A strong digestive system ensures that you won't suffer all sorts of digestive disorders such as irritable bowel syndrome (IBS), bloating, constipation and diarrhoea. It will also prevent other health issues such as weight gain, eczema, chronic exhaustion and asthma.

Good digestion starts in the mouth. Some foods may seem healthy, and they are, but if you already have a weak stomach or are just recovering from an illness, it's best to not each so much of these 4 foods as they can be harmful to your digestion. 

1. Chocolate

While it’s not the healthiest of choices, a little bit of chocolate (especially dark chocolate) can serve as an energy boost after a strenuous workout.

But if you suffer from constipation or irritable bowel syndrome, chocolate can actually worsen the symptoms. Those with lactose intolerance may also react badly to the dairy in milk chocolate as it stimulate cramps, bloating, and diarrhoea.

2. Diary Products

Speaking of dairy, while getting the right amount of calcium is crucial in a balanced diet, many people can develop lactose intolerance from the diary found in milk and cheese. It can cause a lot of discomfort such as bloating, gas, and cramps.

The problem occurs when a person doesn’t make enough of the lactase enzyme which helps break down the lactose in dairy products. If you find yourself experiencing an upset tummy often after ingesting high lactose foods such as soft cheeses and milk, it's time to stop.

3. Berries

While berries can be full of vitamins and antioxidants, the types of berries that have tiny seeds in them such as strawberries, kiwi and figs can pose a risk to the digestive system especially those that have suffered from intestinal inflammation, infection or appendicitis before.

Eating these berries could cause them to get lodged in the intestinal pockets and create much discomfort while eating, so perhaps it's best to avoid eating too much of them. Or if you do want to eat them, to make sure you have a glass of water handy to wash the seeds down.

4. Corn

While corn is full of fibre and may seem like a good food for our digestion, it actually contains cellulose, which is a type of fibre that we are unable to digest due to us missing a certain enzyme in our bodies.

The fibre is corn actually ends up going in and coming out of our bodies in pretty much the same state. Our body has a hard time digesting it, and if your stomach is actually feeling weak either due to recovering from an illness or being lactose intolerance, it will be good to avoid corn in your diet.
