A study out of Denmark on the effects of fish oil on the blood chemistry of diabetics found that fish oil supplements increased the amount of “good” cholesterol and decreased the amount of fatty substances in their blood:
Their study of 42 adults found that those who took a supplement with 4 grams (g) of fish oil for eight weeks lowered their levels of triacylglycerol (TAG), a fatty substance linked to heart disease. Their levels of two subtypes of the “good” cholesterol known as HDL also rose.
The researchers made the following conclusion:
“In conclusion, fish oil supplementation was found to partially correct the dyslipidemia (abnormal blood fats) of type 2 diabetes,” the researchers write. However, “the predominancy of small dense LDL particles–was unaffected by fish oil.”
