6 Illnesses Caused by Poor Nutrition

6 Illnesses Caused by Poor Nutrition

A healthy diet doesn’t just give you a flatter stomach; it’s also a preventative measure for specific health conditions. Let's have a look at some of the most common illnesses caused by poor nutrition.  


Hypertension is also known as high blood pressure and its impact on your day to day life can be dramatic. While there are many causes of hypertension, consuming an inadequate diet can lead to the condition. Unfortunately, many sufferers don’t have any symptoms, until the disease affects their heart. Luckily, changing your diet can reduce the risks of high blood pressure. 

People that consume lots of sodium, bad saturated fats and struggle to regulate their calories are most at risk of hypertension. 

Replace bad foods with healthier options including lots of green leafy vegetables and learn which fats are the best to consume. 


As you get older, it’s only natural that you find it challenging to maintain your weight. But when you let your weight get out of control, it can leave you with irreversible conditions. One such condition is osteoarthritis. 

Osteoarthritis is a painful disorder that causes joint damage. It mostly affects the hips and knees, which makes walking and lifting difficult for sufferers. While some dispute that a poor diet leads to the condition, many others believe obesity puts extra pressure on the bones, which can lead to it developing. 

Heart Disease

Did you know that a quarter of deaths in the UK each year are attributed to heart disease? Diet is one - if not - the most crucial factor in reducing the risks of heart conditions. In most cases of heart disease, a narrowing of the arteries causes the condition because it reduces the blood supply. To reduce the risks of heart conditions, you need to consume a healthy low inflammatory diet. 


Tooth Decay 

With bad diets causing conditions such as heart disease and osteoarthritis, people often forget about tooth decay. But it’s one of the most common illnesses caused by poor nutrition. Tooth decay can also lead to a lot of expensive dental treatment. 

Sugary drinks and foods cause tooth decay. When you consume sugar, the bacteria in your mouth produce acid to break it down. People that regularly eat sugary treats create so much acid; it starts to dissolve the tooth surface. 

Did you know that one can of regular Coke contains 35g of sugar? That’s nine teaspoons in one drink. Health guidelines state that the average adult should consume no more than 30g of free sugars a day, so one can will take you over your daily limit. 

The other culprits are chocolate, sweets, cakes, and biscuits. While fruits have natural sugars, they can still contribute to tooth decay. The key to combating the condition is regulating your sugar intake. 

Type 2 Diabetes 

Type 2 Diabetes is a serious condition that impacts your daily life. The main risk factor of developing diabetes is being overweight. Of course, there’s a direct correlation between obesity and consuming a bad diet. 

The improper use of insulin causes diabetes. If your body contains too much fat, insulin cannot perform its primary function, which is to move sugar out of the blood and into your cells. The pancreas then automatically produces more insulin, which destabilises your blood sugar. 

Junk foods often contain refined sugars and go through processing. They taste addictive, but cutting this food type could save you from diabetes. 

Digestive Issues 

Digestive issues come in many forms, but all of the symptoms cause discomfort, pain and can even interrupt your daily life. Common symptoms include stomach pain, bloating, constipation and diarrhoea. 

If you consume more unhealthy foods than nutrient-dense foods, your digestive system will struggle to function correctly. Two of the most common conditions a poor diet causes are gall bladder issues and diverticular disease. 

Diverticular Disease

When your colon struggles to move waste through your system, it uses excessive force which causes small pockets that are called diverticular. If you don’t consume enough fibre, you increase your risks of getting diverticular. 

The condition is painful, and the pockets can become infected. In some cases, hospital admission is required. 


Gallstones form in the gallbladder, and they are made from bile. The condition is caused by consuming high amounts of fatty foods and cholesterol. If you develop gallstones, you’ll need surgery to remove them. 

The biggest issue with gallstones is the pain they cause. Symptoms include nausea, vomiting, abdominal and back pain, and yellowing of your skin. A healthy diet with lots of fibre dramatically reduces the risk of gallstones. 

Eat Good, Live Well 

The illnesses caused by poor nutrition that we’ve mentioned are all avoidable if you eat healthily. Your body needs vitamins and minerals to function correctly. If you regularly feel bloated, sluggish and lack motivation, you’re not getting the nutrients you need. 

One of the most significant issues people have is finding the time to prepare and cook healthy meals. It’s so easy to grab a ready meal, but it’s also the fastest way to put yourself at risk of a severe health condition.
