Ultra-processed foods – like cookies, chips, frozen meals and fast food – may contribute to cognitive decline

  Scientists have known for years that unhealthy diets – particularly those that are high in fat and sugar – may cause detrimental changes to the brain and lead to cognitive impairment.

  Many factors that contribute to cognitive decline are out of a person’s control, such as genetics and socioeconomic factors. But ongoing research increasingly indicates that a poor diet is a risk factor for memory impairments during normal aging and increases the risk of developing Alzheimer’s disease.

  But when evaluating how some diets may erode brain health as we age, research on the effects of consuming minimally processed versus ultra-processed foods has been scant – that is, until now.

Should you avoid meat for good health? How to slice off the facts from the fiction

  More than half of Americans who make New Year’s resolutions resolve to “eat healthier.” If you’re one, you might be confused about the role meat should play in your health.

  It’s no wonder you’re confused. One group of scientists says that reducing red and processed meat is a top priority for your health and the planet’s. Another says these foods pose no problems for health. Some of your friends may say it depends and that grass-fed beef and “nitrite-free” processed meats are fine. At the same time, plant-based meat alternatives are surging in popularity but with uncertain health effects.
