5 Types of oil that are classified as unhealthy for cooking

Oil is one of the richest sources of fat. Some types of oil can even lower cholesterol and maintain a healthy heart. However, please note that not all oils are healthy enough to use for cooking. There are several types of oil that should be limited because the risks to health are quite large.

Unhealthy variety of oil for cooking

Olive oil, canola oil, and sesame oil are some examples of the most recommended oils for cooking. This is because all three contain unsaturated fatty acids which nourish the heart and blood circulation.

On the other hand, there are also types of oil whose use needs to be limited. Here are a few examples:

1. Hydrogenated oil

Hydrogenation is the process of converting liquid fat (oil) into solid fat by adding hydrogen. This process produces the product in the form of partially hydrogenated oil, often known as trans fat.

Although contained naturally in several foodstuffs, oil is often found in junk food it is not classified as healthy for cooking.

The reason is, consumption of hydrogenated oil in large quantities can increase bad cholesterol and trigger the formation of plaque that clogs blood vessels.

2. Coconut oil (coconut oil)

Consumption of coconut oil, one of which is for cooking, is still a controversy until now.

Although not entirely bad for health, these oils contain medium-chain fatty acids which make them difficult to convert into energy stores.

Kimberly Gomer, MS, RD, head of nutrition at Pritikin Longevity Center in the United States, urges people with high cholesterol to avoid coconut oil.

For owners of normal cholesterol, consumption of coconut oil is still allowed but needs to be limited.

3. Palm oil (Palm oil)

Palm oil actually has ingredients that are beneficial for brain health.

However, the high saturated fat content makes this oil not healthy enough to cook. Especially for people with heart disease, stroke, or high cholesterol.

Studies in journals Lipid Health and Disease found that consumption of palm oil can increase bad cholesterol, especially cholesterol which has large particles

This cholesterol can trigger plaque formation in blood vessels more quickly.

4. Oil from animal fats

Oil from animal fats are better options than trans fats.

However, animal fats are also rich in saturated fats like palm oil. This saturated fat content can even reach 40 percent of the total nutrition.

Saturated fat can increase bad cholesterol and lower good cholesterol.

The impact, cholesterol plaque is easier to form and clog blood vessels. This then makes oil from animal fats classified as unhealthy for cooking.

5. Vegetable oil

The term vegetable oil usually refers to oil made from a mixture of several other oils.

Since the exact content is not known, you cannot be sure whether vegetable oil contains saturated or unsaturated fats.

In addition, certain oils contained in vegetable oils can have low smoke points. That is, this oil is flammable at lower temperatures.

Flammable oils can produce carcinogens that increase the risk of cancer.

There is no oil that is really "bad" or classified as unhealthy and should not be consumed at all. Unless you have heart disease or high cholesterol.

In these conditions, try to choose an alternative to oil that is more friendly to health.

Also, use healthier processing techniques such as sauteing, and avoid methods deep-frying which can deplete food nutrients.
