Food questionnaires are fake science: let us look at spoons
All is for water
tea spoon UK = 3,5516328125 g no more no less
tea spoon US = 4,92892161458 g more precise
coffee spoon Fr = 5 g
You understand why I am not going through the details of the different cups bowls and other subtle differences of our culinary ware...
But I don't resist to quote the WHO:
"4 MARCH 2015 ¦ GENEVA - A new WHO guideline recommends adults and children reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (6 teaspoons) per day would provide additional health benefits."
We are in a mess.

Saturated Fat and Heart Disease
1/ There is no reduction of CHD with low fat diets it's a myth. The problem is that this myth was endorsed all over the planet because "american researchers had proved it"...
2/ When LF diets are not compensated by an increase in CH, LF diet is a low caloric diet and consequently it does produce a reduction in CHD because weight does not increase nor waist and insulin too.
3/ When LF diet is compensated by a high refined CH diet it is worse because this diet produce by transformation in the liver small dense LDL particles which are more atherogenic than large buoyant ones.
4/ Statins do have pleiotropic effects. They lower LDL cholesterol which means that statins reduce the number of LDL particles which are circulating in the blood. If these particles are atherogenic (small dense LDL and VLDL) statins will reduce LDL accumulation in plaques and consequently the rate of coronary or cerebral ischemic events. But statins are also anti-inflammatory drugs which means that statins reduce humoral and cellular response to oxidized lipids in the plaque. This could reduce the rate of plaque rupture and ischemic events.
So the main goal of a preventative program about cardiovascular diseases is to stop smoking. Then increase physical activity on a daily basis id est stop sitting and then decrease the amount of calorie especially CH, especially refined CH and suppress or slash added sugars.
It is not a new fancy program it is the state of the art of human nutrition. But it is very difficult to move on agencies, governments physicians and people...

Le plus grand hoax concernant l'alimentation est lié à l'incroyable stupidité des slogans officiels
Chaque jour on peut se rendre compte de l'inefficacité des slogans officiels concernant l'alimentation.
Faire trois repas par jour toute sa vie la jamais été évalué.
Manger équilibré n'a aucun sens.
Manger X fruits et légumes par jour est une standardisation inadaptée aux besoins et aux individus.
Eviter les aliments gras salés sucrés.
Ce dernier slogan est probablement le plus confus. Que signifie éviter ? Que signifie aliments ? On comprend bien que s'il s'agit de produits industriels gras et que ce gras est représentée par des graisses partiellement hydrogénées ce n'est plus éviter qu'il faut c'est ne jamais à manger. En revanche un morceau de jambon cru bardé de 2 cm de graisse n'est pas à éviter, c'est un excellent aliment.
Il est impossible en suivant ces slogans d'avoir une alimentation adaptée. C'est-à-dire une alimentation faite d'aliments entiers peu transformés ingérés de manière modérée.
