Research Question:

Allium-eating vegetables lowers the chances of getting stomach cancer?

Study Design:
This overview article contained 22 case-control studies and cohort studies with more than 10000 cases together 4.

Results and conclusions:
The researchers found 4 in 10 case-control studies and cohort studies, that a high intake of allium vegetables compared to a low, the chance of getting stomach cancer significantly with 12% [95% CI = 0.67-0.91] reduced.

The researchers found in 4 cohort studies, that a high intake of allium vegetables compared to a low, the chance of getting stomach cancer non-significant with 2% [95% CI = 0.88-1.18] increased.

The researchers found in 12 case-control studies, that a high intake of garlic compared to a low, the chance of getting stomach cancer significantly with 40% [95% CI = 0.47-. 76] reduced.

The researchers found in 13 case-control studies, that a high intake of onions compared to a low, the chance of getting stomach cancer significantly with 45% [95% CI = 0.41-0.73] reduced.

The researchers concluded that eating allium vegetables, garlic and onions in particular, the chance of getting stomach cancer probably reduced. Probably because the reduced risk was not found in cohort studies.

Allium groenten

  • Allium is the Latin name for look, a genus mainly of ground with worldwide almost seven hundred varieties. Most alliums are bulbous plants.
  • To the Allium vegetables include garlic, onions, shallots, spring onions, chives and leeks. The typical smell of Allium vegetables is caused by sulfur-containing compounds. This sulfur-containing compounds have antioxidative effect.
  • When cutting an onion makes the knife a number of cells is broken. The enzyme allinase comes in contact with the aminozuursulfoxides and aminozuursulfoxides under the influence of oxygen by the enzyme allinase using pyridoxal phosphate converted to 1-propeensulfeenzuur. This 1-propeensulfeenzuur is in turn converted to LPG: syn-propaanthial-S-oxide. This gas is ultimately responsible for the watery eyes.
  • The organic sulfur compounds responsible for the typical smell and taste of onions are diallyl disulfide, diphenylthiosulfinate, quercetin and allicin.
  • Garlic contains 33 sulfur-containing compounds. Allicin is considered to be the most important bioactive sulfur compound in garlic. When garlic is chopped or crushed, put the enzyme allinase (present in garlic) Tasha (present in intact garlic) into allicin. The typical smell of cut garlic comes from the breakdown products of allicin.
  • Tasha 1 mg is equal to 0.45 mg allicin.
    1 gram of garlic delivers 2.5-4.5 mg allicin. So a clove of garlic by 2 grams delivers 5-9 mg of allicin.
  • The typical garlic smell in the mouth after eating garlic is caused by the sulfur compound allylmethylsulfide.

Scientific studies on Allium vegetables:
The review articles (meta-analyses) of randomized, placebo-controlled double-blind human studies (Rcts) answer the following question:
"Is swallowing food supplements make sense?". Yes at a positive conclusion and no in the case of a negative conclusion.

The review articles (meta-analyses) of cohort studies or case-control studies answer the following question:
"Should I change my diet?".

  1. Garlic and onions probably reduce stomach cancer
  2. Garlic supplements reduce blood pressure
  3. Garlic supplements reduce cholesterol levels for 2 months in people with high cholesterol
  4. 6 cloves of garlic per week reduces possible colon cancer and stomach cancer
  5. 600-900 mg of garlic supplements per day lowers blood pressure
  6. At least 20 grams of Allium vegetables per day lowers stomach cancer
  7. Allium vegetables may reduce prostate cancer

Research Question:
Drinking alcohol reduces the chance of getting Parkinson's?

Study Design:
This overview article contained 32 items with 677550 participants, of which 9994 people with Parkinson's disease.

Results and conclusions:
The researchers found that after having corrected for smoking, a high alcohol consumption compared to a low, the chance of getting Parkinson's disease significantly with 22% [RR = 0.78, 95% CI = 0.67-0.92] reduced.

The researchers found that after having corrected for smoking, a high alcohol consumption compared to a low, the chance of getting Parkinson's disease in prospective cohort studies significantly with 14% [RR = 0.86, 95% CI = 0.75-0.995] reduced.

The researchers found that after having corrected for smoking, a high alcohol consumption compared to a low, the chance of getting Parkinson's disease in matched case-control studies significantly with 26% [RR = 0.74, 95% CI = 0.58-0.96] reduced. Significant is, there is a link at a 95% reliability.

