What is Coconut Oil?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Coconut oil, derived from the kernel or meat of mature coconuts, is a popular edible oil known for its unique composition and potential health benefits. It is rich in medium-chain triglycerides (MCTs), which are believed to offer various metabolic and therapeutic advantages. This article explores the properties, health implications, and scientific findings related to coconut oil. Other names include: Aceite de Coco, Acide Gras de Noix de Coco, Coconut Fat, Coconut Fatty Acid, Coconut Palm, Coco Palm, Cocos nucifera, Cocotier, Cold Pressed Coconut Oil, Fermented Coconut Oil, Huile de Coco, Huile de Noix de Coco, Huile de Noix de Coco Pressée à Froid, Huile Vierge de Noix de Coco, Narikela, Noix de Coco, Palmier, Virgin Coconut Oil.

Composition and Types of Coconut Oil

Coconut oil is primarily composed of saturated fats, with a significant portion being MCTs such as lauric acid, caprylic acid, and capric acid. There are two main types of coconut oil: virgin coconut oil (VCO) and refined coconut oil. VCO is extracted from fresh coconut meat without the use of high temperatures or chemicals, preserving its natural antioxidants and nutrients. Refined coconut oil, on the other hand, is processed to remove impurities and may lack some of the beneficial compounds found in VCO.

Health Benefits and Metabolic Effects of Coconut Oil

Several studies have investigated the health benefits of coconut oil, particularly its impact on metabolic parameters and weight management. For instance, a randomized controlled trial found that daily intake of extra virgin coconut oil increased HDL cholesterol and decreased the TC/HDL cholesterol ratio in men with obesity, suggesting a potential cardioprotective effect1. Another study demonstrated that VCO supplementation in mice fed a high-refined carbohydrate diet reduced adiposity, improved glucose tolerance, and lowered inflammatory markers, indicating its potential to mitigate obesity-related metabolic dysfunctions2.

Cognitive and Neurological Implications

Coconut oil has also been explored for its effects on cognitive function, particularly in the context of neurodegenerative diseases like Alzheimer’s. A study conducted in Sri Lanka found that VCO supplementation improved cognitive scores in APOE ε4 carriers with mild-to-moderate Alzheimer’s disease, although no significant differences were observed in the overall population8. Another pilot study suggested that a coconut oil-enriched Mediterranean diet could enhance cognitive functions such as memory and temporal orientation in Alzheimer’s patients, with more pronounced effects in women10.

Controversies and Considerations

Despite its potential benefits, coconut oil consumption remains controversial due to its high saturated fat content. Some studies have reported adverse effects, such as increased body weight and adiposity in healthy adults5, and hypothalamic inflammation and behavioral dysfunction in mice4. Additionally, a clinical trial found no significant antihypertensive effects of coconut oil supplementation in stage-1 hypertensive patients, challenging its purported cardiovascular benefits9.

Adverse Effects of Coconut Oil

Metabolic and Inflammatory Effects

Weight Gain and Adiposity: Coconut oil supplementation has been associated with increased body weight gain and fat mass in both mice and rats1 2 6.

Inflammation: Coconut oil can induce hypothalamic inflammation and increase the expression of pro-inflammatory cytokines such as TNF-α and IL-6 in various tissues, including the hypothalamus, adipose tissue, and liver1.

Metabolic Damage: Coconut oil consumption has been linked to metabolic disturbances, including increased levels of inflammatory markers and changes in glucose homeostasis1 10.

Behavioral and Psychological Effects

Anxiety: Studies have shown that coconut oil can induce anxious behavior in animal models1 2.

Mood Changes: In humans, coconut oil consumption has been associated with decreased perceived energy levels and increased feelings of sadness6.

Cardiovascular Effects

Cholesterol Levels: Coconut oil can increase total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels. While HDL is generally considered “good” cholesterol, the increase in total cholesterol and LDL can be concerning4 5 6 8.

Cardiometabolic Risk: Despite some beneficial effects on triglycerides and fasting blood sugar, coconut oil can elevate total cholesterol and LDL, which are risk factors for cardiovascular diseases8.

