How much fructose can a normal person consume per day at most?

There is no such thing as a "maximum daily fructose intake for healthy individuals." Under normal circumstances, it is recommended that healthy individuals consume 30–40 grams of fructose per day. The detailed analysis is as follows:

Fructose is found in various foods such as honey, apples, and grapes, and helps maintain normal bodily functions. The human body requires an appropriate daily intake of fructose, which offers multiple health benefits including maintaining blood glucose balance, protecting the liver, and providing energy.

However, healthy individuals should consume fructose in moderation—around 30–40 grams per day—to avoid excessive intake that may lead to obesity, gout, diabetes, and other health conditions. Overconsumption can also irritate the gastrointestinal mucosa, increase the burden on the digestive system, cause indigestion, and lead to symptoms such as bloating, acid reflux, and loss of appetite.

Although fructose contains many nutrients, certain populations such as individuals with diabetes or those prone to allergies should avoid consuming it to prevent adverse health effects. It is advisable to maintain a balanced diet and engage in regular physical activity when consuming fructose to support overall health.
