Canola Oil Nutrition Value

Canola oil is a popular cooking oil that is often considered a healthy option because of its low levels of saturated fat and cholesterol. It is composed mainly of unsaturated fats, including oleic acid (61%), linoleic acid (21%), and alpha-linolenic acid (11%). In addition, canola oil also contains small amounts of sterols (0.53-0.97%) and tocopherols (700-1200 ppm), which are plant compounds that may have health benefits.

One of the key benefits of canola oil is that it is low in saturated fat, which is linked to an increased risk of heart disease. It is also a good source of polyunsaturated fats, including omega-3 and omega-6 fatty acids, which are essential for maintaining healthy cells and tissues. Overall, canola oil is a nutritious and versatile cooking oil that can be a healthy choice for those looking to incorporate more unsaturated fats into their diet.

One of the potential health benefits of canola oil is its ability to help lower cholesterol levels. This is partly due to its high content of plant sterols, which are useful for the absorption of cholesterol in the body, leading to a reduction of up to 10-15%. In addition, canola oil is also rich in mono-unsaturated fats (MUFA), which have been shown to help lower levels of LDL or "bad" cholesterol while promoting the production of HDL or "good" cholesterol. Consuming canola oil may help support a healthy lipid profile, potentially reducing the risk of heart disease and other conditions related to high cholesterol.

Beneficial in reducing inflammation

Canola oil has been shown to have anti-inflammatory effects, which may be beneficial for individuals with certain health conditions. For example, research has shown that consuming canola oil may help reduce joint tenderness and stiffness associated with acute arthritis. In addition, canola oil may also have a protective effect against inflammation related to asthma and bowel disorders, making it a potential anti-inflammatory agent.

It can be used as a moisturizer

Canola oil can be used as a natural moisturizer for skin care due to its high content of vitamins E and K. These nutrients help improve the skin's appearance by reducing the appearance of fine lines, wrinkles, acne, and other blemishes. Vitamin E, in particular, is known for its antioxidant properties, which may help protect the skin from the damaging effects of free radicals.

To use canola oil as a moisturizer, apply a small amount to clean the dry skin and massage it until it is fully absorbed. This can help to keep the skin feeling soft, smooth, and hydrated and may also help to increase the healing rate of injuries and slow down the appearance of wrinkles. However, it is important to note that canola oil should be used in moderation and may not be suitable for all skin types, so it is always a good idea to test a small patch of skin.

Boosts energy levels

Canola oil helps boost energy levels due to its low cholesterol content and high levels of antioxidants. These nutrients may help support the body's metabolism, allowing it to function more efficiently and effectively. As a result, the body may not become sluggish, and energy levels may be less likely to be sapped by slow circulation or an overworked cardiovascular system.

It helps reduce cancer risk

The use of canola oil has been linked to a reduced risk of cancer due to its high content of antioxidants, particularly vitamin E. These nutrients work to combat harmful free radicals, which can cause healthy cells to mutate into cancerous cells. By reducing the number of free radicals in the body, canola oil may help to lower the risk of contracting cancer. Additionally, if an individual is already affected by cancer cells, the antioxidants in canola oil may help to slow down their multiplication and spread, potentially aiding in cancer treatment.

It improves memory and enhances cognitive function

In addition to its potential cancer-fighting properties, canola oil may also positively affect memory and brain function. The antioxidants in canola oil may help to protect the brain from damage caused due to free radicals, potentially reducing the risk of developing conditions such as Alzheimer's disease and dementia

Used for haircare

Canola oil may also be used as a natural hair care treatment to address issues such as dryness, breakage, frizz, and split ends. In addition, it helps to improve the quality of tresses and is also effective at reducing dandruff and making hair more manageable. To use canola oil for hair care, apply a small amount to the hair and scalp, massaging it in gently. It may be left on for a few hours or overnight before being washed out with shampoo.

Canola Oil Benefits for Hair and Skin

Canola oil benefits for hair and skin are explained by its antioxidant, anti-inflammatory, antibacterial properties. The presence of vitamins E, C and K in it also help. With it, you can

  • Delay skin aging
  • Prevent acne
  • Improve the skin texture
  • Prevent skin infections

Why Is Canola Oil Harmful for Your Health?

  • It is made by genetic modification

Canola is genetically modified to increase its tolerance towards pests and herbicides. Despite being termed safe for consumption, there are concerns about its potential harm. People avoid using GMO food because there aren’t enough results on the impact it has on one’s health.

  • It is a highly refined oil

This oil extraction requires the use of chemicals, high heat, bleaching, and deodorizing. The extensive refining process causes the oil to lose some of its natural benefits like:

  • Vitamins
  • Antioxidants
  • Fatty acids
  • It has a high number of omega 6 fats

While omega 6 fat is essential for your body, having it in excess has a number of side effects. The ratio of omega 6 and omega 3 fatty acids in this oil is estimated to be 15:1 as opposed to the average healthy ratio of 1:1. This imbalance can result in
