1. This common vitamin was linked to 13% better cognitive scores

   Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary findings suggest vitamin D could be worth studying as a potentially modifiable factor during an early window of cognitive decline.

2. This common vitamin deficiency becomes far more dangerous when paired with belly fat

   A large study of more than 5,500 adults over 50 found a striking combination of risk factors: abdominal obesity paired with vitamin D deficiency was linked to a 123% higher risk of death over six years. Each condition was associated with increased risk on its own, but together they appeared to create a dangerous feedback loop, with belly fat reducing the amount of vitamin D available in the bloodstream while low vitamin D may worsen inflammation and other health problems.

3. Vitamin C may fight cancer — but not the way scientists once thought

   Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more like an experimental cancer drug than an ordinary supplement. Early studies suggest it may damage vulnerable cancer cells, reduce treatment side effects, and possibly improve outcomes for some patients.

4. Eating one avocado a day may lower heart disease risk

   A daily avocado may help lower heart disease risk in adults with obesity by reducing the number of LDL particles circulating in the blood. After six months, participants who ate an avocado each day experienced a decline associated with an estimated 4% reduction in cardiovascular risk.

5. Scientists may have found a way to prevent statin muscle pain

   Scientists have identified an immune response that may explain why statins cause muscle pain, weakness, and exercise intolerance in some people. The finding could eventually lead to treatments that protect muscles while preserving the drugs’ lifesaving cardiovascular benefits.

6. New microwave frying method could make french fries much healthier

   A new cooking method could make French fries crispier in less time while significantly limiting how much oil they absorb. Researchers propose combining microwave heating, which keeps oil out, with conventional frying, which provides the crunch consumers expect.

7. Mediterranean diet may activate tiny proteins that protect the heart and brain

   The Mediterranean diet may influence aging through tiny proteins produced inside the cell’s mitochondria. Older adults who followed the diet most closely had higher levels of humanin and SHMOOSE, which have been linked to heart and brain protection. Olive oil, fish, legumes, and fewer refined carbohydrates appeared especially important. The findings could eventually help scientists develop more personalized nutrition plans for healthy aging.

8. New calculator reveals whether you should really worry about statin side effects

   Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin medications. Their analysis found that more than 98% of people who qualify for statins are at low risk for these rare complications, despite widespread concerns about side effects. The study also revealed that most eligible patients are not taking statins, potentially missing important protection against heart attacks and strokes.
