Like many other legumes, black beans contain starch, a complex carbohydrate. Starch acts as a slow-burning energy reserve, and therefore is digested slowly by the body, preventing sudden spikes in blood sugar levels.

Black beans are good for health, but some people need to limit their consumption.

Who should avoid eating black beans?

An article about black beans by Dr. Huynh Tan Vu in the Health & Life newspaper states that no food is perfect, and no medicine can cure all diseases. We need to be cautious when consuming black beans regularly.

A varied diet is necessary; consuming black beans continuously for extended periods is not good for health. Regarding blood pressure, black beans contain low levels of sodium, which is beneficial.

Black bean water should only be consumed as a refreshing beverage, 2-3 times a week, about 100-250ml each time, just enough to avoid feeling full. Do not use black bean water as a replacement for your daily water intake, as it can affect your body's ability to absorb nutrients.

Black bean water should be drunk plain, without added sugar. People with diabetes should not add sugar to black bean water. Black bean water has a diuretic effect, so people with kidney disease should use it with caution.

The ideal time to consume black beans with other foods is about 4 hours apart. Black beans contain phytates, which can affect the body's ability to absorb nutrients. Phytates hinder the absorption of minerals such as iron, zinc, copper, and phosphorus (black bean water should not be used to take medications containing iron, zinc, calcium, copper, or calcium, or to consume foods containing these substances).

People with colitis, loose stools, diarrhea, or poor digestion should not consume black beans. The high protein content in black beans makes it difficult for the elderly, children, or those with weak constitutions to fully digest the protein. Drinking black bean water can easily cause digestive problems, bloating, and abdominal pain.

In reality, no food is perfect, and no medicine is a panacea. Black beans are no exception.

When experiencing health problems, patients need to thoroughly investigate the causes and proactively adjust their lifestyle and exercise habits. They should seek examination, treatment, and advice from experts and doctors with knowledge and experience instead of believing and applying unverified information on social media.
