Combination therapy of bioactive compounds with acarbose: A proposal to control hyperglycemia in type 2 diabetes.

Type 2 diabetes (T2D) is a chronic metabolic disease with a high impact on public health and social welfare. Hyperglycemia is a characteristic of T2D that leads to different complications. Acarbose (ACB) reduces hyperglycemia by inhibiting α-amylase (AMY) and α-glucosidase (GLU) enzymes. However, ACB causes low adherence to treatment by patients with diabetes due to its side effects. Consequently, reducing the side effects produced by ACB without compromising its efficacy is a challenge in treating T2D. Bioactive compounds (BC) are safe and could decrease the side effects compared to antidiabetic drugs such as ACB. Nevertheless, their efficacy alone concerning that drug is unknown. The scientific advances have been directed toward searching for new approaches, such as combination therapies between BC and ACB. This review analyzes the combined therapy of BC (extracts or isolates) with ACB in inhibiting AMY and GLU as a proposal to control hyperglycemia in T2D. PRACTICAL APPLICATION: Postprandial hyperglycemia is one most typical signs of type 2 diabetes, and it can have significant consequences, including cardiovascular problems. Acarbose has side effects that lead to the abandonment of treatment. Bioactive compounds in extracts or isolated forms have become a viable option for controlling hyperglycemia without side effects, but their administration alone is insufficient. The scientific advances of acarbose/bioactive compound combination therapy as a proposal for controlling hyperglycemia in T2D were analyzed. The findings suggested that bioactive compounds combined with acarbose are effective when they function synergistically or additively; however, they are not recommended in therapy when they have an antagonistic effect.

A study on nutritional and functional study properties of Mayan plant foods as a new proposal for type 2 diabetes prevention.

Mayan communities cultivate a great variety of plant foods that could be of interest due to their nutritional and functional potential. The aim of this study was to evaluate the nutritional value, glycemic index (GI), total phenol content (TPC), and total flavonoid content (TFC), and in vitro antioxidant and antidiabetic activity of 24 plant foods of a Mayan community from the Yucatan Peninsula. Multivariate statistical analysis indicated that Psidium guajava L. (fruit), Cucurbita moschata (vegetable), Raphanus sativus L. (tuber), Brassica oleracea var. capitata L. (leaf), and Bixa orellana L. (seed) had the highest nutritional and functional value for each plant food group. Principal component analysis suggested that TFC is a key feature to select plant foods with antidiabetic potential. Mayan plant foods have nutritional and functional properties that can be used in the development of a new proposal aimed at preventing type 2 diabetes.

Foods from Mayan Communities of Yucatán as Nutritional Alternative for Diabetes Prevention.

The increase in the prevalence of diabetes has become a severe problem around the world; mainly affecting indigenous communities as the Mayan of Yucatán in Mexico. Because of the high rates of poverty and insufficient health services in this ethnic group, inexpensive and accessible treatments are necessary. Some plant foods grown in traditional Mayan agricultural systems have antidiabetic potential. Our objective was to present a review of plant foods with nutritional alternatives for diabetes prevention from traditional agricultural systems in Mayan communities of Yucatán. This review reports the hypoglycemic, antihyperglycemic, and antidiabetic activities of leaves, fruits, vegetables, grains and legumes, and tubercles grown in milpas and home gardens of Mayan communities. Some plant foods have antidiabetic effect in vitro, in vivo, and in clinical studies. Some plant foods grown in traditional Mayan agricultural systems have antidiabetic potential. The inclusion of these plant foods in the diet can serve in the treatment of diabetes.
