LE LAIT
Nutriments les plus importants
Calcium. Le lait est une excellente source de calcium. Ce minéral est de loin le plus abondant dans le corps. Le calcium est majoritairement entreposé dans les os, dont il fait partie intégrante. Il contribue à la formation des os et des dents, ainsi qu’au maintien de leur santé. Le calcium joue aussi un rôle essentiel dans la coagulation du sang, le maintien de la pression sanguine et la contraction des muscles, dont le coeur. Phosphore. Le lait est une excellente source de phosphore (voir notre fiche Palmarès des nutriments Phosphore). Le phosphore est le deuxième minéral le plus abondant de l’organisme après le calcium. Ce minéral joue un rôle essentiel dans la formation et le maintien de la santé des os et des dents. De plus, il participe entre autres à la croissance et à la régénérescence des tissus, aide à maintenir le pH du sang à la normale et est l’un des constituants des membranes cellulaires. Vitamine B2. Le lait est une excellente source de vitamine B2, vitamine connue aussi sous le nom de riboflavine. Tout comme la vitamine B1, elle joue un rôle dans le métabolisme de l’énergie de toutes les cellules. De plus, elle contribue à la croissance et à la réparation des tissus, à la production d’hormones et à la formation des globules rouges. Vitamine B12. Le lait est une excellente source de vitamine B12. Cette vitamine travaille de concert avec l’acide folique (vitamine B9) pour la fabrication des globules rouges dans le sang. Elle participe aussi à l’entretien des cellules nerveuses et des cellules fabriquant le tissu osseux. Vitamine D. Le lait constitue une excellente source de vitamine D. La vitamine D est étroitement liée à la santé des os et des dents, en rendant disponibles le calcium et le phosphore dans le sang, entre autres pour la croissance de la structure osseuse. La vitamine D joue aussi un rôle dans la croissance des cellules, dont les cellules du système immunitaire. À noter que la vitamine D est ajoutée au lait.
Sélénium. Les laits 1 % et 3,25 % sont de bonnes sources de sélénium, tandis que les laits écrémé et 2 % n’en sont que des sources. Ce minéral travaille avec l’un des principaux enzymes antioxydants, prévenant ainsi la formation de radicaux libres dans l’organisme. Il contribue aussi à convertir les hormones thyroïdiennes en leur forme active. Acide pantothénique. (Vitamine B5). Le lait est une bonne source d’acide pantothénique. Il fait partie d’un coenzyme clé dans l’utilisation de l’énergie des aliments que nous consommons. Il participe aussi à plusieurs étapes de la synthèse des hormones stéroïdiennes, des neurotransmetteurs et de l’hémoglobine. Vitamine A. Les laits écrémé, 1 % et 2 % sont de bonnes sources de vitamine A, tandis que le lait 3,25 % en est seulement une source. La vitamine A est l’une des vitamines les plus polyvalentes, jouant un rôle dans plusieurs fonctions de l’organisme. Cette vitamine favorise entre autres la croissance des os et des dents. Elle maintient la peau en santé et protège contre les infections. De plus, elle joue un rôle antioxydant et favorise une bonne vision, particulièrement dans l’obscurité.
Milk myth busted: There are far better sources of calcium for strong bones
by Madeleine Innocent
(NaturalNews) As the truth is beginning to tumble out about diet and health care, the milk myth is deserving of a closer look. The world at large has been brainwashed into thinking that milk and dairy are the ultimate (and only) source of calcium, not just for growing children. However, not only is dairy indigestible to many, it is also a source of disease.
Milk is For Babies
Mother’s milk is the ultimate source of food for a growing baby. However, not only is that particular mother’s milk unique, and so best suited, for that particular baby, her species produces the most suitable milk for her baby.
Species differ widely. For example, cows reach physical maturity in a single year. Humans take in the order of sixteen years to reach physical maturity. This means the components of the milk must be different to suit the needs of the species. For example, the calcium/protein ratio varies with each species.
Once a baby is weaned, their stomach environment changes. Mother’s milk is an easy food to digest. Now, more complicated foods are being eaten, so these must be catered for. The need to digest milk, and so the process, tapers off. Now milk becomes indigestible. Lactose intolerance is rife, showing this to be so.
The Best Source of Calcium
Babies grow very quickly. This leads to the assumption that milk is responsible. However, when you consider that a cow, or any large herbivore, reaches physical maturity about sixteen times faster than a human, with bones which are three to four times bigger, then one has to question this assumption.
Cows eat grass and other plants, both low lying and from bushes. Given free access, they roam and eat according to what they need. This then gives us a clue as to the food responsible for strong bone growth.
Green leafy vegetables
Green leafy vegetables are a powerful source of nutrients including all the macro minerals, trace elements, amino acids, omega 3 and more. Green leafy vegetables are the best source of the macro minerals (calcium and magnesium) responsible for good bone growth.
Many believe that the oxalic acid in greens inhibit the uptake of the macro minerals. If the greens are varied each day, this is not a problem, as greens contain an over abundance of the minerals that oxalic acid leaches out. Other common foods that contain high levels of oxalic acid include tea, coffee, chocolate, grains, beans and some nuts.
You only need to look as the body parts of a human to realize that, although an omnivore, humans are much closer to herbivores than to carnivores.
For example:
- Human teeth are blunt, similar to that of a herbivore
- Human finger nails are blunt, making it impossible to grasp a prey, as only a carnivores claws can
- The human face profile is straight, making it impossible to hold a prey – only an extended jaw can achieve this
- The human intestines are long as plant food takes longer to digest than raw meat
- Human saliva contains ptyalin, common to all herbivores, but absent in carnivore saliva
- The stomach acid of carnivores is much stronger than that of herbivores – human stomach acid is similar to that of herbivores
- Carnivores perspire through their paws and by panting – herbivores perspire through skin pores
This means human health will fare better on a diet that is similar to that of a herbivore.
Processed Milk Causes Disease
The common practice of pasteurizing and homogenizing milk is the cause of many diseases, according to an increasing number of health therapists. Milk is pasteurized in an effort to prevent the spread of tuberculosis. However, in a study where 70 children were given a pint of raw milk every day over a five year period, only one case resulted. In a similar study involving pasteurized milk, 14 cases resulted.
Dr. Kurt Osler is a cardiologist in Connecticut. He has been researching the effects of homogenized milk for over 20 years. His findings indicate that homogenized milk is responsible for high cholesterol. Dr. William Ellis, an osteopath, links cows milk to many diseases in both children and adults such as chronic fatigue, anemia, arthritis, cramps, obesity, allergies and heart problems. Dr Frank Oski, a pediatrician, cites cows milk as being linked to iron deficiency anemia, cramps, diarrhea, multiple forms of allergy, atherosclerosis and heart attacks.
If milk was such a great source of calcium for the body, then osteoporosis should be minimal in countries which consume the most dairy. Instead, it’s the opposite.
There are so many common myths that are harmful to your health. Don’t accept them at face value.

