The latest study reveals that the food system contributes to almost 30 percent of the total greenhouse gasses emissions in the United States. This number contributes to the environment's global warming issues. Most of the food items included in the food system that has the most significant contribution to global warming are animal-based food.

The Science Daily reports that a good healthy diet can expressively contribute to a healthier environment. Leaning to a healthier diet, including fruits and vegetables, can decrease greenhouse gasses being released into the environment, which is the primary cause of global warming.

The findings from the new study conducted by US Santa Barbara researchers have published in the journal Climatic Change was a first since most research leaning on global warming focused on technologies that have created too much of these greenhouse gasses. The study analyzed the potential effect of healthier food models for the United States in fighting against global warming. It was also found that the poor quality of the standard US diet, is also a major factor that leads to preventable diseases. A typical food system diet in the US consists of high levels of red and processed meat and low levels of fruits and vegetables.

Similar studies posted at the Los Angeles Times also reveals that our ancestors, Neanderthals, had a very striking difference in their diet. Their choice of diet depended on the place they lived. Those living near the rivers had mostly fish as their primary diet while others who lived inside forests consumed nuts and fruits. This explains why most of them are illness free and enjoy a healthier environment than what we have today.

The findings posted earlier in the journal Nature revealed that a typical Neanderthal diet is close to that of a vegetarian. The team studied samples from one Neanderthal from Belgium and two from El Sidron Cave in Spain, around 36,000-years old and 48,000-years old respectively. The Spanish Neanderthal was found to have eaten plenty of mushrooms, pine nuts, and moss, a diet available in a dense forest and showed no traces of meat.

History and latest studies also reveal that the food choices that man makes contribute not only to his own benefit but as well as the environment in general. Leaning into a healthier diet is synonymous to a healthier environment and would probably help man's problem in fighting against global warming.
