Also, for people wanting to maximize their gains in the gym, powders have their place. They digest and get into the bloodstream almost instantly and that can be powerful when trying to get the most out of your workouts.
For body recomposition, high protein diets are seen time and time again in the real world, despite any tcm theory on it, as the most effective way to gain or lose weight. Protein powders thus have their place as a way to get more protein and not too much calories. High protein diets ARE NOT DANGEROUS. Bottom line. Hope that helps.
Fixed your formatting. I was expecting your reply much earlier, knowing part of your background, and it's exactly as I expected.
All I can tell you is too look for studies that are conducted objectively. In order to accomplish that, try what one of my teachers called the "beervan" test (Terrible name, but effective strategy for remembering). You need to check for:
:arrow: Bias
:arrow: Expertise
:arrow: Experience
:arrow: Reputation
:arrow: Vested interest
:arrow: Ability to observe
:arrow: Neutrality
Studies shilling for high-protein diets having no negative impact (almost) always are sponsored (or conducted) by businesses that sell those powders you love so much. Almost every medical professional knows that high-protein and high-carbohydrate diets are unhealthy, just like diets high in saturated fats. Every medical professional also gets paid to refer drugs and supplements, and almost every one of them works to reinforce that relationship with the pharmaceutical industry (of which supplements are part), rather than to solve their patient's issues.
TCM is not theory. It's fact. Way ahead of conventional medicine, regardless of what you may decide to believe. The 3 main reasons to support my statement are:
:arrow: It's holistic, whereas conventional medicine is reductionist
:arrow: It focuses on causes, whereas conventional medicine focuses on symptoms
:arrow: Its objective is to prevent illness, keep people healthy and improve baseline health, whereas conventional medicine focuses on profit (medical visits, pharmaceutical drugs, glasses)
Ayurveda used to be the same as TCM. The difference is that TCM underwent minimal contamination throughout the centuries, while Ayurveda was heavily afflicted by the lies of Hinduism and Buddhism.
Other than this, bodybuilders are not the picture of health. They are hypertrophic, a word derived from Greek "excessive nourishment", and their pursuit is neither health nor strength but appearance. A bodybuilder isn't fit for a survival. They may do great at sprints because of leg development but would not be able to run for 10s of miles, especially while carrying load on their back. They are a poor example to look at. If anything, you could've said look at calisthenics athletes which, despite the many issues with their rushed training plans, at least look healthy and have more endurance than bodybuilders.
Gain and losing weight are a matter of mindset and overall lifestyle, not just of diet. If you don't have a supporting mindset and lifestyle, you can eat whatever fad diet (or even a balanced diet) but you'll never achieve health nor excellence, let alone positive body change. You could be able to stick to that diet but your body will not reshape properly.
Talking about eggs, you can't just eat proteins from the same source and only the same source. That's unhealthy. You need a VARIETY of protein sources in your diet. Meat, fish, poultry, seafood, eggs, fermented dairy, seeds, nuts, etc. Getting too much of the same DOES lead to imbalances as everything is your body is built on natural principles, not against nature. That's the real world. It's the same principle behind why fruit juices aren't so healthy. High protein diets also lead to excessive amounts of bilirubin, which is a byproduct of the bile. When protein in your diet is too much, you will find concentrations of it in your urine, because your kidneys have to work extra hard to get rid of it. Normally, urine should be clear in colour and make no bubbles. If it's not, you're either undergoing detox, drinking too little water or having other imbalances that need rectification.
As for seeing no studies that protein is not absorbed all the way, are you serious? Protein is the most difficult macronutrient for the body to break down. It requires a lot of heat. Part of it is lost to the heat, regardless of the source. You don't even need TCM to explain that, as conventional medicine knows it too.
