Infact
48 / 100
Mixed

The text states that only about 10% of the cells in the human body are human, while 90% are fungi and bacteria.

Infact verdict: Mixed (48/100).

The claims regarding the percentage of human versus microbial cells in the body are based on estimates and scientific studies. The evidence suggests that the ratio of human to microbial cells is closer to 1:1 rather than the previously believed 10:1 ratio. This means that the claim that only 10% of the cells are human is outdated and misleading. Current research indicates that the number of human cells is approximately equal to the number of microbial cells, including bacteria and fungi. Therefore, the claims are not entirely accurate based on the latest scientific understanding.

Only about 10% of the cells in the human body are actually human.
The claim that only about 10% of the cells in the human body are human is based on outdated estimates. Recent studies, such as the one published in PLoS Biology, suggest that the number of human cells is approximately equal to the number of microbial cells, contradicting the 10% figure. Therefore, the claim is misleading.

Mixed Science
90% of the cells in the human body are made up of various fungi and bacteria.
The claim that 90% of the cells in the human body are fungi and bacteria is based on outdated information. Current research indicates that the number of microbial cells is roughly equal to the number of human cells, not 90%. This makes the claim misleading.
