Omega-3 fatty acids are polyunsaturated fats, a type of fat your body cannot make. The body cannot make them, but the body needs them.
The term “polyunsaturated” refers to the number of double bonds in fats. Together, these compounds have double bonds, which means that they have many double bonds.
“Omega-3 refers to the position of the final double bond in the chemical structure, which provides a balance between omega-6 and omega-3 fatty acids.” Which is three carbon atoms from the prime end of the molecular chain.
The human body cannot produce omega-3s, so they are referred to as ‘essential fats’. That means you must get them from your diet. The American Heart Association recommends eating at least two servings of fish per week, particularly oily fish, which is rich in omega 3 fatty acids.
Fatty acids differ based on their structure, which is one of the reasons why there are several different types of fatty acids. Here are the three most common fatty acids:
Eicosapentaenoic acid (EPA): This 20-carbon fatty acid’s main function is to produce chemicals called eicosanoids, which help reduce inflammation. EPA may also help reduce depression symptoms.
Docosahexaenoic acid (DHA): A 22-carbon fatty acid, DHA contributes to brain development and function.
- Alpha-linolenic acid (ALA): This 18-carbon fatty acid can be converted into EPA and DHA, although the enzyme is not very efficient. ALA benefits the heart, immune system, and nervous system.
- Omega-3 fatty acids are a crucial part of human cell membranes. They also have other important functions, including:
- Improving heart health, fish oil may help manage cholesterol, triglyceride, and blood pressure levels.
- Omega-3 supplements can help manage or prevent depression, Parkinson’s disease, and psychosis in those at risk. However, it is still unknown whether they can help manage or prevent depression, Parkinson’s disease, and psychosis in those at risk.
- Reducing weight and waist circumference, Omega-3 fats may result in people managing their weight and waist circumference, but multiple studies have shown.
- Early research suggests that consuming omega-3s may help decrease the amount of fat in your liver.
- Facilitating infant brain development, Omega-3s facilitate brain development in a fetus.
- Treating inflammation with omega-3 fats may help manage the inflammation that occurs with some chronic diseases.
- A low intake of omega-3 fatty acids compared with omega-6s may increase inflammation and could lead to chronic diseases, such as rheumatoid arthritis, diabetes, atherosclerosis, and heart failure.
Omega-3 fats are among the most studied nutrients. They are required by our bodies to produce hormones and cellular membranes, and they can help lower blood pressure and improve heart health.
The omega-3 fatty acids are phenomenally abundant in foods like walnuts, seafood, fatty fish, and certain seed and plant oils. They are classified into three types: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
Omega-3 fatty acids have been known to have a range of health benefits, including their potential to fight depression, lower inflammation, and reduce markers of heart disease. One less well-known perk is that it may benefit your skin and hair.
Beneficial to Your Hair
Omega-3 supplements are made from fatty acids found in cold-water fish, including salmon, sardines, herring, anchovies, and mackerel. Omega-3s are also available in supplement form. While it’s unclear why omega-3 may promote hair growth in some people, there are several possibilities.
Omega-3 for hair is a nutritional supplement injected with EPA, DHA, and gamma-linolenic acid (GLA) to promote hair growth and stop/slow down excessive hair shedding and thinning. Omega-3 may help provide the essential proteins and nutrients to cells within the scalp and follicles. It can also prevent inflammation of these cells that directly contributes to hair loss. Omega-3 also promotes circulation in the scalp that may trigger new hair growth.
If you are dealing with thinning hair, omega-3 supplements may be worth a try. Omega-3 fatty acids may help thicken the hair follicles and promote healthy hair growth.
They Protect Your Skin from the Sun
Omega-3 fatty acids are key anti-inflammatories. Research shows that fats help protect skin cells against sunburn and help control how the body responds to UV rays, thereby preventing damage. Several studies have shown that unprotected skin does not burn as quickly in people who take fish oil supplements and sunlight. Omega-3 fatty acids have been shown to strengthen cell membranes, which protect other areas of the cell from oxidative stress.
They Fight Wrinkles
A healthy diet, regular exercise, and avoiding pollution can reduce inflammation in your body, which can make your skin less sensitive when you make expressions. Wrinkle lines can occur around the eyes and mouth and on the forehead. Eating more foods rich in omega-3 fatty acids, like arctic char, chia seeds, spinach, and kidney beans, supports your skin’s structure, reducing the appearance of fine lines.
They Keep Your Skin Hydrated
Omega 3’s are crucial to your skin’s lipids and, when working properly, acts to boost your skin’s barrier function, which keeps moisture in and irritants out. When your skin is compromised, then your skin becomes dry, it becomes rough, and it becomes prone to irritation. We found that women who consumed half a teaspoon of omega-3-rich flaxseed oil daily had 39% increased skin hydration after 12 weeks.
