Answer: But it's also common to choose a plant-based diet because it's considered healthier. And that's for good reason. Research over many years has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers (as compared with diets high in meat and other animal products

Is a meat based diet better than a plant-based diet? Answer: Mounting evidence shows that reducing meat and increasing plant-based protein is a healthier way to go. A diet with any type of meat raises the risk of heart disease and cancer, when compared with a vegetarian diet.”

Plant-based diet: A plant-based diet or a plant-rich diet is a diet consisting mostly or entirely of plant-based foods. Plant-based foods are foods derived from plants with no animal-source foods or artificial ingredients. While a plant-based diet avoids or has limited animal products, it is not necessarily vegan.

Meat is a complete, high-quality protein containing all of the essential amino acids your body needs for optimal health.


Meat provides more protein per serving (25 grams per 3 ounces) than dairy (8 grams per cup), eggs (6 grams each), legumes (12 grams per ¾ cup), vegetables or nuts (2 to 5 grams per serving).

In action potential, calcium ions may control gene transcription, cell excitability, and neurotransmitter release. In chemical synapses, the influx of calcium ions leads to vesicles filled with neurotransmitters move to the surface of the cell, and into the synaptic cleft release their contents.
