00:00A surprising new study is challenging what we know about healthy aging.
00:04Researchers at USC tested a special low-protein diet in older mice.
00:08The diet included carefully controlled levels of the amino acid methionine.
00:12The results were striking.
00:14The mice lived healthier for longer.
00:17They also had less body fat and showed less frailty.
00:20Most surprisingly, they preserved their lean muscle mass.
00:24Researchers also analyzed dietary data from more than 200,000 people.
00:28Those consuming the most animal protein had higher obesity levels.
00:33They also had twice the diabetes rate compared with people eating little or no animal protein.
00:38But researchers say this does not prove that animal protein causes these conditions.
00:43The human findings were observational.
00:46And the mouse results may not translate directly to people.
00:50Researchers now hope to test the diet in controlled human trials.
00:53The goal? Find the right protein balance for healthier aging.
