A low-red and processed meat diet was found to have a positive impact on blood pressure in individuals with type 2 diabetes when compared to the typical diabetic diet. However, the diet did not significantly affect blood glucose control and lipid profile factors.

Type 2 diabetes leads to serious health issues if not properly managed. Lifestyle modifications, such as dietary interventions, play a crucial role in managing this condition to prevent complications. In recent years, there has been a growing interest in the role of diet in maintaining health and preventing chronic diseases. One area of focus has been the consumption of red and processed meat, which has been linked to an increased risk of cardiovascular disease, diabetes, and cancer.

A recent study published in Nutrition Journal indicates that the LRALD may have a positive effect on blood pressure in individuals with type 2 diabetes when compared to a typical diabetic diet. However, no significant effects were observed in terms of blood glucose control and lipid profile improvements.

The LRALD and Control Group

Eighty participants were randomly assigned to either the LRALD group or the control group, with 70 completing the study. The LRALD group was instructed to limit their red and processed meat intake to one serving per week, while the control group continued with their regular diet. The study followed both groups for 12 weeks.

Vitamin A and Dietary Fiber in Comparison With Control Group

The LRALD group had a significantly higher intake of vitamin A and dietary fiber compared to the control group. Vitamin A is important for maintaining healthy skin, vision, and immune function, while dietary fiber is essential for maintaining digestive health.

The study also measured the potential acid load of the participants’ diets using two indicators: potential renal acid load (PRAL) and net endogenous acid production (NEAP). These indicators are used to assess adherence to the LRALD, as the diet is designed to be low in acid-producing foods. The results showed that the LRALD group had significantly lower PRAL and NEAP values compared to the control group. 

LRALD Diet Was Effective in Improving Key Health Parameters

The study also measured a number of health parameters before and after the 12-week intervention. The primary outcomes showed that both groups had significant reductions in fasting blood glucose and HbA1C. In the LRALD group, diastolic blood pressure was significantly reduced after the intervention. 

These findings suggest that the LRALD may be effective in improving certain health parameters compared to a typical diet.
