What Are Sources Of Cholesterol
Cholesterol is an important substance found in all cells of the body. It is a waxy, fat-like substance required by the body to build healthy cells, hormones, vitamin D, and substances that help in digestion of food. Excess cholesterol is harmful to the body. Cholesterol usually comes from the following sources:
- Liver: It makes the cholesterol that is required for the body.
- Food: The remainder of the cholesterol in the body comes from foods derived from animals . These foods are usually high in saturated and trans fats. These fats may cause the liver to produce more cholesterol this added production means excess cholesterol, which is harmful for the body.
- Some tropical oils: Oils such as palm oil, palm kernel oil, and coconut oil if consumed may trigger the liver to produce more cholesterol. These oils are often found in baked goods.
What To Know About Triglycerides
In addition to cholesterol, you might hear about your triglycerides, another kind of fat found in the bloodstream. Women should pay particular attention to this. A high level of triglycerides seems to predict an even greater risk for heart disease in women compared with men, says Michos.
When you take in more calories than you need, your body converts the extra calories into triglycerides, which are then stored in fat cells. Triglycerides are used by the body for energy, but people with excess triglycerides have higher risk of medical problems, including cardiovascular disease. Drinking a lot of alcohol and eating foods containing simple carbohydrates , saturated fats and trans fats contributes to high triglycerides. High levels may also be caused by health conditions such as diabetes, an underactive thyroid, obesity, polycystic ovary syndrome or kidney disease.
Triglycerides also circulate in the bloodstream on particles that may contribute to plaque formation. Many people with high triglycerides have other risk factors for atherosclerosis, including high LDL levels or low HDL levels, or abnormal blood sugar levels. Genetic studies have also shown some association between triglycerides and cardiovascular disease.
Why Cholesterol Matters For Women
Ah, cholesterol and triglycerides. We hear about them all the time. Even foods that might seem good for you on the surface, like fruit-filled yogurt or bran muffins, can contribute to abnormal levels if they contain too much saturated fat or refined sugar, says Erin Michos, M.D., associate director of preventive cardiology at the Ciccarone Center for the Prevention of Heart Disease.
Whats more, many women are at risk for high cholesterol and dont realize it. Approximately 45 percent of women over the age of 20 have a total cholesterol of 200 mg/dl and above, which is considered elevated but a survey by the American Heart Association found that 76 percent of women say they dont even know what their cholesterol values are, Michos says.
Scarier still: Triglycerides, a type of blood fat typically measured alongside cholesterol, are even more risky in women compared with men. This is a problem because womens cholesterol levels can fluctuate quite a bit after menopause and tend to increase with age, putting us at greater risk of heart disease and stroke. Knowing your cholesterol numbers and how to control them is a big step toward staying healthy.

What Is A Healthy Cholesterol Level
According to the NHLBI, your risk for heart disease and other health problems, such as diabetes, increases if you have an HDL cholesterol level of 40 milligrams per deciliter or less for men and 50 mg/dL or less for women. The institute recommends that total daily cholesterol intake be less than 200 mg/dL, and that LDL cholesterol be less than 100 mg/dL.
Types Of Healthy Fats To Incorporate Into Your Diet
To get you started, Dr. Paul recommends incorporating more avocado, fatty fish , nuts, seeds, olive oil, coconut , and full-fat yogurts. Dairy is also a great source of fat, so if youre looking for a filling snack, grabbing a cheese stick is a great place to start. Here are 20 other healthy fats you can incorporate into your daily eating.
It is ideal to have 100 g of dates or a handful of dates every day to get all the essential nutrients. Though the quantity to be consumed may differ from person to person based on calorie needs and underlying health conditions. You may refer to a nutritionist to know how many dates you need to eat every day. A 100 g serving of dates on average contains:
- Calories: 314 kcal
- Sugar: 66 grams
Apart from minerals and vitamins, dates are the best source of antioxidants. Dates are rich in a trace mineral called selenium that may decrease the risk of bladder cancer and prostate cancer.

Eating Tips To Lower Your Cholesterol
- Limit saturated fats and trans fats. These fats are found in butter, margarine, partially hydrogenated oils, and shortening.
- Limit the amount of cholesterol you eat to 200 mg/day
- Try to eat 2030 grams of fiber a day. Fiber is found in fruit, vegetables, and whole grains. Some examples of whole grains are 100 percent whole wheat bread, whole grain pasta, and brown rice.
- Add Omega-3s to your diet. Omega-3s are found in canola oil, ground flaxseed, and fish, such as salmon or tuna.
- Eat more plant-based foods rather than animal-based foods. Protein found in beans and nuts will help keep cholesterol levels in check.
- Fat should make up only 2535 percent of the food you eat each day.
- Limit how much sodium you eat to 2400 mg/day. Salt is mostly sodium, and it is used in a lot of processed foods. Be sure to check labels to see how much sodium is in your food. Avoid adding salt.

