Conclusion
This Systematic Review and Meta-Analysis has achieved its objective to investigate the relation of oxidative stability of different vegetable oil as well as the subsequent risk of developing adverse health implications by drawing together data from multiple studies. Results were found to be robust in several meta-analyses with significant value (P < 0.05) stratified on study characteristics and inspected the relationship between heated vegetable oils and induced diseases through a controlled inclusion of studies. These findings thus underscore the absence of mentioned diseases or disorders regarding chronic consumption of a diet with repeatedly heated cooking oils except in SFO. The clinical significance of results from meta-regressions should be acknowledged as it debunked the conception of ingestion of all types of thermally heated oils in diet will cause Alzheimer’s disease, obesity, Type 2 Diabetes, events of cardiovascular disease and eventually metabolic syndrome.
