Going to the actual research
Researchers in Animal Frontiers said that unprocessed meat is responsible for providing B12 vitamins, omega-3 fatty acids, and minerals, such as iron and zinc, as well as supplying retinol.
The paper suggested that the link between red meat and disease was almost eradicated when it was combined with a healthy diet, leading to the suggestion it was the rest of the diet that is the cause behind health issues.

Aspects of human anatomy, digestion, and metabolism diverged from other primates, indicating evolutionary reliance on, and compatibility with, substantial meat intake. Implications of a disconnect from evolutionary dietary patterns may contribute to today’s burden of disease, increasing the risk for both nutrient deficiencies and chronic diseases.
Meat supplies high-quality protein and various nutrients, some of which are not always easily obtained with meat-free diets and are often already suboptimal or deficient in global populations. Removal of meat comes with implications for a broad spectrum of nutrients that need to be accounted for, whereas compensatory dietary strategies must factor in physiological and practical constraints.
