The figures are rounded to the nearest 50,000, with Kendall adding this meant "small variations" in the underlying numbers could "lead to much larger changes in the rounded headline numbers".

Despite living in connected coastal waters, piangua populations in different areas maintain subtle genetic variations.

"We felt these four diet scenarios gave us a good variation of diet types from low meat to higher quantities of meat and dairy while also maintaining cultural relevance," noted DeCesaro.

"This research opens possibilities for personalised meal plans for astronauts and individuals living alone on Earth, showcasing VR's potential to explore variations in eating when stressed," she said.
