Mulberry supports the heart and liver

Konkonte fights Colon Cancer, lowers Blood Sugar-Study

Mulberry has some interesting history. For instance, there is this story of Pyramus and Thisbe. In this story, two next-door neighbors turned lovers were forbidden from getting married because of their parents’ rivalry. However, they arrange to meet under a mulberry tree to confess their love. But due to a misunderstanding, Pyramus believes Thisbe was killed by a lion and ends up stabbing himself like Romeo and Juliet style with his red blood staining the white mulberries.

In fact, in the 17th century, King James I imported 100,000 mulberry trees from all over Europe in hopes of increasing silk production in Great Britain. However, his project failed when he accidentally ordered black mulberries instead of the white mulberries that produce the leaves eaten by silkworms.

This was supported by Imran et al. (2010) study which asserts that the trees are traditionally grown for their leaves mainly in Asia and North America as they’re the only food that silkworms eat.   Mulberries can be found in wine, fruit juice, tea, jam, or canned foods, but can also be dried and eaten as a snack. They have now gained popularity globally (Calín-Sánchez et al.2013) due to their sweet flavor, impressive nutritional value, and various health benefits.

Today, some cities in North America have actually banned the growth of mulberry trees because of the large amount of pollen they produce. Interestingly enough, the male trees produce pollen while female trees grow flowers that draw pollen and dust from the air.

Nutrition Facts

Fresh mulberries have  88% water and only  60 calories per cup (140 grams). By fresh weight, they provide 9.8% carbs, 1.7% fiber, 1.4% protein, and 0.4% fat. Mulberries are often consumed dried, similar to raisins. In this form, they contain 70% carbs, 14% fiber, 12% protein, and 3% fat — making them fairly high in protein compared to most berries.

According to US Department of Agriculture, to be accessed One cup of mulberries contains approximately:

  • 2 calories
  • Water:88%
  • 7 grams carbohydrates
  • 2 grams protein
  • 5 gram fat
  • 4 grams dietary fiber
  • 51 milligrams vitamin C (85 percent Daily value (DV)
  • 9 micrograms vitamin K (14 percent DV)
  • 6 milligrams iron(14 percent DV)
  • 272 milligrams potassium (8 percent DV)
  • 1 milligram riboflavin (8 percent DV)
  • 2 milligrams vitamin E (6 percent DV)
  • 2 milligrams magnesium (6 percent DV)
  • 2 milligrams phosphorus (5 percent DV)
  • 6 milligrams calcium (5 percent DV)

Studies on Health Benefits

Averts Cancer

Due to their extraordinary antioxidants, one study by Sakagami et al., (2007) found that mulberry juice was able to effectively reduce levels of oxidative damage caused by free radicals in mice.

Another retrospective similar animal study by Sakagami et al. (2006) found that mulberry juice acted as an antioxidant and reduced stress caused by these cancer-causing free radicals.

Fast-forward, a study by Cho et al. (2017), isolated a specific compound from mulberries and found that it was able to induce cell death in breast cancer cells and slow the growth and spread of tumor cells in mice.

Weight Loss

One retrospective study by Stephen and Cummings (1980) found that one cup of mulberries can add 10 percent of daily fiber needs.  The study notes that fiber adds bulk to stool and enhances satiety, keeping you feeling fuller for longer to reduce appetite. A prospective study by Peng et al. (2011) agrees that mulberries could have an anti-obesity effect.  The study demonstrates that treating hamsters with mulberry water extract for 12 weeks lowered both body weight and visceral fat.

Cholesterol Levels

Ruggeri (2019) agrees that the fiber found in mulberries is mostly insoluble fiber, “but it also contains about 25 percent soluble fiber in the form of pectin”. Additionally, a study by Imran et al.(2010) found that  soluble fiber can absorb water and help reduce cholesterol levels and decrease the risk of heart disease.

One retrospective study by Liu et al. (2008) demonstrates the weight loss effect of mulberry. This is done by engineering the compounds in mulberry to avert the oxidation of LDL cholesterol, one of the major risk factors of heart disease.  In this animal study, mulberry water extract helped decrease levels of both triglycerides and cholesterol.

 Liver Health

Some studies agree that Mulberries may be especially effective in the prevention of fatty liver disease.  For instance, Chang et al. (2013) study which involves a test-tube found that the compounds in mulberries helped block fat formation, prevented fat accumulation and also promoted the clearance of fat out of the liver.

Interestingly, one retrospective study by Ou TT et al.(2011) is in agreement and found that mulberry extract increased fat breakdown and decreased fatty acid formation.

Blood Sugar Levels

One study by Wang et al. (2013) in PLoS One agrees that mulberry extract was able to significantly lower blood sugar levels in diabetic mice.

A similar study by Stefănuţ et al. (2013), where diabetic rats were given mulberry extract for five weeks, and their blood sugar was measured after. The study found that, the diabetic rats blood sugar dropped from 252 mg/dL to 155 mg/dL.


Although minimal, there are some allergic reaction. For instance, one study by Choi et al. (2015) found reactions in those who are sensitive to birch pollen due to cross-reactivity.  This means that, discontinue use if you experience any mulberry fruit side effects.

This notwithstanding, for most people without sensitivities, mulberries can be a nutritious addition to the diet and can come with many benefits to health. Moderation is always the key thing to do (Links, 2019).

Take Home

In conclusion, studies demonstrate that mulberry fruits avert cancer, reduce cholesterol and blood sugar levels, aid in weight loss, and protect the health of your liver.
