What are healthy fats and their role in our diet? Let’s explore the benefits and sources in this brief overview.
What Are Healthy Fats?
They are an essential components of a balanced diet, crucial for various bodily functions such as energy production, cell maintenance, hormone regulation, and nutrient absorption.
Amid conflicting dietary advice over the years, it’s evident that not all fats are equal. One standout among the array of fats is omega-3, which is often under consumed.
Omega-3s are a type of polyunsaturated fat classified as essential nutrients, meaning our bodies cannot produce them naturally.
Sadly, a study based on the National Health and Nutrition Examination Survey reveals that a significant portion of both adults (68%) and children (over 95%) fall short of recommended omega-3 intake levels.
These vital fats are primarily found in fish, but they also exist in dark leafy greens, flaxseeds, hempseeds, and walnuts. In contrast, omega-6 fatty acids, another type of polyunsaturated fat, are readily available in cooking oils, nut butters, and eggs.
Dietary guidelines suggest that fat should constitute 20-35% of daily caloric intake, with less than 10% coming from saturated fats. It’s imperative to steer clear of trans fats, notorious for increasing the risk of heart disease, stroke, and type 2 diabetes.
There are four major types of healthy fats, each with its own characteristics and effects:
- Trans fat: Typically found in partially hydrogenated oils, linked to heart disease, stroke, and type 2 diabetes.
- Saturated fat: Predominantly present in solid forms such as meat, butter, and coconut oil.
- Monounsaturated fat: Known for promoting heart health by increasing “good” cholesterol levels.
- Polyunsaturated fat: Contains valuable omega-3 and omega-6 fatty acids.
Omega-3 fatty acids offer a plethora of health benefits, including supporting heart health, reducing cancer, cognitive, and eye disease risks, and even potentially alleviating depression due to their anti-inflammatory properties. Additionally, a lack of omega-3s may manifest as dry skin and brittle hair.
The Dietary Guidelines for Americans recommend consuming at least 8 ounces of seafood weekly for adults on a 2,000-calorie diet. Pregnant or breastfeeding individuals are advised to consume 8 to 12 ounces of low-mercury fish weekly for fetal development benefits. A single serving is approximately 4 ounces of fish.
While fish like salmon and tuna are well-known sources of omega-3s, exploring options like herring, sardines, and anchovies can be rewarding.
For those averse to fish, leafy vegetables, vegetable oils, nuts, flax seeds, and flaxseed oil can provide some omega-3s. Omega-3 supplements, containing at least 500 milligrams, are recommended for individuals not meeting their fish intake goals.
Non-fish eaters can explore algae oil supplements, an alternative source of omega-3s utilized even by fish themselves.
