You may have heard about omega 3’s and their benefits for years, but now a less known type of fat is finally getting its turn in the spotlight. Omega 7 fats are gaining attention for their potential to reduce risk factors for heart disease, type 2 diabetes, and other obesity-related diseases. But as is often the case with health hype, the information is not clear. Do omega 7s really have as many health benefits? And if so, which foods have these fats in plenty? In this article, we will discuss what omega 7s are and which omega 7 foods you need to consider if you’re looking to increase your consumption of these.
What Is Omega 7?
Omega 7 is an unsaturated fatty acid that has a range of health benefits. Unsaturated fats, with the exception of omega 3s and omega 6s, are also known as non-essential fatty acids. That’s because they aren’t needed in our diet for survival but can be beneficial to health when consumed by humans or animals. The body synthesizes non-essential fatty acids on its own.
Palmitoleic acid is one of the acids that make up the omega 7 group. It is one of the most common omega 7s and has many possible health benefits (8).
Benefits Of Palmitoleic Acid
The human body can produce palmitoleic acid. This omega 7 fatty acid is found in your tissue and liver. But research has found that there may be benefits of ingesting dietary palmitoleic acid .
Here are the potential benefits of palmitoleic acid:
May Support Heart Health
Palmitoleic acids have been shown in studies to be associated with an improved ratio of LDL-cholesterol: HDL cholesterol, which is linked to a lower risk for cardiovascular disease.
(21). Palmitoleics also increased the amount of both omega-18s as well as oleic and linolenic acids in blood plasma. However, this remains controversial as other studies have had conflicting results.
Supports Insulin Sensitivity
Palmitoleic acid may prevent the breakdown of insulin and help it work more effectively (4). In addition, palmitoleic acid may support blood sugar control by preventing spikes in glucose levels and reducing inflammation that contributes to type II diabetes. It is also associated with an increase in the sensitivity of muscle cells that respond to insulin. Again, studies have found conflicting results in this area so it is far from completely understood.
Reduces Inflammation And Swelling
Palmitoleic acid may help reduce inflammation-causing molecules called cytokines. Palmitoleic acid has also been seen in mice to promote a molecule that reduces the production of cytokines. This helps stop chronic inflammation and swelling (14). Palmitoles produce an anti-inflammatory effect on the skin when applied topically to prevent dermatitis from occurring or worsening.

Satiety is the feeling you get after eating a meal and not having any hunger pangs for a certain period of time. Palmitoleic acid may be able to help control appetite by activating cholecystokinin receptors on your brain cells and increasing the levels of the satiety hormone cholecystokinin (12). This benefit could potentially help people with health problems that have trouble controlling their weight or appetite, like diabetes or obesity.
May Support Skin Health
Omega 7 acids inhibit inflammation and may promote collagen synthesis through the activation of Silent information regulator 1 (SIRT1). The accumulation of excess reactive oxygen species (ROS) as a result of oxidative stress accelerates skin aging. In-vitro studies show that omega 7 fatty acids have anti-inflammatory properties and promote collagen regeneration in the presence of hydrogen peroxide cytotoxicity (11). This slows the aging process and promotes skin health.
What Foods Contain Omega 7 Fatty Acids?
Eating foods high in Omega 7 gives you the beneficial properties of palmitoleic acids. Here is an omega 7 foods list for you to use in improving your diet.
Fish like salmon, herring, and mackerel are good sources of omega 7 fatty acids. Studies associate a higher fish intake with slower cognitive decline and a reduced risk for Alzheimer’s (6). Omega-fatty acids, which are plentiful in oily fish like salmon and mackerel, may help reduce inflammation throughout the body.
Fish is an excellent source of omega-three fatty acids for overall health as well (10). The benefits include helping with arthritis pain by reducing joint inflammation; lowering triglycerides (blood fats); improving heart function; lowering blood pressure; protecting against stroke and depression.

Sea buckthorn is a plant that grows in the Himalayas and is one of the omega 7 rich foods (1). It’s also a rich source of vitamin C, calcium, iron, carotene, and flavonoids that boost immunity.
Sea buckthorn juice combined with fresh lime juice is said to be good for health issues including:
- high blood pressure,
- diabetes mellitus type II,
- chronic inflammation of the lungs or skin (dermatitis herpetiformis),
- psoriasis of the scalp,
- peptic ulcers in adults,
- other diseases caused by oxidative stress.
Avocado oil is one of the best natural sources of omega-seven, as well as vitamin E (3). Avocados contain about three grams of monounsaturated fat per 100grams and are a good source for other essential nutrients including beta carotene, niacin, riboflavin, and folate (7).
Consuming avocados can lead to weight loss due to their high levels of fiber which slows digestion speed leading to fuller stomachs with smaller meals. This in turn causes less food consumption throughout the day. In addition, avocado oil contains heart-healthy fats such as oleic acid and palmitoleic acid which help reduce cholesterol levels for lowering risk factors associated with cardiovascular disease.
Macadamia Nuts And Oil
Macadamia nuts and oil are some of the foods with omega 7 (13). According to the University of Maryland Medical Center, macadamia nut oil is one of your best sources of omega fats. Of all oils, it has the highest proportion of omega-7 fatty acids. This oil also contains alpha-linolenic acid, omega-12 fatty acids, and omega-13.
Macadamia nuts contain about 40% of the total fat content as oleic and 80% of the fats are monounsaturated fats (9). They also have a reasonably large amount of polyunsaturated fats, but they don’t require any cooking to break down their natural antioxidants which is why many people like them raw.
Olive oil is a staple of the Mediterranean diet, which has been shown to improve longevity and reduce chronic diseases (5). It’s rich in omega-seven fatty acids, so it also helps you maintain your weight by enhancing metabolism. In fact, some studies have found that people who follow a Mediterranean diet (which involves consuming olive oil every day) may be at lower risk for obesity than those who don’t (2).
Some oils such as corn or soybean are high in polyunsaturated fats but contain little to no healthful monounsaturated fat like olive oil does; others such as coconut oil provide beneficial nutrients but are high in saturated fat (which may raise cholesterol levels). Olive oil offers all these benefits plus its versatility makes it an excellent choice for cooking.
Olive oil is also rich in antioxidants, which offer strong protection against heart disease and cancer as well as many other chronic diseases (15). Eating a diet high in these fatty acids has been shown to lower levels of bad cholesterol (LDL) while increasing good cholesterol (HDL).
