A Nutritionist’s Essential Guide to Processed Foods

From the bread we toast in the morning to the prepared meals we heat up for dinner, processed foods are an important part of our daily diet.

But not all processed foods are the same, and understanding the differences can help you make healthier choices.

What are Processed Foods?

Processing food simply means changing the food from its original form. This can be done through methods such as pasteurization, canning, drying, or freezing to extend its shelf life.

The two common types of food processing are: NOVA Classification System:

1. Minimal processingThis includes basic methods such as pasteurization to kill bacteria and canning to preserve fruits and vegetables.
2. Ultra Processing: This involves more complex processes that change the texture and structure of foods, often adding preservatives, emulsifiers and other additives.

It’s the latter type — ultra-processed — that’s of concern among health experts.

Ultra-processed foods is a broad category that includes packaged snack chips, chocolate candies, breakfast cereals, and more.

Scientific Research These foods are increasingly being linked to health problems such as obesity and type 2 diabetes.

for example, Randomized controlled trial They found that people whose diets provided 80% of their calories from ultra-processed foods consumed about 500 more calories per day than those whose diets consisted of 90% whole foods.

Are ultra-processed foods all bad?

It’s important to dig deep into the details.

1. Observational studiesAccording to these studies, the UPF of high-fiber breads and cereals is Type 2 diabetesFoods such as cakes, cookies and soft drinks may increase the risk of type 2 diabetes and heart disease. Also, some additives: Increases the risk of certain diseasesBut this evidence Inconsistent.
2. Randomized controlled trial: nevertheless High quality testing Although the ultra-processed diet was shown to provide a higher calorie intake than the unprocessed diet, the ultra-processed diet was almost twice as energy dense and lacked fruits and vegetables. This is important because an energy-dense diet: Voluntary excess calorie intake.

Thus, the best evidence to date seems to suggest that there are two main reasons why a high UPF diet may have adverse health effects.

1. Low in plant foods: Ultra-processed diets typically lack plant foods like fruits, vegetables, legumes, nuts and seeds.
2. High energy densityThese foods are high in calories per gram, making it easier to overeat and gain weight.

Tips for enjoying processed foods

In general, many UPFs, including potato chips, pastries, and other snacks, do not promote health and should only be enjoyed as a treat.

However, if you eat other types of UPF, such as pre-made meals or supermarket sandwiches (which tend to be low in veggies), you can increase the nutritional value of your meals by making sure you also eat plenty of plant-based foods.

This is useful in two ways:

1. Adding lots of vegetables to your diet will lower the energy density and help you feel full without overeating.
2. The dietary fiber contained in these foods provides nutrients for the bacteria in your intestinal flora, This suggests that the microbiome may help reduce calorie absorption.!

Here are some practical tips for putting science into practice.

• Add fruits, nuts and seeds to your cerealYou can also use frozen berries, or grate an apple and add it to your overnight oats.
• Add vegetables to ready-made meals: This can be easily done by using microwaveable vegetables.
• Eat fruit with your protein shake: The added fiber helps to make you feel full.
• Put avocado, cucumber, and tomato on the bread.: Make your sandwiches healthier by adding these tasty ingredients.
• Get creative with your burger toppingsAdd eggplant, mushrooms and slices of pineapple for extra flavor.

Processing such as adding sugar or salt should be avoided, but other processing methods, such as canning beans and freezing vegetables, can also create nutritious and convenient foods.

What are examples of processed foods?

Processed foods are usually altered from their original state for convenience, shelf life, or taste. Common examples include:

• canningFoods such as soups, beans, and canned fish are often processed to extend their shelf life.
• frozen food: Ready-made dinners and cooked meats are usually processed to make meal preparation faster and easier.
• Packaged Snacks: Foods like chips, biscuits and granola bars are often highly processed to enhance flavor and extend shelf life.
• Beverages: Soft drinks, flavored milks, and some fruit juices are often processed and contain added sugar and other additives.
• Bread and baked goods: Many store-bought breads, cakes and pastries are made with refined flours and preservatives to help them stay fresh longer.

Conclusion

Food processing can have complex effects on the nutritional value of foods. A diet that gets the majority of its calories from ultra-processed foods is not recommended.
