Sugar Intake During Antibiotics Linked to Gut Microbiome Damage

Endocrinologist Zohra Pavlova has stated that avoiding sweets during antibiotic treatment can help protect the intestines from various complications. Her advice is grounded in findings regarding the impact of dietary sugar on gut health when combined with medication.

Nature Study on Sugar and Bacteria

Pavlova references results from a US study published in the journal "Nature." The research demonstrated that consuming every 100 grams of sugar daily reduces intestinal bacterial diversity by 24%. This significant drop in beneficial microbes creates an environment where harmful organisms can thrive.

According to the specialist, when levels of beneficial bacteria decrease and sugar intake rises, harmful microbes—particularly enterococci—begin to colonize the intestines. In vulnerable patients, this colonization can lead to severe blood infections and immune system complications.

Mechanism of Pathogen Growth

Experiments conducted on mice confirmed that elevated sugar levels cause pathogenic growth specifically when antibiotics are administered. The study noted that a diet rich in sugars does not produce these same consequences in the absence of antibiotic treatment. Pavlova described limiting sugar intake during antibiotic use as a simple, safe, and free method to protect the microbiome and accelerate recovery.

Dietary Recommendations for Recovery

The physician outlined additional strategies to mitigate damage caused by antibiotics. She recommended that patients drink at least 1.5 liters of water daily. Furthermore, she advised incorporating fermented dairy products and plant fibers into the diet, specifying a daily intake of 400 to 600 grams of vegetables.

Pavlova also urged patients to limit their consumption of sweets, fatty foods, fried items, pickles, salty foods, and other substances that burden the liver. These dietary adjustments aim to support overall physiological resilience during treatment.

Role of Methionine-Rich Foods

In addition to fiber and hydration, Pavlova recommended adding foods rich in methionine to the patient's diet. Methionine is a sulfur-containing amino acid essential for protein structure. Suitable sources include fish, seafood, legumes, nuts, eggs, low-fat cheeses, cottage cheese, poultry, and other types of meat.
