Triglycerides are a type of fat also known as “lipids in blood. Triglyceride is an ester derived from glycerol and three fatty acids (from tri- and glyceride). Triglycerides are the main constituents of body fat in humans and other animals, as well as vegetable fat They are also present in the blood to enable the bidirectional transference of adipose fat and blood glucose from the liver, and are a major component of human skin oils Body converts extra calories especially from food such as pastries white bread, candy, sugar, oil, margarine, butter and alcohol into triglycerides and stores them in fat cells. Triglycerides play an important role in metabolism as energy sources and transporters of dietary fat. They contain more than double energy (approximately 9 kcal/g or 38 kJ/g) as carbohydrates (approximately 4 kcal/g or 17 kJ/g)
In the human body high levels of triglycerides have been linked to atherosclerosis, risk of heart disease and stroke. However, the relative negative impact of raised levels of triglycerides compared to that of LDL: HDL ratios is as yet unknown. The risk can be partly accounted for by a strong inverse relationship between triglyceride level and HDL-cholesterol level.
Triglycerides & Cholesterol are known as lipids but only triglycerides are fats. Cholesterol is a waxy substance made by liver and intestines that helps make cell membranes and hormones. It also helps body to digest food. Body uses them to transfer and store energy for later use. But higher level of bad LDL) cholesterol can raise risk of heart disease.
The levels of good (HDL) cholesterol bad (LDL) cholesterol and triglycerides in blood can be measured by Blood Test known as Lipid Profile. Desirable: Less than 150 mg/dL (1.7 mmol/L)
Borderline high: 150 to 199 mg/dL (1.7-2.2 mmol/L) High: 200 to 499 mg/dL (2.3-5.6 mmol/L)
Very high: 500 mg/dL or greater (5.6 mmol/L)
These levels are tested after fasting 8 to 12 hours. Triglyceride levels remain temporarily higher for a period after eating.
The American Heart Association recommends an optimal triglyceride level of 100 mg/dL (1.1 mmol/L) or lower to improve heart health.
For people with mildly or moderately high levels of triglycerides lifestyle changes including weight loss, exercise moderate exercise and dietary modification are recommended. This may include restriction of carbohydrates (specifically fructose) and fat in the diet and the consumption of omega-3 fatty acids from algae, nuts, and seeds. The decision to treat hypertriglyceridemia with medication depends on the levels and on the presence of other risk factors for cardiovascular disease.
