Chapter 15 (part2)Food Facts and Fallacies
Pastor,Rydni B.
Dairy productsCow’s milk
Fallacy: any milk other than cow’s milk is desirable. Goat’s milk is nutritious and is recommended
Fact: goats are not susceptible to tuberculosis. Pasteurization makes the cow’s milk safe by killing the tuberculosis germ.
Dairy productsYogurt-is fermented whole milk eveporated to
2/3 of its original volumeFallacy:yogurt is nutritionally superior to milkFact: yogurt has the same nutritive value as
whole milk. It provides a source of milk in other forms
Dairy productsMilk and cheese
Fallacy: these are constipatingFact: milk and cheese are easily digested and
leave a little residue. (constipation may occur when the diet lacks food that contain bulk)
Dairy productsPasteurized milk
Fallacy: it is “dead milk”Fact: pasteurization does not alter the
nutritional value of milk except to reduce the Vitamin C content slightly.(milk is a poor source of Vitamin C) Pasteurization destroys bacteria that can cause
undulant fever and tuberculosis
Bread and Cereal ProductsFallacy: Gluten,protein bread and dark bread
are less fattening than white breadFact: breads vary little in caloric ocntent.
Thus one bread is not superior to another in the standpoint of weight loss
Bread and Cereal ProductsFallacy: white bread and white flour are unfit
for human consumption because all of the vitamins and minerals have been removed and the bleaching process is poisonous
Fact: almost all commercial white breads and white flours are restored and enriched (according to law) with niacin, iron, thiamine and riboflavin. Chlorine Dioxide is a harmless compound that
is used to bleach flour.
Meat, Fish, and EggsFallacy: eggs with brown shells are more
nutritive than white shell eggsFact: the color of the shell is determined by
the breed of the hen and it does not indicate the nutritive value of the egg
Meat, Fish, and EggsFallacy:the characteristics of the type of meat
are transmitted by consumptionFact: this is not true
Meat, Fish, and EggsFallacy: meat that is raw or cooked rare is
more nourishing than well-done meatFact: proteins are not damaged by cooking.
Cooking protects the individual from bacterial infections and disease e.g. trichinosis
Meat, Fish, and EggsFallacy: fish is brain foodFact: The brain contains phosphorus and fish
is a rich source of this mineral. The reasoning is invalid.
VegetablesFallacy: drink your vegetablesFact: vegetable juice make excellent
contribution to the diet but do not contain the bulk necessary to the diet
VegetablesFallacy:
Tomatoes clear the brainOnions will cure the coldLettuce is soothing to the nerves
Fact: there is no scientific evidence to substantiate his claims
SugarsFallacy: blackstrap molasses cures practically
every affliction,from restoring color to gray hair to restoring youth
Fact: it contains small amounts of calcium(from the limewater used in processing), iron(comes from the contact with the factory machinery) and B complex vitamins
CondimentsFallacy:spices and condiments have the
power to prevent diseaseFact: the belief that diseases originated in
foul-smelling air may have led to the conclusion that pungent smell can ward of disease
CondimentsFallacy:spicy foods have the reputation for
being cooling and for that reason are eaten in tropical countries
Fact: hot weather and a natural increase in water intake cause appetites to lag. Spices tend to stimulate a desire for food.
WaterFallacy: drinking water with meals dilute the
gastric juice and interfere with digestionFact:water stimulates the flow of digestive
juice
WaterFallacy: large amounts of water are said to
thin the bloodFact: there is no evidence for this
WaterFallacy: drinking water will increase weightFact: water drunk in excess of body needs to
be eliminated
LecithinFallacy: Lecithin removes fat depositsFact: There is no good evidence to indicate
that lecithin lowers serum cholesterol levels or that it has a role in the treatment of coronary heart disease
Megavitamin TherapyUse of megadoses of vitamins for
improvement of health is based on the concept that if a little is good,more must be better(which is not true)
Use of megadoses of vitamins for conditions other than acute vitamin deficiency is not scientifically sound
Excessive doses of vitamins may have pharmaceutical or toxic effect or both
Megavitamin TherapyOnly two groups of disorders are corrected or
alleviated by large doses of specific vitamins:Malabsorption syndromeSome inborn errors of metabolism
Megavitamin TherapyJustifications for megadoses of vitamins:
Providing optimal healthIndividual variabilitye.g.pregnant women*large doses of Vitamins A and D,which can be
stored are actually toxic when they accumulate
Megavitamin TherapyMegadoses of Vitamin C
There is no evidence that Vitamin C can kill cold-carrying virus.There is some preliminary evidence that Vitamin C may have antihistamic effects(some people will have reduced symptoms if they take vitamin C)
Can cause: acidic urine with accompanying burning sensations on
urination Inaccurate glucose tests in diabetes Can cause kidney problems(overproduction of oxalate can
result in formation of oxalate stones)*RDD=60 mg for an adult
Megavitamin TherapyMegadoses of Vitamin E
Vitamin E acts as an antioxidantvitamin E excess can induce the development
of ‘flu-like’ symptoms and may be toxic to some extent
Can cause an Interference with vitamin K activity(prolongation of coagulation time)
Vegetarianism
Vegetariana person whose diet is composed
predominantly of plant foodAbstains from the consumption of meat, fowl or
fish but may eat eggs and dairy products
Different types of vegetarians include: Pure vegetarian (vegan)- consumes only plant foods Lactovegetarian-eats dairy products as well as plant
foods Fruitarian-whose diet consists chiefly of fruits
Motives: Health concerns Religious or philosophical belifs both
Risks of a Vegetarian DietCaloric needs are difficult to meet (particularly in
children)because the diet is high in bulk.Diminished caloric intake would require increased
bodily use of protein (which may not be abundant in the diet) as an energy source
There may be low calcium,vitamin D and riboflavin intake especially for children.(a lactovegetarian diet is safe for children)
Zinc and vitamin B12 deficiency may develop because the best sources of both are animal products
May cause iron deficiency to infants, children, and pregnant women (those who have a great need for iron)
Benefits from a Vegetarian DietLess likelihood of atonic constipationLower incidence of artherosclerosisReduced blood pressureLower death rates from cancers of breast,
intestines, lungs, and mouthLow blood levels of cholesterol and
triglycerides
Health risks can be a voided when dietary planning is based on:Milk groupProtein groupFruit and vegetable groupBread and cereal group*If more calories are necessary,the fifth group
may be used prudently with the approal of your physician
Fats,sugars and alcohol
