Wheat
and corn are natural plant foods that offer an abundance of nutritional value.
You can find several varieties of both wheat and corn. Wheat typically
undergoes an elaborate milling process in which much of the nutritional value
is eliminated, while corn can vary in nutritional value based on species and
size. For comparison, nutritional data is presented based on the common forms
of durum wheat and sweet yellow corn, and serving sizes are based on nutrient
content per 100 g.
Energy Value
The
energy value of a particular food can be measured by its caloric content.
Calories are a measure of heat and provide an indication of how much energy
that food provides the body to fuel its metabolic and physical activities.
Wheat has a much higher energy density, with 339 calories per 100 g versus the
86 calories per 100 g of corn. The majority of the weight in corn exists as
water.
Carbohydrates
Both
wheat and corn gain most of their caloric value from their carbohydrate
content. Wheat, however, contains about 71 g of carbohydrates per 100 g, while
corn contains just less than 19 g. Most adults require about 225 to 325 g of
carbohydrates each day to support their energy needs.
Protein
Wheat
is a significant source of protein with about 14 g per 100 g. Corn, on the
other hand, contains 3.27 g of this macronutrient. Protein plays a central role
in growth and tissue repair, and most adults require about 50 to 175 g of
protein each day to meet their nutritional needs.
Fat
Wheat
contains about 2.5 g of fat per 100 g, while corn contains 1.35 g. Both wheat
and corn are substantially higher in healthy unsaturated fats than saturated,
and are each free of cholesterol. Most adults need about 44 to 78 g of fat each
day, and the majority of your fat intake should come from unsaturated fats such
as those found in wheat and corn. Both wheat and corn contain polyunsaturated
fats, which can help reduce blood cholesterol and have a positive effect on the
cardiovascular system.
Minerals
Wheat
is generally higher in minerals than corn and offers higher amounts of iron,
magnesium, phosphorous, potassium, zinc, copper, manganese and selenium. Corn's
most significant mineral contribution, based on recommended adequate intake
values set by the Food and Nutrition Board of the Institute of Medicine, is its
potassium content. Corn contains just trace amounts of other minerals.
Vitamins
Corn
offers a wider array of vitamins than wheat, with moderate-to-high amounts of
vitamin C and B-vitamins and small amounts of vitamins A, E and K. Wheat is
high in most of the B-vitamin complex but does not contain any other vitamins,
according to the USDA database.
