North American Indians have a higher morbidity from gallbladder disease, diabetes mellitus and obesity than other North Americans; this may result from their food intake. Nutrient intake and meal patterns were compared in 120 Micmac Indian and 115 Caucasian women in Shubenacadie, NS. Findings were compared with the Canadian Dietary Standard (CDS) and the Nutrition Canada national and Indian survey reports. The diet of Indian women had higher carbohydrate, lower protein and lower fibre content than that of Caucasian women, who derived a higher percentage of energy from protein and had a higher intake of vitamin A, niacin and ascorbic acid. Overnight fast was longer among Indian women. A high percentage of all women studied reported diets that did not reach the CDS for total energy intake in kilocalories or for calcium, iron, vitamin A, thiamin or riboflavin.
北美印第安人患胆囊疾病、糖尿病和肥胖症的发病率高于其他北美人；这可能是由他们的食物摄入量导致的。在新斯科舍省舒贝纳卡迪的120名米克马克印第安妇女和115名白人妇女中比较了营养摄入量和饮食模式。研究结果与加拿大饮食标准（CDS）以及加拿大营养协会的全国和印第安调查报告进行了比较。印第安妇女的饮食中碳水化合物含量较高，蛋白质和纤维含量较低，而白人妇女从蛋白质中获取的能量比例更高，维生素A、烟酸和抗坏血酸的摄入量也更高。印第安妇女的夜间禁食时间更长。在所有接受研究的妇女中，很大一部分人报告说，她们的饮食在千卡总能量摄入量或钙、铁、维生素A、硫胺素或核黄素方面未达到加拿大饮食标准。
