Purpose: The aim of the study was to investigate the influence of cooking methods on the nutritional content of vegetables in Kenya.

Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.

Findings: Cooking methods can affect the nutritional content of vegetables. Boiling may lead to the loss of water-soluble vitamins, while steaming and microwaving are better for retaining them. Fiber remains relatively stable during cooking. Antioxidants may be preserved or enhanced by steaming and sautéing. Some minerals are stable, while others like calcium and iron may be affected by cooking. Phytochemicals' availability can vary with cooking methods. Shorter cooking times and minimal water use are generally better for nutrient retention. Personal taste and preferences also play a role in choosing cooking methods.

Implications to Theory, Practice and Policy: Maillard reaction theory, heat transfer theory and nutrient bioavailability theory may be use to anchor future studies on the influence of cooking methods on the nutritional content of vegetables in Kenya. Promote culinary education and awareness of a diverse range of cooking techniques. Encourage individuals to experiment with various methods to find the most suitable ones for different vegetables, taking into account their specific nutritional goals and taste preferences. Advocate for clear and informative nutrition labeling on food products.

Effect of Dietary Fiber Intake on Blood Sugar Levels in Kenya

Purpose: The aim of the study was to investigate the effect of dietary fiber intake on blood sugar levels in Kenya.

Findings: Studies on dietary fiber intake in Kenya suggest that higher fiber consumption is linked to better blood sugar control, reduced glycemic responses, and improved insulin sensitivity. Traditional Kenyan diets, rich in fiber from whole foods like grains, legumes, fruits, and vegetables, play a significant role in promoting these health benefits. These findings emphasize the potential of dietary fiber in managing blood sugar levels and preventing diabetes in Kenya, highlighting the importance of encouraging fiber-rich dietary patterns in public health strategies.

Implications to Theory, Practice and Policy: The glycemic index (GI) theory, the gut microbiota theory and the insulin resistance theory may be use to anchor future studies on the effect of dietary fiber intake on blood sugar levels in Kenya. Promote Dietary Education: Healthcare practitioners should prioritize dietary education and guidance for individuals with type 2 diabetes or those at risk. Policymakers should consider integrating specific recommendations on fiber intake into national dietary guidelines.

Impact of Omega-3 Fatty Acid Supplementation on Cardiovascular Health

Purpose: The aim of the study was to investigate the impact of omega-3 fatty acid supplementation on cardiovascular health.

Findings: Omega-3 fatty acid supplementation has a positive impact on cardiovascular health by reducing the risk of heart attacks and strokes, lowering blood pressure, improving lipid profiles, and providing anti-inflammatory and anti-arrhythmic effects. It is particularly beneficial for individuals with heart conditions. However, dosages matter, and individual health factors should be considered before starting supplementation.

Implications to Theory, Practice and Policy: Inflammation theory, lipid theory and platelet aggregation theory may be use to anchor future studies on the impact of omega-3 fatty acid supplementation on cardiovascular health. Develop and update clinical guidelines that provide clear recommendations for healthcare practitioners regarding the appropriate use of Omega-3 fatty acid supplementation in various patient populations. Regulation and Quality Control: Advocate for stringent regulation and quality control measures within the supplement industry.

Relationship between Vitamin D Intake and Bone Density in Elderly Individuals

Purpose: The aim of the study was to investigate relationship between vitamin D intake and bone density in elderly individuals.

Findings: The relationship between vitamin D intake and bone density in elderly individuals is well-established. Low vitamin D levels are associated with reduced bone density, and supplementation can help improve it, especially in cases of deficiency. The ideal dosage and individual responses vary, and factors like calcium intake, sunlight exposure, and overall health also play a role in maintaining bone density in the elderly.

Implications to Theory, Practice and Policy: Calcium homeostasis theory, hormonal regulation theory and bone remodeling theory may be use to anchor future studies on the relationship between vitamin D intake and bone density in elderly individuals. In clinical practice, consider personalized vitamin D supplementation regimens based on individual needs, taking into account factors such as age, gender, dietary habits, and geographical location. Develop evidence-based national or international guidelines for vitamin D intake and supplementation specific to elderly populations.

Effects of a Mediterranean Diet on Weight Loss in Obese Individuals

Bonface Kimani — Sun, 18 Feb 2024 00:00:00 +0300

Purpose: The aim of the study was to investigate the effects of a Mediterranean diet on weight loss in obese individuals.

Findings: The Mediterranean Diet consistently leads to significant weight loss in obese individuals, while simultaneously improving their overall health. This dietary pattern is not only effective but also evidence-based for obesity management. It goes beyond just shedding excess pounds, offering additional benefits such as improved cardiovascular health, reduced risk factors for heart disease, better body composition, lower inflammation, and decreased susceptibility to obesity-related diseases.

Implications to Theory, Practice and Policy: Theory of health behavior change, social cognitive theory and theory of planned behavior may be use to anchor future studies on the effects of a Mediterranean diet on weight loss in obese individuals. Healthcare practitioners and nutritionists should consider tailoring Mediterranean Diet plans to individual needs and preferences. Public health policymakers should implement educational campaigns to raise awareness about the Mediterranean Diet's benefits and promote its adoption.
