Grandma Knew Best: New Study Shows Traditional Ghanaian Diet Slashes Kidney Disease Risk

Published

on

ACCRA – The leafy green stews, whole-grain porridges, and vegetable-rich soups that have sustained Ghanaian families for generations may be doing far more than filling bellies. A new study suggests they could be saving kidneys.

Research published on May 26, 2026, in Scientific Reports, a journal within the Nature portfolio, has found that Ghanaians who eat a highly pro-inflammatory diet face more than six times the risk of developing chronic kidney disease (CKD) compared to those who consume anti-inflammatory foods. The traditional Ghanaian diet—rich in vegetables, fruits, and whole grains—is inherently anti-inflammatory, researchers say.

The findings come as kidney disease incidence rises steadily across Ghana, with some health experts pointing to a gradual dietary transition away from traditional eating patterns toward Westernized foods high in saturated fats and simple sugars.

A Striking Disparity Between the Sick and the Healthy

The study, led by Antwi Joseph Barimah of the College of Health at Yamfo, enrolled 200 participants at the Korle-Bu Teaching Hospital between August and October 2022, dividing them equally into a CKD group and a healthy control group.

Researchers calculated a Dietary Inflammatory Index (DII) score based on 29 dietary parameters, including fats, carbohydrates, proteins, fibre, vitamins, and even tea and onion consumption.

The results were striking. While 20 percent of all participants fell into the highest pro-inflammatory diet category, the disparity between the sick and the healthy was enormous. Thirty-one percent of those with CKD consumed a highly pro-inflammatory diet, compared to just nine percent of the healthy control group.

Conversely, 38 percent of healthy participants ate a strongly anti-inflammatory diet, while only two percent of kidney disease patients did so.

Six Times the Risk

The dose-response relationship proved equally alarming. As dietary inflammatory scores rose, so did the odds of kidney disease.

Participants in the third quintile of pro-inflammatory eating were nearly three times more likely to have CKD than those in the lowest category. Those in the fourth quintile faced a fivefold increase in risk. And individuals in the highest pro-inflammatory quintile saw their odds skyrocket by more than six times—even after researchers controlled for major confounding factors including age, sex, hypertension, and diabetes.

“What we are seeing is a clear, powerful association between what Ghanaians eat and their kidney health,” the research team concluded.

The Shift Away from Traditional Foods

The authors pointed to a worrying trend in Ghanaian eating habits. The traditional diet—abundant in leafy vegetables like kontomire and ayoyo, legumes, whole grains such as millet and sorghum, and fruits—is naturally rich in anti-inflammatory compounds.

However, a shift toward Westernized eating patterns, characterized by processed foods, saturated fats, simple sugars, and excessive protein, appears to be fueling systemic inflammation. That inflammation, the researchers note, plays a critical role in the development of kidney disease in all its forms.

Interestingly, the study revealed that participants with kidney disease reported significantly higher protein intake than healthy controls, despite clinical guidelines recommending moderated protein consumption for non-dialysis patients. The authors noted that dietary restrictions are notoriously difficult to maintain in real-life situations.

A Call for Cultural and Clinical Change

Barimah and his colleagues have recommended that healthcare providers at Korle-Bu and similar facilities incorporate DII scoring into routine screening for patients at risk of CKD. They have also called for nutrition counselling to emphasize anti-inflammatory eating patterns—specifically, a return to traditional Ghanaian foods.

That means increasing intake of fruits, vegetables, whole grains, and healthy fats while reducing processed foods high in saturated fats. The team further advocated for more active integration of dietitians into renal care teams to guide individualized dietary interventions.

For ordinary Ghanaians, the message is simpler: the foods grandmother served may have been protecting more than just cultural heritage.

Study Limitations

The study acknowledged certain limitations, including non-probability sampling, which may limit generalisability, and the potential for recall bias inherent in food frequency questionnaires. Some kidney disease patients, having received prior dietary counselling, may have reported a healthier intake than they actually consumed.

The authors recommended that future research employ alternative, less subjective dietary assessment methods. The study was approved by the Scientific and Technical Committee of the Korle-Bu Teaching Hospital, and all participants provided informed signed consent. The authors declared no competing interests and confirmed that no external funding was received.

Hopeful News

As Ghana grapples with rising healthcare costs and an increasing burden of non-communicable diseases, this research offers a rare piece of hopeful news. One of the most powerful tools to prevent chronic kidney disease may already be sitting on Ghanaian dinner tables; if families choose to keep it there.

Yaa Naa Mahama Abukari II: Influential Traditional Ruler Who Restored Peace to Dagbon After 16-Year Dispute Dies

Published

on

Yaa Naa Mahama Abukari II, the traditional king (Overlord) of Dagbon in northern Ghana, has died.

Enskinned in January 2019, he played a central role in ending a long-running 16-year chieftaincy dispute between two royal factions that had divided the kingdom and disrupted traditional activities for years.

Born Bukali in Mion, the late king began his leadership journey as chief of Kpunkpono before ascending to the influential Savelugu skin.

His selection as Yaa Naa marked a historic moment of reconciliation in Dagbon, one of Ghana’s most important traditional kingdoms.

His passing, confirmed by multiple credible sources on Monday, July 13, is expected to trigger widespread mourning across the region, with many reflecting on his contributions to peace and the restoration of stability in northern Ghana.

Yaa Naa’s Legacy

Ascending to the throne as the 41st Overlord (or 42nd by some regional counts) in January 2019, his brief but transformative reign brought stability back to one of Ghana’s oldest and most influential traditional kingdoms.  

