Healthy Plant Based Diets Could Help Reduce The Risk Of Diabetes F

Research has found that consuming healthy plant-based foods, which include vegetables, fruits, legumes, nuts, and coffee is linked to a reduced risk of type 2 diabetes in normally healthy individuals.1✅ JOURNAL REFERENCE

The study focused on identifying the metabolite profiles associated with various plant-based diets and investigating possible links between those profiles and type 2 diabetes risk.

A metabolite is a substance produced or used by a living organism’s chemical processes and includes the multitude of compounds in various foods and also the complex array of molecules created when the body breaks down and transforms those compounds.

The chemical composition of different foods means that a person’s diet should be represented in their metabolite profile. Metabolomics is characterized as the extensive analysis and identification of all the different metabolites found in a biological sample.

The worldwide type 2 diabetes health burden is increased even more by the many macrovascular complications as a result of the condition, such as cardiovascular disease, as well as microvascular complications, which damage the nervous system, the eyes, and the kidneys.

The diabetes epidemic is largely a result of an unhealthy diet, being obese or overweight, genetically predisposed, and other lifestyle factors which include insufficient exercise.

Plant-based diets, particularly healthy ones abundant in high-quality foods that include vegetables, fruits, and whole grains, have been linked to a reduced risk of type 2 diabetes but the underlying mechanisms involved aren’t well understood.

The researchers carried out an analysis of dietary intake and blood plasma samples of 10,684 participants who were mostly white, middle-aged with an average age of 54, and with an average BMI of 25.6kg/m2.

Questionnaires on food frequency were completed which were scored based on the participant’s adherence to 3 plant-based diets classified as a general Plant-based Diet Index, a healthy Plant-based Diet Index, and an unhealthy Plant-Based Diet Index.

Diet indices were determined by that person’s intake of 18 food groups: healthy plant foods such as vegetables, fruits, whole grains, legumes, nuts, vegetable oils, and coffee or tea; unhealthy plant foods such as potatoes, refined grains, sugar-sweetened beverages, fruit juices, and desserts or sweets; and animal foods such as meat, animal fats, eggs, dairy, seafood or fish, and other animal-based foods.

The distinction between healthy and unhealthy plant foods was based on their association with type 2 diabetes, certain cancers, cardiovascular disease, and other disorders, such as obesity and hypertension.

Blood samples were tested to create metabolite profile scores for the individuals, and any cases of incident type 2 diabetes throughout the follow-up period of the study were noted. Analyses of these data along with the diet index scores made it possible for the reserachers to find any connections between diet index, metabolite profile, and risk of type 2 diabetes.

They found that in comparison to individuals who didn’t develop type 2 diabetes, those who were diagnosed with the disorder throughout follow-up had a reduced intake of healthy plant-based foods, and also reduced scores for Plant-based Diet Index and healthy Plant-based Diet Index. They also had a higher BMI on average and were more likely to have a family history of diabetes, high cholesterol levels, and hypertension, use cholesterol and blood pressure medications, and be more physically inactive.

The metabolomics data showed plant-based diets to be linked to specific multi-metabolite profile patterns, with significant differences between the unhealthy and healthy plant-based diets.

Metabolite profile scores for the general plant-based diet, as well as the healthy plant-based diet, were also inversely linked to type 2 diabetes in generally healthy individuals, independent of BMI and other risk factors for diabetes, while no connection was seen for the unhealthy plant-based diet.

Higher metabolite profile scores for Plant-based Diet Index and healthy Plant-based Diet Index subsequently indicated stricter adherence to those diets as well as having a reduced type 2 diabetes risk.

After adjustments were made for levels of isoleucine, hippurate, trigonelline, a small set of triacyglycerols, and a number of other intermediate metabolites, the connection between plant-based diets and type 2 diabetes mostly disappeared, indicating that they could play a significant part in associating those diets with incident diabetes.
