Nutrition

Nutrition is the set of processes by which a living being processes food to ensure its functioning.

Food definition

Since nutrition focuses on the relationships between living organisms and their foods, it is necessary to define what is considered a food.

Nutrients

There are many different nutrients, divided into two categories: macronutrients and micronutrients.

Micronutrients

The body derives its energy in sugars (or carbohydrates), fatty substances (or lipids) and proteins. These three energy nutrients form the class of macronutrients.

17 anti-cravings tricks to pay attention to its line



Difficult to resist sweets in case of small (or large) hollow. And nibbling, we know, is not the best friend of our line. So how can we end our hunger without damaging the balance? Here are 17 tips to fight our cravings.

1. Do not skip meals!


 A meal sautéed = excessive appetite and storage ensured at the following meal.To avoid this, make 3 full meals a day, without neglecting breakfast, the meal that sets the tone (so be careful not to eat too many quick sugars that would boost blood sugar).Prefer vegetables, fiber and vary protein. Cheese, vegetables, olive oil, almonds, meat (preferably not red), fish, canned sardines ... are your allies.

2. Eat at fixed times 


Your body has an internal clock and this one does not appreciate much the jet lags. Be as regular as possible so that your stomach gets used to receiving such a quantity of food at such time.Little by little, you will not even think about snacking!

3. Do not eat with a slingshot 


So that the stomach sends a message of satiety to the brain, it takes at least 20 minutes: that's why a meal too quickly engulfed will not satisfy you. Savor foods and chew them for a long time.

4. Do not shed snacks 


Making a snack is not nibbling! On the contrary, these snacks calm the feeling of hunger and prevent you from throwing yourself on the food during the next meal. Yes, snacks, they have everything good! Finally, if they are well chosen: a fruit not too sweet and a yogurt nature, or a yoghurt natural oleaginous (almonds, hazelnuts) ample enough! A slice of ham or a hard boiled egg also constitute super good snacks slimming.

5. Not in front of the TV (or the computer) 


When you are facing the screen, you eat mechanically: not only do you eat more, but you also do not remember and tend to nibble further. In short, when you eat, do just that.

6. Drink a large glass of water


 Or herbal tea, or broth. And wait 10 minutes.If after this period, you do not think your stomach is that this was only an impulse. However, if you hungry again, is that your body craves a snack. But beware, the more you think to eat, the more it opens hunger. The effect is perverse.

7. Monitor the glycemic index (GI) of foods 


The glycemic index or GI determines whether a food rich in sugars will satisfy you long or not.If the index exceeds 50, the food causes excessive insulin secretion and promotes the storage of glucose in the form of fats. Run away !And conversely, the lower the GI, the slower the diffusion of carbohydrates in the blood, and the longer the feeling of hunger is felt.

> For information, GIs for certain foods: 

French fries: 95 
Raisins: 65Bananas: 60
 Spaghetti al dente: 40 
Peanut butter without added sugar: 40
 Dried figs: 35 
Green Beans: 30 
Dark chocolate: 25 
Namely: cooking mode plays on the glycemic index (GI) of food

8. Do not get hurt by the light 


A drink with sweetener brings you the taste without the calories. It can relieve a little craving but this false sugar can also give you even more desire for sugar, with the risk that you then throw yourself on the real ...

9. Prefer the "complete" 


Cereals, bread, pasta, whole rice ... rich in fiber, vitamins, minerals, "complete" foods are much more satisfying and less caloric than so-called "classic" foods (white bread ...).

10. Discover agar agar 


The agar agar is a gelling agent sold in the form of a powder of algae in the pastry department of the supermarket. To use as an appetite suppressant, dilute 2 grams in your milk or tea and boil. And drink, as if nothing had happened. In the stomach, agar agar turns into jelly and swells, bringing you satiety, without calories.

11. Eat green vegetables at the start of a meal 


The fibers contained in the voluminous green vegetables help to achieve satiety more quickly. Then, by slowing down digestion, they slow down the assimilation of sugar, which helps avoid the insulin spikes and the storage that goes with it.

12. Think about the natural appetite suppressant 

The apple is a real ally. Its high content of pectin, which swells on contact with water, fills the stomach. But be careful, an apple does not replace a meal. Also, be aware that it is one of the foods most loaded with pesticides, so eat it preferably organic.Another anti-munching fruit: grapefruit. And in addition, it is full of vitamin C!Otherwise think of the konjac with the chia seeds swollen in a vegetable milk .... everything that swells without calories.

