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.
Trans fat. Small amounts of naturally occurring trans fats can be found in meat and dairy products but it’s artificial trans fats that are considered dangerous. This is the worst type of fat since it not only raises bad LDL cholesterol but also lowers good HDL levels. Artificial trans fats can also create inflammation, which is linked to heart disease, stroke, and other chronic conditions and contributes to insulin resistance, which increases your risk of developing Type 2 diabetes.
Eating foods rich in trans fats increases the amount of harmful LDL cholesterol in the bloodstream and reduces the amount of beneficial HDL cholesterol. Trans fats create inflammation, which is linked to heart disease, stroke, diabetes, and other chronic conditions. They contribute to insulin resistance, which increases the risk of developing type 2 diabetes. Even small amounts of trans fats can harm health: for every 2% of calories from trans fat consumed daily, the risk of heart disease rises by 23%.
This little wonder food checks all the boxes. It’s an inexpensive food that’s packed with protein and a full amino acid profile. And contrary to decades of popular belief, eggs also don’t raise bad cholesterol levels. In fact, consuming eggs can actually lower cholesterol while improving heart health. (22) The choline found in eggs is also helpful at keeping our brains in tip-top shape. (23)
Meanwhile, the official unsaturated fat definition encompasses any type of fatty acid that contains at least one double bond within the chain. These fats are further classified as either a monounsaturated fat or polyunsaturated fat based on the number of double bonds they contain. Unsaturated fats can include foods like vegetable oils, nuts, seeds and fish.
Nuts like pecans, pistachios, cashews, and almonds also pack a lot of healthy fats. Almonds are the richest in vitamin E, and pistachios have lutein and zeaxanthin, carotenoids important for eye health. All you need to eat is a 1/4 cup serving per day to reap the benefits. Some varieties are fattier than others, like cashews and macademia nuts, so you need to pay closer attention to serving sizes. (Nuts have, on average, 45 grams of fat per cup.) Nutritionists love pistachios because the fact that you have to shell them helps you eat slower and naturally control portion size. The peanut (technically a legume) contains monounsaturated fats but all of its polyunsaturated fats are omega-6s, which evidence suggests may not do us any favors.
Meanwhile, the Indian version of butter is quickly becoming a favorite across the globe. Ghee, or clarified butter, is simmered to bring out butter’s naturally nutty flavor, leaving it with a high smoke point that makes it ideal for cooking at high temperatures. Ghee benefits include being loaded in fat-soluble vitamins A and E. These types of vitamins are best absorbed by your body when they’re in a high-fat substance and then stored in your gastrointestinal tract, keeping your metabolism and digestion on track. It’s also lactose- and casein-free, which makes it a fantastic alternative to butter if you suffer from lactose sensitivity or intolerance.
