Guyana is the only country in the world that can fully sustain itself with food from all 7 major groups - meat, dairy, fish, starchy foods, legumes, fruits, and vegetables. China and Vietnam follow closely, covering 6 out of 7 groups, while various European, Asian, and Latin American countries, along with Australia and New Zealand, can manage 5 out of 7.

On the flip side, Yemen, Iraq, and Afghanistan face significant challenges in food security as they fall short in meeting their needs across all food groups. Meanwhile, many African nations and Japan struggle as they can only provide for one food group, highlighting the global disparities in food self-sufficiency.
