00:00Could eggs help keep your brain healthier as you age?
00:02A new study says the nutrient choline may play an important role.
00:06Researchers found people with obesity had lower choline levels in their blood.
00:11They also showed more inflammation and markers linked to nerve cell damage.
00:15Scientists say these changes could appear years before Alzheimer's symptoms develop.
00:20But experts stress the study does not prove that low choline causes the disease.
00:25Around 90% of Americans don't get enough choline in their daily diet.
00:30Egg yolks are one of the best sources, along with fish, dairy, beans, and broccoli.
00:36Researchers say eating a balanced diet with enough choline may support long-term brain health, while more studies continue.
