Many of our common foods are processed foods, and some processed foods are less nutritious than the original whole foods from which they are made. Processed foods usually have sugar, salt, or fat added, and fiber is taken out of them. It's healthier to try to substitute the less processed foods instead of eating the more processed ones. Let's look at some examples!


Fried Foods

French fries, Instant noodles

Potatoes, vermicelli, and noodles are rich sources of carbohydrate. Normally, these should belong to the "grain" group in the Healthy Diet Pyramid. However, when foods get deep-fried, additional calories from oil are added as well to the original food calories. For example, the total calories of French fries not only come from the calories of potatoes, but also the calories from oil; therefore, French fries belong to "Fat, Sugar and Salt" layer but not the "Grain" layer. Also, for instant noodles, after they are deep-fried, they may no longer be in the bottom "Grain" layer, but may be considered to be on the top of the "Fat, Sugar and Salt" layer.

Deep-fried drumstick, chicken wings

Chicken wings and chicken legs are rich sources of protein. Normally, these belong to the "Meat" group in the Healthy Diet Pyramid. However, they have large amount of fat and oil after deep-frying.

Preserved Foods

Sausage, Chinese preserved pork sausage, preserved eggs

Most of the preserved foods used salt as flavoring and as preservatives to store food a longer time. Foods like sausage, Chinese pork sausage, and preserved eggs have high sodium content. Mostly, people would assume those preserved foods are belong to the "Meat, Fish, Eggs, Beans and dairy" groups. However, sausage contains large amount of energy (76% of energy) from fat and saturated fat, as well as large amounts of salt.

Dry salted vegetables

Due to their high salt content as mentioned above, these should be consumed less often and in smaller amounts than fresh vegetables.

Sugar-added Food

Cream cake

The main ingredient of a plain cake is flour, and flour belongs to the bottom layer of the Healthy Diet Pyramid - "Grain" group. However, during the making process, lots of cream, butter, sugar and oil are added, while calories are also added from "Fat, Sugar and Salt" group on the same time. Thus, cream cake is a high-energy food to be eaten less frequently.

By reading the food labels from the above foods, you can notice cream cake is high in fat and saturated fat as well as low in fiber while Marie biscuits are higher in fiber and lower in fat, and are a better choice. Next time when you shop for any food, try to read the food labels and understand the food contents; they can help you to make a wiser selection. For more about food labeling, click here

Sweetened Drinks - Soda, Boxed fruit juice

Though soft drinks contain water and can partially relieve thirst, their high sugar content gives you 'empty calories' with no other nutrients. So, these are basically flavored sugar water. Drink these only occasionally as they belong to the top layer of the Healthy Diet Pyramid. Choose plain water or other beverages instead most of the time. Low-fat milk is rich in calcium and non-sweetened fruit juice is rich in Vitamin C while soda has them neither.
