The study included a group of breastfeeding mothers from Salah al-Din Governorate and the surrounding villages, and the nursing mothers were divided into two groups and the number of breastfeeding mothers in each group was 6 mothers, three mothers in the city and three mothers in the village, and they were given nutritional supplements for vitamins and fatty acids, both according to his group. Results for breastfeeding mothers' milk before and after giving them nutritional supplements, there are differences in the levels of vitamins and fatty acids. It was noticed that the level of vitamins in the milk after nursing mothers took the nutritional supplement differed, so it was retinol (242-268) μg / L for mothers in the city and (213-260). g / L for mothers in the village and β--carotene (320-367) μg / L for mothers in town and (315-361) μg / L for mothers in the village and α-tocopherol (182-279) g / L for mothers in town and (120-225) μg / L for mothers in the village and calciferol (309-382) μg / L for mothers in the city and (258-269) μg / L for mothers in the village. As for the omega group for breastfeeding mothers, the levels of fatty acids in their milk were after Breastfeeding mothers take a nutritional supplement only and Mega (3,6,9) all fatty acids in the milk of breastfeeding mothers increased, so it was for lauric acid (18.02-20.01) mg / L for mothers in the city and (18.02-20.11) mg / L for mothers in the village and for palmitic acid (18.07-24.25) mg / L for mothers in the city and (24.25-26.15) mg / L for mothers in the village and for oleic acid (14.09-29.93) mg / L for mothers in the city and (29.43-29.13) mg / L for mothers in the village and for linoleic acid (22.13-28.16) mg / L for mothers in the city and (22.11-22.14) mg / L for mothers in the village, and for linoleic acid (22.26-26.59) mg / L for mothers in the city and (26.15-26.54) mg / L for mothers in the village and for Arachidonic acid (12.94-18.15) mg / L for mothers in the city and (12.94-18.15) mg / L for mothers in the village, and this explains that breast milk is directly affected by the nutritional intake and nutritional supplements taken by breastfeeding mothers during the breastfeeding period

This study was conducted at the Iraqi Center for Cancer Research / Al-Mustansiriya University / Baghdad Governorate, for the period from November 2020 to January 2021, to know healthy effects of different fat ratios mixtures of Omega-3 to Omega-6 in male mice with type 2 diabetes induced by Aloxan at a concentration of 100 mg / kg of weight. 32 mice aged (2-3) months and their weight (25-30) g were included. Four mice were isolated from them as a healthy control group and the remaining mice were injected with alloxan. Infected mice were divided into seven groups, one of which was untreated group (infected control), while the rest were treated with mixtures of different proportions of omega 6 and 3 fats. After the 30-day experiment, the biological study showed that the introduction of experimental diabetes mellitus with alloxan led to a higher Significant (p>0.01) and (P>0.05) in the concentration of glucose, total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein-cholesterol (VLDL-C) compared with the proper control group. While it led to a significant decrease (p>0.01) and (p>0.05) in high-density lipoprotein-cholesterol (HDL-C) concentrations in the affected control group, but when using mixtures of different proportions of omega-6 fats: Omega-3 led to a decrease in the concentration of glucose, total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein-cholesterol (VLDL-C) compared with the infected and untreated control group and an increase in concentrations of high-density lipoproteins (HDL-C) cholesterol.