The core pillars of his legacy include:

  1. The Restoration of Peace and Reconciliation
    The defining achievement of his reign was ending the deeply polarizing, 17-year-long Dagbon chieftaincy dispute.  

Following the tragic 2002 assassination of his predecessor, Yaa Naa Yakubu Andani II, the kingdom was fractured into two rival royal gates: the Abudus and the Andanis.  

Working alongside the government-backed Committee of Eminent Chiefs, his enskinment in 2019 healed these generational wounds. He successfully united both factions, restoring the moral and spiritual authority of the skins of Yendi and bringing long-awaited political stability to Northern Ghana.  

  1. Institutional and Constitutional Reforms
    Yaa Naa Mahama Abukari II recognized that lasting peace required strong legal frameworks.

In 2020, he initiated a comprehensive review of the Dagbon Constitution to clarify customary successions and prevent future royal disputes.  

Under his guidance, the revised constitution was formally adopted by the Dagbon Traditional Council in 2022, providing a clear roadmap for future generations.

  1. Socio-Economic and Cultural Development
    He actively worked to move Dagbon away from conflict and toward regional prosperity.  

Dagbon Development Fund (DDF): Launched in 2021, this fund was designed to channel resources directly into economic development, healthcare, and educational infrastructure across the kingdom.  

Gbewaa Palace Redevelopment: In March 2023, he initiated the physical reconstruction and modernization of the historic Gbewaa Palace in Yendi, a symbolic rebuilding of the kingdom’s beating heart.  

International Partnerships: He championed human capital growth by facilitating institutional collaborations, such as the 2024 educational partnership between Tamale Technical University (TaTU) and Bursa Technical University in Turkey.  

  1. Humanitarian and National Leadership
    As the President of the Northern Regional House of Chiefs, he extended his influence far beyond his immediate kingdom to foster national unity.  

He was highly regarded for his philanthropy, notably sending substantial agricultural relief (including hundreds of bags of maize, rice, and yams) to help communities displaced by the devastating 2023 Volta Region floods and parts of the Savannah Region.  

Ultimately, Yaa Naa Mahama Abukari II went from a quiet, respected regional chief of Savelugu to the “Lion of Gbewaa” who chose healing over division. He leaves behind a peaceful, structured, and forward-looking Dagbon Kingdom.

‘Don’t Blame Migrants’: UN Warns South Africa as ‘Cruel’ Deportations Surpass 53,000

Published

on

The United Nations has issued a sharp warning against using migrants as scapegoats for South Africa’s socioeconomic challenges, as the government confirmed that more than 53,000 foreign nationals have been deported or repatriated in just five weeks.

Justice and Constitutional Development Minister Mmamoloko Kubayi announced on Sunday that 53,499 foreign nationals have been processed for deportation and voluntary repatriation since the launch of a nationwide “migration management” campaign in mid-June.

The crackdown, one of South Africa’s largest in years that many across the world are condemning as cruel and inhumane, follows weeks of anti-immigration protests marked by violence, intimidation, and looting.

Malawians Bear the Brunt

According to official figures, Malawian citizens accounted for over 80 percent of those processed, followed by nationals from Zimbabwe and Mozambique. The Temporary Repatriation Processing Centre in Musina, Limpopo Province, has processed nearly 2,500 people, most of them Malawian and Zimbabwean nationals. Several countries, including Ghana, Nigeria, Uganda, and Kenya, have flown their citizens home in recent weeks.

UN: Migrants Are Not the Problem

The UN has cautioned against conflating migration with South Africa’s deep-rooted challenges of unemployment, inequality, and service delivery failures. Anti-migrant activists have accused undocumented foreigners of driving crime and taking jobs, but the UN and civil society groups argue that foreign workers—who make up only about 5 percent of the population—are being unfairly scapegoated.

“Now, in what universe can you scapegoat 4% to 5% of the population for all our problems?” economist Duma Gqubule said recently, dismissing the anti-migrant stance as “mass hallucination”.

Organizations defending migrants’ rights emphasize that foreign workers have become convenient targets in a country where the unemployment rate exceeds 30 percent and disproportionately affects Black South Africans.

Vigilante Threats and a “Deadline” That Passed

Anti-migrant activists had set an unofficial 30 June deadline for all undocumented migrants to leave the country, prompting thousands to flee in fear. Protesters—including leaders from groups such as March and March—have threatened to stage weekly demonstrations until the government meets their demands. There are mounting fears that the protests could turn violent again.

President Cyril Ramaphosa has acknowledged public concerns about immigration but has condemned attacks against migrants and warned citizens against taking the law into their own hands. Minister Kubayi also cautioned that protesters must not conduct unauthorised searches of homes and businesses suspected of sheltering undocumented migrants.

Government Defends Enforcement, Signals Scaling Down

Kubayi said the deportation process has helped authorities apprehend individuals wanted for criminal activity, and that the government remains committed to “observing human rights and dignity of all people in our country, irrespective of their citizenship”. She added that authorities will continue enforcing immigration laws.

However, the government is reportedly considering scaling back the campaign as the number of repatriations increases.

“We envisage a phased scaling down of the process which will not negatively impact or compromise the deportation and repatriation processes we are undertaking,” a government source told Business Day.

Diplomatic Fallout

The crackdown has strained regional relations.

Ghana postponed a state visit by President Ramaphosa following xenophobic rallies that resulted in hundreds of Ghanaians being repatriated.

Other African nations have similarly expressed concern, with some leaders accusing South Africa of failing to protect foreign nationals.
