Low Cholesterol Diet
Fat is a major energy source for the body. However, it is not the body's only source of energy. Too much fat in the diet can be harmful. It is especially bad for the circulatory system, because it raises blood cholesterol levels that can contribute to heart attack or stroke. This diet is designed to reduce fat and cholesterol blood levels. The diet goals are:
- decrease total dietary fat, especially saturated and trans fat, also known as hydrogenated fat
- decrease dietary cholesterol
- limit sodium intake
- increase intake of fiber, especially complex carbohydrates and prebiotic fibers
- decrease calories, if needed, to reach a healthy body weight
Cholesterol in the Diet
The heart pumps blood through blood vessels called arteries. This blood carries vital oxygen and nutrients needed by tissues and organs throughout the body. The heart itself is supplied with blood vessels called coronary arteries. When cholesterol levels rise above normal limits and stay high, some cholesterol is left behind in the arteries. Over the years, waxy cholesterol plaques build up on the artery walls, and so reduce or block blood flow. When blood flow to the brain is blocked, a stroke occurs. When plaque blocks a coronary artery, angina or a heart attack may be the outcome.
Cholesterol in the body comes from two sources. Most cholesterol is made by the liver from various nutrients and especially from ingested fats. The liver makes just about all the cholesterol the body will ever need. Since all animals can make their own cholesterol, some cholesterol in the human body comes directly from eating animal foods. These foods include meats, poultry, egg yolks, organ meats, whole milk and milk products. This cholesterol is absorbed through the intestines and added to what the liver makes. It is also known that a diet high in saturated fat increases cholesterol production in the body. Therefore, reducing dietary cholesterol and fats helps to keep blood cholesterol levels within a healthy range. Most important of all is to significantly reduce the amount of animal meat, meat products and trans fat in the diet.
Fats in the Diet
Dietary fats can be saturated (bad) or unsaturated (good). An easy way to remember the difference is that saturated fats solidify or remain solid at room temperature. Unsaturated fats do not; they are soft or liquid at room temperature. To reduce blood cholesterol levels, it is especially important to limit saturated fats. Saturated fats are found mainly in meats and dairy products made with whole milk.
Unsaturated fats (polyunsaturated and monounsaturated) are found mostly in plants, and are less likely to raise blood cholesterol levels. In fact, monounsaturated fats such as olive, peanut, or canola oils may even help to lower blood cholesterol. There are a few vegetable fats such as coconut oil, palm oil, and cocoa butter (found in chocolate) that act like saturated fats in the body, so they should be avoided.
In the past, food manufacturers "hydrogenated" vegetable oils to prevent rancidity and increase shelf life. These chemically derived oils are commonly known as trans fats. They act in the body exactly as do the saturated animal fats, raising cholesterol and, especially, the bad LDL cholesterol. These trans fats should be avoided. Always read the ingredients label on foods. For example, coconut and palm oils are bad, as are saturated fats, and should be avoided. Mono- and polyunsaturated oils like olive oil, canola and cottonseed are good.
Butter and Spreads
Gut Bacteria and Prebiotic Fibers
Prebiotics in your diet or in a supplement naturally restore digestive balance and health. Learn more . . .
Fiber in the Diet
There are two main types of fiber - insoluble and soluble. All fiber moves through the gut into the colon unchanged. Within the colon, insoluble fiber, as present in wheat and corn, is not fermented by colon bacteria but rather clings to water and helps provide a bulky stool. Soluble fiber, on the other hand, is fermented by the good colon bacteria and, in so doing, helps to lower cholesterol and especially triglyceride, another nasty fat that is of concern to some heart patients.
The supplement psyllium and also oats are especially important in lowering cholesterol. Both of these fibers, along with the healthy prebiotic fibers, are present in Prebiotin-Heart Health™.