The researchers found a significant Association for beer in the sensitivity analyses [RR = 0.59, 95% CI = 0.39-0.90], but not for wine or liqueur and among men [RR = 0.65, 95% CI = 0.47-0.90] but not among women. Significant because RR of 1 was not in 95% CI of 0.47 to 0.90. RR of 1 is, there is no risk.

The researchers found that every glass of alcohol a day, the odds of getting Parkinson's disease with non-significant 5% RR = 0.95, 95% CI = 0.89-1.02, p for non-linear = 0.85] reduced.

On the basis of the found results the researchers concluded that drinking alcohol, especially beer the chance of getting Parkinson's disease, especially among men decreased.

Geen toegevoegde suikers van Karvan Cévitam 75% fruit sinaasappel voldoet niet aan de wettelijke eis!

Vanessa Cafe 75% Orange

Product:
Karvan Cévitam 75% fruit orange.

Details:
The product does not contain any dyes and no added sugar.

75% fruit Orange:
The product is called 75% fruit. But what does 75% fruit anyway?
When consulting the ingredients list falls to read that 75% 75% fruit juice from fruit juice concentrate State. But what is meant by the law under fruit juice concentrate? Fruit juices in the Decree States that fruit juice from concentrate:
goods which is obtained by adding again to concentrated fruit juice:

  1. the amount of water extracted from that juice during concentration;
  2. the disappeared from the juice but during the production process of the fruit juice, or of the fruit juice of the same kind, retrieved on flavourings; and
  3. where appropriate, pulp and cells;

In other words, for the law is nothing but fruit juice concentrate concentrated juice with hardly any water, fibres, vitamins and aromas. In other words, fruit juice concentrate not on fresh fruit seems to be in the vertste! So the word "fruit" on the package does not have the same meaning as fruit from a fruit basket!

The product is called 75% fruit orange. The name gives the suggestion that this product from 75% Orange exists. When consulting the ingredients list falls to read that 75% fruit Orange from only 26% Orange exists.  The remaining 49% is Mandarin, Apple and rosehip. But how many percent Mandarin is in this product anyway?
The ingredients list shows that the word "Mandarin" for the word "orange" State. That is, the percentage of Mandarin orange in this product is higher than the percentage. In other words, 75% fruit Orange consists of more than 26% Mandarin or there is more Mandarin than orange in 75% fruit Orange!
So 75% fruit orange is a misleading name and is therefore inconsistent with the food law.
As a consumer's good to know that the order of the ingredients in the ingredients list is established by law. The ingredients list always starts with the ingredient that the largest percentage in the product delivers and ends with the ingredient with the lowest rate in the product.

Mandarin and Apple juice concentrate are cheap fruit juice concentrates and are therefore often used to sapgehalte up to the legal requirement. The legal claim in this case is 75%.

The manufacturer claims that this product in Orange (hence the name 75% orange) is the percentage of the law and so he has orange in the ingredients list release. He claims also that in this product not Mandarin, Apple and rosehip is he of the law and therefore the percentage of Mandarin, Apple and rosehip also not to release.
As a consumer's good to know that the manufacturer against releasing the percentage in the ingredients list. Releasing the percentage that makes the product easy to duplicate and that the manufacturer does not!

15% RDA vitamins:
In this product are 5 vitamins that each delivers 15% RDA per 100 ml (see table nutritional value per 100 ml). 15% RDA per 100 ml is the minimum legal requirement to be able to claim that vitamins in the product. In other words, when the manufacturer vitamins (but also minerals) to add a product, he must always add at least 15% RDA per 100 ml.
Hence, the consumer often 15% AHD on the packaging encounters.
That this product artificially (i.e. not submitted by fruit juice concentrate) vitamins is added, can be seen in the ingredients list. What in the ingredients list will be artificially added during production. In the ingredients list of this product is that the word "vitamins" to read.
It is cheap vitamins from a bag than fruit juice concentrate.

15% RDA betrays that the manufacturer is not so much to the health of consumers. Because if he really gives the health of consumers then he has added more than 15% RDA per 100 ml. But that he has not done. The reason behind this is, it's not so much how many vitamins the manufacturer in the product. It comes to him before the word vitamin to put on the package and that should not take the law from 15% RDA.

