Introduction:

Local cultural practices, particularly those related to food preparation, can significantly influence health outcomes. In Makassar, a traditional and culturally-rooted practice involves cooking meals using periuk tanah (earthenware pots). These clay pots are not only valued for their aesthetic and historical significance, but are also believed to preserve the natural flavor, aroma, and nutritional quality of food through slow and even heat distribution (Setiawan et al., 2020). Unlike modern cookware that often involves synthetic materials and high-temperature exposure, earthenware cooking retains more of the food’s moisture and essential nutrients, which can positively affect digestive health, mineral retention, and glycemic control.

Recent interest has emerged around the potential health benefits of these traditional practices, especially as non-communicable diseases such as type 2 diabetes, hypertension, and cardiovascular diseases continue to rise across Indonesia (Rahim & Yusuf, 2021). Preliminary studies have suggested that cooking in earthen pots may lead to lower levels of unhealthy fats, reduced glycation end-products, and enhanced taste perception, which may improve dietary adherence among individuals with chronic conditions. Moreover, food prepared in clay pots may exhibit lower pH shifts and better preservation of antioxidants, contributing to anti-inflammatory effects.

Beyond nutritional and metabolic outcomes, this practice also carries important sensory implications. Meals cooked in periuk tanah are reported to have a richer, more authentic flavor and aroma profile, which may enhance appetite and mealtime satisfaction, particularly among the elderly and patients recovering from illness. These sensory benefits might indirectly support better nutrient intake and psychological well-being, highlighting the interplay between culture, sensory experience, and health.

This study aims to investigate the physiological impacts (including blood lipid profile, glycemic levels, and electrolyte balance) and sensory outcomes (such as flavor, texture, and aroma ratings) associated with the use of periuk tanah in daily meal preparation. By examining this local health-related policy rooted in cultural wisdom, the research seeks to validate traditional knowledge through scientific inquiry and explore its relevance for community-based interventions, chronic disease management, and health promotion strategies within the broader framework of culturally competent care.

Methods
This experimental study was conducted over a 12-month period in 2023 and involved a purposive sample of 400 families residing in rural communities of Makassar, South Sulawesi. These families were selected based on specific inclusion criteria, notably their long-standing, consistent use of periuk tanah (earthenware pots) for the daily preparation of staple meals such as rice and fish—two core components of the traditional South Sulawesi diet. The selection aimed to ensure that the observed outcomes could be attributed with higher confidence to the use of this traditional cooking method rather than other confounding lifestyle factors.

To evaluate the health impacts of this cooking practice, participants underwent comprehensive monthly health evaluations, conducted by trained healthcare personnel. These assessments included both laboratory-based tests and clinical physical examinations. The laboratory tests comprised measurements of High-Density Lipoprotein (HDL) cholesterol as a marker of cardiovascular health, Hemoglobin (Hb) to assess oxygen-carrying capacity and nutritional status, Fasting Blood Glucose (FBG) as an indicator of metabolic function and diabetes risk, and electrolyte panels (including sodium, potassium, and chloride) to evaluate fluid balance and renal function.

In addition to laboratory analyses, vital signs were recorded monthly, including systolic and diastolic blood pressure, pulse rate, respiratory rate, and body temperature. These parameters were chosen to reflect both baseline physiological status and any potential changes that might result from dietary shifts related to traditional cooking methods. Consistent monthly follow-ups allowed for the observation of health trends over time, enabling early detection of physiological improvements or risks.

The study employed a community-based participatory research (CBPR) approach, emphasizing collaboration with local leaders and health workers to build trust, promote adherence, and ensure that cultural values were respected throughout the research process. Participants were also educated about the purpose of the study and their rights, including the option to withdraw at any stage without penalty.

Importantly, ethical approval was secured from the Local Health Research Ethics Board of Makassar (Approval No. 2023/ETIK-RS/089), in accordance with the Declaration of Helsinki. Informed consent was obtained from all participating families, and data confidentiality was maintained throughout the study. The ethical considerations extended to respecting cultural norms, dietary habits, and the use of non-invasive

procedures wherever possible.

