Fried Foods and Its Danger

All of us love tasty foods, they are giving you energy, motivation to finish the day and to get past those stressing afternoons, as well as entertain and comfort us. Our body needs nutrition to function properly so it is not surprising that our brain makes us love delicious foods as it is probably part of our surviving instinct. The problem in modern days, is that food is no longer the same as how our ancestors used to eat and many of them become less nutritious but fattening.

One of the stars of foods that often becomes the culprit of various health problems including rapid weight gain is fried foods. We are sure most of us love fried foods, in fact probably the majority of people are eating them at least once a day for the main meal or snacks. They are amazing, not only tasty from the herbs and seasonings used but also the different crunchy texture that can’t be copied by another cooking method precisely which is why it is very difficult to let them go.

The connection of fried foods and rapid weight gain is familiar in our ears and one of the basis is a study published by the BMJ which found that women who ate more than one serving of fried chicken daily were 13% more likely to die prematurely from any cause and 12% more likely to have a heart-related problem compared to those who don’t eat any fried foods. This also includes those eating fried fish or shellfish on a daily basis because they are 7% more likely to die early as well.

This study is based on a questionnaire which is not the best in terms of accuracy but the researchers have controlled many of the variables that may alter the result such as lifestyle, overall diet, education, and income level. Another study related to fried food and health problems is done by Harvard School of Public Health which found that those with certain genetic makeup will gain more weight by consuming fried food compared to those without the genetic issue.

Even if your genetic makeup is not prone to gain more weight, fried foods are still an unhealthy option that should not be consumed on a daily basis, moreover in every meal throughout the day. Most of us are buying them from fast food chains or restaurants since deep frying at home is often messy and not only fried foods use batter which add calories and absorb oils, the oil itself has been used for many times, making them dangerous for your cholesterol level.

About Convection Oven or Air Fryer

The majority of people know the bad side of fried foods but not all of us are capable of not eating or extremely limiting the consumption of fried foods which clearly causes some health effects if consumed too often especially those we bought from fast food chains or restaurants. We then look for alternative cooking methods that can give the same experience as fried food but without the huge amount of oils and added calories of heavy batter right conveniently in your kitchen.

If you have been baking ingredients as an alternative to fried foods and reduce vegetable oil consumption but can’t find the similar texture of those crunch and crispness of deep fried foods, Convection Oven or Air Fryer can be a better solution. Some of us must already have either of them in the house for different cooking purposes but these two are very amazing when it comes to creating crispy and dry texture without having to use too much oil.

These cooking appliances are very useful because you can cook almost anything with them yet, they are also slightly different. Convection oven itself is not a new thing and we probably already have them around to cook dishes which require a more even heat to cook properly as it circulates the hot air inside in comparison to a regular oven with a fixed heat that requires you to flip them or rearrange them to get the best result.

Air fryers on the other hand are fairly new compared to ovens in general because they were first introduced in the consumer market by Philips just a decade ago. They were a niche product back then and not many of us understand how they can become very useful in the kitchen as we are pretty skeptical about how this small, jar-looking appliance can do. Turns out we were wrong, this compact appliance is a great tool and very much convenient especially if you like fried food and want a healthier option.

Convection Oven or Air Fryer Design

You can find Convection Oven and Air Fryer from so many different brands out there but in general they will work the same way and quality wise, it will vary among the model as well as price range too. From how they consume space on your kitchen top, Air Fryers will be more efficient because they are very small depending on the capacity you prefer to have and in general they are about the same size as your espresso machine. 

In comparison, the countertop Convection oven is slightly larger and more about the same size as your microwave so you will have to allocate more space as well. If oven have this rectangle shape, the air fryer is often comes in a square or oval shape with a wide bottom and flat top. They do carry digital display to deliver some related information and if you open the compartment of air fryer like pulling a drawer, the convection oven opens like a cabinet.

Convection Oven or Air Fryer Mechanism

You must wonder how Convection Oven and Air Fryer are separated because they are using the same mechanism. Both of them are cooking the food by circulating the hot air generated from the heating elements using a fan through the room and circulating it around the food itself to deliver a more even roasting effect. Until this point they are the same but, what makes them different is the fact that the air fryer is doing it more rapidly and this becomes more intense as well since the room is significantly narrower.

This is why while convection ovens can cook food faster compared to regular ovens, they are still not as fast as air fryers when you need to hurry up cooking those fish fillets or chicken katsu. The basket design is also optimizing the air circulation to make sure all surfaces are heated properly yet, it is not perfect as well since you will need to flip them over as the top area will get the best exposure to heat. 

Convection Oven or Air Fryer Performance

Moving into performance, a full-size Convection oven is versatile however, and if your range comes with one already, we don’t think an air fryer can replace it as you can bake various and lots more foods together inside a full-size oven. Air fryers however, is fast and convenient which makes it a great addition in modern apartment kitchens. When it comes to which is tastier you may find it very subjective but personally oven is better when you are cooking heavier or thicker raw foods like chicken wings and beef patties.

For air fryers, we tend to use it on breaded items such as chicken katsu or frozen french fries as the result is quick and pretty crunchy as well despite not as crisp as what you get when deep frying them. If you like cheese sticks, nuggets, or jalapeno poppers, this appliance will offer better experience.

Convection Oven or Air Fryer Features

The last part we want to mention is their features but in general Convection Oven and Air Fryer controls are the same just like regular ovens. Usually an air fryer will need to be warmed up first before using but some models like this Philips Avance collection can be used instantly. On the other hand you will find the same controls which usually function as timer and temperature adjustment to make sure we are cooking at the right temperature and amount of time.

Convection Oven vs Air Fryer

These kitchen appliances are amazing for your kitchen because we can eat fried foods without the high amount of oils and higher calories. The difference between them is that the Air Fryer will be smaller in comparison to Convection Oven and it also circulates the hot air faster due to the limited space. While Convection oven is ideal for more food and thicker or heavier ingredients, Air Fryer will be better for frozen foods like cheese sticks and nuggets or French fries while being faster as well as cooking.

Convection Oven Air Fryer
- Larger- Compact

- Slower hot air circulation

- Faster air circulation
- Ideal for larger ingredients
- Ideal for frozen foods
- Better for cake or cookies- Cook faster


You can pick any option as it is highly depending on your personal preference. In our opinion however, if what you are cooking is more like baking such as chicken or meat patty, a convection oven will be better but if you will cook in a little amount and mostly frozen foods, Air Fryer is more convenient.
