Citrus fruits are a diverse group of fruits belonging to the Rutaceae family, known for their tangy flavor and high vitamin C content. Common citrus fruits include oranges, lemons, limes, grapefruits, and tangerines, but they also include clementines, mandarins, pomelos, kumquats, ugli fruit, citron, finger limes, yuzu, and many other sub varieties of citrus fruits. They are typically round or oval with a leathery rind and juicy flesh segmented into sections. 

The sweeter varieties of citrus fruits are discouraged on The Kaufmann Diet, particularly on The Kaufmann One Diet; while they are rich in nutrition, they are also higher in sugar, which can make starving potential pathogenic fungal infections more difficult. So while oranges and tangerines should likely be avoided (particularly in the beginning of the diet), the less-sweet varieties of citrus are encouraged. Most people are familiar with lemons, limes, and grapefruit, but some lesser known types of low-sugar citrus fruits include: 

  • Kumquats are unique among citrus fruits as you can eat them whole, including the peel. They have a sweet-tart flavor, but their small size means they typically contain less sugar than larger citrus fruits.
  • Pomelos are the largest citrus fruits and are similar to grapefruits but milder and sweeter. While they contain sugar, their large size means you consume less sugar per serving compared to smaller citrus fruits.
  • Ugli fruit is a hybrid of grapefruit, orange, and tangerine, known for its mild flavor and easy-to-peel skin. 


Citrus fruits offer a range of health benefits due to their nutritional content, including:

  • High in Vitamin C: Citrus fruits are renowned for their high vitamin C content, which is essential for a healthy immune system. Vitamin C also acts as an antioxidant, protecting cells from damage by free radicals.
  • Rich in Fiber: Citrus fruits contain dietary fiber, which supports digestive health by promoting regularity and preventing constipation. Fiber also helps lower cholesterol levels and may reduce the risk of heart disease. The fiber content in citrus fruits can help promote feelings of fullness. 
  • Antioxidant Properties: Citrus fruits contain various antioxidants, including flavonoids and carotenoids, which help reduce inflammation and oxidative stress in the body. These antioxidants may lower the risk of chronic diseases such as heart disease, cancer, and neurodegenerative disorders.
  • Heart Health: The potassium content in citrus fruits can help regulate blood pressure levels, reducing the risk of hypertension and stroke. Additionally, the fiber and antioxidants in citrus fruits may lower cholesterol levels and improve heart health.
  • Skin Health: Vitamin C plays a crucial role in collagen synthesis, which is essential for maintaining healthy skin. Citrus fruits’ antioxidant properties also help protect the skin from external damage. 
  • Cancer Prevention: Some studies suggest that the antioxidants found in citrus fruits may help prevent certain types of cancer by neutralizing free radicals and inhibiting the growth of cancer cells.
