Excellent find brother! By studying human anatomy, it is apparent that meat is not our natural diet, we are more adapted for a fruit-based diet. There are exceptions to this, Jordan Peterson for example, lives on an all-meat diet which he claims to have transformed his life. Sri Yukteswar advice a simple diet that is suitable for one's constitution, I think this is a good rule of thumb to go by. Most monks, yogis, and people on the spiritual path prefer a vegetarian diet. Again, there are exceptions, take Tibetan monks for instance, though one can argue that they consume meat out of circumstance. From a karmic and environmental perspective, a meat-free diet is definitely something to be strived for.
