Diarrhea is a common condition that can be caused by various factors, including diet. Changing your diet to include primarily fruit can potentially lead to diarrhea due to the high fructose content in fruits. Fructose is a sugar that the body can only digest in limited quantities, and consuming excessive fructose can result in diarrhea. Additionally, a sudden shift in diet can disrupt your gut flora or microbiome, leading to temporary digestive issues, including diarrhea. It is worth noting that diarrhea can also be caused by other factors such as food intolerances, infections, or underlying health conditions. If diarrhea persists or is accompanied by severe symptoms, it is recommended to consult a healthcare professional for proper diagnosis and treatment.

What You'll Learn
Fructose intolerance
Fructose is a natural sugar found in fruits, some vegetables, and honey. Fructose intolerance is the inability to properly absorb fructose. There are two types of fructose intolerance: dietary and hereditary. Hereditary fructose intolerance is a genetic disorder caused by a mutation in the ALDOB gene, which results in a reduction of the enzyme aldolase B, impairing the body's ability to metabolize fructose. This can lead to a buildup of fructose-1-phosphate in liver cells, which is toxic and can cause liver cell death over time. Symptoms of hereditary fructose intolerance include nausea, bloating, abdominal pain, diarrhea, vomiting, and low blood sugar (hypoglycemia). Repeated ingestion of fructose-containing foods can lead to liver and kidney damage, and in severe cases, seizures, coma, and even death.
Dietary fructose intolerance, also known as fructose malabsorption, occurs when the cells in the intestines cannot properly absorb fructose. This can result in similar symptoms to hereditary fructose intolerance, including bloating, diarrhea, constipation, flatulence, and stomach pain. Fructose malabsorption is estimated to affect approximately 30-40% of people in the Western hemisphere, but the cause is unknown.
A sudden increase in fruit consumption can cause diarrhea due to the high fructose content. The body can only digest a certain amount of fructose at one time, and consuming more than this amount can lead to diarrhea. Additionally, the high fiber content of some fruits and vegetables can also contribute to diarrhea, especially for individuals with inflammatory bowel disease (IBD).
If you suspect that your diarrhea is caused by fructose intolerance, it is important to consult a doctor for proper testing and diagnosis. Keeping a food and symptom diary can also help identify any food triggers and eliminate them from your diet. Treatment for diarrhea caused by fructose intolerance may include over-the-counter medications, increasing fluid intake, and following a BRAT (bananas, rice, applesauce, toast) diet or a low-fiber diet.

High FODMAP content
FODMAP is an acronym that stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. FODMAPs are a group of carbohydrates that can cause digestive issues in some people, including diarrhoea. They tend to increase water content in the small intestine, increase gas production through fermentation, and can lead to excess production of short-chain fatty acids. This can result in abdominal pain, bloating, flatulence, and alterations in bowel habits.
Fructose, a component of table sugar that occurs naturally in fruits, is a FODMAP. The body can only digest a certain amount of fructose at one time, and consuming more than that can cause diarrhoea. Sorbitol, a sugar alcohol that occurs naturally in some fruits, is another FODMAP. Sugar alcohols are commonly used as sweeteners and can cause diarrhoea, especially when consumed in large amounts.
High FODMAP fruits include apples, watermelon, mangoes, cherries, figs, nashi pears, pears, and dried fruit. Legumes and pulses, including red kidney beans, split peas, falafels, and baked beans, are also high in FODMAPs, specifically GOS. The GOS content of legumes and pulses is affected by how they are prepared, with canned lentils containing half the GOS of boiled lentils. Dairy products are another source of FODMAPs, with soft cheeses, milk, and yoghurt being high in lactose. However, many dairy foods, such as butter and cheese, are naturally low in lactose.
A low-FODMAP diet is often recommended for people with digestive issues to help identify and eliminate trigger foods. The diet consists of three phases: elimination, reintroduction, and maintenance. During the elimination phase, all high-FODMAP foods are avoided, followed by the systematic reintroduction of FODMAP foods one at a time during the reintroduction phase. The maintenance phase involves creating a sustainable, personalised diet plan based on the findings from the previous phases. It is important to consult with a healthcare professional before starting a low-FODMAP diet to ensure it is suitable for your individual needs.

