Protein is perhaps the one macronutrient that many people are most obsessed with. “Where do you get your protein if you don’t eat meat, dairy and eggs?” As if plants don’t have protein.
Meat, dairy and eggs are often hailed as being “high quality” because they are efficiently used to promote growth. This would be good if high quality and high efficiency equal great health, but in this case, they don’t. Compelling research shows that “low quality” plant protein is in fact the healthiest type of protein, allowing for slow but steady synthesis of new proteins.
The protein from meat, dairy and eggs are very dense and monotonous (contain very few amino acids that make up the protein). Our body has a hard time breaking these dense proteins down in the small intestine, so we end up with a large amount of undigested food in the colon which places a high demand of fermentation.
In a study on young healthy adults, a typical modern day meal (consisting of meat and dairy) takes 14 hours of transit time to get to the colon, compared to only 90 minutes transit time for a plant based meal.
In other words, if you eat chicken for lunch, 14 hours later you are still digesting that protein load from the chicken, trying to get it through to the colon. Meanwhile, you’ve also eaten dinner with another piece of animal protein, which will take until the next day to get through to the colon. You can imagine the load on the small intestine to digest all these animal proteins slowly, clogging up the colon with high demands of fermentation.
Where do you get your protein on a plant based diet? Now where do cows get their protein from?
