Some preliminary research suggests that a high-sugar diet raises blood sugar levels, increasing free radicals and compounds that promote inflammation.

Over time, excess sugar increases the risk of obesity, increases the risk of diabetes and can also increase the risk of developing conditions like certain cancers and chronic diseases like heart disease.

When we talk about how much sugar a day is too much, the answer is not entirely clear.

The latest dietary guidelines recommend that added sugars make up no more than 10 percent of your daily calories.

This is about 38 grams or 10 teaspoons for women whose diet contains 1500 calories or 50 grams (13 teaspoons) for men's diet contains 2000 calories.

The American Heart Association and the World Health Organization believe that these amounts should be less: 25 grams (6 teaspoons) per day for women and 36 grams (9 teaspoons) per day for men.

The following KP brings some signs that you are consuming a lot of sugar:

Digestive problems

Some studies suggest that sugar can reduce the variety of healthy bacteria in the gut in just one week, while slowing down the digestive system.

Fiber-rich foods have a positive effect - and people who eat a lot of sugar generally do not eat a lot of fiber.

Acne

While experts say acne has nothing to do with diet for the vast majority of people, some studies link acne outbreaks to excessive consumption of sugary foods.

In theory, sugar increases the production of hormones associated with inflammatory hormonal acne, which usually appear around the jaw and mouth.

Mood swings

Some research has linked sugar to mood swings, such as depression.

In fact, sugar can affect neurotransmitters in your brain that regulate your mood.

Sugar causes the increase of the "good feeling" hormone serotonin.

After a while, there comes a drop in mood, so you may feel upset, nervous and tired.

Sleep problems

If you eat a cake or some candy just before going to bed, it can cause sleep problems, KP reports.

Caries

Sugar feeds bacteria in the oral cavity, producing acids that are consumed in tooth enamel, which leads to caries.

Bounce

Sugar-rich foods can cause bloating.

It is also important to note that if you are sensitive to sugars like fructose (fruit sugar) and lactose (in dairy products), other symptoms may appear that are common to people who have problems with improper bowel movements.

High blood pressure

Sugar is worse for blood pressure than salt, according to a study published in the journal

Open Heart

.

A diet high in sucrose in just a few weeks can raise blood pressure.

Another study from

the British Journal of Nutrition

found that for every sugar-sweetened beverage, the risk of developing hypertension increased by eight percent.
