Eating protein makes your gut release certain hormones that help you feel full faster and eat less food.
Causal
Eating lots of protein makes your body absorb more calcium from food and pee out more calcium, but studies show this extra calcium in pee comes from what you eat, not from your bones getting weaker.
Correlational
Eating lots of protein makes your kidneys work harder in healthy people, but it probably doesn't harm them if your kidneys are already healthy. However, if you have kidney problems, high protein might make them worse.
Eating more protein makes you feel fuller than eating lots of carbs or fats, which can help you eat less and lose weight over time.
Eating a lot of protein might make kidney function get worse faster in people whose kidneys are already working too hard, but it doesn't seem to affect people with normal kidney function.
Eating a lot of protein might make your kidneys get worse faster, according to a big study that followed people over time.
Eating more protein might make your kidneys work worse over time, according to a big study that followed a group of adults.
Eating a lot of protein might make your kidneys work too hard, based on a big study of over 9,000 adults.
Eating more protein is linked to how well your kidneys filter blood, even when considering other health factors like weight and blood pressure.
A study found that eating more salt didn't really change how well the tiny filters in your kidneys work in healthy Japanese adults, even though people who ate more protein also tended to eat more salt.
Scientists counted the tiny filters in healthy Japanese people's kidneys and found there are about 685,000 on average, giving us the first clear picture of how many filters normal human kidneys have.
Descriptive
Scientists measured how fast tiny filters in the kidneys work in healthy people, and it's the first time they've directly checked this in living humans using special scans and tissue samples.
Eating more protein, adjusted for your ideal weight, is linked to better kidney filtering in healthy Japanese adults, even when other health factors are considered.
A study of over 30,000 heart disease patients on statins suggests that aiming for very low cholesterol levels might not be necessary for everyone, even though guidelines recommend it.
For heart disease patients on statin drugs, having very low cholesterol levels doesn't seem to make a big difference in heart problems compared to having slightly higher levels, according to a large study.
People with heart disease who take statin drugs and get their bad cholesterol down to a lower range (70-100) are less likely to have serious heart problems than those with slightly higher cholesterol (100-130).
In heart attack patients, those with the lowest 'bad' cholesterol levels tend to have more inflammation than those with higher 'bad' cholesterol levels.
When people have a certain type of heart attack, those with lower 'bad' cholesterol tend to have lower levels of inflammation in their blood.
When someone has a serious heart attack, having lower 'bad' cholesterol might actually mean there's more inflammation happening in their body, which could be a sign of worse health.
For heart failure patients younger than 70, having lower 'bad' cholesterol might actually be linked to a higher chance of dying.
This claim says that when people with very serious heart problems have higher 'bad' cholesterol levels at the start of treatment, they might actually live longer than those with lower levels.
For people with very bad heart problems, having lower 'bad' cholesterol at the start of treatment might actually lead to a higher chance of dying over 20 years, especially if they're younger than 70 or taking cholesterol-lowering drugs.
The Swank diet keeps saturated fat very low—less than 15 grams a day—no matter how many calories you eat, which matches its own rules and health experts' advice for lowering cholesterol.
This means that the Swank diet is rated almost as healthy as a standard healthy American diet for adults in their 30s to 50s, and both diets are expected to lower the risk of long-term illnesses about the same amount.
