Are you confused about fats and oils in your diet?
There a common diet trend that eliminates fats for weight loss and health. Eliminating dietary fats is not good for the body.
Dietary fats help with many basic functions in the body:
- Protect your organs
- Help keep your body warm.
- Fats help your body absorb fat-solubleť vitamins A, D, E and K and stores them in the liver and in fatty tissues for future use.
- Cholesterol, which is created by fat, produces important hormones like estrogen and testosterone.
Yes, we need fat but not as much as we usually eat.
There are three main dietary fats. Each fat has different chemical structures and physical properties.
- Unsaturated Fats (called the good fats) can improve blood cholesterol levels, ease inflammation and stabilize heart rhythms. They are liquids at room temperature.
Two types of unsaturated fats:
- Monounsaturated Fats are found in high concentrations in olive oil, peanut oil, avocados, almonds, hazelnuts, pecans, pumpkin seeds and sesame seeds.
- Polyunsaturated Fats are found in high concentrations in sunflower, corn, soybean, flaxseed oils, walnuts, flax seeds and fish. Omega-3 fats are one important type of polyunsaturated fat. The body can’t produce these, so they must come from food.
Most of us don’t get enough of these healthy unsaturated fats. The traditional Greek diet gets up to 30 percent of its calories from monounsaturated fats, mostly from olive oil.
- Trans Fat raises bad cholesterol and increases the risk of heart disease. Even worse, it lowers good cholesterol! The American Heart Association recommends limiting your trans fat daily consumption to less than 1 percent.
Scientists have now established that trans fats found in many fast foods, bakery products and margarines increase the risk of cardiovascular disease through inflammatory processes.
- Saturated Fats, according to old research, raises blood cholesterol levels. High blood cholesterol is a risk factor for heart disease. Foods containing saturated fat include: Lard, pork, regular ground beef, bologna, hot dogs, sausage, bacon, full-fat cheese, ice cream, whole milk, sour cream, butter, palm oil, coconut oil, chicken and turkey skin.
The Cholesterol Myth
Cholesterol is a natural part of our body; we have between 1,000 and 2,000 milligrams of cholesterol in our body at any time depending on our body size. Three quarters of it is produced our body’s liver, and one quarter comes from our diet, much of that is unable to be absorbed by our body. We have a sophisticated control system that controls the amount of cholesterol in the blood by controlling internal production. When there is not enough cholesterol coming in, your body creates more. When there is too much coming in our body makes less.
Saturated fats like butter and coconut oil have a bad public image. Research studies in both animals and humans, done more than half a century ago, stated that saturated fats raise blood cholesterol and cause heart disease. Coconut oil research done in the past used hydrogenated coconut oil, which is a trans fat. These studies were also only conducted for a few weeks, rather than long term. There are more recent studies of a higher quality that show different results.
- Data from 21 studies with nearly 348,000 adults, found no difference in the risks of heart disease and stroke between people with the lowest and highest intakes of saturated fat.
Unsaturated Oil is Not as Good as We Thought!
Unsaturated oils in cooked foods become rancid within a few hours, even in the refrigerator. Once fresh unsaturated fats are inside the body, they oxidize (turn rancid). Coconut oil does not go rancid even after one year at room temperature. Even ghee, made from butter, will last for 3 to 6 months at room temperature. Most of the saturated fat in coconut oil is easy to digest and converts into quick energy so people are less likely to become obese, as the fat is not stored.
To quote Dr. Mary Enig: “The research over four decades concerning coconut oil in the diet and heart disease is quite clear: coconut oil has been shown to be beneficial.” Coconut oil has been used as cooking oil for thousands of years.
Stay Away From Trans Fats!
Remember when they told us to eat margarine instead of butter? It turns out that most margarine is filled with trans fats and butter is fine when used in moderation.
The real problem-fats in our diets are the trans fats also known as hydrogenated oils; they are found in most processed food, including margarine, potato chips, baked goods etc. They are toxic, blocking absorption of essential fatty acids and raising blood cholesterol.
All Fat Have Calories!
Also, whether it is olive oil, ghee, butter or coconut oil … they are all 100 percent fat! No matter how good the oil sounds…..remember that it is still a fat, with 120 calories per tablespoon. Consuming a high fat diet may lead to becoming overweight and that is not healthy!
