Eat more salt and live longer (especially if you have had a cardiovascular event)






04:00 - Funnel plost - Publication Bias

08:20 - Causation vs Association Studies

09:50 - journal NEJM back in 1972
there is a bit of concern about the low salt diet. You can lower blood pressure okay nobody's disputing that but there's a price to pay, you're going to raise a renin and aldosterone levels  fairly substantially. So while you may lower your blood pressure you may actually put yourself at higher risk have coronary artery disease.

10:39 - Intrasalt Study (the main reason for recent advice to lower salt comsumption)

17:00 - Salt and Mortality.
If you eat less salt, you are more likely to die
As you take a high-salt diet your mortality, goes down
As you take more more salt, cardiovascular disease goes down

20:20 - People with high blood pressure, the people the guideline tells to eat less salt.
 Cardiovascular event rate for people as they take more more salt their cardiovascular  evnt rate goes down and down

23:20 - Journal of the American Medical Association
They took 3,685 people and they followed them for seven point nine year
You had 23 times increase in your cardiac event ray when you take a low-salt diet, it looks pretty bad

25:10 - Another cochran review
there was one group that it looked like urs actually very harmful to follow a low-salt diet back group was the cardiac patients, so the people with heart failure the ones I you all tell to eat a low salt diet, they seem to do much worse, much worse than everybody else

25:30 - Potential Harm From Too Little Salt Intake (The National Academies of Sciences)
Especially for those people with heart failure you want to be very very careful because the low salt diet might be extremely harmful to you okay it's not only not good for you but it might be actually very harmful to you and that everything else was that there was a really enough

Evidence indicates that low sodium intake may lead to risk of adverse health effects among those with mid- to late-stage heart failure who are receiving aggressive treatment for their disease


27:10 - Tradeoffs for low sodium intake
Blood Pressure - 3.85 % Decrease (best-case scenario)
Renin (hormone) + 24.3 % Increase
Aldosterone (hormone) + 24.5 % Increase
Adrenaline (hormone) + 9 % Increase

28:20 - The modern treatment for atherosclerosis
Renin - Renin inhibitors are used to treat hypertension
Aldosterone - spironolactone, ARBs & ACE Inhibitors are used to treat high levels of Aldosterone
Adrenaline - is blocked with Beta Blocker
