Common foods and farming methods thought to promote health: what the data show.

Abstract

What are the best dietary practices and farming methods to promote health? The answer may depend on whether one looks at the health of individuals or the health of the planet (planetary health or PH). PH will equate to a healthy ecosphere fostered by dietary/farming practices that are less resource-intense, potentially decreasing starvation and carbon emissions. Best practices also may depend on whether by health one means lack of observable disease (such as obesity, nutritional deficiency, diabetes, or cancer), optimal health (also known as wellness), or longevity. This article attempts to give an overview of the evidence as regards all of these aspects and definitions of health.
