Omega-3 fatty acids are essential nutrients that the human body cannot produce from scratch. While a small amount of some omega-3 types can be converted internally, the question of whether omega-3 is synthesized in the body is complex and largely points toward a dietary necessity.

Docosahexaenoic acid (DHA) is a critical omega-3 fatty acid, comprising over 90% of the omega-3s in your brain and playing a vital role in cellular function. Since the human body can't produce adequate amounts, obtaining it from natural dietary sources is essential for brain, eye, and heart health.

While walnuts are packed with omega-3s, studies show that only a small percentage of their plant-based alpha-linolenic acid (ALA) is efficiently converted into docosahexaenoic acid (DHA). This raises the critical question for health-conscious individuals: can you get DHA from walnuts in a meaningful way, or is a different strategy needed for optimal intake?

Just one ounce (28g) of chia seeds contains an impressive 5 grams of ALA omega-3, making them a popular choice for plant-based diets. However, the real question isn't how much ALA they contain, but whether you can get enough omega-3 from chia seeds once your body processes them for use.

According to the National Institutes of Health, the three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). This leads many to question: does peanut butter have EPA? A crucial distinction exists between the types of omega-3s found in different food sources.

Over 70% of Americans are not consuming enough long-chain omega-3 fatty acids, which are most famously found in fish. Fortunately, obtaining essential EPA and DHA does not require consuming seafood, as several effective non-fish sources exist for those following vegetarian, vegan, or pescatarian diets.

Despite being one of the richest plant-based sources of omega-3s, multiple studies indicate that the body only converts a small fraction of the alpha-linolenic acid (ALA) in flaxseed into the more active forms, EPA and DHA. This low efficiency raises a critical question for plant-based diets: can I get enough omega-3 from flaxseed for optimal health?

According to the National Institutes of Health, adult males typically need 1.6 grams and females need 1.1 grams of the omega-3 fatty acid ALA per day. Flaxseed is one of the richest plant-based sources of this essential nutrient, making it a popular addition to many diets. However, ensuring you consume the right amount is key to reaping its full benefits.

Human studies show the conversion of the plant-based omega-3 alpha-linolenic acid (ALA) to EPA is typically less than 10%, with conversion to DHA being even lower. This article explains the low conversion rate of ALA to EPA and DHA and the factors that influence it.

Approximately 95 percent of Americans do not get enough EPA and DHA, highlighting a widespread nutritional gap. The reason for this deficiency lies in a crucial biological fact: the human body cannot make omega-3s from scratch and relies heavily on external dietary sources.