Although most of the benefits from oils come from ingesting these healthy fats, they can nourish skin from the outside too. Omega-3s and their sister essential fatty acids, omega-6s, both of which are found in skin, can be effective moisturizers when applied topically, are thought to help with skin conditions such as acne and psoriasis. Apply these fatty acids daily on your body, you will feel the benefits in your skin.
Plant oils rich in omega-3 and omega-6 are used in many products, though it is hard to find products, such as flaxseed, safflower, sunflower, and olive, which are commonly used in cleansers, body and face lotions, body oils, and even lip balm.
May Reduce Acne
A diet rich in omega-3s may help prevent acne.
New evidence suggests that acne may be caused by inflammation and that omega-3s may indirectly fight acne. A few studies have reported that taking omega-3 supplements helps reduce acne lesions. Omega-3 supplements can effectively alleviate the side effects of isotretinoin, a drug commonly used in severe or resistant cases of acne.
However, there have been few studies specifically, to examine what effect cholesterol-lowering fish oil has on individuals and the effect appears to vary by individual. Thus, more research is needed.
May Guard Against Dry, Red, or Itchy Skin
Omega-3s may help moisturize the skin and fight red, dry, or itchy skin. Because of the effects of omega-3s, and improved skin barrier function can be noted.
A study was conducted to see if there is a link between a high intake of Omega 3 and a lower risk of atopic dermatitis in infants. But other studies have been unable to replicate these results. There are a variety of dose and delivery modes used between studies that may partly account for the conflicting findings.
Foods High In Omega-3 Fats
Omega-3 fats are the most important fatty acids. Evidence suggests that omega-3s can help protect against heart disease, arthritis, cancer, and depression. Foods high in omega-3 fats include fish oils, flaxseed oil, canola oil, nuts, or seeds. Here are the amounts of each type of omega-3 fat in one serving of the following foods:
- salmon: 4.0 grams EPA and DHA
- mackerel: 3.0 grams EPA and DHA
- sardines: 2.2 grams EPA and DHA
- anchovies: 1.0 grams EPA and DHA
- chia seeds: 4.9 grams ALA
- walnuts: 2.5 grams ALA
- flaxseeds: 2.3 grams ALA
The Best Plant Sources of Omega-3 Fatty Acids
Omega-3 is an essential fatty acid shown to promote general health and well-being. It is known to support the normal function of the brain, heart, joints, and immune system, and may help reduce the risk of certain diseases like heart disease.
The challenge is that the human body needs EPA and DHA to function correctly. These two fatty acids are not produced in plants or animals, but only by the microalgae that live in both marine and freshwater.
1. Chia Seeds
Chia seeds are tiny, round, black-colored seeds that are packed with nutrients. They are rich in ALA omega-3s, fiber, protein, and other essential nutrients. Other health benefits include improved heart health. Their tiny size means you will not feel them once they have hydrated.
Chia seeds and nopal, a natural vegetable fiber that is added to many foods and drinks, are just two of the ingredients in this unique product. Its unique fiber matrix helps slow the absorption of liquid, so you feel full faster. Its fast-absorbing liquid form can be taken as a drink, as well as mixed into any food or beverage as an ingredient. It also includes omega-3 fatty acid-rich chia seeds and nopal as well as soy protein and oats. This dietary supplement is vegan and is formulated without yeast, wheat, gluten, milk, sugar/sweets, preservatives, artificial flavor.
2. Brussels Sprouts
This meal hits all the nutritional high points—nutritionists recommend Brussels sprouts as a superfood for their fiber, vitamins K and C, folate, vitamin B6, omega-3 fatty acids, and phytonutrients.
Because of their high vitamin K levels, Brussels sprouts have been shown to improve bone health as well as inhibit cancer cell growth.
Power up your meals with these nutrient-packed sprouts. Brussels sprouts are cruciferous vegetables, which means they contain cancer-fighting compounds called glycosylates.
Packed with nutrients and naturally cholesterol and gluten-free, our flaxseed provides a useful source of the omega 3 fatty acids that everyone is talking about. With just 2 tablespoons you can sprinkle some on your oatmeal for breakfast, add them to a salad dressing for an afternoon snack, or grind them up in a coffee grinder to include in your favorite baked goods.
Flax is a rich source of ALA omega-3 fatty acids. Flaxseeds contain more than sixty percent of the daily recommended intake of ALA omega-3 per ounce (28 g). Omega-3’s are known to benefit cardiovascular health and may also help with inflammation and pain management.
Flaxseed is a great alternative to more traditional seeds. With a mild yet slightly nutty flavor, flaxseed also makes the perfect addition to cereal, oatmeal, soups, or salads.
