Three things to remember
- Prefer unsaturated fats in place of some saturated fat.
- All oils are energy-dense, including premium and cold-pressed oils.
- Fish-oil weight and EPA+DHA content are different label numbers.
Get to know the types
Fat helps provide essential fatty acids and supports absorption of fat-soluble vitamins. It supplies about 9 kcal per gram, compared with about 4 kcal per gram for protein and carbohydrate.

| Type | Where you find it | How to think about it |
|---|---|---|
| Unsaturated fats ↗ | Nuts, seeds, fish and many plant oils | Use these in place of some saturated-fat sources. |
| Saturated fats ↗ | Ghee, butter, fatty meats, coconut and palm oils | Limit the overall amount; plant origin does not mean low saturated fat. |
| Trans fats ↗ | Some partially hydrogenated fats and foods made with them | Avoid industrially produced trans fats. |

General guidance—not a personal macro plan
WHO recommends keeping saturated fat at no more than 10% and trans fat at no more than 1% of total energy, replacing them with healthier sources. It advises adults to limit total fat to 30% of energy or less to help prevent unhealthy weight gain. These are population guidelines; individual needs can differ.
At an illustrative 2,000 kcal intake, 10% of energy is about 22 g saturated fat. Count the whole diet rather than treating this as a cooking-oil allowance.
Essential fatty acids
Linoleic acid (omega-6) and alpha-linolenic acid, or ALA (omega-3), must come from the diet. The body makes other fatty acids. EPA and DHA have separate roles and ALA conversion is limited; the three omega-3 names are not interchangeable.
ALA, EPA and DHA are not identical
ALA is an essential omega-3 found in foods such as flaxseed, chia and walnuts. EPA and DHA are found in fish and seafood; algal oils can provide a non-fish option. The body converts only small amounts of ALA into EPA and DHA.
A bottle containing “1,000 mg fish oil” does not necessarily contain 1,000 mg EPA+DHA. Check each listed amount, servings and capsule count. A suitable dose depends on the reason for using it; there is no universal fish-oil prescription for every shopper.

Choose for everyday use
- Use a measured amount of oil and consider fats already present in the meal.
- Compare saturated fat on the label, not just premium words such as organic or cold-pressed.
- Choose an edible cooking oil for food use. A beauty or external-use oil is not interchangeable.
- For omega-3 products, check the actual EPA/DHA content, source and any other added nutrients.

Before adding a high-dose supplement
Ask your clinician or pharmacist about omega-3 supplements if you take anticoagulants or have a planned procedure. Treatment for high triglycerides is a medical decision; a retail supplement is not automatically equivalent to a prescribed product.

Common questions
Is coconut oil automatically healthier because it comes from a plant?
No. Coconut oil is high in saturated fat. Compare its role and quantity within your whole diet rather than relying on plant-based branding.
Can I eat unlimited nuts or oil because the fats are healthier?
No. Foods rich in unsaturated fat still contribute energy. Portions and the rest of the diet matter.
