Latest Discoveries in Nutritional Ecology: Effects of polyunsaturated fats on health
The field of nutrition epidemiology, in recent years has focused more on the role that different types of fats have played in the health of people. In this article, we will explore the latest discoveries regarding the health effects of polyunsaturated dietary fats. You can expect as readers to learn more about the benefits of polyunsaturated fats and how you can incorporate them in your diet.
Polyunsaturated fats are important
These fats are required by your body for its normal functions, but you cannot produce them. You must therefore get them through food. These fats have been shown to be beneficial for the heart in recent research . A 2020 study , published in the Journal of the American Heart Association (JHA), found that replacing saturated fats with polyunsaturated ones reduced the risk of cardiovascular diseases by as much as 30% .
Not all polyunsaturated fatty acids are the same. Omega-3 and omega-6 fats are the two most common types. It is important to maintain a balance between both. Omega-6 fatty acid is beneficial when consumed in moderation. However, a diet high in omega-6 compared to omega-3 - which is typical in Western countries - has been linked to an increased risk of chronic illnesses, such as heart disease and even cancer.
Start Here: Incorporating Polyunsaturated Fatty Acids in Your Diet
In order to reap the benefits of polyunsaturated fatty acids, you should include foods high in them into your diet. You also need to maintain a healthy balance between Omega-3 and Omega-6 fatty acids. Omega-3-rich foods include salmon, mackerel and flaxseeds. Chia seeds and walnuts are also high in this fatty acid. Vegetable oils, seeds, and nuts are foods high in Omega-6.
The American Heart Association suggests that the emphasis should be placed on eating foods rich in nutrients and minimally processed, polyunsaturated fatty acids, instead of adding them to a high-processed food diet.
Latest Discoveries: Polyunsaturated fats and their effects on health
- Journal of Nutrition published a study that found consuming more polyunsaturated fatty acids was linked to a reduced risk of developing type 2 diabetes.
- In 2020, a study published in The British Journal of Nutrition suggested that eating more omega-3 fats could reduce depression symptoms.
- In a 2018 PLOS Medicine study , it was found that substituting saturated fats for polyunsaturated ones reduced coronary heart disease risk.
- A study published in 2020 in the Journal of Clinical Endocrinology & Metabolism suggests that consuming more polyunsaturated fatty acids may reduce the risk of childhood asthma.
- In 2019, research published in The American Journal of Clinical Nutrition found that pregnant women who consume more omega-3 fatty acid may have a lower risk of preterm birth.
Other Tips
It's important to keep in mind that the overall pattern of your diet matters. A balanced diet rich in nutrients, including fruits, vegetables and whole grains as well as lean protein, can improve health.
Regular exercise, maintaining an ideal weight, not smoking, and limiting your alcohol consumption are all important factors for overall wellbeing. The lifestyle factors work in synergy with healthy eating habits to maximize the health benefits of polyunsaturated fatty acids.
Conclusion
Recent discoveries in nutrition epidemiology shed light on polyunsaturated fatty acids' potential health benefits, from decreasing the risk of cardiovascular disease, type 2 diabetes, and depression, to improving the symptoms and preventing preterm birth. It's important to consume a diet rich in nutrients and low-processed foods, while maintaining a balance of omega-3 and Omega-6 fatty acid intake. Continued research is sure to provide more insight into these important fats and their role in health as we progress.
