Nutritionist’s experiment: what happened after eating an apple every day for a week
A nutritionist ate one apple every day for a week and noticed her digestion became more regular. The informal experiment shows how a small daily habit can affect well-being, though it is not proof of long-term health effects.

There is a saying that if you eat an apple every day, you may need to visit the doctor less often. Nutritionist Lauren Manaker decided to test how much truth might be behind this idea, and for seven days she ate one medium-sized apple each day.
Manaker regularly reminds her clients that it is important to eat fruits and vegetables in everyday life, so when she was offered the chance to do this week-long experiment, she agreed. She says she did not expect drastic changes, but after seven days she noticed several things that surprised her.
How the experiment went
For the experiment, the nutritionist chose her favorite Honeycrisp apples, because she likes their sweet-and-sour taste and crunchiness. The plan was simple — eat one medium apple every day for a week and observe whether her well-being changed.
Manaker emphasizes, however, that such a one-week experiment is not a scientific study and cannot be used to draw conclusions about long-term health effects. Still, it allows observing whether such a small everyday dietary habit can influence how a person feels.
First observed changes
One of the first changes the nutritionist noticed was more regular bowel function. According to her, her digestion became more even over the week.
Thus, the experiment suggests that even a small daily habit like eating one apple can have an effect on well-being, at least in the short term.
