Omega-3 fatty acids play a vital role in overall health, impacting heart, brain, and inflammatory responses throughout the body. Despite their importance, many people fail to get enough omega-3 from their diets, leading to potential health risks. This guide will cover the best omega-3 supplements, the most reliable food sources, signs of deficiency, and the benefits of omega-3 during pregnancy. We’ll also take a look at the omega profiles of fish and hemp seeds, two popular sources, to help you decide which is best for your needs.
What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are essential polyunsaturated fats that the body cannot produce on its own, meaning they must come from our diet or supplements. There are three main types of omega-3s:
- EPA (eicosapentaenoic acid): Primarily found in fish oils and known for its anti-inflammatory effects.
- DHA (docosahexaenoic acid): Found in fish oils and supports brain and eye health.
- ALA (alpha-linolenic acid): Found in plant sources like flaxseed, chia seeds, and hemp seeds; ALA is a precursor to EPA and DHA but needs to be converted in the body.
Omega-3s are necessary for maintaining cell structure, supporting cognitive function, and regulating inflammation.
Omega-3 Best Supplement: Finding the Right One for You
Supplements can be a convenient way to ensure you’re getting enough omega-3s, especially if you don’t consume fish regularly. Here are some of the best types of omega-3 supplements:
1. Fish Oil Supplements
Fish oil is one of the most popular omega-3 supplements because it provides EPA and DHA directly. Most fish oil supplements are derived from fatty fish like salmon, mackerel, and sardines. High-quality fish oil supplements are filtered to remove toxins like mercury, making them safe for regular use.
2. Krill Oil
Krill oil is derived from small, shrimp-like crustaceans and is gaining popularity as an alternative to fish oil. Krill oil contains EPA and DHA and may be more bioavailable, meaning the body can absorb it more effectively. Additionally, krill oil has antioxidant properties from astaxanthin, which adds extra health benefits.
3. Algal Oil
Algal oil is a plant-based source of DHA, making it an ideal option for vegetarians and vegans. Although it may be lower in EPA, algal oil is a sustainable and environmentally friendly source of omega-3s. Many algae-based supplements contain DHA, and some products are enriched with EPA for added benefits.
4. Flaxseed Oil and Hemp Seed Oil
Both flaxseed and hemp seed oils are rich in ALA, the plant-based omega-3. Although ALA must be converted to EPA and DHA, these oils still offer numerous health benefits. Hemp seed oil also provides additional nutrients, such as omega-6 and 9 fatty acids in an optimal balance for health.
Omega-3 Good Sources: Foods That Deliver
While supplements are convenient, there’s no substitute for whole foods as a source of omega-3s. Here are some of the best natural sources:
1. Fatty Fish
Salmon, mackerel, sardines, and trout are some of the richest sources of EPA and DHA. Eating two servings of fatty fish per week is generally recommended for heart health and to ensure adequate omega-3 intake.
2. Chia Seeds and Flaxseeds
Both chia seeds and flaxseeds are excellent sources of ALA, a type of omega-3 found in plants. They are also high in fibre and can easily be added to smoothies, oatmeal, or salads.
3. Hemp Seeds
Hemp seeds are another good plant-based source of ALA. They offer a balanced ratio of omega-3 to omega-6, promoting heart health and reducing inflammation. Hemp seeds also contain high quality protein and are packed with essential vitamins and minerals, including magnesium, iron and zinc.
4. Walnuts
Walnuts are rich in ALA and are an easy addition to your diet. A handful of walnuts each day can contribute to your omega-3 intake and offer antioxidants that support brain health.
5. Eggs (Omega-3 Enriched)
Many farmers now produce omega-3 enriched eggs by feeding hens a diet high in flaxseed. These eggs are a convenient source of DHA for those who may not eat fish.
Omega-3 Deficiency Symptoms: Signs to Watch Out For
An omega-3 deficiency can lead to various symptoms, as these fatty acids are crucial for brain, heart, and joint health. Here are some common signs that may indicate a lack of omega-3s:
1. Dry Skin and Hair
Omega-3s help keep cell membranes healthy, and a deficiency can lead to dry, flaky skin and brittle hair.
2. Joint Pain and Stiffness
Omega-3s have anti-inflammatory properties, so a lack of these fats can exacerbate joint pain or stiffness, particularly in conditions like arthritis.
