a recent study published in the journal Nutrition and Dietary Sciences, the Dietary Guidelines for Americans recommend reducing the intake of certain foods, including fortified grains, which can have unintended public health effects on children. The
22
-page study investigates and strongly supports the value of fortified and rich foods in the U.S. diet, as well as the dominance of cereals in the U.S. diet as a major source of minerals.researchers note that in addition to the nutritional contribution of
, fortified foods are rarely used as a target food to increase intake, and are sometimes recommended to reduce intake of refined cereals and fruit juice drinks.

Foods that provide trace element sources overlap se partially with foods that reduce the source of the target ingredient intake, so be careful not to influence the intake of important trace elements when following dietary recommendations, such as limiting intake of macronutrients from certain foods,

”The study was conducted by a team led by

professor in the Department of Food Science and Nutrition at California State University in San
Luis Obispo, California. Other researchers are from the Friedman School of Medicine, the School of Nutritional Sciences and Policy at Tusf University in Boston, the Dietary Supplements Institute at the National Institutes of Health in Bethesda, Maryland, and the Food and Nutrition Database Research Corporation.researchers are trying to figure out the effects of fortifications on nutritional enhancement in U.S. teens and children, and rank foods that increase nutritional intake. The study also looked at excessive intake of certain nutrients caused by fortification.studies have shown that non-enhanced nutrition can lead to inadequate intake of multiple trace elements in many children and adolescents, especially adolescent girls.

” On the other hand, the researchers found that although nutritional enhancers can eliminate diseases caused by undernourishment, such as rickets and brown skin diseases, the enhancers are still rated as dangerous. This review is due to

that the fortification may cause excessive nutrient intake.
” Zinc was found to be an example of excessive nutrient intake, according to guidelines established by the Institute of Medicine. Limited

for children and adolescents, the

and calcium. However, increasing the intake of the target population without the potential harm of excessive harm to others will also be a continuing challenge. in addition to the study, reducing the intake of refined cereal products, such as bread, ready-to-eat grains and pasta, may lead to inadequate micronutrient intake, and the researchers note that reducing drinks and a grain-based diet can also have side effects.

” The Dietary Guidelines Advisory Committee has proposed replacing dietary patterns with whole grains (rough grains) for fortified cereals. The pattern assumes that consumption of whole grains, fruits, and vegetables is difficult to achieve in real life. Even in accordance with the Committee's recommended model, there is still a degree of nutritional deficiency. "
model shows that replacing refined grains with whole grains instead of nutritionally enhanced whole grain products such as ready-to-eat grains can lead to folic acid and iron deficiencies, and reduce (but still adequate) thiamine, niphosphonate, and nucleophotin levels

researchers noted, noting that
"
these carefully considered options, such as recommended fruit and vegetable intake, are consistent with dietary guidelines. From a public health perspective, changes in fortified food intake and any changes in synthetic nutrient intake should be proposed. In addition, modifying the
/
strategy can help optimize dietary guidance based on food and nutrient intake. authors say the results are strong evidence of food fortification.

if nutrients are not added, a large proportion of children and adolescents will lack multiple micronutrients, and older girls will suffer from severe deficiencies.

through nutritional fortification, reducing the proportion of people who eat less than the average recommended intake, and does not lead to excessive intake of trace elements. The data show the strong impact of nutrition-enhancing policies on food resource rankings.