Getting the most nutrition for your money isn’t as hard as you may think. To come up with the list of healthy foods below, Consumer Reports consulted a number of nutrition experts and food scientists. The foods are grouped by nutrient—antioxidants, calcium, fiber, omega-3’s, and protein—to make it easier to plan meals.
Whenever possible, select items that are labeled USDA certified organic, but note that the prices below are for conventional items.

Antioxidants—cheap ways to get a super nutrient fix
Cabbage – 16 cents per serving (½ cup cooked); $2.50 for one medium head (4 pounds).
Usually the cheapest member of the super-nutritious cruciferous family that includes broccoli and Brussels sprouts, cabbage is loaded with Vitamins A and C plus cancer-fighting sulforaphane.
Canned unsweetened pumpkin – 38 cents per serving (½ cup); $1.32 per 15-ounce can.
The bright orange hue is a tip-off to high levels of beta carotene, an antioxidant that might help protect vision. Skip the sweetened purees, which can be full of calories.
Dried plums – 31 cents per serving (¼ cup); $3.99 per 18-ounce container.
Often a little cheaper than its healthful cousins — dates, figs, and dried apricots — this concentrated version of a ripe plum packs antioxidants, fiber, and potassium. Portions are less because it is concentrated according to experts.
Frozen blueberries – 66 cents per serving (½ cup); $3.29 per 12-ounce package.
Keep a stash of these powerhouses in your freezer. They have been associated with the prevention of Alzheimer’s, diabetes, cancer, and heart disease, according to experts.
Kale — 37 cents per serving (1/2 cup); $1.49 per bunch (about a pound).
Dark, leafy kale and other greens (collards, mustard greens, and Swiss chard) are sometimes cheaper than lettuce mixes and packed with Vitamins A, C, and E.
Canned tomatoes – 28 cents per serving (1/2 cup); $1.99 per 28-ounce can.
Heat-processed canned or boxed tomatoes contain more of the antioxidant lycopene than fresh ones. To keep sodium down, buy those with no salt added.

Calcium—feed your bones for less than $1 a serving
Canned salmon with bones – 32 cents per serving (1/4 cup); $2.24 per 14.75-ounce can.
The soft, edible bones are loaded with calcium, plus it’s a superstar for heart-healthy omega-3s (see below). To cut calories, look for salmon packed in water and to avoid mercury and other toxins, choose a wild Salmon variety.
Plain yogurt – 70 cents per serving (6-ounce container); $8.39 per case of 12.
Yogurt is a quick and handy way to get calcium. It’s also brimming with protein and good bacteria that aids digestion. To flavor it for fewer calories, stir in a bit of your own vanilla extract or all-fruit spread.
Nonfat dry milk powder – 17 cents per reconstituted cup; $5.99 per 26-ounce container.
This is just milk that has had the water removed, so it equals the calcium and protein of regular milk for around 10 cents less per serving. (3 tablespoons equals 1 cup of milk.)