The RDA of vitamins on the packaging is submitted by the consumer goods Act and not by the Health Council of the Netherlands. In other words, as a consumer, you have nothing to the RDA on the packaging because the AHD of the commodities Act does not always reflect those of the Health Council of the Netherlands! The AHD of the Health Council of the Netherlands can be found on the website of the food centre.

Citric Acid:
In this product about acidifier citric acid. Acidifier is for the law an E-number. Citric acid is necessary for the product to a requirement to bring around acidity of 3.5. An acidity of around 3.5 is required to give the product a few months. In other words, an acidity of 3.5 is a conservation technique.

Although the product has a pH of around 3.5, tastes the product is not acid. That's because the sugars in this product the sour taste masking. Buttermilk, for example, has a pH of 4.4, much higher than 3.5 and yet tastes like buttermilk acid. That's because in buttermilk no sugars that the sour taste masking.

As a consumer's good to know that when in a product citric acid or carbon dioxide is, also always sugars, sweeteners or citrate are. Sugars, sweeteners and citrate can namely the sour taste, caused by carbonic acid citric acid or masking.

Potassium Sorbate:
The product contains the preservative potassium sorbate. Potassium sorbate is a cheap preservative and is therefore often used. Because the amount of citric acid is not sufficient to give this product a few months is potassium sorbate added.

As a consumer's good to know that the food industry multiple techniques (adding citric acid, carbonic acid and potassium sorbate) used to preserve a product.

This product contains a preservative but preservative consumer has a negative image. Therefore "contains a preservative" on the package left out!

No sugar added:
On the packaging is to read "no sugar added". No sugar added is a nutrition claim and the manufacturer may only put this nutrition claim on the package when he during production no sugar in the form of sucrose, glucose and/or glucose fructose syrup has added. But the ingredients list shows, however, that the manufacturer during production have such sugars sucrose and glucose fructose syrup in the form added. In the ingredients list, namely the word "sugar or sucrose" and "glucose-fructose syrup" to read.
In other words, the manufacturer violates the law here because the "nutrition claim" no sugar added "meets does not meet the legal requirement. This is a gross error and NVWA will the manufacturer on the fingers have to click!

Is there E-numbers in?
Yes in this product are 4 E-numbers. Is citric acid E330, vitamin C is E300, potassium sorbate is E202 and vitamin E is E309.

Vitamins are food industry E-numbers!

What is healthier?

Sportvoeding

Athletes who have no healthy and varied food, vitamin and mineral supplements required. Vitamin and mineral supplements can not directly increase the sport performance. They can shorten the recovery period between workouts by.

When you swallow food supplements anyway, then it's good to know, that:

  • The operation depends on the dosage and the duration.
  • The recording never 100%. So is the inclusion of L-carnitinesupplement 15-20%. That is, when you 300 mg L-carnitine swallows, then the body has only 45-60 mg included. The manufacturer is not required to mention how much of a food supplement is included in the body eventually.
  • Dietary supplements are not always doping free. Doping free nutritional supplements on this website.
  • Vitamins and minerals increase the sports performance not directly but indirectly. Swallowing vitamins and minerals can shorten the recovery period.
  • The operation is found when a positive conclusion is really pás in an overview article of randomized, placebo-controlled, double-blind human studies or when the claim has been approved by EFSA.
  • NOC * NSF has approved the operation of a number of nutritional supplements.

Swallow while exercising no supplements. They affect the sport performance.

It has been scientifically proven that water, sugar, creatine and caffeine intake during exercise increase the sport performance.

Power supply with less than 55% carbohydrates And 20% fat and/or less has adverse impact on the sport performance.

At a low-carbohydrate diet ( 5 grams of carbohydrate per kg of body weight) can take up to 2-3 days after exercising the glycogen supply is again at the previous level.

Building up the glycogen and creatine inventory:
Get athletes during exercise mainly energy from carbohydrates that are stored as glycogen in the body. For the sport that needs lots of energy in a very short time, is creatine also an important energy supplier. Therefore, it is recommended that you briefly a competition the glycogen and creatine to build inventory.

Build up the glycogen supply is done via the tape ring off method of 3 days for a competition. The carbohydrate intake during this 3 days is 7-10 grams of carbohydrate per kg of body weight per day.

