Omega-3 or fish oil is the second most common supplement taken on a daily basis after multivitamins among those who take supplements in the US. But if you don't want to take fish oil for any reason (you don't eat fish or you don't like to have that much oil in your diet) there are other ways to get your Omega-3 needs met, including whole foods that are high in Omega-3 such as seeds, nuts, and beans. Here are exactly what foods to add for Omega-3.

Since the body can't produce these fatty acids on its own, these essential fats must come from the food you eat. They offer unique health benefits, including boosting mood, brightening dull skin and fighting inflammation. Specifically, Omega-3s have been shown in studies to lower blood pressure,  regulate heart rate, improve blood vessel function among others. Omega-3s are also important in regulating brain function and help boost your mood, so if you are feeling a little distracted or down, it may be that you are Omega-3 deficient.

Men and women require different doses of Omega-3s, according to the National Institutes of Health: Women should aim for 1.1 grams whereas men need around 1.6 grams daily. An Omega-3 deficiency is rare, but if you notice your skin is rough and scaly or you develop eczema, a shortage of Omega-3 may be one contributing factor. The symptoms of Omega-3 deficiency aren't always physical but can be mental or emotional, and include intensifying symptoms of depression, anxiety, or lack of focus.

Omega-3s come in three different types: EPA, DHA, and ALA. Both EPA and DHA are found in fish oil and algae, but ALA is mostly found in whole, plant foods such as nuts, beans and other legumes. The body needs to convert ALA, alpha-linolenic acid (ALA) into more active forms of Omega-3 fatty acids EPA and DHA. Think of ALA  as the building block to allow your body to get what it needs, so generally a plant-based dieter needs to eat more of these nutrients to reach their daily recommended amount. Here are the seven whole, plant foods that will help you reach your daily recommended amount of Omega-3 needs.

1. Chia Seeds are one of the best sources of Omega-3s, with 5 grams per ounce
