Health Roundup - Food Edition

Is your diet good for your gut bacteria?  Probably not as Adam Rutherford found when he had his tested

...the results? To be honest, pretty crap....“You are near bottom of the class. You’re in the lowest 10% of the population for diversity,”....How many of these beneficial bacteria did I have? Zero.

Diversity is one of the keys to a healthy gut, he explained, the idea being that different microbes perform different tasks, and a diverse workforce brings more skills to the table. We contain, on average, around one thousand different species of bacteria inside our guts. And in total: well, it’s difficult to count, but there are trillions. And they are almost all doing useful work for us.
Fermented foods are especially good for encouraging a healthy microbiome. “People know about live yoghurts, but the next stage up which has five times as many microbes is kefir, a Persian soured milk,” Spector told me. Other fermented foods like miso soup and kimchi (pickled cabbage) are a delicious feast for your internal lodgers.
If that all sounds a bit rich, then garlic, artichokes, bananas and whole grains are also good fibrous fodder.

Drinking beetroot juice has important brain benefits.

Drinking beetroot juice before working out makes older adults’ brains perform more efficiently, a new study by Wake Forest University has found. “It resembles more of a brain of a younger adult than it does an older adult,"
Beets have a high level of dietary nitrate, which is converted to nitrite and then nitric oxide when consumed, Rejeski said. Nitric oxide increases blood flow in the body, and previous studies have shown it can improve exercise performance in people of varying ages. The study found that combining beetroot juice with exercise delivers more oxygen to the brain and strengthens the somatomotor cortex, which processes information from the muscles.

Gluten-free diets may cause serious health problems

including CANCER due to the high levels of toxic metals found in gluten-free foods. Two major studies from the US reveal that those choosing gluten-free foods have twice as much arsenic in their urine as those who eat gluten. They also have 70 per cent more mercury in their blood and worryingly high levels of other metals such as lead and cadmium. Contamination comes mainly from rice flour, which is used as a substitute in products such as bread, spaghetti and cereals.

The NBA’s Secret Obsession with Peanut Butter and Jelly Sandwiches

With little fanfare, PB&Js have become a locker room staple for multiple teams in the league for over a decade. ...
One reason for the PB&Js popularity is that calorie-dense foods that are high in fats, sugars, starches, proteins, and salts trigger both dopamine and serotonin releases in humans. Any food that gives rushes of energy and happiness is an obvious boon to professional athletes, and those same foods also lower the body’s heart rate.
