Good Fats vs. Bad Fats
Here is why they are heart healthy and how to get them. Unsaturated Fats - Unlike saturated fats, monounsaturated and polyunsaturated fats are made up of fatty acids that have a chemical structure slightly different than saturated fats.
Saturated fats are fully saturated with hydrogen, while the unsaturated fats have at least one double bond between carbon molecules. Trans fat are a unique type of fat. Trans fats are unsaturated fats but the shape of the fat is similar to a saturated fat. All foods with fat have both saturated and unsaturated fats.
The proportions of the two types of fats vary considerably, though. Foods high in saturated fats will be solid at room temperature. Think of beef fat and other meat fats, butter and coconut oil. Also high in saturated fat are cheese and full fat milk.
Foods high in the unsaturated fatty acids, on the other hand, will be more liquid at room temperature. Think of vegetables oils and nut oils. For a heart healthy diet, choose more foods rich in unsaturated fats and fewer foods rich in saturated fat.
Omega-3 Fatty Acids- Omega-3 fatty acids are a special type of polyunsaturated fatty acid. The presence of a specific chemical bond identifies them as omega-3 fatty acids. Eating higher levels of omega-3 fatty acids may lower rates of heart disease. Omega-3 fats may improve cardiovascular health by several means including improving blood circulation and improving levels of blood lipids.
Other health benefits may also be linked to omega-3s such as improved immune function. Omega-3 fatty acids are found in fish and fish oil with the best fish sources being oily fish like salmon, herring, and mackerel.
Other sources of omega-3 fats are flaxseed and flaxseed oil, meat from grass-fed animals (as opposed to grain-fed animals) and certain nuts including walnuts. Plant Oils - Most oils from vegetables, nuts and seeds contain heart healthy fats like monounsaturated, polyunsaturated and omega-3 fatty acids. Plus, they are generally low in saturated fat and contain no trans fat.
Some oils are healthier than others, though. One thing to look at is what proportion of the vegetable oil is unsaturated fats. Oils with low levels of saturated fat are canola, corn, olive, safflower, sesame, soybean and sunflower oils. Although not commonly used as cooking oils, palm oil and coconut oil are plant oils with high levels of saturated fat.
Of course, in addition to eating right, it’s important to have your spine checked regularly for subluxations. If you haven’t been in for an adjustment recently, make an appointment today!