Refurbishment of the creatine inventory in the body is done in 2 phases: the load and maintenance phase. Creatine can best be taken with carbohydrates. The 2 ways to creatine to build inventory are:

  1. 0.3 grams of creatine per kilogram body weight per day (5-7 grams of creatine per times with an interval of 3-4 hours) and that 3-7 days long. After 3-5 grams of creatine per day for 4-10 weeks long.
  2. 2-3 grams of creatine per day and that 30 days long.

The glycogen resynthesis (supplementing the glycogen supply weather after exercise) is the fastest within 30-60 minutes after exercise. The rate of glycogen resynthesis reaches its maximum at 0.8 grams of carbohydrate per kg body weight per hour.

During 24-48 hours after exercise the muscle and bone growth takes place.

It is a misconception that isotonic sports drink is absorbed faster than hypotonic sports drinks. The sugar content and the type of sugar turn out of essential significance.

Rehydration drinks serve a mOsm/l from bottom to have 500 osmolality, preferably below 300 and a sugar content of 40-80 grams per litre. Rehydration is replenishing moisture during a physical effort.

Isotonic sports drink has an osmolality of around 300 mOsm/l and a sugar content of 40-80 grams per litre. During exercise is the preferred isotonic sports drink and is hypertonic sports drink (> 80 grams of sugar per liter) discouraged. The osmolality of our blood is about 275-300 mOsm/l.

Sports drinks with 40-80 grams of carbohydrates and 280-660 mg sodium per litre is the fastest in the body. This is the ideal isotonic sports drink. Sports drink is recommended for the moderate sports longer than 60-90 minutes.

A sports drink or thirst quencher contains 40-80 grams of sugar per liter. A sports energy drink contains more than 80 grams of sugar per liter. It contains sugar also often caffeine, taurine and carbon dioxide.

There is internationally recommended to 250 ml fluid per 15 minutes during exercise (or 1000 ml of fluid per hour) in order to prevent dehydration, but also in order to be able to keep the sport performance. Furthermore, it is a scientific fact that the body up to 60 grams of carbohydrates per hour can break down to there, to get energy for exercise.

If you are energetic, during exercise means that you have eaten enough carbohydrates.

It is best between 2 and 4 hours before exercise to eat.

PAP in the legs indicates exhaustion of the glycogen.

The daily protein requirements of an athlete can be calculated as follows:
Daily protein requirements = fat free mass (FFM) x 2.75.

The resting metabolism (RMR) of an athlete can be calculated as follows:
RMR (Kcal/d) = (11.797 x weight in kg) + (6.487 x height in cm)-(5.180 x age) + (186.017 x gender (male = 1, female = 0))-139.444.

The common nutrient deficiencies among athletes are calcium, vitamin D and iron deficiency (often among female athletes).

How does the energy distribution during exercise look like?

Energy Distribution


Dietary advice when playing sports:

  • The last meal must have 2-4 hours for the sports are enjoyed.
  • Professional athletes are advised to choose products with at least 55 And 60-70% (and%) carbohydrates, And by 20-30% fat for products and for products with 15-25 and% protein or a daily diet with:

    15-25 and 20-30% protein, And fat, up to 10% And% saturated fat, up to 0.5 grams of sodium per 100 grams (100 ml), And a minimum of 25% simple sugars, at least 1.3 grams of fiber per 100 kcal and 60-70 and% (minimum 55 and%) carbohydrates.
     
  • Swallow dietary supplements only under expert guidance!
  • 0.5 mg vitamin B1 per 1000 kcal.
  • 0.6 mg vitamin B2 per 1000 kcal.
  • 0.02 milligrams of vitamin B6 per gram of protein consumed.
  • The recommended daily dose is 6 mg magnesium per kg body weight.
  • The recommended daily dose is 5-7 grams of carbohydrate per kg of body weight per day and koolhyrdaten 8-10 grams per kg of body weight during the tape ring-off period.
  • The recommended daily amount of protein for athletes is 1.2-1.8 grams per kg of body weight and for strength athletes is that 1.5 grams per kg of body weight during the maintenance phase and 2.0 grams per kg of body weight during the construction phase.
  • The rest metabolism can be calculated with the following formula:
    Resting metabolism (kcal/d) = (11.797 x weight in kg) + (6.487 x height in cm) – (5.180 x age) + (186.017 x gender) – 139.444.
    Sex should be completed at a 1 in men and in women a 0.

