I'm the Dauphin in France

Chapter 1399 Wisdom of the 19th Century

"That's roughly it," Joseph added at the end. "Blood pressure is directly related to diseases such as heart disease and stroke, and high blood pressure must be addressed promptly..."

Doctors and biologists alike were astonished; it was the first time they had ever heard of pressure issues in the human body during blood transport, and that these issues were so closely related to health.

Joseph looked at everyone and said, “We can measure blood pressure by compressing an artery—when an artery stops beating under pressure, it means the blood pressure is below that pressure value.”

"The pressure is then gradually reduced, and the pressure value at the moment the artery starts pulsating again is the blood pressure..."

He only had a superficial understanding of blood pressure measurement and could only describe what a blood pressure monitor looked like from memory.

"Use a hollow air cushion to hold your arm in place, then inflate it to increase pressure. As for how to measure the pressure... it should be with a mercury column..."

"Who is willing to undertake the development of this instrument?"

The meeting room was completely silent. The main problem was that the Crown Prince had only given a general idea, leaving everyone completely at a loss for how to proceed.

Just as Joseph frowned and was about to appoint a few people to develop a blood pressure monitor, Dr. Bisha stood up and said, "Your Highness, if we only need to determine whether a patient's blood pressure is higher than that of an average person, perhaps we don't need a sophisticated machine."

"So how do you plan to measure it?"

“I think there is someone who can do it,” Dr. Bisha said. “Mr. Joel Prevost.”

"Is he... a doctor?"

“Mr. Prevost is a court magician, Your Highness.” Seeing the Crown Prince frown, Bisha quickly explained, “He has the most sensitive hands in the world, and it is said that he can tell whether there are 5 hairs or 7 hairs on his hands.”

"My idea is to have him hold the patient's arm with his hand and then gradually relax. Then, use a stethoscope to listen to the patient's pulse, and when the artery starts to beat, have Mr. Prevost remember how much force was used at that moment."

"Then, the same steps are repeated on normal people. By comparing the difference in the force applied to the arteries of the two individuals, Mr. Prevost can determine whether the patient's blood pressure is too high."

Joseph nodded. Although the method was extremely rudimentary, it might actually be possible to detect high blood pressure by touch.

Before the invention of the blood pressure monitor, it was a makeshift solution.

"Okay, why don't you go and find him and give it a try?"

"Yes, Your Highness."

Joseph looked at the group of doctors again: "Is there anyone familiar with mechanics or pressure science? I'll have the engineering design institute send their best technicians to assist you in developing the blood pressure monitor..."

The following day at noon.

In the dining room of the Petit Trianon, Queen Mary looked at the pan-fried veal steaks, grilled fish, and pigeon soup in front of her with a worried expression, and couldn't help but sigh.

Although these were all delicacies carefully prepared by the imperial chefs, she had absolutely no appetite for them.

All she wants right now is a big slice of strawberry cake, or even a "polite lion" would be fine with her.

Yes, she hadn't had dessert for two days in a row, which made her feel like the whole world had turned gray, as if even God had abandoned her.

Louis XVI said gently from the side, “My dear, this salmon is grilled very well, you must try it… You didn’t eat much for breakfast, your body won’t be able to take it if you continue like this.”

He hasn't even gone to the workshop these past two days; he's been taking care of his sick wife.

Queen Mary sighed again and listlessly picked up her fork.

Just then, Countess de Berninac knocked lightly on the door and said, "Your Majesty, His Highness the Crown Prince has arrived."

Joseph entered the restaurant, quickly bowed to his parents, and then gestured behind him, saying, "Please bring it in."

Immediately, several servants came over and placed three plates on the large dining table. Joseph personally opened the lid of the first plate, and Queen Mary's eyes lit up—it was a beautifully designed strawberry cake!
But then, she almost burst into tears, and whispered, "Darling, what are you going to do with it?"

Two days ago, Joseph and the royal physician solemnly told her that she must never eat sugar, honey, bread, or even potatoes again.

Joseph picked up the second lid: "This is for your dessert, of course."

"Dr. Kobisa said I can't eat these..."

Joseph pointed to the bright orange pudding on the plate and smiled, "This is something I specially asked Mr. Karem to prepare for you."

"They don't use any cane sugar, but rather fructose made from apples and strawberries."

"What's the difference?"

"Fructose has almost no effect on blood sugar." Joseph sighed inwardly. Fortunately, he had heard his homeroom teacher mention in his previous life that fructose absorption does not require insulin, so diabetics can eat it.

As he spoke, he picked up the last lid, revealing a "courtesy lion" on the plate: "As for these pastries and cakes, they are made with almond flour, walnut flour, a small amount of wheat flour and rye flour. Although they will still raise blood sugar a little, as long as you don't eat too much, the impact won't be too great."

He has already assigned several chemists and biologists to search for sugar substitutes similar to xylitol, but he estimates that there is little chance of a breakthrough in the short term. So he has put a lot of effort into preparing these desserts for his mother that have the lowest glycemic index that he can think of.

Queen Mary rose with joy and embraced her son: "My dear, you are simply God's savior!"

Joseph patted her back and gestured to the table: "Try it."

Queen Mary nodded, returned to her seat, carefully cut a small piece of strawberry cake, and then hesitated, "Really, is it alright?"

"Don't worry, just don't eat too much."

Queen Mary immediately put the cake in her mouth and chewed it carefully. The sweet taste instantly filled her mouth, making her squint her eyes in happiness.

To be honest, the taste is not as good as the cakes I used to make, especially the cake itself. It's not as soft as the ones made with regular flour, and it crumbles easily when you chew it.

However, the sweetness was only slightly less. For her, who hadn't had dessert in "a long time," this was already a dreamlike experience.

Half an hour later, Queen Mary finished her lunch.

She ate about a quarter of each dessert, as well as most of a grilled fish and some steak.

Joseph waited for her to finish her post-meal rituals, then stood up and immediately stepped forward with a smile, patting his chest, saying, "Mother, now we are going to 'declare war' on the dessert you ate!"

"what?"

Half an hour later, the King and Queen ran along the cobblestone path of the Little Trianon Palace in the warm sunshine.

Joseph cheered them on loudly from the sidelines: "Come on! You've already run 700 meters, keep going! 300 meters left! Then play tennis for 30 minutes, and your lunch break will be over!"

Yes, another powerful tool in combating diabetes is exercise.

Joseph had heard that vigorous exercise could cause muscles to burn sugar in the blood.

Although Queen Mary had just eaten a "low-sugar dessert," it still contained a small amount of sucrose and starch, which she needed to burn off through exercise.

He estimated that his mother's blood sugar levels should be under control using this method.

As for the father, it would be beneficial for him to exercise as well—his belly now looks like it's covered with three swimming rings, and if he doesn't exercise, he'll probably soon be plagued by high blood pressure, high cholesterol, and high blood sugar.

Joseph didn't expect that just three days later, the Queen's "healthy dessert" would quietly become a sensation at Versailles Palace...
