Fat is an energy source and plays an essential role in body temperature regulation, hormone production, cell signaling and nutrient absorption. A gram of fat provides nine calories.
Dietary fats fall into two broad categories: saturated and unsaturated. Saturated fats, found primarily in meats and dairy products, remain solid at room temperature while unsaturated ones, liquid at room temperature, can be found in vegetable oils, nuts and fish products.
Saturated Fat
Saturated fats are solid at room temperature and typically found in animal products such as meat, whole milk, cheese and coconut oil; they’re also present in some processed foods such as baked goods. Health professionals long viewed saturated fats as “bad”, as they raise blood cholesterol levels which can contribute to heart disease; however, recent research has disproved these beliefs; the Dietary Guidelines for Americans suggest no more than 10% of your calories come from saturated fats (or 22 grams on a 2,000-calorie diet).
Saturates can be defined chemically as having all single bonds between carbon molecules, while unsaturated fats contain double bonds within their fatty acid chains, distinguishing between saturated and unsaturated varieties. This difference in structure explains why unsaturated fats behave differently: all dietary fats consist of glycerol backbones with attached fatty acid chains connected by either single bonds, double bonds or none at all – this results in their distinctive behavior; finally they’re wrapped around the backbone to form what’s known as triglycerides; according to their chemical makeup they fall into either saturated, monounsaturated and polyunsaturation categories depending on how they behave chemistry-
Saturated fats play an integral part in our health because of their capacity to increase levels of LDL-cholesterol in our blood, which can clog arteries and block blood flow to vital organs – increasing your risk for cardiovascular disease. Saturated fats may also promote weight gain by speeding up metabolism and encouraging excess energy storage as body fat.
Studies demonstrate how saturated fat can exacerbate inflammation by altering the activity of certain genes within macrophages – your body’s first line of defense against infections and other forms of inflammation. Genes activated by saturated fat are connected with producing pro-inflammatory cytokines which may result in symptoms such as rheumatoid arthritis.
Reducing saturated fat intake may reduce protective HDL-cholesterol, which in turn lowers your heart disease risk. Replacing saturated fats with unsaturated ones like olive, canola or avocado oils will help improve cardiovascular health – while eliminating trans fats will strengthen it even further.
Recent studies suggest that eating a Mediterranean-style diet, which is rich in unsaturated fats and low in saturated and trans fats, may lower one’s risk for heart disease. Focus on including healthy fats from olive, canola and avocado oils, nuts and seeds in your diet while cutting back on unhealthy ones, along with plenty of fiber to ensure an energy boost, improved vitamin absorption and weight maintenance. This will lead to optimal performance. By eliminating high-calorie, low-nutrient foods and increasing vegetables and fruits in your diet, the Mediterranean Diet can be utilized to achieve this goal. Studies have linked it with lower incidences of heart disease as well as reduced risks of chronic conditions like cancer and obesity; its balanced approach can be further customized by including more plant proteins like legumes and whole grains into it.
