What is sugar and what would happen if I stopped eating it? A scientist explains

The world has declared a time-out on sugar consumption. The dangerous hyperlink between illness and dietary sugar was just lately outlined in a comprehensive assessment of revealed research.

Recognizing this hyperlink between extensively consumed meals and illness is crucial in marshaling forces to change harmful outcomes. These embody coronary heart disease, weight problems, sort 2 diabetes, tooth decay and a few cancers. For over a decade, my research has targeted on the mechanisms by which fructose consumption performs into illness.

A rising variety of African nations have joined the worldwide efforts to cut back sugar consumption. As an illustration, in an try to deal with weight problems, diabetes and different non-communicable illnesses, South Africa launched a tax on sugar-sweetened drinks in 2018.

It is arduous to keep away from sugar when it is turn out to be a standard a part of diets and once we rejoice particular instances with candy treats. However being extra conscious of what sugar is and the way it can have an effect on our well being is step one.

What’s sugar?

Sugar is a category of naturally occurring sweet-tasting molecules present in fruits, greens, vegetation and the milk of mammals. It may be extracted from these pure sources and concentrated in processed meals.

The sweet-tasting molecules in sucrose (desk sugar) are glucose and fructose.

Sucrose is a disaccharide. It is a molecule made from two easy sugars—glucose and fructose—in a 1:1 ratio and chemically certain. Sucrose is utilized in many processed meals.

Excessive fructose corn syrup, additionally utilized in processed meals, is a mix of the monosaccharides glucose and fructose. Normally the mixture is 45% glucose and 55% fructose.

Sucrose and high fructose corn syrup are extra concentrated in processed meals than in fruit and veggies.

Each are thought of added sugars when they’re added to foods and drinks. Moreover the candy style, they might be added for shade and texture, as a preservative or to assist fermentation.

There are different pure sugars discovered within the meals we eat. Lactose, or milk sugar, is a disaccharide made from two easy sugars—glucose and galactose—in a 1:1 ratio. It is present in mammals’ milk and produced naturally to offer diet to offspring, and in different dairy merchandise, resembling cheese and ice cream.

Honey, made out of nectar by honeybees, is primarily a mix of glucose and fructose monosaccharides with some maltose, sucrose and different carbohydrates. Maltose, which is present in breakfast cereals and breads, is a disaccharide of two glucose molecules.

Naturally occurring sugars are made by vegetation, bees or mammals based mostly on their wants.

The human physique wants glucose as a gas for each cell, particularly mind cells. That is one of many explanation why we want a steady blood glucose degree all through the day and evening.

The best way our our bodies use fructose is completely different. It may be became glucose, used as gas, or processed into fat, referred to as triglycerides. Extreme fructose in our diets can result in increases in blood triglycerides, liver fats, blood glucose, body mass index and insulin resistance (the place the physique can not simply take away glucose from the bloodstream).

Will increase in these markers can result in an elevated threat for metabolic dysfunction, sort 2 diabetes and non-alcoholic fatty liver disease (or metabolic dysfunction-associated steatotic liver illness).

Due to the distinction in how the physique makes use of glucose and fructose, and proof {that a} larger consumption of sugar results in worse well being outcomes, we have to be aware of the added sugar we eat.

What would occur if we give up consuming sugar?

A gaggle of scientists carried out a examine and revealed a set of analysis papers that detailed exactly what happened when over 40 youngsters (aged eight to 18) stopped consuming sugar and fructose for 10 days. The individuals did not cease consuming bread, hotdogs or snacks. They stopped consuming fructose. These research discovered significant reductions in:

• newly made triglycerides (or fat)
• fasting blood glucose
• blood strain
• fats saved on organs, together with the liver
• AST, which is a marker of liver perform
• insulin resistance, as their cells had been higher in a position to take away glucose from the bloodstream
• physique mass index.

The individuals additionally reported feeling higher and had been higher behaved.

The World Well being Group has made recommendations for adults and youngsters to cut back their sugar consumption to about 58 grams, or 14 teaspoons, per day or between 5% and 10% of complete caloric consumption.

This isn’t plenty of sugar.

Think about {that a} 300ml bottle of Coca-Cola or 240ml cup of sugarcane juice comprise about 30 grams of sugar. One piece of mandazi, a well-liked deep-fried Kenyan wheat snack, has about 4 grams of sugar, or about 6% of the WHO’s really helpful consumption contained in every small piece.

What can I do to decrease my sugar consumption to really helpful ranges?

First, maintain monitor of the whole lot you eat throughout a typical day, what you eat, while you eat and the way a lot you eat. Secondly, give your self a star for the contemporary greens and complete fruits you eat, and establish the meals which have added sugars.

Now, set an attainable purpose that particulars one factor you’ll be able to change to both:

1. enhance the entire fruits or greens you eat or
2. lower the quantity of added sugar that you simply eat every day.

This fashion, you might be aware of the added sugar you eat and regulate what you eat accordingly.