Fresh foods purchased at a local market are almost always the best. However, we usually can't avoid getting some packaged foods. Food labels provide a wealth of information. Read them. You will find:
- Serving size - Many manufacturers will have an unrealistically low serving size simply so they can artificially lower the amounts listed in the Nutrition Fact portion of the label. Be sure the serving size conforms to what you eat at a sitting.
- Nutrition Facts - Here is where you get information on calories, cholesterol, fat, fiber and sodium. It is best to avoid foods with an unrealistic low serving size and high fat content.
- Ingredients - In the very smallest print, you will find all the ingredients in the product. They have to be placed in the order of the highest to lowest amounts within the food. Packaged foods with perhaps 8 or more ingredients, many of which you do not recognize, may be packed with calories and fat in hidden ways. Be wary! An example of how one can be misled on labels is to see that there are 0 grams of trans fat in a product. The FDA allows the manufacturer to say this even when there is 0.5 gm of trans fat per serving. So, you must read the ingredients part of the label.
Packaged foods, fast food restaurants, and the ready availability of sugar and calorie laden liquids are in front of us at all times. To the extent you can, restrict your eating to those foods you and your companion have control over. It may not be as fast as packaged food and fast food restaurants, but the enjoyment of food preparation and taking control of your eating has its own rewards.
Sugar and High Fructose Corn Syrup
Nature never intended us to have so much sugar. Honey, molasses and sweet fruits were natural flavors. Now, enormous amounts of simple table sugars (sucrose) are put into many foods. The body processes these as calories, and the weight and cholesterol may both go up.
As bad as sugar has been, high fructose corn syrup (HFCS) may be worse, as our bodies were never designed to receive such large amounts of fructose, a natural fruit sugar. Again, calories, weight and cholesterol may go up. So, the advice is to limit sugar and HFCS. Together, excess sugar and HFCS may cause weight gain, metabolic syndrome and accompanying atherosclerosis. Read the labels.
The meat industry and farming has been one of the enormously successful businesses in the Western World. Not too many generations ago, meat on the dinner table was a rarity. Then, families in the US raised their own meat on farms. Finally, the meat industry, helped enormously by subsidized corn-based feed, was able to spread cuts of meat in front of us at very affordable prices. The answer for a cholesterol/weight concerned person is to cut back drastically on the frequency and the amount of meat. Remember, marbling in meat is saturated fat, and prepared and processed meats such as bacon, sausage, scrapple, bologna, etc., are very high in saturated fat. So, one should restrict the frequency of meats, where possible, trim away the fat, and select those meats with the lowest amounts of saturated fats.
Fish and Fish Oil
It is now well known that fish, and especially certain types of fish such as salmon, albacore tuna, lake trout, herring and mackerel, contain very healthy types of oils that actually lower cholesterol. The oils in these and other fish are particularly healthy for the heart patient. Fish should be consumed 3-4 times a week, preferably baked or broiled rather than sauteed or deep-fried with extra fats.
Fish oil capsules are a concentrated form of this oil and many cardiologists now recommend them for heart patients.
Complex carbohydrates come from natural plants and not from processed foods. Sugar and high fructose corn syrup are simple carbohydrates and, to the extent possible, should be restricted. In particular, one should select whole wheat or grain foods. The FDA has strict requirements when this phrase is used. Almost every other term such as multigrain, 7 grain, grain plus, etc., can mean almost anything the manufacturer wants. Read the labels. In particular, avoid foods where the word "enriched" is used. What this means is that the flour has been refined down to white flour (no fiber and few complex carbohydrates) and it has been "enriched" by adding a few vitamins. It is a bit of a deceit.
Sodium and Salt
Excess sodium is quite often linked closely to high cholesterol and heart disease. It certainly is directly related to high blood pressure. Low sodium foods are now widely available. There are many other spices that can be used other than table salt. Again, read the labels and especially the salt/sodium content on the nutrition part of the label.
In restaurants, ask the server how items are prepared. It should be remembered that tubs of butter sit around the kitchen simply because adding butter increases flavor and is used copiously by most chefs. Tell your server you are on a low saturated fat, low butter diet.
