In brief
sugar and fertility: this page reviews Cumulative sugar intake (all sources combined) (Overall glycemic load) — documented mechanism, everyday exposure situations and possible alternatives. Level of evidence: Probable.
- Where it's found
- Added sugars present in most processed foods (sauces, industrial bread, ready meals, cereals), in addition to sugary drinks.
- Suspected mechanism
- Daily accumulation of hidden sugars, beyond drinks alone, promotes insulin resistance, itself linked to ovulation disorders and less favorable sperm parameters.
- Suggested alternative
- Check labels for added sugars (not just drinks): sauces, breakfast cereals and industrial bread often contain more than expected.
- Source
- Nurses' Health Study II; literature on glycemic load and ovulation.
