Vegaanisen ruokavalion vitamiini- ja kivennäisainehaasteet lyhyesti - PRONUTRITIONIST

Teksti ei siis ole kattava kuvaus vegaanisen ruokavalion terveysvaikutuksista, vaan katsaus suojaravintoaineiden saantiin liittyviin asioihin.

Scientists find humans age dramatically in two bursts – at 44, then 60

The first wave of changes included molecules linked to cardiovascular disease and the ability to metabolise caffeine, alcohol and lipids. The second wave of changes included molecules involved in immune regulation, carbohydrate metabolism and kidney function. Molecules linked to skin and muscle ageing changed at both time points.

World-First Experiment Reveals Why Some People Never Get COVID-19

Where most people mount a rapid immune response against the invading virus in their blood, these volunteers showed a subtle but much faster reaction in their nasal tissues that included the activation of mucosal-associated invariant T (MAIT) cells and a drop in inflammatory white blood cells, which cleared the virus before it set in.

My uneducated guess is that this is mostly an effect of other risky behavior (more prevalent among tattooed people) that they’ve not accounted for, such as alcohol consumption.

Possible association between tattoos and lymphoma revealed

“After taking into account other relevant factors, such as smoking and age, we found that the risk of developing lymphoma was 21 percent higher among those who were tattooed. It is important to remember that lymphoma is a rare disease and that our results apply at the group level. The results now need to be verified and investigated further in other studies and such research is ongoing”, says Christel Nielsen.

Tutkimus: Epoksipinnoitetusta vesiputkistosta liukeni haitallista kemikaalia lämpimään käyttöveteen – kylmässä vedessä kemikaalia ei havaittu - THL

Hyvä yleinen ohje on, että juomiseen ja ruuanlaittoon ei pidä ottaa hanasta lämmintä vettä, vaan kylmäksi juoksutettua vettä. Vettä juoksuttamalla voi pienentää sekä putkistomateriaaleista veteen mahdollisesti liuenneiden kemikaalien että mikrobien, kuten bakteerien ja homeiden, aiheuttamia terveysriskejä[.]
