Spinach is very rich in iron and 9 myths about food

It is true that many older people have little appetite, sometimes due to digestive or metabolic problems, stress, or even depression. 

Spinach is very rich in iron and 9 myths about food
sources of iron

But this must absolutely be remedied by offering seniors a balanced diet, vitamins, and protein and avoiding any monotony, to meet nutritional needs and energy expenditure that are not reduced by age. 

Without forgetting the pleasure of eating, which is important to preserve: a piece of cake or a glass of wine, if possible in good company.

Olive oil is the best fat

Without denying its beneficial properties - it's mono and polyunsaturated fatty acids play an important role in the prevention of coronary heart disease -, it is relatively low in omega-3 prized by nutritionists. They recommend mixing two oils daily, olive oil and rapeseed, for a good omega-3-omega-6 ratio. And be careful not to heat them to too high temperatures. Finally, there is no point in demonizing butter and crème fraîche, if their consumption remains moderate.

UHT preservation process preserves all vitamins

The UHT (for high temperature) process involves heating the milk for 5 seconds to destroy microbes and deactivate enzymes. In doing so, some of the vitamins A and B contained in cow's milk are destroyed. But this loss is limited, and the advantages of the process (destruction of pathogens and long storage) have ensured its success with consumers.

4. Spinach is very high in iron

Not really. In any case, much less than lentils (3.3 mg / 100 g), black pudding (20 mg / 100 g) and algae (more than 100 mg / 100 g)! It is to a mistake of the secretary of the German biochemist Emil von Wolff, who worked on the nutritional data of foods, that we owe this legend: a misplaced comma, and the iron content of spinach, of 2.7 mg / 100 g, has become 27 mg / 100 g! It was 1870 ... and Popeye's arrival to iron-doped muscles strengthened the belief.

Better to drink green tea than black tea

Not exactly. Consumption of both teas is good for your health, although green enjoys a particularly favorable image with the public. Its dried but unfermented leaves are indeed rich in antioxidants: polyphenols, catechins, and in particular a beneficial substance called EGCg. As the fermentation process that creates black tea transforms this compound, we quickly concluded that green tea was better. However, it has been discovered that thearubigins, substances that give black tea color and taste, are also antioxidants. The positive effect of these molecules against heart disease remains to be confirmed. You might as well choose your tea according to your tastes.

Eating soup makes you grow taller

Not at all. Children who are hit with this saying know well that it is a low parental maneuver to make them swallow vegetables ... Which, vitaminized, are good for growth, but certainly not capable of you on their own save a few centimeters. Proteins are the real fuel for growth during adolescence, whether of a plant (legumes) or animal (meat, eggs, etc.) origin.

Oysters are too high in cholesterol

Not really. They contain around 50 mg per 100 g of product (in comparison, 80 mg for three small ribs of lamb), which is a moderate amount. Above all, oysters are rich in polyunsaturated fatty acids, especially those of the omega-3 family, which are good for heart health. It is therefore not relevant to exclude them, especially as they provide us with vitamins from group B, minerals, and trace elements.

Grapefruit is full of benefits

Not all the time. As a juice, it should be avoided by those taking certain cholesterol medications, including simvastatin. Likewise, for immunosuppressants prescribed against transplant rejection. The reason: grapefruit juice can increase the absorption of certain drugs in the body, and therefore increase side effects. It is recommended that you avoid drinking juice for two hours before taking medication and limiting its consumption. And especially to talk to his doctor.

Food additives are carcinogenic

Not really. For years, a document on supposedly carcinogenic food additives from a mysterious "Villejuif hospital" has been circulating in France. The information it contains is false. The health authorities point out that each additive is subject to official authorization after studies on its safety. This does not mean that these products, which are widely used by the food industry (dyes, antioxidants, texture agents) are not sometimes problematic for our health. For example, some can cause allergies, and others, suspected of causing disturbances and are monitored by health authorities.

Goat's milk is the best

Goat's milk has become very popular with the public because its composition is closest to human breast milk. It is slightly richer in protein than cow's milk and is better supplied with vitamins and minerals. But it is also fatter. In addition, the consumption of goat's or sheep's milk can cause allergies (different from those related to cow's milk).
