Conclusion: Evidence suggests that FA exercise can improve certain fall risk-related motor outcomes and reduce falls. Limited effects on strength and functional ability might be related to insufficient training intensity and lack of adherence. Further studies that include progressive strength and flexibility training are necessary to validate which FA exercise programs are most effective at preventing falls.

Conclusion: Over time, SFA and SFA-dominant TAGs declined, while UFA and UFA-dominant TAGs rose. These variations reflect shifts in maternal diet, infant nutritional needs, and potential growth outcomes, highlighting the importance of monitoring breast milk lipids to optimize infant nutrition strategies.
PubMed 40010192 ↗Conclusion: Moreover, the greatest transfer efficiencies of this fatty acid from diet to milk were recorded with the same 2 treatments, plus the mechanically processed whole seed. These results make this last category the most suitable treatment, among the 6 flax forms evaluated, to combine optimum lactation performance and protection of flax constituent cis-9,cis-12,cis-15 18:3.