Fiber—stay regular for less than 50 cents a serving
Edamame and green peas – 25 cents per serving of peas ( 1/2 cup) and 90 cents per serving of edamame (1/2 cup); $1.99 per 16-ounce bag (frozen peas) and $2.69 per 16-ounce bag (frozen edamame).
These legumes have a good amount of fiber and protein—about ¾ cup of peas has more protein than an egg.
Rolled Oats – 28 cents per serving (1/2 cup); $3.59 per 18-ounce container.
Because these fiber heavyweights soak up more water than instant oatmeal, they fill you up more, so you eat less. They’re also gluten-free. To shorten cooking time, you can soak rolled oats in milk overnight in the fridge and pop them in the microwave the next day.
Whole-grain spaghetti – 23 cents per serving (2 ounces); $1.59 per 13.25-ounce box.
When it comes to fiber, not all whole-grain pastas are equal. Check the package—a serving should have 5 grams of fiber or more. Use instead of white pasta.
Quinoa – 50 cents per serving (1/4 cup); $3.99 per 12-ounce package.
Quick-cooking quinoa has almost 50 percent more fiber than brown rice, plus a dose of protein; one cup of cooked quinoa has more protein than an egg, according to the experts.
White potatoes – 13 cents per serving (1 medium spud); $1.99 per 5-pound bag.
Do your health a favor and eat your potatoes unpeeled, which will give you another gram of fiber for every small potato.
Popcorn – 12 cents per serving (1/4 cup unpopped); $1.89 per 28-ounce bag.
It’s a fun and easy way to get some fiber; research shows that popcorn eaters get about 22 percent more fiber than non-popcorn eaters. But don’t pile on calories with butter.

Omega-3s—heart healthy bargains
Frozen shrimp – $1.36 per serving (3 ounces); $14.99 per 2-pound bag.
Though not as high in omega-3s as sardines, frozen shrimp is a good, low-calorie, and relatively cheap source. Look for U.S.-farmed freshwater shrimp, one of the most sustainable seafood choices on the market.
Canned sardines in water – $1.59 per serving (3.75-ounce can).
On the eco-friendly list of fish and a health bargain not to be missed, sardines (with bones) are rich in heart-healthy omega-3s and bone-saving calcium. The healthful fats in fish are also linked to arthritis relief, according to the experts.
Flaxseed – 11 cents per serving ( 3 tablespoons); $1.79 per 16-ounce bag.
This mighty seed has omega-3s and other fatty acids linked to immune-system strength, cardiovascular health, and cancer prevention. Be sure to grind the whole seeds so that they can be digested properly.
Tofu – 48 cents per serving ( 3 ounces); $2.39 for 14 ounces.
Tofu is an American Heart Association-recommended source of omega-3s. It’s also cholesterol-free and high in protein. Silky soft tofu is best suited to soups and desserts.

Protein—fuel up for as little as 18 cents
Dried brown lentils – 27 cents per serving (1/2 cup); $1.45 for 16 ounces.
Quick-cooking lentils need no soaking, so they’re easy to prepare. They’re a good source of protein, fiber, and folic acid (important for pregnant women).
Eggs – 18 cents per egg; $2.19 per dozen.
A large hard-boiled egg is packed with 6 grams of protein. Although eggs contain cholesterol, they aren’t high in saturated fat (which increases LDL levels), making them OK to eat regularly even when you’re trying to reduce your bad cholesterol.
Frozen turkey – $1.59 (per pound).
Don’t wait for the holidays! Frozen birds are a good deal all year. The ratio of lean to fatty meat is a trim 2:1, and there’s less saturated fat than in beef or pork.
Dried black beans – 24 cents per serving (1/2 cup); $1.45 for 16-ounce bag.
All beans (such as navy, cannellini, and pinto) are stellar sources of protein, fiber, and blood-pressure-friendly potassium, but darker beans pack more nutrients. Draining and rinsing reduces sodium.
Peanuts in the shell – 12 cents per serving (small handful); $1.99 for 16 ounces.
They’re a cheap protein fix, and they shell out more than 30 essential nutrients and phytonutrients, including resveratrol, a phytochemical linked to a reduction in heart disease and cancer risk.

Perdre du poids: motivation, satiété et quantité
Motivation
« Quand la motivation est externe et axée sur les résultats, la perte de poids est plus difficile à maintenir à long terme, a souligné la psychologue. Une personne qui reprend 1 kilo après en avoir perdu 5 risque de se décourager si sa motivation est axée sur les résultats. À l’inverse, un individu qui s’attarde au processus va tenter de comprendre ce qui s’est passé. Il peut réaliser, par exemple, qu’il a vécu une semaine stressante, ce qui l’aidera à faire des liens utiles à long terme. »Sommeil et calcium
