#87 – Rick Johnson, M.D.: Fructose—The frequent hyperlink in hypertension, insulin resistance, T2D, & weight problems?

On this episode, Rick Johnson, professor of nephrology on the College of Colorado, explains how his analysis into the causes of blood stress resulted in a change of analysis path to focus extra on how fructose has such profound metabolic results. Rick begins by speaking in regards to the relationship between salt and hypertension, then gives a masterclass into uric acid, after which expertly reveals the mechanisms and pathways by which sugar (particularly fructose) can profoundly impression metabolic well being. From there, he explains how he applies this data to actual life sufferers in addition to touches on a number of the most promising concepts round pharmacotherapy which might be being developed in response to the epidemics of fatty liver, insulin resistance, diabetes, and weight problems. Moreover, Rick offers his tackle synthetic sweeteners in comparison with actual sugar, discusses most cancers’s affinity for fructose, and way more.

  • Extra.

§

The connection between blood stress and fructose that shifted Rick’s skilled focus [4:00]

  • It began with wanting into the reason for hypertension
  • The working concept for years was that the kidney has a defect in its means to excrete salt and in order that you find yourself retaining salt and that results in elevated blood stress
  • Rick then discovered that when you raise uric acid in animals, they developed high blood pressure
  • So what made uric acid go up? ⇒ Sugar, and notably fructose, raised uric acid

“We began finding out fructose and fairly quickly we have been so enthusiastic about what we have been discovering that we simply form of modified our analysis path to focus extra on how fructose has all of its metabolic results.”

 

The connection between salt and blood stress (and the function of sugar) [5:45]

Does salt elevate blood stress?

  • The prevailing thought is that an excessive amount of salt elevates blood stress
  • And the recommendation can be to limit the quantity of salt consumption
  • But it surely isn’t actually the salt quantity that makes a distinction, however the salt focus
  • Once you eat salt, your serum osmolality goes up
  • For those who drink water together with consuming salt, you may keep away from this rise in serum osmolality and keep away from the rise in blood stress
  • Rick’s 2018 study confirmed that consuming water with a salty meal will stop an increase in blood stress

Why it could be higher to have a decrease blood stress?

  • When your blood stress is excessive, you’ve gotten an elevated danger for coronary heart failure and stroke. 
  • As your blood stress will increase, you get a gradual improve in danger
  • However when the blood stress will get round 160 to 180…
