The Healthy Cantonese Diet on Cardiometabolic Syndrome
19 de agosto de 2019 actualizado por: Huilian Zhu, Sun Yat-sen University
Effect of the Healthy Cantonese Diet on Cardiometabolic Syndrome in Chinese Adults
The DASH diet (Dietary Approaches to Stop Hypertension) have been proven to lower risk of cardiovascular diseases.
But the DASH diet is inconsistent with Chinese dietary pattern.
In this study, based on the typical Cantonese diet, the healthy Cantonese diet is developed according to the DASH diet and the balanced dietary pattern of the Chinese Dietary Guidelines 2016.
The randomized control trial is designed to investigate whether the healthy Cantonese diet has benefit to blood pressure, blood lipid, blood glucose and other cardiometabolic biomarkers among adults with cardiometabolic syndrome in Guangdong, China.

Experimental: the healthy Cantonese diet
Based on the typical Cantonese diet, the healthy Cantonese diet is developed according to the DASH diet and the balanced dietary pattern of the Chinese Dietary Guidelines 2016.
In this diet, the main nutrients, dietary fiber, sodium, calcium, magnesium and potassium are set to achieve the healthy goal.
Compared with the typical Cantonese diet, the healthy Cantonese diet is increased in fruit, vegetables, low-fat dairy products, whole grains, nuts and seeds, and reduced in salt, oil and sweets.
|
After a 1-week run-in period, the intervention group will eat the healthy Cantonese diet for 4 consecutive weeks.
Free meals will be provided 3 times a day (breakfast, lunch, dinner).
The actually intake of every meal for all subjects will be recorded to estimate their nutrients intake.
All subjects will be advised to avoid eating other food, but they should inform researchers of what they eat if they eat food that we will not provide.

Comparador de placebos: the typical Cantonese diet
The typical Cantonese diet is a diet of what many Cantonese eat.
In this diet, the main nutrients, dietary fiber, sodium, calcium, magnesium and potassium are set at the average dietary intake levels in Guangdong.
|
After a 1-week run-in period, the control group will still eat the typical Cantonese diet for 4 consecutive weeks.
Free meals will be provided 3 times a day (breakfast, lunch, dinner).
The actually intake of every meal for all subjects will be recorded to estimate their nutrients intake.
All subjects will be advised to avoid eating other food, but they should inform researchers of what they eat if they eat food that we will not provide.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|

Periodo de tiempo: before and after 4-week intervention
|
Changes of metabolic syndrome score in healthy Cantonese diet compared with changes of typical Cantonese diet.
Metabolic syndrome score will be derived by standardizing and then summing the following continuously distributed indices of adiposity (waist circumference) to create a z score: hypertension (the average of systolic blood pressure and diastolic blood pressure); hyperglycaemia (fasting plasma glucose); insulin resistance (fasting insulin); fasting HDL-cholesterol × -1; and fasting triacylglycerol z score.
