What is margarine?

Margarine is a water-in-fat emulsion made from plant fats. Margarine can be used for cooking or baking. Margarine with 80% fat can be used as a butter substitute for butter in baking. Reduced or low-fat margarine is used as a spread for toasts, sandwiches, and crackers when cutting down on calories.

What is the difference between butter and margarine?

The difference lies in their composition. The source of fats for butter is animal-based. For margarine, the source of fat is vegan. Butter has a high percentage of cholesterol and saturated fats, therefore, it stays solid at room temperature. Margarine has more unsaturated fats that are healthy and stay liquid at room temperature. Higher water content and unsaturated fats are what make margarine prone to spoilage.

What are the different types of margarine?

Margarine can be categorized into the following three types.

Stick margarine

Stick margarine is solid at room temperature just like butter. It has high levels of trans fats due to the hydrogenation of vegetable fats. Stick margarine can be used for both cooking and baking. Use sparingly to avoid negative health effects.

Tub margarine

Tub margarine has a vegetable fat content of 61-79%. These have negligible trans fat content and are often fortified with calcium. These can be used for cooking. Due to a low-fat content, using them in baking makes a dry and tough crumb 

Low-fat margarine

Low-fat margarine has a vegetable fat content of 0-40%. These are suitable to be used as spreads. When used in baking, it results in a dense crumb structure of inferior quality.

Health benefits of using margarine

Margarine is rich in polyunsaturated fats and phytosterols. These are responsible for reducing the risk of heart diseases and LDL cholesterol, respectively.

Health risks of using margarine

Margarine is solidified to mimic the appearance and composition of butter. For this, vegetable oil is hydrogenated to convert the unsaturated fats into saturated fats. While doing so, high levels of trans fats are produced as a by-product.

Margarine is high in omega-6 fats. Omega-6 fats are pro-inflammatory and must be taken with omega-3 fats in a balanced proportion.