13. Do you mind 


Breathing a soothing odor on a handkerchief will allow you to calm your cravings for nibbling. However, choose a different scent from the one you wear.

14. Conceive a smart snack 


Roll up the whites in snow and mix them with a yogurt (plain). Here is a hyper-filling and low-calorie snack.Or a smoothie without sugar, mixing fruit and vegetable. A little thick, with water, enough to stall. To eat only freshly prepared, otherwise it is without great interest!Otherwise a handful of oilseeds with a natural yoghurt, this is a great snack.Tip: Gretel can help you snack without feeling guilty. More info here.

15. Sleep! 


It has been known for about ten years that sleep has an impact on weight gain. Indeed, lack of sleep decreases the production of leptin or satiety hormone (hormone generated by the brain) and increases that of ghrelin which on the contrary opens the appetite. So now you know what to do! 
16. Do not diet!

 Because the very idea of ​​restricting yourself can cause the urge to eat more.Try instead to adopt a balanced diet with a few small deviations from time to time to never feel frustrated.If you feel lost, it's worth seeing a nutrition professional. 
17. And finally, eat your hunger! 

Ok, sometimes you think your body is hungry while it is your head that claims. But do not forget that hunger is sometimes a true hunger ... and remember that you will not fat if you eat when you need it.

3 supplements to try against acne




By acting on inflammation, hormones or even mediators of growth hormone, supplements can give results against acne. 

Probiotics :

Studies on the intestine-brain axis are now numerous and we know that our intestinal microbiota influences, for example, our mental health. But what we know less is that there is also a link between our intestines and the health of our skin. This is what a new study in the journal Beneficial Microbes suggests. The researchers show that probiotic supplementation improves acne in adults and evoke the existence of an intestine-skin axis that could target the gastrointestinal tract with bacterial strains to improve the physiology of the skin.
 
"Acne is a chronic inflammatory disorder characterized by a number of different skin lesions. The pathogenesis of acne is complex and involves an increase in sebum production and hyperplasia of the sebaceous glands "explained the authors. "More and more data suggest that alterations in insulin signaling are implicated in the pathogenesis of acne in adults.""Insulin and IGF-1 (Insulin like Growth Factor) could exercise actions that promote acne. An increase in serum IGF-1 levels is associated with an increased risk of acne in women after adolescence.

 
On the other hand, the research carried out on the strain Lactobacillus rhamnosus SP1 (LSP1) shows that this probiotic normalizes the cutaneous expression of certain genes involved in the signaling of insulin.This small pilot study was conducted on 20 adult sufferers of acne. During a 12-week period, a first group of 10 people received supplementation with LSP1 probiotics. The other group received a placebo. Skin biopsies were performed at the beginning and end of treatment and researchers evaluated gene expression for IGF1 as well as FOXO1 transcription factor, a relative deficiency of which would play a key role in the pathogenesis of The acne. The clinical efficacy endpoint is the overall improvement rate on a 5-point scale.At the end of the study, the group taking probiotics showed a 32% decrease and a 65% increase in the expression of the genes coding respectively for the IGF1 growth factor and the FOXO1 factor."Our results show that 12 weeks of supplementation in LSP1 have allowed to normalize the dermal expression of the genes involved in the signaling of insulin in the areas of acne. This molecular change is accompanied by a significant improvement in the appearance of acne. This treatment is safe and well tolerated, "say the researchers.The exact mechanism by which probiotics normalize the expression of IGF1 and FOXO1 in the skin is not known but it is possible that probiotics improve insulin resistance through direct metabolic effects or by correcting An intestinal dysbiosis. 


Soy isoflavones 
The soy isoflavones are "phytoestrogens" (genistein and dadzein), which can behave like antiandrogens, in particular inhibiting an enzyme, 5-alpha-reductase, which transforms testosterone into dihydrotestosterone (DHT). In a double-blind, 12-week controlled study, researchers have shown that a soy extract with 160 mg of isoflavones has beneficial effects on acne, presumably by decreasing the level of DHT. 

Green tea extracts
 Green tea contains polyphenols called catechins, which are anti-inflammatory. A double-blind study tested the effects of a supplement of epigallocatechin gallate green tea (EGCG) on acne for 4 weeks (1500 mg decaffeinated extract) on 64 women aged 25 to 45 years. Compared with placebo, the supplement allowed a significant improvement in acne lesions.
