Abstract
Refined
carbohydrates, such as white rice and white flour, are the mainstay of
the modern Asian Indian diet, and may contribute to the rising incidence
of type 2 diabetes and cardiovascular disease in this population. Prior
to the 1950s, whole grains such as amaranth, barley, brown rice,
millet, and sorghum were more commonly used in Asian Indian cooking.
These grains and other non-Indian grains such as couscous, quinoa, and
spelt are nutritionally advantageous and may be culturally acceptable
carbohydrate substitutes for Asian Indians. This review focuses on
practical recommendations for culturally sensitive carbohydrate
modification in a modern Asian Indian diet, in an effort to reduce type 2
diabetes and cardiovascular disease in this population.

INTRODUCTION
Asian
Indians and Asian Indian immigrants to the United States (U.S.) face a
distinct transition in nutrition and dietary practices. Immigration is
generally associated with higher caloric intake1 and higher intake of refined and processed grains2; less physical activity3; and consequent weight gain.1
Nutrition counseling should initially target reduction in caloric
excess, reduction of refined, processed grains and added sugars, and
include other interventions to promote weight loss and reduce disease
burden.
Despite normal weight, Asian Indians are at higher risk for type 2 diabetes and other metabolic abnormalities. 4–11
The modern Asian Indian diet is particularly high in refined
carbohydrates and low in protein, when compared to other dietary
traditions.12–13
Recent studies in India have established strong positive associations
between refined grain intake and type 2 diabetes, and confirm the
protective effect of fiber, which is contained in whole grains.14 Observational studies have shown that whole grains15–18
are associated with weight loss, reduced insulin resistance and type 2
diabetes. Carbohydrates are integral to Asian Indian dietary traditions,19
and re-introduction of culturally acceptable, traditional,
carbohydrate-rich grains with high nutrient density may be a prudent
step in reducing disease burden in this population.
Since
the 1951 Green Revolution in India, refined grains such as white rice
and refined wheat flour have become staples of the modern Asian Indian
diet.19
The Green Revolution was an attempt by the Indian government to avoid
reliance on foreign food aid (following independence from British
imperialism) by developing and subsidizing inexpensive, high-yield
crops.19 Prior to this nutrition transition in India, traditional meals and recipes were derived from whole grain carbohydrates14
and included amaranth, barley, millet and other ancient grains that
have been grown on the Indian subcontinent for the past few millennia.
This
paper seeks to review and provide recommendations on employing various
ancient, whole grains as a preferred carbohydrate source in a modern
Asian Indian diet—particularly an immigrant diet—to achieve a balance of
macronutrients, micronutrients, fibers, and phytochemicals for optimal
health promotion and in order to prevent chronic diseases such as type 2
diabetes, cardiovascular disease (CVD), and obesity. Use of these
grains may also allow individuals to make healthful dietary changes that
align with cultural tradition, because Asian Indians place particularly
high value on traditional diets and may feel more comfortable modifying
their traditional diets rather than adopting a new, more Western diet
altogether.20
Providing more healthful and traditional whole grain substitutes for
refined carbohydrates can be thought of as one important aspect of
therapeutic dietary modification. Asian Indian immigrants in the United
States and their healthcare providers can collaboratively use this
information to achieve better health outcomes. These recommendations can
also be extrapolated and tailored to other Asian Indian diaspora
populations around the world; similar approaches to culturally sensitive
recommendations for lifestyle and diet modification may be appropriate
in other racial/ethnic groups in different regions of the world as well.
