4. Conclusion
Although extreme intolerance may require exclusively lactosefree
milk, most people with hypolactasia, if given appropriate
advice, can tolerate some lactose-containing foods without
symptoms (Lomer et al., 2008). It is generally accepted that 50–
80% lactose reduced milk will satisfy the physiological requirements
of the majority of intolerant groups (Indyk et al., 1996) so
that it would be possible to elaborate a low-lactose milk with a
noticeable GOS content.
