What are healthy fats?
Healthy fats are essential dietary fats that provide numerous health benefits. They include monounsaturated fats, found in foods like olive oil, avocados, and nuts, and polyunsaturated fats, which include omega-3 and omega-6 fatty acids found in fatty fish, flaxseeds, and walnuts. These fats are vital for maintaining heart health, supporting brain function, and regulating inflammation but the body can't make them itself - hence why we need to obtain these exclusively from diet. In contrast to trans fats and excessive saturated fats, healthy fats can help lower 'bad' LDL cholesterol levels and reduce the risk of chronic diseases. Omega-3s, in particular, are crucial for brain development and function, while omega-6s play a role in immune function and inflammation regulation. Including these fats in your diet supports overall wellness and plays a key role in cell structure, hormone production, and nutrient absorption. However, it's worth noting that the ratio of omega 3:6 is important and often a typical Western diet is richer in omega 6 and lower in omega 3. So, focusing on increasing omega 3 intake is best.
Why are healthy fats good for us?
Healthy fats offer a range of benefits that are vital for bodily functions. They support cardiovascular health by lowering LDL (bad) cholesterol and increasing HDL (good) cholesterol, which helps reduce the risk of heart disease. Omega-3 fatty acids, a type of polyunsaturated fat, are known for their anti-inflammatory properties and brain health benefits. Healthy fats also support hormone production and nutrient absorption, especially fat-soluble vitamins like A, D, E, and K. Including these fats in your diet provides sustained energy, aids in mood regulation, and helps maintain healthy skin and hair. Additionally, healthy fats help protect organs, insulate the body, and support immune function, making them a vital part of a balanced diet.
Can you have too many healthy fats?
While healthy fats are beneficial, consuming too much of them can lead to an imbalance in your diet. Fats are calorie-dense, providing 9 calories per gram compared to 4 calories per gram of protein or carbohydrates. Overeating fats, even healthy ones, can contribute to weight gain, especially if your calorie intake exceeds what your body needs. Also, the omega 3:6 ratio is important. Having too much omega 6 versus omega 3 can drive systemic inflammation. The key is moderation, and it’s important to ensure your diet includes a balance of fats, proteins, and carbohydrates. Also, focusing on increasing omega 3 versus omega 6 can help support a balanced ratio. Increasing oily fish to 2-3 portions per week and consuming nuts like walnuts and seeds such as chia and flax daily can help support omega 3:6 balance.
It's worth noting that some people may also experience digestive issues if they suddenly increase fat intake without gradually adjusting their diet.
What happens if you have too many healthy fats?
Consuming excessive amounts of healthy fats can lead to unintended health consequences, such as weight gain due to the high caloric content of fats. This can increase the risk of obesity-related conditions, such as heart disease, diabetes, and certain cancers. Additionally, overconsumption of omega-6 fats, which are found in many plant oils and processed foods, without balancing with enough omega-3s, can lead to increased inflammation in the body. This may exacerbate conditions like arthritis, cardiovascular disease, and inflammatory disorders such as endometriosis. Digestive issues, such as diarrhea, bloating, or indigestion, may also occur when fat intake is suddenly increased, where digestive enzymes just can't keep up. Overall, while healthy fats are essential, consuming them in excess can disrupt your body’s balance, leading to potential health concerns.
