How Much Cooking Oil Do We Really Need? – Common Myths About Edible Oils, Healthy Oil Consumption and the Truth About Palm Oil

We have never had more choices of cooking oils than we have today. Coconut oil. Sesame oil. Rice bran oil. Sunflower oil. Soybean oil. Groundnut oil. Olive oil. Palm oil. And with every new oil comes a new health claim.

One oil is called “heart-healthy.” Another is said to be “bad for cholesterol.” Some people believe that completely avoiding oil is the healthiest choice. Others believe that certain traditional oils can be consumed without restriction.

So what is the truth?

Perhaps the more important question is not “Which oil is the healthiest?”

It is:

How much oil does the human body actually need, and how should we choose and use it?

Oil is not the enemy

Dietary fat is an essential part of human nutrition. The body needs fat for energy, cell function and absorption of fat-soluble vitamins. Some fatty acids, including linoleic acid and alpha-linolenic acid, must come from the diet. The problem is not simply the presence of fat.

The problem is excessive intake, the type of fat, and the overall dietary pattern.

WHO recommends that adults generally keep total fat intake to around 30% or less of total daily energy intake. It also recommends limiting saturated fat to less than 10% of energy and trans fat to less than 1%, while favouring unsaturated fats.

This gives us an important principle:

We need fat. We do not need unlimited fat.

So, how much cooking oil is good per day?

There is no single number that is appropriate for every adult.

Oil requirement depends on:

• Total calorie requirement
• Age and body size
• Physical activity
• Other sources of dietary fat
• Cooking methods
• Overall dietary pattern
• Individual health conditions

A person who eats nuts, seeds, dairy, fish, meat or other foods containing fat is already consuming dietary fat beyond the oil added during cooking.

Therefore, simply measuring the oil poured into the cooking pan does not tell the whole story.

As a practical reference, the American Heart Association lists 2–3 servings of fats or oils per day, equivalent to about 9 teaspoons, but this is a dietary guideline rather than a universal prescription for every individual.

For most households, therefore, the better approach is: Use oil in moderation, measure it rather than pouring it freely, and consider all sources of fat in the day’s diet.

The goal should not be to eliminate oil. The goal should be to avoid unnecessary excess.

Common Myths About Cooking Oil

Myth 1: “Oil should be completely eliminated from the diet.”

Not true.

Dietary fats have important physiological functions. The issue is choosing appropriate sources and quantities.

Completely eliminating visible oil is not necessary for a healthy diet. Instead, total dietary fat and the balance between saturated and unsaturated fats should be considered.

Myth 2: “If an oil is expensive, it must be healthier.”

Not necessarily.

Price is influenced by the crop, availability, extraction process, refining, transportation, imports, packaging and commodity-market conditions.

A higher price does not automatically mean a better nutritional profile. The nutritional composition of the oil and the quantity consumed matter more than the price tag.

Myth 3: “Cold-pressed or unrefined means unlimited health benefits.”

Not necessarily.

Processing affects an oil’s characteristics, stability, flavour and minor components. But “natural,” “cold-pressed” or “unrefined” does not mean that the oil can be consumed without quantity considerations.

Calories still count. Fat composition still matters.

Myth 4: “All vegetable oils are healthy.”

This is an oversimplification.

“Vegetable oil” describes the source, not a single nutritional composition.

Different vegetable oils contain different proportions of saturated, monounsaturated and polyunsaturated fatty acids.

Soybean, sunflower, sesame, rice bran, coconut and palm oils are not nutritionally identical.

Therefore, the term vegetable oil alone is not enough to judge an oil.

Myth 5: “Palm oil is poisonous.”

No.

Palm oil is an edible vegetable oil and is widely used in food processing and cooking.

However, that does not make it nutritionally equivalent to oils that are lower in saturated fat.

