Processed Foods and Health

As the name suggests, processed food is food which has undergone some form of processing to turn raw ingredients into a food product.

A large amount of our food these days is processed, from the milk in your breakfast to cakes and microwave meals.

Processing includes the preparation of food, killing bacteria (e.g. pasteurisation), the addition of additives and hydrogenation of ingredients.

Are processed foods bad for our health?

There is a lot of debate about just how bad processed foods are for us. The general consensus is that the less processed food is the better.

Many foods fall into the category of processed foods and some have fallen under scrutiny more than others.

The processing in of vegetable oils is one that has been a hot topic recently, with claims that refined oils may be responsible for inflammatory conditions such as type 2 diabetes.

What are the benefits of processed food?

• Preserving food by preventing bacterial growth and allowing food to be stored for longer
• Improving the taste of food
• Improving the appearance

It should go without saying that the primary benefit of processed foods is to the food manufacturers and distributors, in that it has allowed them greater maximise profits by increasing satisfaction and shelf life.

What are the disadvantages?

• Loss of vitamins – e.g. canned vegetables
• Reduced amount of fibre – particularly in white breads, white pastas and white rice
• Highly processed foods tend to be digested more quickly which can be particularly disadvantageous for people with type 2 diabetes

Which processed foods to avoid?

As a general rule, make a habit of avoiding foods with a relatively high number of difficult to recognise ingredients. Contrary to their supposed aim, certain foods with reduced fat or salt content may be bolstered with additives that may be worse for us to consume.

Typical foods that are identified as ones to generally avoid include:

• Cheap supermarket meats
• Hotdogs
• Ready meals
• Fast food
• White bread, white pasta, white rice
• Cakes, biscuits, buns, pastries
• Margarines

The list is not exhaustive bit covers some of the main culprits, including some of those we’ve been lead to believe are healthy for us (margarines for example).

Processed foods and links with poor long term health

Processed meats have been consistently linked with a number of cancers.

The amount of salt used, the poor quality of the meat as well as the number of additives that are used in the meat are all possible reasons for the link between processed meat and poor health.

Trans fats

Trans fats have been banned in a number of countries but are currently still tolerated by the UK.

Refined oils

Refined oils are treated with heat, and often chemicals, and are thought by some to be harmful for the body.

Vegetable fats

Vegetables fats can be assumed to be the by-product of this process. Vegetables oils within ingredients can also be assumed to be refined oils.

Emulsifiers and hydrogenated ingredients are used to keep foods together and improve the texture.

They haven’t generally received as much bad press as the above ingredients but the health conscious may wish to limit exposure to these.

Preservatives and antioxidants generally need to be tested for toxicology before they can be regarded as safe for use in food.

These tests are typically short term and are never performed on humans.

Whether the levels permitted in food really are safe over a long term period is one of the many food health debates that persist today.
