Margarine, made from vegetable shortening, was once seen as a healthier alternative to butter, but it can still increase the risk of heart disease due to high levels of trans and saturated fats. Some manufacturers have reduced these fats, but moderation is still advised.
As with any food that is essentially pure fat, there are still health concerns associated with margarine, especially when it’s consumed in large quantities. One of the biggest potential problems is the increased risk of heart disease. Many types contain high levels of saturated fat and dangerous trans fat, which are known to lower levels of the beneficial high-density lipoprotein (HDL) cholesterol and raise levels of the harmful type known as low-density lipoprotein (LDL) cholesterol. ).
Once butter was associated with health risks like heart disease due to its high levels of saturated fat and cholesterol, many people were looking for an alternative. Often people switch to margarine, which often has no cholesterol and at least lower levels of saturated fat than butter and often fewer calories. The reason there is no cholesterol is because margarine is made from solidified vegetable shortening instead of animal sources. As time went on, health professionals started noticing health issues like an increased risk of developing heart disease for people who also consumed margarine.
Researchers have found that the heart disease risk associated with margarine is due to the presence of trans fatty acids, also known as trans fats. These substances are formed in the solidification process of vegetable oil and have been linked to various health problems. Firm sticks have much higher levels of trans fat than softer spreads. Trans fats have been shown to have a negative effect on cholesterol levels, an important indicator of heart disease, even though margarine doesn’t actually contain any cholesterol. Trans fats lower the levels of good HDL cholesterol and increase the amount of harmful LDL cholesterol in the body.
Another contributing factor to the heart disease risk associated with margarine is the amount of saturated fat found in many brands. Although there is less saturated fat than butter, high levels can be present in some margarine products. The amounts of these unhealthy substances can vary widely depending on the manufacturer. As a rule, it’s a good idea for consumers to look for products with low levels of saturated fat and to remember to use them in moderation.
Many manufacturers have removed as much trans fat from their products as possible, and many types of margarine are now also made with unsaturated fats such as olive or canola oil. Products with reduced saturated fat and no trans fat are less harmful than others, but still should only be eaten in moderation. Consuming large amounts of any fatty food is likely to increase your chances of developing heart disease, but limiting your consumption to small amounts of unsaturated fat reduces this risk.