For the sports:

  • Drink the last 2 hours before the match 500-1000 ml moisture.
  • 5-30 minutes before exercise take 50 grams of carbohydrates.
  • Take 10 grams of protein right before exercising at because it promotes the recovery of the muscle damage.
  • Drink the last 3-5 minutes for the effort 150-300 ml water or thirst-quencher. This is called prehydration.

During exercise:

  • Take while exercising no more than 35 grams of fructose per litre because fructose is slowly taken up and therefore gastrointestinal complaints.
  • Drinking while exercising 125-250 ml of fluid per quarter.
  • Choose during exercise for a sports drink with an osmolality around 300 mOsm/l or below 500.
  • Avoid hypertonic sports drinks during exercise.
  • Drinking water during exercise, isotonic or hypotonic sports drinks. Isotonic sports drink has an osmolality of around 300 mOsm/l and a sugar content of 40-80 grams per litre. Hypotonic sports drinks has a sugar content of less than 40 grams per liter.
  • The optimal sports drink during sports is a sports drink with 6 g of sugar per 100 ml.
  • Drinking while exercising no coffee because coffee works vochtdrijvend allowing you to go to the toilet more often and thus lose a lot of moisture.

After exercise:

  • After exercise, there are 2 ways to replenish the glycogen supply:
    1. The first way: take directly (within 30 minutes) after exercise 1.2 grams of carbohydrates (preferably quickly absorbable sugars, such as glucose) per kg body weight. Repeat this every hour for 4-6 hours.
    2. The two way: 0.8 grams of carbohydrate per kg body weight + 0.4 grams of protein or amino acids per kg body weight per hour. Repeat this every hour for 4-6 hours.
  • It is recommended that after the effort 1.5 times the amount of water that is lost during the effort to complete.
  • Weighing you before and after exercise. Is your weight loss exceeding 1 kg then you have while exercising too little drunk. Each kg weight loss after exercise is equivalent to 1 liter of water. Moisture loss and-supplement is per sport different. Please consult a sports dietitian!
  • Take 10 grams of protein within 30 minutes after an intensive strength training in because it promotes the recovery of the muscle damage.

Stap 3: In kolom Gegeten op filter-icoon klikken, Clear Filter from "Gegeten" uitvinken, OK.
De 800 producten worden weer zichtbaar.
Stap 4: Eventueel filteren op producten met minder dan 35 En% vet, minder dan 10 En% verzadidg vet, minder 0.5 gram natrium per 100 gram en meer dan 1.3 gram vezels per 100 kcal.
Filter ongedaan maken: Clear filter uitvinken.
(Voorbeeld: filteren op producten met meer dan 1,3 gram vezels per 100 kcal. Klik op filter-icoon van kolom vezel per 100 kcal, Number Filters, Greater Than, 1,3 invullen, OK. Werk met komma of puntjes; afhankeklijk van uw toetsenbord (Nederlands of Engels)!).
Zo weet u zeker dat uw voeding altijd voldoet aan de richtlijnen van een gezonde voeding!
Stap 5: JA in kolom Gegeten invullen.
Stap 6: In kolom Gegeten op filter-icoon klikken, Filter, (Blanks) uitvinken, OK.
Uw gegeten producten worden zichtbaar.
Stap 7: De formule onderin geeft aan of uw dagelijkse voeding voldoet aan de richtlijnen van een gezonde voeding of niet.
Er wordt ook berekend wat uw voeding van de volgende dag mag zijn.
Stap 8: Mocht uw voeding op maandag 40 En% vet, 14 En% verzadigd vet, 0.2 gram zout per 100 kcal, 1.0 gram vezels per 100 kcal bevatten. Dan moet uw voeding van de volgende dag maximaal 30 En% vet, maximaal 6 En% verzadigd vet, maximaal 0.3 gram zout per 100 kcal en minimaal 1.6 gram vezels per 100 kcal bevatten.

Een gezond product mag voedingskundig gezien maximaal 35 En% eiwit, maximaal 35 En% vet, maximaal 10 En% verzadigd vet, maximaal 0.3 gram zout per 100 kcal, maximaal 25 En% eenvoudige suikers en minimaal 1.3 gram vezels per 100 kcal bevatten.

Een dagelijks gezonde voeding bestaat voornamelijk uit gezonde producten oftewel een dagelijks gezonde voeding (=het gemiddelde van alle dagelijks gegeten producten) mag maximaal 35 En% eiwit, maximaal 35 En% vet, maximaal 10 En% verzadigd vet, maximaal 0.3 gram zout per 100 kcal, maximaal 25 En% eenvoudige suikers en minimaal 1.3 gram vezels per 100 kcal bevatten.                                 

