Eating more protein while losing weight reduces the rate at which bone is broken down in postmenopausal women, as shown by lower levels of a specific chemical marker in the urine that indicates bone...
When postmenopausal women lose weight by eating fewer calories, eating more protein causes a rise in a hormone called IGF-1, which helps slow down the natural process of bone breakdown and helps...
When postmenopausal women lose weight by eating fewer calories, consuming more protein (about 86 grams per day) instead of the typical amount (about 60 grams per day) helps preserve bone density in...
In middle-aged adults, the increased risk of death from cancer and other causes linked to high protein intake is reduced when the protein comes from plants rather than animals, but this doesn’t prove...
In very old mice, eating very little protein leads to rapid weight loss, while eating more protein helps maintain body weight, suggesting that protein needs increase with age.
In mice, eating less protein lowers a growth-promoting hormone called IGF-1 and raises a protein that blocks it, which slows down the growth of breast and skin tumors.
In middle-aged adults without diabetes, eating a lot of protein is linked to a dramatically higher risk of dying from diabetes, even if they didn’t have diabetes when the study began.
For people over 66, eating more protein—especially from animal sources—is linked to a lower risk of dying from any cause or from cancer, compared to those who eat very little protein.
In people aged 50 to 65, consuming a lot of protein—especially from animal sources—over many years is linked to a substantially higher risk of dying from any cause or from cancer, compared to those...
In mice, eating a diet high in branched-chain amino acids and having chemically induced colitis together caused more severe tissue damage in the colon than either the diet or the chemical trigger...
In mice with chemically induced colitis, a diet high in branched-chain amino acids led to more severe symptoms—greater weight loss, looser stools, and more bleeding—than a standard diet.
In mice, consuming extra branched-chain amino acids increases activity of the mTOR pathway in the colon, even without inflammation, indicating these amino acids directly stimulate a cellular growth...
In mice, consuming extra branched-chain amino acids reduces the levels of proteins involved in cellular cleanup processes in the colon, even without inflammation, indicating these amino acids may...
In mice, a diet high in branched-chain amino acids led to higher activity of the mTOR pathway and lower levels of autophagy markers in the colon, which coincided with more severe intestinal...
Even when all families ate the same fresh food, some households still had higher BPA levels than others, indicating that BPA exposure comes from sources inside the home, like dust or plastic items,...
Only the phthalate linked to plastic food packaging (DEHP) dropped significantly when people avoided packaged food; other phthalates in personal care products or cosmetics didn’t change, showing that...
While BPA levels quickly returned to normal after eating packaged food again, DEHP levels stayed low, indicating that these two chemicals may come from different sources or leave the body at...
When people returned to their normal diet after eating only fresh food for three days, BPA levels in their urine quickly rose back to where they started, showing that exposure to this chemical...
Switching to fresh, unpackaged foods for just three days lowered levels of two common chemicals—BPA and DEHP—in the urine of participants by more than half, indicating that food packaging is a major...
Even after accounting for differences in age, income, smoking, and other factors, people who ate canned food still had higher BPA levels, meaning the connection is likely due to the food packaging...
Children who ate canned food had a much larger increase in BPA in their urine than adults who ate the same amount, possibly because they weigh less or absorb more of the chemical per pound of body...
Drinking from cans did not lead to higher BPA levels in urine, suggesting that the lining in beverage cans may not release as much of this chemical as the lining in cans holding solid foods like soup...
People who ate canned soup had more than double the BPA in their urine compared to those who didn't, and those who ate canned pasta or vegetables/fruit had 70% and 41% more, showing that some canned...
People who ate canned food in the last day had 24% more BPA in their urine than those who didn't, and those who ate two or more canned items had 54% more, indicating that canned foods may be a...