Palm oil contains a relatively high proportion of saturated fatty acids. WHO identifies palm oil among sources of saturated fat, while the American Heart Association recommends replacing saturated fats with unsaturated fats where possible.

So the scientifically responsible answer is neither “palm oil is poison” nor “palm oil is a health oil.”

It is:

Palm oil is an edible oil that can be used as part of a diet, but its relatively high saturated-fat content means that quantity and the overall dietary pattern matter.

Palm Oil: Good or Bad?

This is perhaps the most debated question in the edible-oil industry. The answer is more complicated than a simple good/bad classification.

What makes palm oil attractive?

Palm oil has important technological and commercial advantages. It is relatively stable, has useful functional properties and is widely used in food manufacturing, frying and processed foods. Palm oil and palmolein are therefore important ingredients in the global food and edible-oil industry.

From an industrial perspective, these characteristics matter. From a nutritional perspective, however, its relatively high saturated-fat content deserves consideration.

The American Heart Association identifies palm and coconut oils as tropical oils with more saturated fat than many non-tropical liquid vegetable oils. It recommends choosing oils richer in mono- and polyunsaturated fats when replacing saturated fats.

Therefore:

Palm oil is not automatically “bad.”

But if the objective is to reduce saturated-fat intake, regularly replacing palm oil with an oil richer in unsaturated fats can be a sensible choice.

Should We Rotate or Mix Cooking Oils?

For many Indian households, using different oils in moderation can be a practical approach.

Different oils have different fatty-acid profiles and culinary characteristics.

For example:

• Sesame oil brings its distinctive flavour and traditional culinary role.
• Coconut oil is closely associated with Kerala and South Indian cooking.
• Sunflower and soybean oils are relatively rich in polyunsaturated fats.
• Rice bran oil provides a different fatty-acid profile and contains minor components such as oryzanol.
• Palmolein has useful functional properties in frying and food applications.

Rather than searching for a single “perfect oil,” the more useful approach is to consider variety, quantity, cooking method and the rest of the diet.

What Does “Healthy Oil Consumption” Really Mean?

A healthy approach to edible oils can be reduced to a few simple principles:

1. Use oil in moderation

2. Look at the type of fat

Prefer unsaturated fats more often 

3. Don’t judge oil by price

Expensive does not automatically mean healthier.

4. Don’t judge oil by marketing language

“Natural,” “premium,” “traditional,” “cold pressed” or “refined” should not replace nutritional evaluation.

5. Avoid repeated frying and reheating

6. Consider the complete diet

7. Choose the oil according to the application

The best oil for a salad dressing need not be the best choice for every cooking or food-processing application.

From the Kitchen to the Processing Plant

There is another side to this discussion that is particularly relevant to us at Plant Technologies International. Before an edible oil reaches the kitchen shelf, it passes through an extensive processing chain. It is the result of an engineered process designed to convert an agricultural raw material into a consistent, safe and usable food product.

This is where process engineering, equipment selection, instrumentation, automation and quality control become critical.

The Bottom Line

There is no magic number of teaspoons that can be prescribed to every human being.

There is also no single edible oil that can be declared universally “the healthiest.”

The better question is:

How much fat does my overall diet provide, what type of fat am I consuming, and how am I using the oil?

And when it comes to palm oil, the answer should be equally balanced.

Palm oil is an edible vegetable oil, not a poison. But it is relatively high in saturated fat, so moderation and the overall dietary pattern matter.

The real objective should not be “zero oil.” It should be:

The right oil. The right quantity. The right application.

At Plant Technologies International, we look at edible oils from another perspective: how technology, equipment and process engineering transform oilseeds into high-quality edible oils.

From extraction to refining, from equipment to process control, the journey from seed to bottle is an engineering journey.

From Seed to Oil. From Process to Product. From Plant to Value.

Plant Technologies International supports edible-oil processing requirements with plant equipment, spares, accessories and process-related solutions for soybean, rice bran, sesame, sunflower and other vegetable oils.