Een dagelijks gezonde voeding mag best ongezonde producten bevatten, mits er gecorrigeerd wordt voor het ongezonde deel van de desbetreffende producten.
Bijvoorbeeld: om weer op de richtlijn van 35 En% vet, waarvan maximaal 10 En% verzadigd vet uit te komen, moet een product met 50 En% vet en 15 En% verzadigd vet gecombineerd worden met producten die maximaal 20 En% vet, waarvan maximaal 5 En% verzadigd vet bevatten!

Een gezond gewicht is een combinatie van gezonde voeding volgens het 7-puntenprofiel én dagelijkse lichaamsbeweging.
15-30% van de dagelijkse calorie-inname (kcal) moet besteed worden aan de lichamelijke activiteiten.

 

 

 

 

Seleniumsupplementen verlagen depressie

Afbeelding

Onderzoeksvraag:
De resultaten van studies bij mensen met betrekking tot selenium en depressieve stoornissen zijn inconsistent en daarom werd dit overzichtsartikel uitgevoerd.

Verlaagt een hoge selenium inname (via voeding of voedingssuplementen) de kans op het krijgen van depressie?

Studieopzet:
Dit overzichtsartikel bevatte 20 studies (4 RCT’s, 9 cross-sectionele studies, 4 patiënt-controle studies en 3 prospectieve cohort studies) met in totaal 47164 deelnemers in de leeftijd van 18 tot 82 jaar.

Er was geen publicatie bias.
De RCT’s waren goed opgezet.

Resultaten en conclusies:
De onderzoekers vonden dat een hoge inname van seleniumsupplementen de kans op het krijgen van postnatale depressie significant met 3% [OR = 0.97, 95% BI = 0.95 tot 0.99, I2 = 0.0%, p = 0.507] verlaagde.

De onderzoekers vonden dat het slikken van seleniumsupplementen de kans op het krijgen van depressieve symptomen significant verlaagde [WMD = -0.37, 95% BI = -0.56 tot -0.18, I2 = 0.0%, p = 0.959].

De onderzoekers concludeerden dat een hoge inname van seleniumsupplementen de kans op het krijgen van postnatale depressie verlaagde. Verder, verlaagde het slikken van seleniumsupplementen de kans op het krijgen van depressieve symptomen.

Reumatoïde artritis

 

Hieronder vindt u wetenschappelijke studies (overzichtsartikelen) over de relatie tussen voeding en reumatoïde artritis:
Één zwaluw maakt nog geen zomer. Dus een énkele wetenschappelijke studie over een bepaald onderwerp zegt niet zoveel maar een overzichtsartikel (=een verzameling van wetenschappelijke studies over een bepaald onderwerp) van RCT's geeft wel antwoord op de volgende vraag:
”Is het zinvol om voedingssupplementen te slikken?”. Ja bij een positieve conclusie en nee bij een negatieve conclusie.

Één zwaluw maakt nog geen zomer. Dus een énkele wetenschappelijke studie over een bepaald onderwerp zegt niet zoveel maar een overzichtsartikel (=een verzameling van wetenschappelijke studies over een bepaald onderwerp) van (prospectieve) cohort studies of patiënt-controle studies geeft wel antwoord op de volgende vraag:
”Moet ik mijn voedingspatroon veranderen of niet?”.