By documenting both clinical and biochemical outcomes, this study sought to generate robust evidence on the potential preventive and therapeutic roles of culturally embedded practices, such as cooking with earthenware pots, in enhancing family health, preventing chronic diseases, and supporting local health policies grounded in indigenous wisdom.

Results
The results of the 12-month experimental study demonstrated notable improvements in metabolic, hematological, and physiological parameters among participants who consistently utilized periuk tanah (earthenware pots) for daily cooking. The findings underscore the potential of local food preparation methods in promoting better health outcomes, particularly in rural communities with limited access to modern healthcare.

Analysis and Interpretation

• HDL Cholesterol showed a statistically significant increase (p < 0.01), indicating an improvement in cardiovascular health possibly linked to the reduction in cooking oil oxidation and retention of natural fatty acids when using periuk tanah (Rahim & Yusuf, 2021; Sharma et al., 2019).
• Hemoglobin normalization in 85% of participants previously diagnosed with mild anemia suggests better iron absorption or reduced dietary contamination, potentially due to lower heavy metal leaching compared to aluminum or non-stick cookware (Patel et al., 2018).
• FBG stabilization with an average of 92 mg/dL across the sample reflects improved glycemic control, which may be related to slower carbohydrate breakdown due to uniform heat distribution and enhanced fiber retention in food (Chung et al., 2020).
• Electrolyte balance (Na⁺, K⁺, Cl⁻) remained within reference values at all monthly checkpoints, suggesting that dietary sodium intake and renal function were unaffected, confirming the safety of long-term use of earthen pots with respect to mineral balance (WHO, 2021).
• Vital signs such as systolic/diastolic blood pressure (average 118/76 mmHg), pulse rate (72 bpm), respiratory rate (18 breaths/min), and body temperature (36.7°C) were maintained within normal physiological ranges, indicating overall homeostatic stability and no signs of stress or inflammation attributable to dietary sources.

These findings highlight the therapeutic potential of culturally grounded dietary practices and support the integration of such approaches in community-level health promotion programs, especially in rural or underserved regions.

Discussion
The use of earthenware (clay) pots in culinary traditions, particularly in Makassar, is not only a cultural hallmark but also potentially a natural health-enhancing practice. These cooking vessels, made from natural clay, have been found to release trace minerals such as calcium, magnesium, iron, and phosphorus into food during prolonged heating, especially in moist cooking environments (Kumar et al., 2019). These minerals are essential for maintaining electrolyte balance, red blood cell function, and enzymatic activity, particularly in populations that rely heavily on staple-based diets with limited food variety.

Furthermore, clay pots are naturally porous and can retain moisture, which leads to slower evaporation of water and preservation of water-soluble nutrients like B-vitamins and certain antioxidants (Singh & Meena, 2020). This method of cooking at lower, more consistent temperatures reduces the degradation of heat-sensitive nutrients, in contrast to the nutrient losses that often occur with high-temperature metal cookware (Gibson et al., 2021).

Another key benefit lies in the avoidance of synthetic chemical exposure. Conventional non-stick cookware often contains perfluorooctanoic acid (PFOA) and other fluoropolymer coatings, which have been linked to endocrine disruption, liver toxicity, and possible carcinogenic effects (Zhou & Wang, 2022; US EPA, 2021). By using traditional clay pots, communities may reduce long-term exposure to harmful industrial compounds that leach into food during high-heat cooking.

The findings from this study lend support to earlier ethnographic research that suggested health benefits associated with traditional food preparation techniques in Makassar. For example, Rahim & Yusuf (2021) noted that families adhering to ancestral cooking practices exhibited lower incidences of gastrointestinal and metabolic disorders, which may be related to both the physical characteristics of the cooking vessel and the slower, communal style of food preparation and consumption.

Moreover, clay pot cooking is energy-efficient, as it retains heat longer and requires less fuel, aligning with sustainable health and environmental goals (UN FAO, 2019). Its reintroduction and promotion as part of public health policy may serve as a culturally respectful, cost-effective, and non-pharmacological strategy to support chronic disease prevention, particularly in rural and peri-urban populations in Southeast Asia.

Conclusion
The Makassar community's use of earthenware for cooking is more than a cultural artifact—it is a functional health strategy. This traditional practice not only elevates food taste but also contributes to meaningful physiological health improvements.
