The Good and The Bad Fats – What are They?

Many people think that all fat is bad. I don’t blame them for the misconception about fat because there is a lot of publicity about the negative effects of fat on health. The weight loss
industry is one of the culprits in concentrating mostly on the negative impact of fat and little is said about the positive effects of fat. In this article I will cover both the positive impact and negative effects of fat.

Think about it. Everyone has fat on them, however there is a certain amount of safe fat, and then there is excess fat. We need a certain percentage of fat to be healthy. Fat droplets inside most of our body’s cells regulate excess proteins in our bodies. A certain amount of fat is necessary for preserving the function of cells.”

“Fat droplets are microscopical fat spots present in almost all the cells in the body, and they play the role of warehouses or storage depots for a certain type of protein used by molecules to bind DNA. Besides storing the particular histone proteins needed by cells to bind and organize DNA in the nucleus, the fat droplets also serve as deposits for other proteins found in excessive amounts within our bodies. If these proteins were not gathered and stored somewhere in the body, they would become harmful for our health.”

Saturated Fats

The sources for these types of fats are mainly animals: butter, bacon, chicken skin, T-bone, etc. This is bad fat that causes high cholesterol and contributes to heart disease.

Trans-fatty acids

These type of fats are created by adding hydrogen to liquid fats to make them semi-solid and are used in some margarines and snack foods. They increase your risk of heart disease and are thought to be associated with obesity, cancer and diabetes.

Polyunsaturated Fats

Fish, sunflower and soya bean are some of the sources of polyunsaturated fats. These are good fats because they lower your chances of getting a heart disease. But not all polyunsaturated fats are equally good for you. For instance omega-6 fatty acids are polyunsaturated fats and better than saturated fats but are potentially inflammatory, but Omega-3 fatty acids found in fish are good in preventing heart disease. Though sunflower oil, is better for you than saturated fats, it is still a potential health hazard, especially in large quantities.

Monounsaturated Fats

These types of fats are found in nuts, avocado, olives, olive oil, peanut oil and canola. Olive oil or canola are better for cooking than polyunsaturated fats like sunflower oil because they are structurally more stable. Polyunsaturated are more likely to change into trans-fatty acids, the most detrimental fats, when heated. Olive oil is the best choice because it contains 70% of monounsaturated fats whereas canola contains about 50%. Olive oil also contains compounds that stabilise blood sugar and anti-oxidants that help protect against damaging free radicals.