  1. Vitamine E-supplementen verbeteren kwaliteit van leven van mensen met reumatoïde artritis

XXXXXXXXXXXXXXXX

  • Reumatoïde artritis (RA) is een chronische aandoening, waarbij uw gewrichten ontstoken zijn.
  • In de volksmond wordt reumatoïde artritis vaak reuma genoemd. Maar dat klopt niet helemaal. Reuma is een verzamelnaam voor meer dan 100 verschillende gewrichtsaandoeningen. Reumatoïde artritis is daar een van.
  • Er bestaan een paar grote groepen van reuma:
    • artrose, de meest voorkomende vorm van reuma in Nederland. Artrose is aandoening van het kraakbeen en bot van de gewrichten. Het kraakbeen, dat zorgt voor soepele beweging, neemt af of verdwijnt helemaal.
    • auto-immuunziekten/ontstekingsreuma, zoals reumatoïde artritis en jicht. Ontstekingsreuma is en auto-immuunziekte waarbij het immuunsysteem gezonde cellen aanvalt, wat zorgt voor ontstekingen in de gewrichten.
    • osteoporose
    • weke delen-reuma. Weke delen-reuma zijn aandoeningen aan de spieren, pezen of slijmbeurzen. De bekendste vorm hiervan is fibromyalgie.
  • Reuma is onvoorspelbaar. Het is een grillige ziekte.
  • Ruim meer dan de helft van alle reumapatiënten is jonger dan 65 jaar.
  • Reumatoïde artritis ontstaat doordat uw lichaam afweerstoffen maakt tegen uw eigen gewrichten. Die afweerstoffen (antilichamen) gaan aan de binnenkant van uw gewrichten zitten. Ze zorgen daar voor een ontsteking.
    Reumatoïde artritis wordt daarom een auto-immuunziekte – uw afweersysteem keert zich tegen uw eigen lichaam – genoemd.
  • Reumamedicijnen heten DMARD's (disease modifying drugs). Ze zorgen ervoor dat uw gewrichten minder snel of niet beschadigen door de ontstekingen.
  • Bij reumatoïde artritis is de stijfheid ’s ochtends het ergst. Of na lang liggen of stilzitten.
  • Bij reumatoïde artritis heeft u meestal dezelfde klachten links en rechts.
  • Genoeg bewegen is belangrijk om uw gewrichten zo soepel mogelijk te houden.
  • Reumatoïde artritis kan sluipend beginnen of plotseling ontstaan.
  • Reumatoïde artritis is geen erfelijke ziekte. Wel komt reumatoïde artritis soms voor bij meerdere mensen uit één familie.
  • De exacte oorzaak van reumatoïde artritis is niet bekend.
  • Reumatoïde artritis komt op alle leeftijden voor. Vrouwen hebben vaker reumatoïde artritis dan mannen.
  • Omgevingsfactoren hebben invloed op het ontstaan van reumatoïde artritis. Zo hebben mensen die roken een grotere kans op het krijgen van reumatoïde artritis dan mensen die niet roken.
  • Reumatoïde artritis verloopt bij iedereen anders. Meestal wisselen periodes waarin u veel klachten hebt zich af met rustige periodes waarin u spontaan minder klachten krijgt.
  • Meer dan de helft van de mensen met reumatoïde artritis is 6 maanden na de start van de behandeling klachtenvrij. 

 

7-punten voedingsprofiel in de keuken

Afbeelding

Aan de tabel "voedingswaarden per 100 GRAM / PER 100 ML / PER PERSOON" is NIET te zien hoe gezond een maaltijd of dieet is.
Dat is ALLEEN te zien wanneer deze voedingswaarden PER 100 GRAM / PER 100 ML / PER PERSOON en de GEGETEN PORTIES ingevuld worden in de 7-punten voedingsprofiel app.

Het 7-punten voedingsprofiel laat in één oogopslag zien hoe gezond of ongezond een maalhttps://elmondo.org/havermoutpap-toast-met-zachtgekookte-eieren-en-volkorenpasta-met-tonijntijd of dieet is.

7-punten voedingsprofiel van een gezonde maaltijd ziet als volgt uit:

  1. maximaal 35 En% vet
  2. maximaal 10 En% verzadigd vet
  3. maximaal 70 En% koolhydraten
  4. maximaal 25 En% suikers
  5. minimaal 1.3 gram vezels per 100 kcal
  6. maximaal 35 En% eiwit
  7. maximaal 0.3 gram zout per 100 kcal

Maximaal 35 En% vet wil zeggen, dat het aantal gram vet maximaal 35% bijdraagt aan het totale caloriegehalte (kcal) van het desbetreffende product/de maaltijd/dieet. In een 2000 kcal-dieet komt dit overeen met 77.8 gram vet (77.8X9 kcal = 700.2 kcal. 700.2 kcal draagt 35% bij aan 2000 kcal).
1 gram vet levert 9 kcal, 1 gram koolhydraten, 1 gram suikes of 1 gram eiwit levert 4 kcal.
0.3 gram zout per 100 kcal komt overeen met 6 gram zout per 2000 kcal-dieet.
1.3 gram vezels per 100 kcal komt overeen met 26 gram vezels per 2000 kcal-dieet.
