seed oil damage
Seed oils have gradually made their way onto nearly every shelf in the grocery store as well as into most restaurant dishes and fast foods. Today, it’s reached the point where seed oils make up ~10% of the average American’s caloric intake. The growth of seed oil usage has maintained a strong correlation with the rise in obesity in the United States.
The first thing to understand is that seed oils are high in unsaturated fats.
Unsaturated fats are chemically reactive
Unsaturated fats, as opposed to saturated fats (like butter and tallow), have double bonds in their fatty acid chains.
Double bonds are an issue because they are chemically reactive.
When exposed to heat, UV light, or air (i.e., the anytime you cook something or simply step outside), these double bonds oxidize, forming lipid peroxides which eventually break down into free radicals.
Free radicals are molecules with unpaired electrons that stabilize themselves by stealing electrons from other molecules, such as lipids, proteins, and even DNA
When free radicals steal electrons from other molecules, they create new free radicals in the process, setting off a chain reaction of molecular carnage as they all steal electrons from each other to stabilize themselves. This is known as oxidative stress.
Free Radicals cause oxidative stress
Cell Membrane Damage – Free radicals attack lipids in cell membranes, hindering cell integrity leading to cell dysfunction or death.
DNA Damage – Free radicals cause breaks and mutations in DNA, potentially leading to cancer and other genetic disorders.
Protein Damage – Free radicals modify proteins, disrupting their function and normal cellular processes.
Inflammation – Oxidative stress triggers inflammation, linked to diseases like heart disease, arthritis, and autoimmune conditions.
Increased Aging – Oxidative damage over time contributes to aging and diseases like Alzheimer's and Parkinson's
Polyunsaturated fats (PUFAs) produce the most free radicals
Seed oils specifically are high in polyunsaturated fats (PUFAs) meaning fats that have more than one double bond in their chain, whereas monounsaturated fats in oils from things like olives and avocados only have one.
Monounsaturated fats (MUFAs) also produce free radicals
Monounsaturated fats are generally more stable than PUFAs, however there’s still a chance they can produce free radicals when heated. Olive Oil, Avocado Oil, Pecan Oil, Macadamia nut Oil, Sesame Oil are all MUFA's.
Saturated fats (SFAs) unlikely to produce free radicals
On the other hand, in saturated fats, all carbon atoms are “saturated” with hydrogen atoms.
This means they have no double bonds, and thus a far smaller chance of producing free radicals – even at high temps.
This is why you want to opt for saturated fats like butter, beef tallow, or coconut oil for cooking or frying.
Omega 6 causes massive inflamamation
The other issue with seed oils is their Omega 6 content.
Omega 6 and Omega 3 fatty acids are both essential for health, however, they must be consumed in a balanced ratio (~1:1). PUFAs in seed oils are extremely high in omega 6 which, when consumed without a proper amount of omega 3s, creates massive inflammation in the body.
This inflammation in the body is where you start to get metabolic and cardiovascular issues that result in that excessive weight gain, plaque buildup, blood clotting, heart disease, and a lot of the same issues mentioned earlier. Because seed oils are in everything these days, the average American is consuming an omega 6 to omega 3 ratio of ~15:1… Not ideal.
Processing creates free radicals
To make matters even worse, the processing methods they use to produce seed oils are downright diabolical in their own regard. When seeds are harvested, they’re first heated to extremely high temps (oxidizing PUFAs and creating free radicals), then they’re treated with chemical solvents like hexane, and finally are bleached and deodorized to improve shelf life.
Free radicals and omega 6 content aside, after a process like this, there is absolutely nothing natural about the resulting substance. Take the sum all these things and it’s probably more accurate to classify seed oils as a bioweapon rather than a food.
How to Avoid Seed Oils
The best way to avoid seed oils is to simply cook your own food. Always use saturated fats like butter, tallow, and coconut oil for cooking at high heat, and olive oil or avocado oil as toppings without cooking.
ai questions (llama3.1)
>>> explain lipid peroxides
Lipid peroxides are a type of reactive oxygen species (ROS) that play a crucial role in cellular signaling and homeostasis.
