Russian nutrition expert Dr. Yelena Solomatina indicated that elderly individuals should not overconsume fruit as it can lead to health issues, including obesity and diabetes. The expert notes that "fructose and fiber in fruits contribute to this. Additionally, consuming a large amount may lead to fatty liver disease, as the liver will attempt to compensate for the fructose and may not function normally. Another negative effect of excess fruit in the diet is allergies."
She states, "Allergies often develop from fruits, especially those that are red in color. Of course, a small amount may cause no issues, but excessive consumption can lead to problems. Therefore, moderation is key." According to the doctor, in old age, when there are no contraindications, it is advisable to consume only two pieces of fruit per day—one in the morning and one after lunch.
It is noted that experts from the World Health Organization and the International Agency for Research on Cancer recommend consuming around 400 grams of fruits, nuts, legumes, and vegetables daily, divided into five portions. This daily guideline also includes juices and dried fruits.
