C-Force: Healthy Oils a Slippery Subject

This is a commentary about oil. Not the crude stuff, but the various extracts that have been used, some since the beginnings of recorded history, to improve human health. I was reminded of this practice recently when I stumbled upon this Medical News Today headline: "Could fish oil benefit people at high risk of Alzheimer's disease?"

"Many claims have been made for the health benefits of fish oils," Medical News Today's Katharine Lang writes. A recent study published in JAMA Network Open "found that taking fish oil supplements in later life could help reduce the risk of Alzheimer's in some people," specifically those who possess the APOE4 gene, which increases the breakdown of nerve cells in the brain, increasing the risk of developing Alzheimer's disease. "Experts suggest that larger clinical trials should investigate the benefits of omega-3 supplements for those at high risk of Alzheimer's," reports Lang.

Adds Dr. Steve Allder, a consultant neurologist at Re:Cognition Health, "This study highlights the potential for personalized nutritional interventions based on genetic predisposition. The results are promising, but more extensive research is necessary to fully understand the implications and to establish definitive guidelines."

While "fish oil may be a potential preventive treatment for some," Lang writes, the authors of the study "do not advise the use of fish oil supplements by all older people."

According to Molly Rapozo, a registered dietician nutritionist and senior nutrition and health educator at Pacific Neuroscience Institute in Santa Monica, "fish oils are generally safe, but people should take them only under medical advice," Lang writes. "(Rapozo) added that it is preferable to increase the omega 3 in your diet."

"Up your intake of small cold-water fish which are good sources of omega 3 fats," Rapozo advises.

At the same time, there are constant reminders of the role that plant-extracted oils play in our lives. Which brings us to essential oils, and the wide range of plant-extracted oils that "capture the plant's scent and flavor, or 'essence,'" as defined by Healthline.

John Landry is a registered respiratory therapist. Since 2016, "helping patients breathe easier has been my primary focus," he writes. In an April commentary piece for Respiratory Therapy Zone, he reminds readers of how "the health of our lungs is crucial for our overall well-being" and "a fundamental part of our existence."

He reminds us that of the "many factors that can affect lung health, from pollution to genetics, one area that has been gaining attention in recent years is the use of essential oils."

While essential oils "have been used for thousands of years for their medicinal properties," many health claims associated with these oils remain controversial. According to a Grandview Research report, the essential oils market is global, huge and growing. It was valued "at USD 23.74 billion in 2023 and is expected to grow at a compound annual growth rate (CAGR) of 7.6% from 2024 to 2030." Because of the controversy surrounding the subject, I will try to tread lightly when discussing it in a manner that's not interpreted as an endorsement, but as information.

Based on his background and experience in respiratory care, Landry believes that "whether you're dealing with asthma, allergies, or just looking for ways to enhance your lung function, these essential oils may provide some relief and help you breathe easier." Topping his list of "Best Essential Oils for Breathing" is black seed, a plant native to South Asia, the Middle East and Africa. It has "been used for thousands of years in traditional medicine for a variety of health benefits," Landry writes. "Black seed is believed to have anti-inflammatory, antibacterial, and antifungal properties and may help to support immune function and promote overall health and well-being." It is "used as a natural remedy for conditions such as asthma, allergies, digestive problems, and skin conditions."

Eucalyptus oil, derived from evergreen eucalyptus trees, is "more commonly used for medicinal purposes," Landry writes. "It has a variety of therapeutic properties, including being a natural decongestant and expectorant, making it beneficial for promoting respiratory health, clearing mucus, and treating allergic rhinitis symptoms. ... It is also used in a variety of commercial products, such as cough drops, chest rubs, and even insect repellents.

"Essential oils have proven to be a natural and effective way to enhance breathing and promote respiratory health, "Landry continues. "Eucalyptus, peppermint, black seed, bergamot, and mullein are among the best essential oils for breathing. However, it is important to note that essential oils should not replace medical treatments or medications prescribed by your healthcare provider. ... It's always advisable to speak with a medical professional before using essential oils, especially if you have a pre-existing condition. With the proper guidance and precautions, essential oils can be a valuable addition to your respiratory health routine."

Dr. Trisha Pasricha is a gastroenterologist at Massachusetts General Hospital, and an instructor of medicine at Harvard Medical School. In a July report in The Washington Post, she points out the lack of "convincing data from clinical studies" to support many of the claims of certain essential oils' medical benefits. "But there is reasonable medical evidence for a few," Pasricha writes. "Peppermint oil capsules for irritable bowel syndrome; Lavender oil capsules or aromatherapy for sleep and anxiety; Tea tree oil applied topically for acne.

"Essential oils are generally not regulated as medications by the Food and Drug Administration in the United States, so it can be hard to know what exactly you're getting when you buy these over-the-counter or online," she warns.

"I have no problem with my patients incorporating the oils in a personal care routine if doing so makes them feel luxurious," Pasricha continues. "But to me, the more important question if you suffer from poor sleep is not whether lavender essential oil will help your symptoms, but whether we can address the underlying issue causing it. Similarly, for anxiety, we still need to find a long-term solution."
