The gut’s immune system is ultimately responsible for maintaining a healthy gut free of infection or infestation. It must accomplish this task while at the same time being unresponsive to food and helpful bacteria (1). Gastrointestinal inflammation etiology is largely infection such as via parasite. However, modern lifestyles have increasingly been harassed by new chronic inflammatory diseases such as Crohn’s or ulcerative colitis (1). These are associated mainly with genetic mutations or adaptive immunity affecting immune system recognition as well as by epithelial permeability (1). Stool tests indicating gastrointestinal inflammation include those for fecal proteins such as eosinophil protein-X (EPX), fecal calprotectin (FC) and fecal myeloperoxidase (MPO): FC is a calcium-binding protein found in large amounts in neutrophils and macrophages, which rush into the lumen at onset of inflammation (2-4). FC is considered more sensitive than endoscopy, for example, for evaluating inflammat...

Nutritional and energy needs for a child differs profoundly from that of an adult because of a child's continual growth and development. A child is in greater need of nutrient-dense foods--although not to the extent as infants--and requires more energy for basal metabolic rate, physical activity and thermic effect of food. Energy needs are highest during rapid growth and expansion of lean mass. Each individual child is best understood by first dividing stages of child growth and development into two periods: a preschool period and a school-age period: During the pre-school period, from 2-6 years of age, the child grows more slowly in comparison to infancy. A toddler will quadruple birth weight in a full year or so. The brain of the toddler also grows more slowly than as was expected as an infant so head circumference will only increase by a couple of centimeters. A toddler's weight increase can range from 2.5 kg per year for ages 2 and 3 to 2 kg per year for ages 4 and 5. She o...

Protein status is assessed by evaluating both somatic and visceral protein status. Somatic protein status is a measure of the protein in skeletal muscle while visceral protein status is a measure of all other proteins (organs, viscera, serum, blood cells, white blood cells). Evaluation of somatic protein status can generally be performed using muscle circumference or mid-arm muscle area. However, because no single indicator is completely accurate biochemical measures can help better provide perspective for somatic protein status. Creatinine serves as a useful measure because creatinine is produced in the skeletal muscle. The more skeletal muscle a person has, the more creatinine will be excreted. A 24-hour urinary creatinine excretion test is easily tested in the laboratory. The measure can then be compared to standards based on stature and body weight. The 24-hour urinary creatinine excretion can also be compared to reference values from the creatinine-height index (CHI). The CHI is a...

The infant, despite whether healthy term or high-risk, will require energy for BMR, thermic effect of food, physical activity, maintenance, growth and for energy lost in feces and urine. There is also energy needed just to maintain body temperature until the early extrauterine period passes. The newborn requires approximately 108 kcal/kg for about six months followed by 98 kcal/kg for the next six. The high-risk newborn will have the same energy requirements, but Calorie needs will differ in whether or not the infant is enterally fed or parenterally fed. The enterally fed infant needs a greater amount of Calories, at 120/kg, than the healthy infant due to specific dynamic action and cold stress. The parentally fed will need fewer amount of Calories, at about 80-90 kcal/kg, than the healthy infant because of the infant won't use as many calories for activity, cold stress, specific dynamic action or stool losses. Caloric needs for both enterally and parenterally fed high-risk infants...

One interesting detail I came across while researching teratogens is that a protein-deficient diet may enhance the effects of xenobiotics in general. For example, dietary protein deficiency along with exposure to inorganic arsenic through injection in mice was found to increase risk of birth defects, possibly because of lack of methyl donors for arsenic methylation (1). Also, high-dose caffeine teratogenicity is increased when in combination with protein deficiency (2). Other xenobiotics such as tobacco carcinogens, anticonvulsants and sedatives appear to be teratogenic depending on the status of the cytochrome P450 system of the fetus (1). The effect may or may not be related to protein deficiency. The toxicity is thought to occur due to lack of anitoxidative enzymes such as GSH peroxidase and GSH reductase, which would increased endogenous oxidative stress and cumulative damage (3).

I was shocked to learn that FDA in 1980 had determined that caffeine in amounts exceeding 300 mg could potentially be teratogenic (1). Teratogens are agents that cause fetal malformations or birth defects. Good thing caffeine does not harm the fetus when taken in smaller amounts, despite evidence in rats to the contrary (1-2). However, after digging deeper, I found that the researchers did find that caffeine potentiated teratogenic effect of smoking and alcohol (2). The mechanism appears to be through inducing materno-fetal vasoconstrictions that lead to ischemia (2). If caffeine potentiates effects of other teratogens in amounts less than 300 mg, I imagine it's still wise of pregnant women to avoid caffeine altogether during pregnancy just in case they are exposed to teratogens of some kind and are unaware of it.

Cannabis sativa’s psychoactive tetrahydrocannabinol (THC) has not been established as a human teratogen (1), but there is a history of teratogenic effects linked to use by expectant mothers (2). The perinatal exposure is thought to interfere with neurodevelopment and affect neurobehavorial outcomes (1-2). Although the teratogenicity of marijuana is not as catastrophic as other illicit drugs such as cocaine, it’s harm can still lead to problems such as disturbed sleep and attention deficit disorder (2-3). Worth noting is that when cocaine exposure is accompanied by marijuana, the neurological effects can be pronounced (3). There is also indication that maternal marijuana use may increase risk of acute myeloid leukemia, however, more recent research has not been able to confirm this relationship (4). Reference List 1.

Nutritional needs soar when you have a multiple pregnancy. According to Barbara Luke from University of Miami, the mother has a “greater nutritional drain” on her body. Because of quicker glycogen depletion that might slow fetal growth rate, Luke suggests a diabetic regimen with caloric ratio of 40% carbs, 20% protein, and 40% fat. In addition, she suggests supplementation with iron, calcium, magnesium and selenium for preventing “complications and improvement of postnatal health”. Reference List Luke B.

Eggs, considered a nutritional powerhouse, is an excellent food to recommend to these women during pregnancy. According to Niva Shapira of Tel-Aviv University in Israel, eggs can provide various nutrients, vitamins and minerals that are also found in human milk and that support peak brain development (1). If those eggs are also produced in such a way as to contain high levels of DHA, then they become even more supportive to the young one’s brain (2). Reference List 1. Shapira N. Modified egg as a nutritional supplement during peak brain development: a new target for fortification. Nutr Health 2009;20:107-18. 2. Carlson SE.

On July 17, 2008, a study was published (1) that I believe should change how nutritionists and dietitians would look at the current Dietary Guide for Americans, the Food Guide Pyramid and the whole concept of a “heart-healthy” low-fat diet as recommended by the American Heart Association. The paradigm-shift study was a 2-year intervention trial in The New England Journal of Medicine in which weight loss was compared among moderately obese subjects who were assigned to either a restricted-calorie Mediterranean diet, a non-restricted calorie low-carbohydrate, or a typical restricted-calorie low-fat diet (1). What did they find? Surprising results. All the subjects lost weight, but were greater in both the low-carbohydrate group (despite nonrestricted calories) and the Mediterranean-diet group (1). The lipid profiles, more surprisingly, improved in the Mediterranean-diet group and most in the low-carbohydrate group (1). Best LDL cholesterol levels were found among the Mediterranean-diet g...
