Phytonutrients /
Plants are a major source of nutrition in our diet, and offer an array of health benefits, yet many Western diets are still over-reliant upon animal-based foods. Growing evidence suggests that this emphasis on foods of animal origin may be linked to increased incidences of cancer and cardiovascular...
