However, oil is necessary.

The discussion was about avoiding dangerous oils, but that doesn't mean "just eliminate oil.

In both beauty and health, oil is essential. For example, in skincare, after applying a moisturizing lotion, we use creams, lotions, or beauty oils to prevent moisture from evaporating. Similarly, beauty oils contain nutrients that can lead to beautiful skin if used correctly. The same principle applies to our body and brain.

What specific benefits does oil provide for our bodies?

1. Prevents Aging
   Plant oils are rich in vitamin E. UV rays and food additives can accelerate aging. While UV exposure is necessary in moderation, sunscreen is essential during sunbathing. Vitamin E is effective for anti-aging. While dangerous oils were mentioned, safflower oil and sunflower oil are high in vitamin E. The problem is not with linoleic acid itself (or omega-6), but rather with excessive intake. Linoleic acid is necessary for the body, so if you follow the recommended intake, these oils can be quite beneficial.Vitamin E protects cell membranes from oxidative stress and helps prevent the increase of peroxidized lipids, which contributes to anti-aging. It also promotes blood circulation, which is beneficial for people with cold extremities. Additionally, it helps regulate the pituitary gland and adrenal function, supporting hormone balance—beneficial for women.

   Oil also prevents moisture loss during cooking. Vitamins in vegetables like cabbage and carrots can be lost simply by washing them. Therefore, cooking them in the microwave is good, but another method is to sauté them with oil. Oil can coat the surface of vegetables, preventing vitamin loss. Sautéing carrots with oil is highly recommended, as it's both delicious and convenient compared to other methods.

2. A Strong Ally for Weight Loss
   Oil often has a negative image when it comes to dieting. However, moderate oil intake can improve satiety, and the oleic acid found in healthy oils gently stimulates the intestines, aiding in regular bowel movements. The idea is like coating the intestinal surface with lotion. Not all oil turns into fat or excess weight. Alpha-linolenic acid, in particular, is used preferentially for energy in the body, making it a good option for those on a diet. Of course, excessive intake of anything can be harmful, so moderation is key.
3. Promotes Healthy Skin
   Using oil for beauty has been a common practice throughout history and is widely accepted today. Good quality oil can benefit the skin both when ingested and applied topically. Oils contain vitamins and anti-inflammatory components like alpha-linolenic acid, which help heal damaged skin. Oleic acid helps active ingredients penetrate the skin, acting as a natural "delivery agent." Carrier oils, which transport beauty ingredients into the deeper layers of the skin, are examples of this. They also prevent moisture loss. Ceramides contain linoleic acid, which helps maintain healthy skin.
4. Allergy Prevention
   As explained with dangerous oils, while certain oils can contribute to allergies, others can help manage them. Linoleic acid can protect the body in appropriate amounts. Excessive intake and overheating, which leads to the formation of hydroxynonenal, can be harmful. Allergies are often due to an overactive immune response, attacking the body even after the harmful agents are gone. Therefore, incorporating alpha-linolenic acid to balance the omega-6 intake can help manage inflammation and immune response.
5. Suppresses Cholesterol Absorption
   Cholesterol is necessary for the body, but its balance is crucial. It is produced in the liver and is involved in creating cells and hormones, as well as nutrient absorption. The problem arises when there is an imbalance between LDL (bad) and HDL (good) cholesterol. Plant oils contain phytosterols that lower total cholesterol and LDL cholesterol. Phytosterols are similar to human cholesterol and can reduce overall cholesterol absorption. They are not utilized by the body, so they are excreted, leading to a reduction in excess cholesterol. Alpha-linolenic acid also helps lower LDL cholesterol, which can help prevent lifestyle-related diseases.
6. Benefits for Mental Health
   Women experience hormonal changes due to menstruation, childbirth, and breastfeeding. As previously explained, good oils support hormonal balance and brain health. The brain is composed of about 60% fat, and quality oils support its healthy function. Dangerous oils can negatively affect brain cells, but alpha-linolenic acid, DHA, and EPA are known for their positive effects on the brain. These omega-3 components help manage inflammation and support mental health, so focusing on omega-3s and reducing linoleic acid intake can be beneficial for mental care.
