Nutrition experts say rootcrops, corn help prevent various diseases

Ever wonder what rootcrops and corn can do to our body?

Rootcrops and corn are good sources of carbohydrates which can be included in the
diet to meet the energy and nutrient requirements of the body.

Rootcrops also contain dietary fiber, vitamin C, calcium, phosphorus and iron.
Examples of rootcrops locally available are sweet potatoes, purple yam, taro,
cassava and potatoes.

Corn, on the other hand, is also a good source of of corn are white and yellow.
A study conducted by the Food and Nutrition dietary fiber, B-vitamins, ascorbic
acid, folate and phosphorus. Popular varieties Research Institute of the Department
of Science and Technology (FNRI-DOST) determined the effects of local root crops
in lowering cholesterol levels among humans with moderately-raised cholesterol
levels.

The study showed that eating kamote and cassava significantly decreased the total
cholesterol levels of adults. Specifically, cassava was shown to have significantly
decreased LDL-cholesterol levels.

The study concluded that rootcrops, due to their dietary fiber content, could have a
significant role in the reduction of lipid biomarkers.

Another study by the FNRI-DOST explained that dietary fiber that is fermented in
the large intestine (or colon) binds with toxins and is excreted in the feces. Toxins
in the colon contribute to the formation of tumors and cancer.

Folate present in corn is good for the heart because it lowers the level of
homocysteine, an amino acid responsible for damaging the blood vessels and
increasing the blood clotting, which may lead to heart attack.

Corn also contains carotenoid beta-cryptoxanthin, which aids in lowering the
chances of lung cancer.

Other health benefits from corn include the increase in memory levels due to
thiamin which is important in brain cell functions., and together with panthothenic
acid, helps in energy production and stress reduction.

Glycemic index is the individual’s glucose response to a food as compared to a
reference food and tells whether and how a food will raise blood sugar levels.

Rootcrops and the white variety of corn have low glycemic index at less than 60,
which means that they are beneficial in the proper control and management of
diabetes mellitus and in maintaining normal weight.

Message 5 of the Nutritional Guidelines for Filipinos (NGF), developed by a technical
working group (TWG) headed by the FNRI-DOST, states that one should eat more
vegetables, fruits, and root crops. In the Daily Nutritional Guide for lactating
women, it is suggested that they consume 6-7 servings of rice, corn, rootcrops, and
their substitutes.

Root crops and corn have a lot of nutritional and health benefits, so why not include
them in your daily diet?

Recipes with root crops and corn are featured in the 2011 FNRI Menu Guide
Calendar.

The calendar includes 12 monthly-7 day cycle menu, estimated energy and nutrient
contribution per recipe, information about root crops and corn, and nutrition and
