But even as important is their ability to reduce the negative impact of yet another essential type of fatty acid known as omega-6s. Found in foods such as eggs, poultry, cereals, vegetable oils, baked goods, and margarine, omega-6s are also considered essential. They support skin health, lower cholesterol, and help make our blood "sticky" so it is able to clot. But when omega-6s aren't balanced with sufficient amounts of omega-3s, problems can ensue.
Eggs are an inexpensive and easy source of protein. People often think egg whites are a healthier option than whole eggs because they contain less fat, but while it's true that the egg yolk contains some fat, it's also packed with important nutrients. One whole egg contains 5 grams of fat, but only 1.5 grams are saturated. Whole eggs are also a good source of choline (one egg yolk has about 300 micrograms), an important B vitamin that helps regulate the brain, nervous system, and cardiovascular system. As for the cholesterol? The latest nutrition research has found that eating cholesterol doesn't raise our blood cholesterol. In fact, research has linked moderate egg consumption to improved heart health.
Hi, and Thank you for a very interesting website. I read the newsletters with curiousity and I learn new things. I am a Norwegian woman who started with LCHF diet/ keto three months ago. My motivation was serious healthchallenges with IBS, which became increasingly difficult after an gut infection last summer. My gut is much better! Not “perfect”, but the difference from three months ago is huge. My energy level is also coming back to normal, and even better! I have a question about canola oil. I am confused. I thought it was healthy, and that the balance between omega 3 and 6 was good. Canola oil is a preferred oil, together with olive oil, coconut oil and butter, on dietdoctor.com and other lowcarb-websites and books. So I wonder, why is it in your opinion on the “not to eat” list? Is it something that happens with it during the process of production? Or? Kind Regards, Mona Sommer
Cholesterol is a waxy substance that is found only in animal foods. Unlike fatty acids, it doesn’t provide energy. However, your body needs it in order to produce steroid hormones, vitamin D, and bile acids that help digest fat. All of your cells make cholesterol; in fact, most of the cholesterol in your blood comes from your body rather than the food you eat. Dietary cholesterol does not raise blood cholesterol levels much, if at all, nor does it increase heart disease risk.
For decades, doctors, nutritionists, and health authorities have told us that a diet high in saturated fats raises blood cholesterol and increases the risk of heart disease and stroke. However, recent studies have made headlines by casting doubt on those claims, concluding that people who eat lots of saturated fat do not experience more cardiovascular disease than those who eat less.
Many people also wonder: is cheese bad for you? Like other dairy products, not all cheese is created equal, but it can be part of a nutritious, well-rounded diet. Ideally, look for varieties that are raw, minimally processed and derived from grass-fed animals. Feta, goat, ricotta and cottage cheese are a few of the top healthiest cheese options available.
Salads are a healthy-eating staple. But not only can they sometimes leave us hungry, but they can also just become flat-out boring after awhile. Ingredients packed with healthy fats are an easy solution for both of those common issues. Healthy fats include unsaturated fats, monounsaturated fats, polyunsaturated fats, and Omega-3 fatty acids. Including healthy fats that are rich in protein and fiber to your salads is a great way to get a nutritional boost and feel full at the same time. Healthy fats come in a variety of food sources that are all very easy to use as salad add-ins. We talked to Beth Warren, registered dietitian and Author of Secrets of a Kosher Girl to learn her top picks for salad add-ins full of healthy fats.
Of the three macronutrients, carbohydrates are our body’s preferred energy source because they are easier and quicker for our bodies to digest and use for energy. On the other hand, fat takes a different route before we can use it as energy because it is insoluble in our blood. Think of fat as being a reserve or our long-term source of energy that sticks around the longest. On the technical side, which we’re about to get very technical: fat is three fatty acids + a glycerol molecule, or a triglyceride (tri- as in three and glyceride).
So you might assume that fat is to blame for the obesity epidemic now plaguing our nation. Actually, fat is only part of the problem. Obesity is much more complicated than just overeating a single nutrient. Eating more calories -- from fats, carbohydrates, protein, and alcohol -- than you burn off leads to weight gain. Simply put, people who get little physical activity and eat a diet high in calories are going to gain weight. Genetics, age, sex, and lifestyle also weigh into the weight-gain formula.
Healthy fats have numerous benefits for your body when included as part of a healthy balanced diet. A diet which includes moderate to high amounts of monounsaturated fats can be useful in weight loss, as long as you don’t eat more calories than you are burning. A large study which combined the results of twenty four other studies found that participants who followed a high-monounsaturated fat diet had more effective weight loss than those who followed high-carbohydrate diets (10).
Monounsaturated fats are typically liquid at room temperature but solidify if refrigerated. These heart-healthy fats are typically a good source of the antioxidant vitamin E, a nutrient often lacking in American diets. They can be found in olives; avocados; hazelnuts; almonds; Brazil nuts; cashews; sesame seeds; pumpkin seeds; and olive, canola, and peanut oils.
People often turn to fat free options when trying to lose weight but these foods are very poor choices nutritionally. Fat free foods are more often than not loaded with sugar and additives that act as toxins to the body. Your body is able to recognize the compounds in healthy fats and digest them as a source of fuel. This boost in energy is good for kicking your metabolism into gear which, you guessed it, is good for your weight loss.
If you’re wondering about fat and its place in your diet, you’re not alone. Each year the International Food Information Council Foundation conducts a nationwide survey of Americans of all ages and backgrounds. When the results were released earlier this year, fat was found to be one of the biggest topics of nutritional confusion. Research around the importance of fats in the diet continues to grow and results repeatedly underscore the importance of a healthy meal plan that focuses on moderation vs. a restrictive diet. When it comes to healthy fats, here’s what you need to know.
Most nuts and seeds are good healthy-fat choices, but almonds and walnuts are at the top of many experts’ lists as a great part of a heart-healthy diet to lower high cholesterol. “Almonds and walnuts are quick, delicious, and easy for a mid-morning or mid-day snack,” says Maria Haisley, RD, a clinical dietitian at Elkhart General Hospital in Indiana. “Make your own trail mix using your favorite ingredients or simply add to salads. Try using ground almonds as a coating on baked chicken or fish.” This chicken fingers recipe is a delicious way to do just that.
Several studies explore and show the this type of saturated fat in coconut does not negatively affect cholesterol levels nor overall heart health like we were once told. Some studies have shown coconut oil moderately increases metabolic rate, which is often a “selling” point that it helps boost your metabolism and contribute to fat loss or weight control. I’ll let these studies here, here, and here tell you what we do know.
Consuming monounsaturated fatty acids may protect you from heart disease by lowering LDL and total cholesterol, improve the function of blood vessels, help prevent depression, improve body composition, and improve insulin sensitivity and blood sugar control (10,11). Monounsaturated fats have even been shown to reduce cancer risk (12). Oils rich in monounsaturated fats also contain the antioxidant vitamin E which has many health benefits.
When in the correct balance with omega-3 fats, omega-6 fats are healing fats. Like omega-3 fatty acids, omega-6 fatty acids are polyunsaturated fats. There are healthy and unhealthy sources of omega-6 fats. Healthy sources include sunflower seeds, wheat germ, sesame seeds, and walnuts. When eaten in the ideal ratio with omega-3 fats (between 4:1 and 1:1), these omega-6 fats promote health.
