This is true for any food though. A different line of argument would be what if 95% of your protein came from whey and all other nutrients came from other sources. As long as you get the right balance of macronutrients and micronutrients i suspect you will be fine. Unfortunately studies on diet are very difficult to actually implement so we don't have the data to be certain.
Obviously most ultra processed food is low in nutrition, high in sugar, and high palateability so it makes sense that ultraprocessed foods are associated with bad health outcomes but I think it's a step too far to say that all ultra processed food is bad (it's probably a good rule of thumb for most people however).
What? I've had >100g of protein from whey protein shakes every day for months now. I don't know what you're trying to imply.
I definitely feel a bit better, and have a much easier time building muscle.
If you run the numbers, you can actually eat a shocking amout of protein (300g+ / day) from lean meat while maintaining a calorie deficit.
And if you buy frozen chicken breasts from Costco, I think it’s actually cheaper than whey!
That said - you do you, whey has its place in many lifestyles.
And that’s assuming it contains (only) what the label says. Our caveman ancestors did not eat fillers.
How do you make that taste good though
"According to international consensus, the daily reference intake of protein for the healthy adult population is 0.8 g/kg body weight. However, individuals who engage in physical activity may require more protein, ranging from 1.2 to 2 grams per kilogram of body weight. To fulfill these requirements, many athletes and active individuals opt for whey protein (WP) supplements to increase their protein intake. The appropriate amount of WP intake for individuals depends on their objectives, current level of physical activity, and body composition. Research suggests that a dosage of 20 to 25 g/day of WP provides the desired benefits, while amounts >40 g/day may lead to adverse effects on the body"[0]
People who eat a lot of protein die sooner than people who eat less, but that is probably because plentiful protein prevents the body from entering a state called "autophagy". Intentionally inducing autophagy for 5 days every other month (by using Valter Longo's protocol) while eating plenty of protein the rest of the time is probably better for most people than a consistently low-protein diet as long as one is avoiding red meat (provided the people can afford the protein which will be the case for almost everyone in the developed world).
