TL;DR: Strategies to improve dietary intake among SNAP recipients should consider both increasing home cooking and reducing fast food intake, including lower sugar-sweetened beverage intake and reduced prevalence of overweight/obesity.

TL;DR: Because of the proliferation of food quacks in recent years and the danger they represent to the general public, physicians need to make preventive health care an important part of their responsibility.
Abstract: Foods rich in vitamins, especially those containing beta carotene and vitamin C, lower the risk of cancer in humans. Whether vitamins alone are responsible for this reduced risk is not known. They may work synergistically with increased dietary fiber and decreased fat intake. Vitamin supplementation at doses higher than the recommended daily allowance is, at present, an unknown factor in preventing cancer and may cause toxic effects in some instances. Consuming megadoses doses of any vitamin or mineral as a cancer preventive should be discouraged. Physicians need to take a more aggressive stance against alternative health care providers who recommend questionable dietary or nutritional regimens. Because of the proliferation of food quacks in recent years and the danger they represent to the general public, physicians need to make preventive health care an important part of their responsibility. This includes educating patients on proper nutrition.

TL;DR: Evidence of growth retardation and wasting in this population, coexisting with emergent obesity, is revealed, and the development of a nutrition and health policy to address the problems of both deficit and excess represents a pressing challenge.
Abstract: During the first quarter of 1990 Xhosa-speaking nurses interviewed mothers and took anthropometric measurements of 163 children 3-6 years old living in squatter and formal housing areas of Cape Town South Africa to determine the nutritional status of the children. 39% of the children received less than 67% of the recommended daily allowance (RDA) of calories (i.e. deficiency) and 3% received more than 120% of the RDA. Most children were deficient in calcium (80%) iron (77%) vitamin A (64%) riboflavin (52%) niacin (53%) vitamin B6 (58%) and vitamin C (76%). Most children received more than 120% of the RDA for folic acid (68%) and for vitamin B12 (63%). Milk consumption was low (median intake 0.5 portion vs. 2-3 portions as recommended by the department of national health and population development guidelines). The diet was also deficient in vegetables and fruit intake (1.32 vs. =or> 4 portions) and fat intake (2.5 vs. =or> 4 portions). Children did receive adequate portions of meat and foods from the cereal group however. Macronutrient energy distribution fell within prudent dietary guidelines: 28.1% of energy from total fat 63.7% from carbohydrates and 13.2% from protein. 44.8% of children had only 2 meals with more than 600 kJ. 15 children (9.2%) had only 1 meal. 27.6% were stunted. 7.7% were underweight. 7.9% were wasted. 20.1% were obese. The undernourished children and the obese children consumed a diet low in micronutrients. These anthropometric findings indicate a population in transition--acutely and chronically undernourished children coexisting with obesity. The overall findings suggest a need to develop a nutrition and health policy to address nutrient deficit and excess.

TL;DR: Severe deficiency in vitamin intake among women and rural dwellers may partly explain the high incidence of EC among inhabitants in rural areas and the male:female ratio that is approximately 1 in Golestan; while EC is much more common in men in many low-incidence areas.
Abstract: Objectives: Dietary factors seem to play a major role in esophageal carcinogenesis in Golestan Province, a high-incidence area for esophageal cancer in northern Iran. The current study was conducted to evaluate previous reports on severe de�ciency of vitamin intake in Golestan. Methods: Using a food frequency questionnaire, food intake data were collected from 30,463 healthy participants in the Golestan Cohort Study. Intake of selected nutrients was compared with recommended daily allowance and lowest threshold intake values. Results: Vitamin A intake in the majority of participants was lower than recommended values. The proportion of participants with intakes lower than lowest threshold intake was as follows: urban men, 20%; urban women, 31%; rural men, 48%;

TL;DR: The results showed the need for improvement in dietary choices to minimize the prevalence of inadequate intake of folate, zinc, copper, and calcium in this group of female university students.
Abstract: The objective of this study was to estimate the prevalence of inadequate usual nutrient intake among female university students. This was a cross-sectional study in which 119 students at a public university in the State of Sao Paulo, Brazil, completed 3-day estimated food records. These were analyzed for nutrient content, and intake distributions were determined. Nutrient intake distributions were estimated using the National Research Council method. For nutrients for which an Estimated Average Requirement has been established, the Estimated Average Requirement cutpoint method was used to determine the proportion of students with inadequate intake. The students' food records indicated inadequate intakes of folate (99%), zinc (47%), and copper (33%). For approximately 95% of the students in this study, calcium was less than the Adequate Intake. The results showed the need for improvement in dietary choices to minimize the prevalence of inadequate intake of folate, zinc, copper, and calcium in this group.