Bone Health

Impaired Bone Formation: Coconut oil supplementation has been shown to impair bone formation, as evidenced by shorter femur length in animal studies2.

Gastrointestinal Effects

Diarrhea: Mild gastrointestinal issues such as diarrhea have been reported in some human studies4.

How has Coconut Oil Improved Patient Outcomes?

Cardiometabolic Health

Dyslipidemia: Adding virgin coconut oil (VCO) to atorvastatin therapy significantly increased HDL levels and improved cardiovascular risk indices and oxidative stress markers in patients with dyslipidemia1.

Multiple Sclerosis (MS): Coconut oil, combined with epigallocatechin gallate (EGCG), reduced triglyceride levels and improved functional disability in MS patients2.

Cognitive Function

Alzheimer’s Disease (AD): A coconut oil-enriched Mediterranean diet improved episodic, temporal orientation, and semantic memory in AD patients, with more pronounced effects in women and those with mild-to-moderate disease3. Another study found that VCO improved cognitive scores in APOE ε4 carriers with mild-to-moderate AD10.

Oral Health

Gingivitis: Coconut oil pulling significantly reduced plaque formation and gingivitis, showing a more substantial decrease in plaque and bleeding indices compared to the control group4.

Quality of Life

Breast Cancer: VCO supplementation during chemotherapy improved the quality of life, functional status, and reduced symptoms like fatigue, dyspnea, and loss of appetite in breast cancer patients5.

Acute Poisoning

Aluminum Phosphide Poisoning: Coconut oil, especially when combined with Coenzyme Q10, showed cardioprotective effects, improving clinical, laboratory, and ECG parameters, and reducing the need for mechanical ventilation in ALP poisoning cases6 8.

Neurological and Functional Improvements

Multiple Sclerosis: Coconut oil and EGCG improved gait speed, balance, and muscle strength in MS patients, although the perceived balance did not change significantly7. Additionally, this combination reduced IL-6 levels, anxiety, and improved functional capacity9.

Coconut Oil Mechanisms of Action

Inflammatory Pathways

TLR4-Mediated Inflammation: CO activates inflammatory pathways through the TLR4 receptor, leading to increased expression of cytokines and inflammatory markers such as TNF-α and IL-6 in tissues like the hypothalamus and liver1.

NF-κB Signaling: CO consumption results in the migration of NF-κB to the nucleus, promoting the expression of pro-inflammatory genes. This effect can be mitigated by inhibiting TLR41 8.

Antioxidant and Anti-Inflammatory Properties

Antioxidant Activity: Virgin coconut oil (VCO) enhances antioxidant levels, including glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT), while reducing oxidative stress markers like malondialdehyde (MDA)2 5 6.

Anti-Inflammatory Effects: VCO reduces inflammation by modulating the TLR/NF-κB signaling pathway, decreasing the production of pro-inflammatory cytokines and mediators such as TNF-α and IL-68.

Metabolic Effects

Lipid Profile Improvement: CO can increase HDL cholesterol levels and decrease the TC/HDL cholesterol ratio, contributing to improved lipid profiles in individuals with obesity4.

Weight Management: VCO supplementation has been shown to reduce adiposity and improve glucose tolerance, serum glucose, and lipid levels, indicating its potential in managing obesity and related metabolic dysfunctions10.

Gastro-Protective Mechanisms

Ulcer Prevention: VCO exhibits gastro-protective effects by increasing gastric mucus content, reducing gastric juice volume and acidity, and enhancing antioxidant levels in gastric tissues. This helps in preventing ulcers induced by various stressors2.

Neuroprotective Effects

Memory Enhancement: VCO improves cognitive functions by increasing cholinergic activity and antioxidant levels while reducing oxidative stress in the brain. This is particularly beneficial in models of Alzheimer’s disease and high-fat diet-induced cognitive impairment5 6.

Endocrine Regulation

PCOS Management: VCO, in combination with clomiphene, helps in regulating endocrine functions by reducing hyperandrogenism and oxidative inflammation in polycystic ovarian syndrome (PCOS) models9.
