Triglycerides are involved in the transport of fatty acids to muscles and tissues for energy. HDL particles are involved in the transport of excess fatty acids from the periphery back to the liver for elimination. Because of these competing roles, it is very difficult to increase HDL, the healthy good cholesterol, without first addressing triglycerides. HDL not only transports excess lipid to the liver for disposal, it transports cholesterol to organs such as the adrenals, ovaries, and testes for steroid hormone synthesis. Many of the strategies discussed here that lower triglycerides are also known to raise HDL.
Vitamin D . I am a fanatic for correcting vitamin D deficiency in people. Having now corrected vitamin D blood levels in over 1000 patients for up to three years, I am nothing but thoroughly impressed with the range of wonderful benefits that develop, such as reduced blood sugar, increased bone density, gradual relief from arthritis, elimination of winter "blues," and many others. Among the rarely appreciated benefits of vitamin D is a reduction in triglycerides. I am uncertain why this develops, but I suspect that at least part of the effect arises from vitamin D’s ability to normalize reduce blood sugar and insulin responses, both of which help reduce triglycerides.
Raised triglycerides often go hand in hand with low HDL levels . The higher the triglyceride level the lower the HDL level. Why is this? The explanation is complex, but put simply; as the main triglyceride carrying particles give up their
triglycerides they also transfer cholesterol to HDL . When triglycerides are cleared from the blood less quickly, less cholesterol is transferred to HDL particles meaning HDL cholesterol levels remain low. This is why it is important to have a full lipid profile (total cholesterol, triglycerides and HDL cholesterol), know and understand your numbers.
