Omega-3 fatty acid facts for kids

Omega-3 fatty acids, also called omega-3 oils, are a type of healthy fat. They are very important for your body to work well. You can find them in many foods, and they play a big role in your health.

There are three main types of omega-3s that are important for people:

• ALA (alpha-linolenic acid)
• EPA (eicosapentaenoic acid)
• DHA (docosahexaenoic acid)

You can find ALA in plants, like walnuts and flaxseeds. EPA and DHA are mostly found in fish and algae. Fish get these healthy fats by eating algae and smaller fish that have eaten algae.

Why Omega-3s are Important

Your body needs omega-3s to stay healthy. They are called "essential" fats because your body cannot make them on its own. This means you have to get them from the food you eat.

Once you eat ALA from plants, your body can try to change it into EPA and then into DHA. This process helps your body use the ALA you eat. However, this conversion might not be very efficient, especially as people get older.

Omega-3s are important for many parts of your body. They help your brain, eyes, and heart. They also help reduce inflammation, which is how your body responds to injury or sickness.

Where Do We Get Omega-3s?

You can get omega-3s from many different foods.

Plant Sources (for ALA)

• Walnuts: These nuts are a great snack and full of ALA.
• Flaxseeds: You can add ground flaxseeds to smoothies or oatmeal.
• Chia seeds: Another tiny seed packed with ALA.
• Hempseed oil: This oil can be used in salad dressings.

Fish and Algae Sources (for EPA and DHA)

• Fatty Fish: Fish like salmon, mackerel, and sardines are rich in EPA and DHA.
• Fish Oils: These are supplements made from fish, but it's often better to get omega-3s from food.
• Algae Oil: This oil comes directly from algae and is a good plant-based source of EPA and DHA.

Omega-3 Supplements

Some people take omega-3 supplements, like fish oil pills. However, studies have shown that taking these supplements might not prevent serious health problems like heart attacks or strokes. It's usually best to get your omega-3s from a balanced diet with plenty of fish and plant sources.

Different Kinds of Omega-3s

There are many types of omega-3 fatty acids. Here are some of the most common ones you might hear about:

• ALA (alpha-linolenic acid): Found in plants.
• EPA (eicosapentaenoic acid): Found in fish and algae.
• DHA (docosahexaenoic acid): Found in fish and algae.

These different types have slightly different jobs in your body, but they all work together to keep you healthy.

How Omega-3s are Stored

In nature, omega-3 fatty acids are usually found in two main forms:

• Triglycerides: This is how fats are mostly stored in your body and in many foods. They are made of three fatty acids connected to a molecule called glycerol.
• Phospholipids: These are important parts of cell membranes. They have two fatty acids connected to a phosphate group and glycerol.

Both forms are important for your body.