3. Mood Changes and Cognitive Issues
Low levels of omega-3s, especially DHA, can impact mood and may contribute to conditions like depression and anxiety. Omega-3s also support cognitive health, and a deficiency could lead to memory issues or a decline in focus.
4. Eye Health Issues
Omega-3s, particularly DHA, play a vital role in eye health. Deficiency can increase the risk of eye problems, such as dry eyes and even age-related macular degeneration.
If you suspect an omega-3 deficiency, consider consulting a healthcare provider and increasing your intake of omega-3-rich foods or supplements.
Omega-3 When Pregnant: Supporting Baby’s Development
Omega-3 fatty acids are especially important during pregnancy, as they support the development of the baby’s brain, eyes, and nervous system. DHA, in particular, is crucial for these developmental processes. Pregnant women should aim to include omega-3 sources in their diet, especially in the third trimester when the baby’s brain is rapidly growing.
Studies suggest that sufficient omega-3 intake during pregnancy can also reduce the risk of preterm labour, promote healthy birth weight, and may support the mother’s mental health postpartum.
While it’s safe to take omega-3 supplements during pregnancy, it’s essential to choose a high-quality product, ideally one filtered to remove mercury and other contaminants. Fish oil, algal oil, hemp seed oil and omega-3 enriched foods can all help expectant mothers meet their omega-3 needs. And yes, hemp seed is safe to use while pregnant.
Fish vs. Hemp Seed Omega Profile: Which is Better?
Fish and hemp seeds are both excellent sources of omega-3, but they offer different benefits due to their unique omega profiles.
1. Fish
Fish, particularly fatty varieties like salmon and mackerel, is rich in EPA and DHA, the most bioavailable forms of omega-3. These types of omega-3s are directly used by the body for anti-inflammatory functions, brain health, and cardiovascular support. The immediate availability of EPA and DHA makes fish a highly effective omega-3 source, particularly for those at risk of heart disease or cognitive decline.
2. Hemp Seeds
Hemp seeds, on the other hand, are high in ALA, which the body can convert into EPA and DHA. However, hemp seeds offer a balanced omega-3 to omega-6 ratio, which is beneficial for managing inflammation. They are also packed with protein, fibre, and essential minerals, making them a great addition to plant-based diets.
In summary, if you’re looking for direct sources of EPA and DHA, fish is more efficient, but often difficult to consume in the recommended quantities. For those on plant-based diets, hemp seeds offer a valuable source of ALA and are a versatile, nutritious addition to meals. It is easy to incorporate hemp seed into your daily diet. This can be in the form of hemp seeds, hemp seed oil, or hemp seed oil capsules.
How to Incorporate More Omega-3s Into Your Diet
Ensuring an adequate intake of omega-3s doesn’t have to be complicated. Here are some easy ways to incorporate more omega-3s into your meals:
1. Add Fatty Fish to Your Weekly Meal Plan
Aim for at least two servings of fatty fish each week, whether it’s grilled salmon, sardine salad, or mackerel sandwiches.
2. Top Smoothies or Yogurt with Chia Seeds
Chia seeds are a great source of ALA and can be added to smoothies, yogurt, or overnight oats.
3. Snack on seeds and nuts
Keep a handful of nuts on hand for an easy, omega-3 rich snack.
4. Use Hemp Seed Oil
Drizzle hemp seed oil over salads or add it to homemade dressings for a healthy dose of ALA.
5. Consider Omega-3 Supplements
If dietary changes aren’t enough, consider a high-quality omega-3 supplement, especially if you’re pregnant or have signs of deficiency.
Conclusion
Omega-3 fatty acids are essential for good health, contributing to everything from brain function to heart health and inflammation control. Ensuring a sufficient intake of these essential fats can help prevent deficiency symptoms like dry skin, mood changes, and cognitive decline, while supporting key functions during pregnancy.
With options ranging from fatty fish and algae to plant-based sources like hemp seeds and walnuts, there are plenty of ways to get your omega-3s, whether through diet or supplements. Understanding the unique benefits of each source, such as fish for direct EPA and DHA and hemp seeds for plant-based ALA, can help you make informed choices to support your health and wellness.
