Managing Your Cholesterol 1 What is Cholesterol? A waxy substance – technically a sterol (unsaturated steroid alcohol) 75% of your cholesterol is made in your liver, the rest is absorbed from food Cholesterol travels in particles called lipoproteins: high-density lipoproteins (HDL) and low-Density Lipoproteins (LDL) 2 Where does Cholesterol come from? The Liver Makes Cholesterol and secretes it into the blood Regulated by receptors in the liver Genetics genetic predisposition for familial hypercholesterolemia Diet High saturated fat intake 3 Types of Cholesterol HDL considered the 'good' cholesterol LDL considered the ‘bad' cholesterol Contains a higher level of protein than cholesterol Higher level of cholesterol than protein HDLs transport cholesterol from the tissues of the body to the liver, so the cholesterol can be eliminated in the bile. LDLs tend to stick to damaged or inflamed areas of blood vessel walls and form plaque buildup The higher the LDL cholesterol level, the higher the risk of coronary artery disease. The higher the HDL cholesterol level, the lower the risk of coronary artery disease. 4 5 What are Triglycerides? Triglycerides are a type of fat (lipid) found in your blood Your body converts any calories it doesn't need to use right away into triglycerides Triglycerides are stored in your fat cells Hormones release triglycerides for energy between meals Regularly eat more calories than you burn will raise triglycerides and increase fat storage 6 What is the difference between Cholesterol and Triglycerides? Recommended rang is below 150. Triglycerides store unused calories Cholesterol used build and repair cells High triglycerides are often a sign obesity and metabolic syndrome High triglycerides can be a sign of poorly controlled type 2 diabetes, low thyroid hormones (hypothyroidism), liver or kidney disease High triglycerides could also be a side effect of taking medications (beta blockers, birth control pills, diuretics, steroids or some chemotherapies). 7 Why do we need Cholesterol? Your body uses cholesterol to make: Vitamin D sex hormones (testosterone, estrogen, progesterone) Stress hormones (cortisol) bile acids for digestion Contributes to normal membrane function of nerve cells in the brain Serves as an antioxidant (Neuroprotective) 8 Current Recommendations 9 How can we control cholesterol? Diet: Minimize sweets and refined carbohydrates (i.e.: white bread, candy). Excess sugar increases triglyceride levels contributing to cholesterol production. Increase consumption of healthy fats Consume carbohydrates with proteins and fats to slow breakdown. Reduce portion sizes to control calorie intake. Increases satiety, reduces insulin response helps maintain normal weight and sugar metabolism Increase Fiber intake Exercise: Physical activity increases cellular energy needs Increases ration of good to bad cholesterol Stress Reduction: Reduces stress hormone (cortisol) response, reducing blood pressure and blood sugar. Medication and/or supplements 10 *same as blood sugar regulation Healthy Fats 11 Hidden Dangers High Cholesterol The incubation period for this disease can be up to 10 to 20 years. Metabolic disruptions are present long before physical symptoms. Reduces overall quality of life feelings of wellbeing. Accelerates development of other health issues: hypertension, heart disease, dementia. 12 *same as blood sugar regulation Complications of long term elevated Cholesterol 13 14
