People with mild high blood pressure who ate within an 8-hour window were slightly more likely to feel hungry at night compared to those who only followed the DASH diet.
Descriptive
People with mild high blood pressure who ate within an 8-hour window while following the DASH diet lost about 1.3 kilograms of body fat over six weeks, while those who only followed the DASH diet didn't lose fat.
Quantitative
People with mild high blood pressure who ate within an 8-hour window while following the DASH diet saw their BMI drop by 1.3 points over six weeks, while those who only followed the DASH diet didn't see a change.
People with mild high blood pressure who ate within an 8-hour window while following the DASH diet lost about 4 kilograms over six weeks, while those who only followed the DASH diet didn't lose weight.
People with mild high blood pressure who excreted more salt in their urine while following the DASH diet and eating within an 8-hour window also had bigger drops in their blood pressure.
Correlational
When people with mild high blood pressure followed the DASH diet and ate within an 8-hour window, those who lost more fluid around their cells also had bigger drops in their blood pressure.
People with mild high blood pressure who ate within an 8-hour window excreted more salt in their urine compared to those who only followed the DASH diet.
People with mild high blood pressure who followed the DASH diet and ate within an 8-hour window lost fluid around their cells, but the fluid inside their cells stayed the same.
People with mild high blood pressure who ate within an 8-hour window saw their nighttime blood pressure drop more significantly compared to daytime levels after six weeks.
For people with mild high blood pressure, eating all meals within an 8-hour window while following the DASH diet lowers blood pressure more than just the DASH diet alone over six weeks.
Causal
Eating meals with different potassium levels doesn't change the size of the radial artery or how much blood flow increases after a temporary blockage in people with controlled high blood pressure.
One hour after eating a high-potassium meal, people with controlled high blood pressure have higher blood fat levels compared to a low-potassium meal, which is a statistically significant difference.
One hour after eating a low-potassium meal, people with controlled high blood pressure have higher blood sugar levels than after a high-potassium meal, which is a statistically significant difference.
Two hours after eating a high-potassium meal, people with controlled high blood pressure have slightly higher diastolic blood pressure compared to a low-potassium meal, though the difference is small.
After eating a high-potassium meal, people with controlled high blood pressure may have slightly better blood vessel relaxation two hours later, but this difference isn't strong enough to be considered statistically significant.
When people with controlled high blood pressure eat a meal high in potassium, their blood potassium levels go up significantly compared to a low-potassium meal, especially within an hour and two hours after eating.
For people with controlled high blood pressure, eating a meal with lots of potassium doesn't change how well their blood vessels relax at the start of the meal compared to a meal with less potassium.
When mice eat a lot of salt, adding a moderate amount of potassium lowers their blood pressure, showing that potassium's main benefit might be fighting high blood pressure caused by salt.
In mice eating normal salt, even though extra potassium slows down one salt-handling channel (NCC), it doesn't lower blood pressure because another channel (ENaC) starts pulling in more salt instead.
In mice, when aldosterone hits about 2701 pg/24h (a bit more than normal), the kidney's ENaC channels jump to their highest activity level.
When mice eat a lot of salt, their kidney's salt-handling channels (NCC and ENaC) are already low, and adding more potassium doesn't make ENaC any higher.
When mice eat more potassium on normal salt, their kidney's salt-handling channels change: one type (NCC) slows down but another (ENaC) speeds up, especially when aldosterone hits about 2701 pg/24h.
Mechanistic
In mice, more potassium leads to more aldosterone in a straight-line way, but blood pressure rises sharply only when aldosterone hits a certain level (around 4040 pg/24h), then levels off.
When mice eat a lot of salt, adding a moderate amount of potassium lowers their blood pressure by about 3.6 mmHg compared to eating the same high salt without extra potassium.
