Virtually every food consumed by humans is originally derived from sunlight. 

How is meat ultimately derived from sunlight?

• 
  Animals utilize the heat from the sun for body temperature which supports the metabolic processes necessary to make muscle tissue

• The animals are mostly diurnal and will only eat during the day. Thus, the sun provides the light needed to support this diurnal lifestyle

• Animals require sunlight to survive and thrive so the meat that people consume is supported by sunlight

• The animals are fed a plant-based diet and use that energy (originally derived from the sun) to build the proteins that people consume when they eat meat