Signs Of Deficiency And Toxicity
Deficiency
A niacin deficiency is rare in the United States and other industrialized countries because it is well-absorbed from most foods and is added to many foods and multivitamins. A severe niacin deficiency leads to pellagra, a condition that causes a dark, sometimes scaly rash to develop on skin areas exposed to sunlight bright redness of the tongue and constipation/diarrhea. Other signs of severe niacin deficiency include:
- Depression
- Hallucinations
Groups at risk for deficiency
- Limited diets. People whose diets are limited in both variety and quantity of foods, such as those living in poverty or who are very ill and cannot eat a balanced diet, are at increased risk. Developing countries that eat corn or maize as a main food source are at risk for pellagra, as these foods are low in both absorbable niacin and tryptophan.
- Chronic alcoholism. The absorption of several nutrients, particularly water-soluble vitamins including the B family, is decreased with excessive alcohol intake.
- Carcinoid syndrome. This is a disease of slow-growing cancer cells in the gut that release a chemical called serotonin. The syndrome causes tryptophan in the diet to be converted into serotonin rather than niacin, which increases the risk of decreased niacin.
Toxicity
Other signs:
- Blurred vision
- Impaired glucose tolerance and inflammation of liver in severe cases

High Cholesterol In The United States
- In 20152018, nearly 12% of adults age 20 and older had total cholesterol higher than 240 mg/dL, and about 17% had high-density lipoprotein cholesterol levels less than 40 mg/dL.1
- Slightly more than half of U.S. adults who could benefit from cholesterol medicine are currently taking it.2
- Nearly 94 million U.S. adults age 20 or older have total cholesterol levels higher than 200 mg/dL. Twenty-eight million adults in the United States have total cholesterol levels higher than 240 mg/dL.1
- 7% of U.S. children and adolescents ages 6 to 19 have high total cholesterol.1
- High cholesterol has no symptoms, so many people dont know that their cholesterol is too high. A simple blood test can check cholesterol levels.
- Having high blood cholesterol raises the risk for heart disease, the leading cause of death, and for stroke, the fifth leading cause of death.

Whole Milk: 488 Mg 16% Dv
Whole milk is rich in cholesterol and saturated fat, providing 16 percent of the DV for cholesterol and 46 percent of the saturated fat DV per 16-ounce serving.
Whole milk can increase HDL more than skim milk, according to a February 2018 study in the European Journal of Clinical Nutrition. The study also found that whole and skim milk had similar effects on LDL cholesterol and triglycerides, even though whole milk has more cholesterol and saturated fat.

Theres A Lot Of Conflicting Information About Saturated Fats Should I Eat Them Or Not
The American Heart Association recommends limiting saturated fats which are found in butter, cheese, red meat and other animal-based foods, and tropical oils. Decades of sound science has proven it can raise your bad cholesterol and put you at higher risk for heart disease.
The more important thing to remember is the overall dietary picture. Saturated fats are just one piece of the puzzle. In general, you cant go wrong eating more fruits, vegetables and whole grains and taking in fewer calories.
When you hear about the latest diet of the day or a new or odd-sounding theory about food, consider the source. The American Heart Association makes dietary recommendations only after carefully considering the latest scientific evidence.

Eating 2050 Grams Per Day
This is where the low carb diet has bigger effects on metabolism. This is a possible range for people who want to lose weight fast, or have metabolic problems, obesity, or diabetes.
When eating less than 50 grams per day, the body will go into ketosis, supplying energy for the brain via so-called ketone bodies. This is likely to dampen your appetite and cause you to lose weight automatically.
Carbs you can eat include:
- some berries, maybe with whipped cream
- trace carbs from other foods, like avocados, nuts, and seeds
Be aware that a low carb diet doesnt mean its a no-carb diet. Theres room for plenty of low carb vegetables.

Living With High Cholesterol
If you have high cholesterol, you are twice as likely to develop heart disease. That is why it is important to have your cholesterol levels checked, especially if you have a family history of heart disease. Reducing your LDL bad cholesterol through good diet, exercise, and medicine can make a positive impact on your overall health.
What Is Bad Cholesterol
Cholesterol moves in the body combined with proteins. This combination of cholesterol and proteins is called lipoproteins. The low-density lipoprotein or LDL cholesterol is called bad cholesterol. High levels of this cholesterol increase risk for heart diseases and stroke.
When you have high levels of LDL cholesterol in the body, the LDL cholesterol can accumulate on the walls of the blood vessels forming a plaque. The continuous cholesterol build-up or a plaque narrows the inside of the blood vessels with time. The narrowed blood vessel hampers the blood supply to the concerned organ. Thus, when the plaque is present in the heart, it can cause angina or a heart attack. Plaque build-up in the brain can cause a stroke.
Another type of cholesterol is HDL cholesterol. It is also called good cholesterol as it absorbs cholesterol and carries it back to the liver. The liver then removes the cholesterol from the body. HDL cholesterol, thus, can lower your risk for heart diseases and stroke.

