Level 1 - Absolute Beginner
Scientists studied nearly 200,000 people. They looked at when people eat.
Some people eat late, after dinner or near bedtime. These people had more liver disease.
The liver cleans the blood and helps the body. The study does not prove late food is the cause. But it is a good reason to think about meal times.
- liver
- a body part that cleans blood and helps digestion
- disease
- an illness
- dinner
- the main meal in the evening
- bedtime
- the time you go to sleep
- study
- careful research
- risk
- the chance that something bad happens
- blood
- the red liquid in your body
- meal
- food eaten at one time
Level 2 - Elementary
Researchers led by Oregon Health and Science University looked at data from nearly 200,000 people. They asked a simple question: does it matter when you eat?
People who regularly ate after dinner or around bedtime had a 20 to 30 percent higher risk of liver disease than other people. The liver helps the body use food and clean the blood.
The study found a link. It did not prove that late meals cause liver disease. People who eat late may also sleep less, eat more or choose different foods. Doctors say good sleep and balanced meals still matter.

- a person who studies a subject to find new facts

Level 3 - Intermediate
An analysis led by Oregon Health and Science University has linked the habit of eating after dinner or around bedtime to a higher likelihood of liver disease. Using data from nearly 200,000 people, the team found that regular late eaters had a 20 to 30 percent greater risk than those who finished eating earlier.
Scientists have long suspected that the body handles food differently at night. The liver follows a daily rhythm, and meals eaten when it expects to rest may encourage fat to build up there. Late eating can also go with poorer sleep, snacking and heavier meals, all of which may play a part.
The researchers stress that the work is observational. It shows an association, not a cause, and it cannot rule out other differences between people who eat late and people who do not. Still, the finding adds weight to advice that many nutrition experts already give: leave a few hours between your last meal and bed.

- nutrition
- the study of food and how it affects health
- encourage
- to make something more likely
Level 4 - Advanced
A study led by Oregon Health and Science University has tied the habit of eating after dinner or around bedtime to a heightened incidence of liver disease. Drawing on records from nearly 200,000 people, the investigators calculated that regular late eaters faced a 20 to 30 percent greater risk than those who finished their last meal earlier in the evening.
The biology is plausible. The liver runs on a circadian schedule, and nutrients arriving when the organ is primed to rest may favor fat accumulation. Late meals also tend to travel with disrupted sleep, mindless snacking and larger portions, any of which could contribute independently.
The authors are careful to describe the work as observational: it identifies a correlation, it cannot establish causation, and it cannot entirely exclude confounding differences between night eaters and everyone else. Even so, the finding lends empirical heft to a piece of advice that dietitians have long offered on instinct, namely that the last meal should come a few hours before bed.
