Background: The aim of this study was to evaluate the nutritional effects of supplementation with virgin coconut oil (VCO) in Wistar rats over a sub-chronic period (6 weeks).Methods: Twelve Wistar rats were used and randomly assigned to receive (n = 6): control - lab chow; coconut oil (CO) - lab chow with added virgin coconut oil (20%). Food and caloric intake, weight gain, food efficiency, body mass index, femur and tibia length, bone mineral composition and blood biochemistry were evaluated.Result: The CO group showed an energy intake closed to control group. Also, the supplementation with VCO generated a decrease in total blood cholesterol as compared to the control group. However, the CO group showed accumulation of fat mass, shorter femur length and anxiogenesis in relation to the control group. These results indicate few beneficial effects from the sub-chronic use of VCO and indicate that its consumption in large quantities for long periods should be questioned.

BACKGROUND: Research has shown that the decrease in the inner diameter of vessels caused by hyperlipidemia lowers the capacity for blood oxygen delivery to the cochlea. This leads to impaired cochlear metabolism and causes hearing problems. OBJECTIVE: The effects of dyslipidemia on noise-induced hearing loss in workers were examined. METHODS: This descriptive cross-sectional study was performed on 692 male employees in a petrochemical industry in the southwest of Iran exposed to 85 dB noise. Clinical audiometry and blood sample tests were used to evaluate the hearing and prevalence indices of dyslipidemia (cholesterol, triglyceride, HDL and LDL). The data were analyzed using SPSS software version 25 (p = 0.05). RESULTS: The results showed that the prevalence of dyslipidemia was 24.5%with abnormal relative triglyceride frequency of 49.5%, HDL of 28%, LDL of 33%, and total blood cholesterol level of 37.8%. There was no significant relationship between NIHL and dyslipidemia (p >  0.09). However, the major NIHL drops at different frequencies were in the individuals with dyslipidemia. The parameters age and dyslipidemia increased NIHL odds ratio (95%C.I.). by 1.130 (1.160–1.100) and 1.618 (2.418–1.082) respectively CONCLUSION: The rate of hearing loss in individuals with dyslipidemia increases at different frequencies and it leads to an increase of the OR of NIHL in individuals with dyslipidemia. We can control dyslipidemia and its effective factors. The NIHL is more common in people exposed to noise.