Gut flora adjustment
A diet high in fruit can cause diarrhea, particularly if your body struggles to absorb fructose, a natural component of fruit. Diarrhea can also be caused by a change in diet, as certain foods can worsen symptoms.
The gut microbiome refers to the microorganisms living in your intestines, including bacteria, viruses, and fungi. Gut flora, or gut microbiota, is essential for maintaining a healthy body. It contributes to our health by making vitamins, fighting infections, and even helping to activate drugs.
Diet is a significant modulator of the gut microbiota, and a healthy gut will have an easier time processing food and eliminating waste. A balanced gut flora will have a higher level of diversity in gut bacteria, which is associated with improved general mental and physical health.
To restore gut flora, you can try the following:
- Consume more fibre, as gut flora thrives on it.
- Eat polyphenols, which are compounds found in plant foods that have prebiotic, anti-inflammatory, anti-oxidative, anti-carcinogenic, and anti-microbial properties.
- Exercise, as it has a direct effect on gut bacteria.
- Take probiotics, which are beneficial bacteria that live in the gut and can help reduce IBS symptoms and prevent diarrhea.
- Reduce stress, as chronic high levels of stress can negatively impact your gut.

Food intolerance
One common food intolerance is lactose intolerance, which occurs when the body does not produce enough of the enzyme lactase to break down lactose, a sugar found in milk and dairy products. Other examples of food intolerances include histamine intolerance, where the body cannot break down histamines, naturally occurring chemicals found in foods like cheese, pineapple, bananas, avocados, chocolate, and wine; and gluten intolerance, where the body cannot tolerate gluten, a protein found in wheat, rye, and barley.
Now, regarding the question of whether changing one's diet to mainly fruit can cause diarrhoea, the answer is yes, it may. This is because fruits contain fructose, a natural sugar that the body can only digest in limited amounts. Consuming more fructose than the body can handle may lead to diarrhoea. Additionally, some fruits are high in fibre, and a sudden increase in fibre intake can cause digestive issues, including diarrhoea. However, it is important to note that everyone's digestive system is different, and some people may be more sensitive to dietary changes than others.

Fibre content
Fibre is a complex carbohydrate that can be categorised into two types: soluble and insoluble. Soluble fibre dissolves in water and is found in foods such as oat bran, beans, and most fruits. Insoluble fibre, on the other hand, does not dissolve in water and is present in wheat bran and certain vegetables. A balanced diet should include both types of fibre, as they have different roles in maintaining digestive health.
When it comes to diarrhoea, the link between diet and this condition is well-established. Fibre, in particular, can have varying effects depending on the type and amount consumed. A sudden increase in fibre intake, especially if one is unaccustomed to it, can lead to digestive issues such as constipation, gas, and diarrhoea. This is because the gut needs time to adjust to the new diet, and a sudden overload of fibre can overwhelm the digestive system.
Fibre, especially insoluble fibre, can worsen diarrhoea. This is because insoluble fibre absorbs water and adds bulk to stools, which can accelerate the passage of food through the intestines. During an episode of diarrhoea, it is recommended to opt for a low-fibre diet, at least initially, to give the digestive system a chance to recover.
However, soluble fibre can be beneficial in reducing diarrhoea. It dissolves in water and promotes the formation of firmer stools. This type of fibre is often recommended for individuals with irritable bowel syndrome (IBS) as it can help regulate bowel movements.
It is worth noting that the impact of fibre on diarrhoea is highly individualised. While some people may experience worsened symptoms with increased fibre intake, others may find relief by including more fibre in their diet. It is always advisable to consult a healthcare professional or a dietician before making significant dietary changes, especially if one is experiencing persistent diarrhoea or other concerning symptoms.
In summary, fibre content plays a crucial role in managing diarrhoea. While insoluble fibre is generally recommended to be limited during active diarrhoea, soluble fibre can be beneficial in promoting digestive health and reducing symptoms. Gradual adjustments to fibre intake and a well-rounded understanding of different fibre types can help individuals effectively manage their digestive health.
