A new study tested the psychological benefits of a two-week clinical intervention to increase fruit and vegetable consumption in 171 young adults (aged 18–25).
Participants were randomly assigned into
a diet-as-usual control condition,
an ecological momentary intervention (EMI) condition involving text message reminders to increase their consumption plus a voucher to purchase fruits and vegetables,
or a fruit and vegetable intervention (FVI) condition in which participants were given two additional daily servings of fresh fruits and vegetables to consume on top of their normal diet.
Only participants in the last group (FVI) condition showed improvements to their psychological well-being with increases in vitality, flourishing, and motivation relative to the other groups. No changes were found for depressive symptoms, anxiety, or mood.
Giving young adults fresh fruit and vegetables to eat can have psychological benefits even over a brief period of time.
Archaea and bacteria (eubacteria) are single-celled organisms that do not have a nucleus or organelles. Archaea have a distinct evolutionary history and biochemistry compared with bacteria.
Archaea - a domain of single-celled microorganisms. These microbes are prokaryotes. Archaea can survive in extreme and harsh environments like hot springs, salt lakes, marshlands, oceans, gut of ruminants and humans.
Bacteria - a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Eubacteria are ubiquitous and are found in soil, hot springs, radioactive waste water, Earth's crust, organic matter, bodies of plants and animals, etc.