Fast Facts On Cholesterol:
- Cholesterol is an essential substance that the body produces but which people also consume in foods.
- Risk factors for high cholesterol include family history and the modifiable lifestyle choices of diet and exercise.
- Having high cholesterol does not usually produce any symptoms.
- If lifestyle changes are unsuccessful or cholesterol levels are very high, a doctor may prescribe a lipid-lowering drug, such as a statin.
About Cholesterol Testing And The Lipid Panel:
This kind of test is one of routine based on a simple blood sample from you. The health professional will take a sample of your blood that will further be analyzed in a laboratory and in about 24 hours the results will be ready.
However, there are some rules you need to respect to make sure that the test will be properly done. The usual cholesterol tests require a period of 9-12 hours of fasting before the blood is drawn and avoidance of strenuous effort before the test.
If you are consuming food or beverages then the test will only provide total cholesterol and HDL cholesterol values because the LDL and triglyceride levels are influenced by the food recently consumed.
You should also inform your doctor about any medical conditions you have, any medical treatment you are following or other details that you consider relevant and that could interfere with the results of the test.

Drug Therapies To Treat High Cholesterol
When lifestyle changes alone cannot bring down high cholesterol, doctors may recommend medications. The reports that the following drugs and supplements can help:
- Statins: These drugs keep the liver from producing cholesterol.
- Bile acid sequestrants: These drugs reduce the amount of fat that the body absorbs from food.
- Cholesterol absorption inhibitors: These drugs lower levels of fats called triglycerides in the blood and reduce the amount of cholesterol absorbed from food.
- Some vitamins and supplements: These, such as niacin, stop the liver from removing HDL and lower levels of triglycerides.
- Omega-3 fatty acids: These raise HDL levels and lower triglyceride levels.
Increase The Amount Of Fiber In Your Diet
Most of us do not get enough fiber in our diet. The recommended amount is 25-35 grams of dietary fiber per day. Dietary fiber is a type of carbohydrate that the body cannot digest. As fiber passes through the body, it affects the way the body digests foods and absorbs nutrients. Fiber can help reduce your LDL cholesterol level. A fiber-rich diet can also help control blood sugar, promote regularity, prevent gastrointestinal disease and help you manage your weight.
There are two types of dietary fiber: soluble and insoluble. To receive the greatest health benefit, eat a wide variety of all high-fiber foods. Refined foods, like white bread, white pasta and enriched cereals are low in fiber. The refining process strips the outer coat from the grain, which reduces the amount of fiber thats left.
The best sources of fiber are whole grains, fruits, vegetables and legumes .

What Are Unsaturated Fats
Unsaturated fats are considered the healthiest fats because they improve cholesterol, help reduce inflammation , and help decrease the overall risk of developing heart disease. The main source of unsaturated fats are plant-based foods. These fats are usually liquid at room temperature. There are two types of unsaturated fat: monounsaturated and polyunsaturated.
Monounsaturated fats are considered one of the healthiest sources of fat in the diet. These fats should make up most of your daily fat intake. Good sources of monounsaturated fats include:
- Olive, canola and peanut oils.
- Most nuts, nut oils and nut butters .
Good sources of Polyunsaturated Fats include:
- Safflower oil.
- Flax oil and flax seeds.
- Sunflower oil.
- Canola Oil.
What Is Insoluble Fiber
Insoluble fiber is generally referred to as “roughage.” Insoluble fiber promotes regularity, adds bulk and softness to stools, helps with weight regulation and helps prevent many gastrointestinal disorders. Good sources on insoluble fiber include:
- Wheat bran and whole wheat or grain bread/bread products, pasta, cereal and crackers.
- Vegetables.

No Apparent Danger Of Very Low Ldl Cholesterol
LDL is a key component of many hormones and all cell membranes, which allow cells to communicate with each other. Earlier studies had raised concerns that lowering LDL too far might interfere with normal cellular functions, especially in organs that have higher lipid concentrations, such as the brain and reproductive organs. And there have been reports of a slightly increased risk of osteoporosis and brain bleeding in patients treated with high doses of statin medications.
Well-known side effects in people who use statin medications include muscle aches and a slightly increased risk of diabetes, especially when high doses of medication are used. Whether these risks are due to the statin medications themselves or the lowering of LDL is not entirely clear.
However, people with rare inherited disorders in which LDL levels are extremely low from birth appear to have normal fertility and no major organ dysfunction. Therefore, an extremely low LDL by itself does not appear to be dangerous in these unusual cases.
What Is A Dangerous Cholesterol Level
Cholesterol is a waxy, fat-like substance found in your blood, according to the American Heart Association . It gets a bad rap, but your body actually needs cholesterol to function properly. The key, as with most things, is striking a healthy balance.
