Seed Oils Vs. Beef Tallow: What You Need to Know

Seed oils: Superfood or scapegoat? Discover the truth about their impact on your health and why moderation matters!

Highlights:

Seed oils, rich in omega-6 and polyunsaturated fats, can promote heart health when consumed as part of a balanced diet
The criticism of seed oils stems from their presence in processed foods, but the oils themselves are not the direct cause of obesity or inflammation
Alternatives like olive, avocado, or peanut oil are great, but seed oils remain affordable and heart-healthy choices when used correctly

Seed oils like canola and sunflower oil are frequently used in processed foods like baked products. These days, several wellness influencers say that they are staying away from seed oils since they contain inflammatory and harmful omega-6 fatty acids (). Seed oils are one of the driving causes of the obesity epidemic.

Seed Oils Can Help Reduce Your Bad Cholesterol Levels
Adding seed oils in your diet can help you to reduce your bad cholesterol levels. A new study highlights that sunflower oil, rapeseed oil, safflower oil, and flaxseed oil were the best choice to lower LDL cholesterol levels.

Hate Eight- Seeds Oils to Avoid

Seed oils are frequently referred to as the "Hateful Eight" by social media users. Canola (rapeseed), corn, soybean, sunflower, cottonseed, safflower, grapeseed, and rice bran oils are all included in this category (). Influencers who advocate against seed oils frequently share videos from supermarkets, urging their followers to stay away from anything that contains these oils.

However, many people find it difficult to stay away from seed oils. These oils are found in many meals in the United States, particularly in processed foods, which account for 60% of the average American diet (). Sunflower or soybean oil is frequently listed on the ingredient labels of everyday products like bread, popcorn, and chips.

Judy D. Simon MS, RD, CD, a registered dietitian nutritionist at the University of Washington Medical Center, said, "The oil itself has really been demonized, even though many ultra-processed foods have lower nutrient densities."

Olive Oil More Stable and Healthful Than Seed Oils for Frying Food, Says Study
A new study published in Journal of Agricultural and Food Chemistry finds that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.

The Return of Beef Tallow in the US

McDonald’s cooks its fries in a canola oil blend (), but Robert F. Kennedy, Jr., the Trump administration’s nominee to run the Department of Health and Human Services, has pushed for a return to beef tallow, which was utilized until 1990. Kennedy stated in an Instagram post, "This change was made because saturated animal fats were thought to be unhealthy." Overconsumption of saturated fat can increase "bad" cholesterol levels, which raises the risk of stroke and heart disease.

Avoiding seed oils might be challenging, even if you completely avoid fast food. However, is it really necessary to stay away from seed oils in order to keep up a healthy diet?

Is Canola Oil Healthy?
Canola oil is a genetically modified rapeseed oil. Compared to saturated oils it reduces abdominal fat and bad cholesterol. It is rich in vitamin E and MUFA.

Health Advantages of Seed Oils

Dietary fats and oils are a mixture of healthy fats, like polyunsaturated and monounsaturated fats, and less healthy saturated fats (), (). Omega-3 and omega-6 fats are examples of polyunsaturated fats. Omega-3s are more abundant in fatty fish, but omega-6s are more abundant in seed oils ().

Reducing saturated fats and increasing unsaturated fats is advised by the Dietary Guidelines for Americans (). Additionally, the American Heart Association advises against consuming trans or saturated fats in favor of monounsaturated and polyunsaturated fats, such as those found in tofu, nuts, and seed oils ().

"Over the years, studies have demonstrated that consuming these polyunsaturated fats has been associated with a decreased risk of death from cancer and cardiovascular disease, thereby providing positive health benefits," Simon added.

Studies have demonstrated that daily consumption of linoleic acid, the main omega-6 in seed oil, does not raise blood inflammatory markers, unlike what some people on social media have claimed (). In fact, linoleic acid may help reduce the risk of heart disease ().

According to Grace Derocha, RDN, CDCES, MBA, a registered dietitian nutritionist located in Detroit and an Academy of Nutrition and Dietetics representative, "concerns regarding omega-6s driving inflammation are often overemphasized and not strongly supported by large-scale evidence."

Another reason why some people choose to stay away from seed oils is oxidation. Unsaturated fatty acids can oxidize and release free radicals when exposed to heat and light (). Compared to saturated fats, unsaturated fatty acids- particularly linoleic acid- oxidize more quickly ().

"Using cooking techniques like sautéing over moderate heat, avoiding prolonged high-heat frying, and properly storing oils can mitigate the risk of oxidized fats producing potentially harmful byproducts," Derocha stated.

Canola Oil Helps Reduce Abdominal Fat in Four Weeks
Canola oil is a type of rapeseed oil that benefits health. A new study claims that canola oil can reduce abdominal fat when included in the diet for four weeks.

Is Beef Tallow Healthier Than Seed Oils?

Protein and carbohydrate sources have four calories per gram, whereas seed oils, like all fats, have nine (). "A surplus of calories and consequent weight gain can result from consuming too many calorie-dense foods, including those that contain seed oils," Derocha stated. However, blaming seed oils alone is not supported by the facts.

The main reason for the criticism of seed oils is that they are frequently found in highly processed meals that are easy to overindulge in, high in calories, and low in nutrients, such as baked products, fried snacks, and fast food. Weight gain is caused by the total dietary pattern more than the amount of seed oils, according to Derocha.

You can also use beef tallow. One kind of rendered fat produced by boiling down fatty cow tissues is called beef tallow (). It has very little polyunsaturated fat and primarily monounsaturated and saturated fatty acids.

Saturated fats are scarce in seed oils. One tablespoon of beef tallow has more than six grams of saturated fat, whereas one tablespoon of canola oil has less than one gram and one tablespoon of sunflower oil has 1.36 grams (), (), (). To put it another way, 3 tablespoons of beef tallow would nearly fulfil the daily need of 20 grams of saturated fat (). The American Heart Association advises consuming no more than 13 g of saturated fat per day ().

Because of its high saturated fat content, which prevents oxidation during frying, tallow is more heat-stable, according to Derocha. "The higher saturated fat content may not be in line with heart-health guidelines if consumed in large amounts over time, even though oxidation is less of an issue."

Other options for those who choose not to use seed oils are peanut, avocado, and olive oils, which are higher in monounsaturated fat (). But these oils are frequently more expensive than seed oils.

Despite social media criticism, studies reveal that seed oils like canola and sunflower oil contain healthy polyunsaturated fats that, when taken in moderation, may promote heart health. Focus on a balanced diet that includes a range of healthful fats and less processed foods rather than completely eliminating seed oils.
