In our modern and fast-paced lives, it can be difficult to keep a healthy balance of nutrients in our food. Sugar is one of these nutrients, and the cells in our body would die without it.

Consuming too much sugar, however, raises the risk of several problems, including poor dental health, obesity, and type 2 diabetes.

To keep control of sugar levels, it helps to know just how much sugar there is in the food we eat. Here, we list the sugar content of numerous everyday foods, both processed and natural.

What is sugar?

Sugar is a simple carbohydrate that belongs to a class of chemically-related sweet-flavored substances. It comes in many different forms. The three main types of sugar are sucrose, lactose, and fructose.

Even though our cells need sugar (glucose) to survive, consuming too much of it can cause numerous health problems. Added sugar contains no beneficial nutrients and, in excess, only contributes to tooth decay, diabetes, and obesity.

The American Heart Association (AHA) say that added sugars "contribute zero nutrients" and are just empty calories "that can lead to extra pounds, or even obesity, thereby reducing heart health."

Being aware of the existing and added sugar contents of the foods and drinks we consume is vital to our health - even more so today because so many products have sugar added to them.

In March 2015, the World Health Organization (WHO) published new guidelines recommending that adults and children alike reduce their consumption of free sugars to less than 10 percent of their total energy intake, with a further reduction to below 5 percent associated with additional health benefits.

The term "free sugars" refers to glucose, fructose, and sucrose added to foods and drinks, as well as sugars naturally present in syrups, honey, and fruit juice. The term does not apply to sugars found naturally in fresh fruit, vegetables or milk because there is no evidence associating the consumption of these sugars with adverse effects.

A single teaspoon of sugar is around 4 grams. The WHO recommend that we should reduce daily sugar consumption to 5 percent of daily energy intake; that would equate to 6 teaspoons of sugar.

Sugar content in common foods and drinks

Below we have listed some common everyday foods and drinks, together with their sugar content. This is designed to give a little guidance when making dietary choices. Some of the following items' sugar content may come as a surprise:

In June 2012, researchers from Yale Rudd Center for Food Policy & Obesity revealed that even though cereals aimed at kids had become more nutritious, cereal companies (such as Kellogg, General Mills, and Post) had increased their advertising spending considerably. Cereal advertising aimed at children increased by 34 percent between 2008 and 2011.

Marlene Schwartz, deputy director of the Rudd Center, said:

"While cereal companies have made small improvements to the nutrition of their child-targeted cereals, these cereals are still far worse than the products they market to adults. They have 56 percent more sugar, half as much fiber, and 50 percent more sodium.

The companies know how to make a range of good-tasting cereals that aren't loaded with sugar and salt. Why can't they help parents out and market these directly to children instead?"

How much sugar does fruit contain?

Why should I monitor my sugar intake?

The American Heart Association has urged people to cut their added sugar intake because of evidence that it can cause the following health conditions:

• Obesity - scientists at the Medical Research Council found that eating more sugar is associated with obesity.
• Heart disease - research published in JAMA Internal Medicine investigated sugar intake and cardiovascular disease related deaths. They concluded that: "Most U.S. adults consume more added sugar than is recommended for a healthy diet. We observed a significant relationship between added sugar consumption and increased risk for CVD [cardiovascular disease] mortality."
• Type 2 diabetes - although sugar does not directly cause diabetes, individuals who consume more sugar than average are more likely to be overweight, which is a risk factor for type 2 diabetes.

Added sugar consumption far too high

The U.S. Centers for Disease Control and Prevention (CDC) report that far too many Americans are consuming too many calories from added sugars. A report published in 2013 revealed that nearly 13 percent of adults' total caloric intake is coming from sources such as sugar and high fructose corn syrup.
