Science Says: Soda is Killing Your Brain – Even Diet Soda

Have you given up your sugar-laden soda? If so, that is an excellent idea, but if you have replaced it with the sugar-free thing, you may be messing with your brain in a big way. Science says for people over 45, drinking diet soda increases the risk of stroke and dementia by three times and does a lot more damage than you think. However, there are some fantastic and entirely healthy alternatives that can help you put your soda habit to bed, once and for all.

Let’s start with the bad news and finish up with the good – it’s always great to end on a positive note.

In the 1950s and 60’s a dietary disaster based on false information ran through the country without brakes. Sugar-funded research studies that were entirely untrue shifted the general public’s perception to believe that fat, not sugar, was the bad guy – causing horrible health issues like obesity, diabetes, and heart disease. That one lie still impacts us today – even though we now know the horrible truth about sugar and the good news about fat. Healthy fats are necessary for our wellbeing, and sugar is, in fact, the bad guy.

However, even now that we know this, people are still drinking too much soda. Too much soda means too much sugar, which means significant impacts on the body – even the brain. But what about diet soda? It’s better right…wrong!

Increased risk of dementia and stroke 

Researchers from Boston University looked at the soda drinking habits of almost 3,000 adults, including some over 45 years of age. It was in this age bracket that the data got very dark. People over 45 years who regularly drink diet soda have a tripled increase of developing dementia or having a stroke. This risk even holds true after considering other risk factors such as smoking, diet, overeating, and level of exercise.

Accelerated brain aging found

With the help of MRI imaging, cognitive tests, and existing data, researchers found that people who drank two more sugary drinks per day or more than three sodas had smaller brain volume – actual brain shrinkage in the size of the hippocampus was found. This accelerated aging of the brain resulted in poor memory. Sadly, these are risk factors for Alzheimer’s. They also found that drinking diet soda resulted in a smaller brain volume.

Other things diet soda is doing to your body

Your brain is not the only thing hurt by drinking diet soda. Here are some other well-researched health impacts.

  • Kidney damage: People who drink diet soda over a long period have a 30 percent reduction in kidney function.
  • Kidney stones: Individuals who consume soda regularly may develop kidney stones because minerals are being flushed from their bodies.
  • Depression: People who drink more than four cans of diet soda per day have a 30 percent higher risk of developing depression.
  • Type 2 diabetes and metabolic syndrome: Drinking diet soda daily increases your risk of developing type 2 diabetes by 67 percent and your risk of metabolic syndrome by 36 percent.

Better and healthier options

As bad as that news is for soda drinkers and people drinking other sugary beverages daily, like fancy coffee, juice, etc…there is good news. I promised, right? The good news is that water is not the only beverage option – many healthy and delicious drinks will slash your risk of health issues and promote wellness. Here are some favorites.

Organic kombucha – Drinking kombucha gives you the fizz fix that you love with the added benefit of probiotics which feed your gut bacteria and improve health. If you get ambitious, try making your own kombucha known as  “Immortal Health Elixir” by the Chinese.

Tea-  Whether hot or iced – tea is a delicious and healthy soda alternative. Herbal and green teas are bursting with health-promoting properties. They boost metabolism, improve cognitive performance, help you sleep, reduce stress, and even feed your brain – resulting in an 87 percent reduced risk of developing Alzheimer’s.- Who wouldn’t trade the increased risk you get with soda for the decreased risk you get with tea?
