Learn to break away from fast foods
A new study in the Journal of Exposure Science and Environmental Epidemiology tested fast food to see if it contained 11 potentially harmful chemicals (phthalates and their replacement plasticizers). The chemicals migrate from packaging into the food and are linked to a long list of serious health problems.
Overall, the tested samples of hamburgers, fries, chicken nuggets, chicken burritos and cheese pizza were polluted with 10 of those chemicals. Meats — chicken burritos and cheeseburgers — were the most contaminated. Cheese pizza had the lowest levels of all chemicals that were investigated.
So do yourself and your kids a favor — ditch fast foods pronto and work on limiting the foods you buy that are packaged in plastics. Biomarkers of phthalates exposure are detected in virtually all of the U.S. population.
But you can’t do it alone. Write your government representatives. Let them know that although some phthalates are banned from toys and other products, they’re still used in food packaging.
7 essential amino acids build proteins, protect your brain
A new lab study in Science Advances has identified the specific essential amino acids that protect the brain from neurodegeneration. In fact, in the lab mice, they “robustly rescued” the critters from existing cognitive damage.
Research has long known that lack of healthy protein can contribute to age-related loss of mental agility. But you can make sure your diet supports brain health by including foods that deliver specific AAS, the building blocks of protein.
Your amino acid diet plan: Lysine is found in black beans, quinoa, pumpkin seeds and soy; leucine is in beans, legumes and soy, as well as (low-fat and nonfat) dairy. Phenylalanine is in nuts, fish, beans, soy, poultry and (low-fat and nonfat) diary.
In the lab experiment those three essential AAS were supplemented with other AAS: isoleucine, histidine, valine and tryptophan. They’re found in nuts, peanuts and seeds, whole grains, fish and poultry — and valine is in vegetables and mushrooms. One note: A study in lab mice found that isoleucine seems to cause aging of muscles and liver. It’s found in meat, fish, poultry, eggs, cheese, lentils, nuts and seeds. So, the best idea is elimination of red meats and full fat cheese and dairy, and moderation for the rest — they’re protein-building foods.
