Not just vitamins: what beneficial compounds are found in vegetable oils | Health benefits of cold-pressed oils

Vegetable oils are an essential part of a healthy, balanced diet, providing up to one-third of total daily caloric intake. Traditionally used in cooking, they are now increasingly popular in naturopathy, herbal medicine, and even DIY skincare. That growing interest is easy to explain: cold-pressed plant oils have an exceptionally rich biochemical composition and contain far more than just vitamins.

Corn, sunflower, olive, flaxseed, camelina, and many other oils contain vitamins A, E, D, and B-group vitamins. Each plays a role in metabolic processes and is vital for the proper functioning of the human body. However, vitamins are only part of the story. Plant-based fats also contain a wide range of minerals and biologically active compounds.

Beneficial components of vegetable oils

Raw (unrefined) oils contain:

• Phospholipids (phosphatides) – structural components of cell membranes that support the skin’s barrier function and participate in most metabolic processes. They are also essential for hepatocyte (liver cell) regeneration;
• Sterols (phytosterols) – plant analogues of cholesterol that help slow the conversion of «good» cholesterol into «bad», reducing the risk of atherosclerosis and other cardiovascular diseases;
• Pigments (carotenoids, chlorophyll) – powerful antioxidants that protect the body from free radicals and help slow age-related degenerative processes;
• Trace elements (magnesium, phosphorus, iron, etc.) – regulate metabolism and are necessary for enzyme production, neurotransmitter synthesis, and blood formation;
• Natural waxes (in residual amounts) – form a protective barrier on the skin, preventing dehydration, dryness, loss of elasticity, and premature aging;
• Polyphenols – plant compounds with strong anti-inflammatory and antioxidant properties that also support nervous system function;
• Fatty acids (omega-3, omega-6, omega-9) – essential fatty acids that are not produced by the human body but are crucial for cell membrane structure, sebum production, and the proper functioning of the nervous, cardiovascular, immune, and other systems;

Some plant-based oils also contain esters — highly active organic compounds with broad effects. They may act as antiseptics, have calming or stimulating properties, promote vasodilation, and help relax muscles (including smooth muscle tissue).

It is incorrect to claim that one vegetable oil is universally healthier than another. Each oil offers a unique combination of nutrients essential for human health.

The most valuable are fresh, raw, cold-pressed oils made from eco-friendly nuts, seeds, grains, or fruit pulp. These can even be produced at home using a specialized oil press, a press barrel, and high-quality raw materials.
