With so many popular diet plans available, it can be challenging to assess which one is right for you. Often, diet plans are focused on weight loss more than overall health --- including plans that restrict carbohydrate and nutrient-rich foods such as vegetables but recommend high levels of saturated fat. Given the apparent unhealthiness of some diets, you may seek an all-fruit diet as an alternative. Although this may be beneficial, there are also potential drawbacks of an all-fruit diet. You should also consult a doctor before altering your diet.
High Vitamin and Mineral Intake
Fruits are considered to be healthy because they contain a wide variety of vitamins and minerals. According to Fat Free Kitchen, all fruits have significant levels of vitamins and minerals, which promote optimal health. Because of the low calorie count of most fruits, you will be able to obtain many vitamins and minerals without consuming a high amount of calories.
Very Low Fat Intake
Fat Free Kitchen says all fruits, except for avocado, have no fat. This means that unless most of the fruit you consume is avocado, your fat intake will be very low, which can be dangerous. Although fat is often considered unhealthy, the National Library of Medicine and National Institutes of Health explain that dietary fat is vital for overall health --- fat helps your body absorb vitamins, assists in the regulation of cholesterol levels, and fat is necessary for proper growth and development. With an all fruit diet, you will not be able to take advantage of the benefits of fat intake.
Risk of Tooth Decay
One of the biggest instigators for tooth decay is sugar, which is present in every fruit --- and sugar combines with saliva and oral bacteria to produce tooth decay, according to Elmhurst College. The college suggests a low sugar diet may be an effective preventative measure against tooth decay. The newspaper Daily Mail notes that citrus fruits such as oranges contain high levels of acid that promotes tooth decay. In addition, the Daily Mail explains that fruit juices may also promote tooth decay due to their high sugar content.
Very Low Protein Intake
In addition to being low in fat, fruits are also very low in protein. Like dietary fat, protein is an essential nutrient and is required for many bodily processes. Diet.com says that "protein should never be completely eliminated from the diet" and that low protein intake has a number of adverse effects. Risks of a low protein diet include inadequate intake of amino acids and iron. In addition, Diet.com points out that low protein intake may result in impaired immunity, low energy levels and muscle loss due to inadequate amino acid levels.
