Soybean Oil Innovations: Coming to a Plate Near You
A guide for health professionals
Soybean Oil Reaches New Heights
Soybean oil is one of the most abundant vegetable oils in the world. In fact, most "vegetable oil" available on grocery store shelves is U.S.-grown 100 percent soybean oil. Conventional soybean oil contributes 0 grams trans fat and is a principal source of alpha-linolenic acid (ALA), an omega-3, in the U.S. diet.
Improvements in the health profile of soybean oil could positively impact the public due to its anticipated extensive use in the foodservice and food manufacturing industries. It is important for health professionals to be aware of these improvements and what they mean to their patients and clients.
Consumers Want to be Healthier
People want to eat healthier and are looking for simple ways to do it. The soybean industry is committed to making it easier for food companies to deliver products that meet consumer health and nutrition needs– starting with better-for-you oil solutions. New soybean varieties produce oils with a healthier profile and improved functionality.
High Oleic Soybean Oil Improves Product Nutrition
High oleic soybean oil offers a healthier fat profile, improved functionality and 0 grams trans fat. The oil allows foodservice operations and food manufacturers to eliminate the use of trans fats while providing superior performance and stability.
High oleic soybean oil delivers three times the amount of beneficial monounsaturated fatty acids (MUFAs) compared to conventional soybean oil, which may benefit heart health. A high MUFA content makes this oil extremely stable, eliminating the need for partial hydrogenation.3-4
- MUFAs, such as oleic acid, benefit heart health when eaten in moderation and used to replace saturated fats or trans fats. MUFAs may also help reduce LDL levels in the blood, reducing the risk of heart disease and stroke.5
- Studies have shown that MUFAs reduce blood pressure. It has been demonstrated that the oleic acid component contributes to this hypotensive effect.6
- Substituting saturated fat with monounsaturated fat improves insulin sensitivity and reduces plasma triglycerides, making it an important dietary modification for those at risk of metabolic syndrome.7
- High oleic soybean oil is a significant provider of vitamin E and contains a number of phytosterols, including B-sitosterol, campesterol and stigmasterol.8-9
High in MUFAs, high oleic soybean oil is stable and does not require hydrogenation, making it a better-for-you replacement for saturated fats.4,10-11
High Oleic Soybean Oil is Available Now
Today, U.S. soybean farmers collaborate with seed technology companies to ramp up crop production and accelerate the supply of high oleic soybeans. High oleic soybean acreage and oil production is expected to more than double year upon year, resulting in 9.3 billion pounds of available oil within the next decade. QUALISOY® projects the supply of high oleic soybean oil will be greater than other high oleic offerings due to the amount of available soybean acreage in North America.
High oleic soybean oil was commercialized in 2011 and is available now. Quantities are increasing and expected to reach an estimated 1 billion pounds by 2018.12
Enhanced Soybean Oils in the Pipeline: Increased Omega-3
Omega-3 fatty acids are both essential and beneficial for human health. Research shows diets rich in omega-3 fats reduce inflammation and may help lower risk of chronic diseases such as heart disease.17
The long-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found primarily in fatty fish and marine sources, are most readily used by the body. Although ALA, the type of omega-3 found in soybean oil, is the principal source of omega-3s in the U.S. diet18, ALA is not efficiently converted to EPA and DHA in the body.
Companies are developing soybeans rich in stearidonic acid (SDA), an omega-3 fatty acid. SDA omega-3s are more efficiently converted by the body into EPA than the ALA omega-3s found in plant sources.
This variety of soybeans will result in an affordable, land-based, renewable source of omega-3s.
The aim is to produce neutral-flavored soybean oil with 18 to 20 percent SDA. This SDA-rich soybean oil will provide the food industry with a functional ingredient that can be added to a variety of foods, such as soups, sauces, beverages, yogurts and breads.
Incorporating this type of omega-3 in foods could have tremendous public health benefits.19-20
Increased omega-3 highlights
- Companies developing these soybean varieties aim for an omega-3 content of 18 to 20 percent.
- Omega-3 fatty acids have potent anti-inflammatory effects that guard against coronary heart disease and autoimmune diseases.21
- SDA-rich soybean oil is an effective and environmentally sustainable approach to increasing heart-healthy levels of EPA in the body.22
Health and Environmental Benefits Through Biotechnology
Soybean oils developed through agricultural biotechnology can help consumers lead a healthier lifestyle; for example, it increases omega-3 fatty acid consumption and reduces saturated fat consumption. Agricultural biotechnology helps farmers provide a sustainable future for the world’s agriculture systems. Studies show that biotechnology significantly reduces agriculture’s impact to the environment, contributing to increased use of conservation tillage, improved water quality, conservation of topsoil and reduced pesticide use.23
Consumers and biotechnology
In the 2016 United Soybean Board Consumer Attitudes about Nutrition Survey, 40 percent of consumers believe modifying food through biotechnology is somewhat to very positive. Top reasons why include larger crop yields (22 percent), making food healthier (15 percent) and helps people (15 percent).2
The soybean industry is constantly working with academic researchers and industry experts to improve the nutritional profile and functional characteristics of soybean oil.
