Sugary drinks are one of the lead contributors of onset diabetes, obesity and tooth decay. There is a high concentration of sugar, approximately 10 teaspoons, in a single can of coca-cola. As per the World Health Organization’s (WHO) standards, an average person should consume no more than 6 teaspoons of sugar in a day.

Even though, sugary drinks can taste amazing at times, they can have adverse effects on a human’s body, and hence, should not be consumed on regular basis. According to the Harvard School of Public Health, “people who drink 1-2 cans of sugary beverages daily are 26% more likely to develop type 2 diabetes”. Another report showed that almost 184,000 people die each year due to sugary drink consumption.

The consumption of Coca-Cola has been on the rise for more than a decade now. According to the Centers for Disease Control and Prevention, around half of the US population drink sugary beverages on any given day.

Here are some consequences of drinking Coca-Cola everyday:

Weight gain

One of the most visibly evident results of drinking sugary drinks is weight gain. According to Naik, the high sugar level in a can of Coke should immediately cause us to vomit, however, the phosphoric acid present in it tones the sugar down and lets the body retain it. The blood sugar levels increase drastically within the first 20 minutes of consumption, sending your liver in overdrive. Large amounts of insulin is produced which changes the glucose into fat.

The intake of these drinks also triggers the production of dopamine – a neurotransmitter that controls pleasure and reward centers of the brain. This is why Cola might get addictive –it induces the same feelings as heroin or cocaine, except on a slightly lower level.

Vitamin deficiency

The phosphoric acid in Coke paired with caffeine, prevents the nutrients from getting absorbed into your body. The vitamins and minerals are washed out of your body after about 60 minutes of having a drink. If it keeps happening everyday, you’ll eventually develop a vitamin deficiency.


The caffeine in Coca-Cola prevents the feeling of fatigue, however, the sleep deprivation might lead to anxiety. Since, sugary drinks can get addictive, if you reduce its intake, the ‘withdrawal’ symptoms might include anxiety, headache and irritability.

Tooth decay

Another side effect of having coke everyday is tooth erosion. The acidic nature of the drinks can cause tooth enamel to decay, leading to cavities. Low levels of Calcium due to the vitamin deficiency can cause your teeth to decay from inside out, ultimately destroying them.

Renal failure

It might come as a surprise, but yes, sugary drinks can cause kidney failure! Even diet coke can affect the healthy functioning of your organs. Artificial sweetners present in the drinks can have adverse effects on your kidneys, eventually causing them to fail.

Cardiac problems

Within 40 minutes of Coke intake, all the caffeine has been absorbed into your body. This causes your pupils to dilate and increases your blood pressure.  A research, done over the period of 28 years in USA, showed that there was a 31% increased risk of death from cardiovascular diseases for people who consumed 2 or more sugary drinks per day.

Increased risk of cancer

Carcinogens are produced during the manufacture of caramel coloring used in soft drinks which can lead to an increased risk of cancer. Researchers have found that consuming one can per day could be enough to expose you to potentially cancer-causing levels of a chemical called 4-MEI (4-methylimidazole).

Rapid Aging

The high level of sugar in the drinks has an inflammatory effect on your body. It dehydrates the skin and leads to appearance of lines and wrinkles, making your skin saggy and dull. It is also known to promote eczema, dry and itchy skin and acne.