What are lipid peroxides?
Lipid peroxides, also known as lipid radicals or aldehydes, are unstable molecules formed when an alkyl group (a carbon chain) is removed from a fatty acid or phospholipid molecule. This process is initiated by the presence of free radicals, which are highly reactive molecules that can damage cellular components.
Formation of lipid peroxides
Lipid peroxides are formed through a series of oxidation reactions involving fatty acids and other lipids. These reactions involve the transfer of electrons from one molecule to another, resulting in the formation of highly reactive species, such as:
-
Lysyl radical: A free radical formed when an electron is removed from a lysine residue on a protein.
-
Alkylperoxyl radical: A lipid peroxide formed when a fatty acid or phospholipid molecule loses an alkyl group and gains an oxygen atom.
Role of lipid peroxides in cellular signaling
Lipid peroxides play a crucial role in cellular signaling pathways, including:
-
Protein kinase C (PKC) activation: Lipid peroxides can activate PKC, a key enzyme involved in cell signaling.
-
Inflammation and immune response: Lipid peroxides are produced during the inflammatory process, where they serve as signaling molecules to recruit immune cells.
-
Cell death and survival: Lipid peroxides can induce apoptosis (programmed cell death) or promote cellular survival, depending on their concentration and context.
Diseases associated with lipid peroxide imbalance
An imbalance of lipid peroxides in the body has been linked to various diseases, including:
-
Atherosclerosis: A condition characterized by the buildup of fatty plaques in arteries.
-
Alzheimer's disease: Lipid peroxide accumulation may contribute to the progression of Alzheimer's disease.
-
Oxidative stress: Lipid peroxides can cause oxidative stress, leading to damage to cellular components.
Antioxidants and lipid peroxides
Antioxidants, such as vitamins C and E, beta-carotene, and polyphenols, can neutralize lipid peroxides by donating an electron or forming a stable compound with the free radical. This process helps maintain redox balance and prevents oxidative stress.
In summary, lipid peroxides are highly reactive molecules formed through oxidation reactions involving fatty acids and other lipids. They play a crucial role in cellular signaling pathways and have been implicated in various diseases associated with oxidative stress and inflammation.
>>> what is the role of aspirin in reducing free radicals
Aspirin, also known as acetylsalicylic acid (ASA), has been found to have a unique property: it can scavenge and neutralize free radicals, thereby playing a role in reducing oxidative stress.
Mechanism of action
Aspirin's ability to reduce free radicals is primarily due to its chemical structure. Aspirin contains an acetyl group (-COCH3), which is responsible for its antioxidant properties. When aspirin interacts with free radicals, the acetyl group donates a hydrogen atom (H-) and forms a stable compound that neutralizes the radical.
Antioxidant properties
Aspirin has been shown to exhibit antioxidant properties through various studies:
-
Free radical scavenging: Aspirin can scavenge hydroxyl radicals (•OH), which are highly reactive free radicals.
-
Inhibition of lipid peroxidation: Aspirin can inhibit the oxidation of lipids, thereby reducing oxidative stress.
-
Antioxidant enzyme activation: Aspirin can activate antioxidant enzymes like superoxide dismutase (SOD) and catalase, which help to neutralize free radicals.
Role in reducing oxidative stress
Aspirin's ability to reduce oxidative stress has been implicated in various diseases, including:
-
Cardiovascular disease: Reduced oxidative stress may contribute to the protective effects of aspirin on cardiovascular health.
-
Neurodegenerative diseases: Aspirin may help to reduce oxidative stress associated with neurodegenerative diseases like Alzheimer's and Parkinson's.
Important notes
While aspirin does have antioxidant properties, it is essential to note that:
-
Dose matters: The dose of aspirin required to achieve antioxidant effects can be high, and excessive intake can lead to adverse effects.
-
Individual variability: Aspirin's effectiveness in reducing free radicals may vary between individuals due to genetic differences or other factors.
