A diet based only on fruit can provide fiber, vitamins, and relatively few calories, but at the same time it can lead to deficiencies in protein, minerals, and other essential nutrients for the body.
A fruit-based diet is not a new way of eating. Our early ancestors used to eat this way, but times have changed. Can the human body really function without fats, proteins, and vitamins such as B12?
The fruit diet consists mainly of raw fruits. A person who follows it is called a fruitarian. It is a subtype of vegan eating, where small amounts of vegetables, seeds, and nuts are also allowed, but grains and most other foods are avoided. Most fruitarians get around 70 to 80 percent of their daily calories from fruit.
Like any very restrictive diet, this one also has both benefits and risks.
Main risks
Fruitarianism is a very restrictive diet that excludes many food groups. This means the body may lack important nutrients such as iron, calcium, vitamin D, zinc, omega-3 fatty acids, and B vitamins. Deficiencies in these nutrients can lead to fatigue, low mood, weaker immunity, weaker bones, dry skin, and brittle hair.
Another issue is natural sugar. Fruits contain fructose, and some types have a higher glycemic index, such as bananas, grapes, and tropical fruits. Therefore, a fruit-only diet is not the best choice for people with unstable blood sugar levels.
Protein deficiency can also occur. Although seeds and nuts are allowed, they are often not enough to meet the body’s needs.
Fruits also contain natural acids. If oral hygiene is poor, frequent consumption can damage tooth enamel and over time increase the risk of cavities.
