  • Young People Feel Better Being Giveg Fresh Fruits

    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

    1. a diet-as-usual control condition,
    2. an ecological momentary intervention (EMI) condition involving text message reminders to increase their consumption plus a voucher to purchase fruits and vegetables,
    3. 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.

  • Fruit for Lower Blood Pressure and Glucose Levels

    Among Chinese adults, a higher level of fruit consumption was associated with lower blood pressure and blood glucose levels and, largely independent of these and other dietary and nondietary factors, with significantly lower risks of major cardiovascular diseases

  • Declaration on Consciousness

    On July 7, 2012, a prominent international group of scientists - cognitive neuroscientists, neuropharmacologists, neurophysiologists, neuroanatomists and computational neuroscientists - gathered at The University of Cambridge to reassess the neurobiological substrates of conscious experience and related behaviors in human and non-human animals

    The Cambridge Declaration on Consciousness:

    The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness. Nonhuman animals, including all mammals and birds, and many other creatures, including octopuses, also possess these neurological substrates.

  • Fruits and Vegetables against Specific Cancer Types

    Statistically significant protective effect of fruit and vegetable consumption was found in 128 of 156 dietary studies that examined the relationship between fruit and vegetable intake and cancers of the lung, colon, breast, cervix, esophagus, oral cavity, stomach, bladder, pancreas, and ovary.

    For most cancer sites, persons with low fruit and vegetable intake (at least the lower one-fourth of the population) experience about twice the risk of cancer compared with those with high intake, even after control for potentially confounding factors:

    • For lung cancer, significant protection was found in 24 of 25 studies after control for smoking in most instances.
    • Fruits, in particular, were significantly protective in cancers of the esophagus, oral cavity, and larynx, for which 28 of 29 studies were significant.
    • Strong evidence of a protective effect of fruit and vegetable consumption was seen in cancers of the pancreas and stomach (26 of 30 studies), as well as in colorectal and bladder cancers (23 of 38 studies).
    • For cancers of the cervix, ovary, and endometrium, a significant protective effect was shown in 11 of 13 studies, and for breast cancer a protective effect was found to be strong and consistent in a meta analysis.

    It would appear that major public health benefits could be achieved by substantially increasing consumption of these foods.

  • Fruits and Vegetables for Cancer Prevention

    Diets rich in fruit and vegetables have been recommended for preventing cancer. 

    A significant reduction in the risks of cancers of the esophagus, lung, stomach, and colorectum associated with both fruit and vegetables.

    Breast cancer is associated with vegetables but not with fruit. The risk reduction is significant for cancers of thelung andbladder and only forfruit.

    Bladder cancer is associated with fruit but not with vegetables. 

  • Protection with Vegetarian and Vegan Diets

    Vegetarians, those who avoid meat, represent 5% of the US population, and vegans, additionally avoiding dairy and eggs, 2%.

    Vegetarian diets confer protection against

    • cardiovascular diseases,
    • cardiometabolic risk factors,
    • some cancers, 
    • total mortality.

    Compared to lacto-ovo-vegetarian diets, vegan diets seem to offer additional protection for

    • obesity,
    • hypertension,
    • type-2 diabetes, 
    • cardiovascular mortality.

    Males experience greater health benefits than females. 

  • High-Fat Meals May Be Protrombotic

    The high-fat meals (42% of energy from fat) caused, in contrast to the low-fat meals (6% of energy from fat), considerable increases in plasma triglycerides. The five different fat qualities - rapeseed oil, olive oil, sunflower oil, palm oil, or butter - caused similar postprandial increases in plasma triglycerides. These findings indicate that high-fat meals may be prothrombotic, irrespective of their fatty acid composition

  • Fruits Reduce Risk of Lung and Bladder Cancers

    Case-control studies overall support a significant reduction in the risks of cancers of the esophagus, lung, stomach, and colorectum associated with both fruit and vegetables.

    Breast cancer is associated with vegetables but not with fruit.

    Bladder cancer is associated with fruit but not with vegetables.

    The overall relative risk estimates from cohort studies suggest a protective effect of both fruit and vegetables for most cancer sites considered, but the risk reduction is significant only for cancers of the lung and bladder and only for fruit.

  • Vitamin C in Muscles

    The study has shown that skeletal muscle is very sensitive to changes in vitamin C intake, and that the vitamin C content in muscle will fall if intake decreases below optimal levels. This is likely to affect muscle function. Muscle is the largest store of vitamin C in our bodies.

    Professor Margreet Vissers, from the Centre for Free Radical Research:

    Many people think that all fruit and vegetables are equally able to supply vitamin C, but this is not the case. The levels in food vary hugely across the spectrum. We should eat a good range daily, but because many fruit contain only one tenth of a healthy daily vitamin C requirement, we would recommend at least one serve per day of a high-value food like kiwifruit. This will help you easily reach an optimal vitamin C intake, as well as delivering other vital nutrients.

    There is, however, considerable debate regarding the beneficial health effects of vitamin C supplementation. The administration of vitamin C may significantly hamper endurance capacity. Vitamin C supplementation decreases training efficiency because it prevents some cellular adaptations to exercise.

  • Vitamin C Benefits Debate

    Ascorbic acid is essential for collagen, carnitine and neurotransmitters biosynthesis. Most plants and animals synthesize ascorbic acid for their own requirement, butpes and humans can not synthesize it due to lack of an enzyme gulonolactone oxidase

    Though ascorbic acid was discovered in 17th century, the exact role of this vitamin in human biology and health is still a mystery in view of many beneficial claims and controversies.

    Many health benefits have been attributed to ascorbic acid such as antioxidant, anti-atherogenic, anti-carcinogenic, immunomodulator and prevents cold etc. However, lately the health benefits of ascorbic acid has been the subject of debate and controversies:

    • The relation between ascorbic acid and cancer is still a debatable.
    • There is compelling evidence for antioxidant protection of lipids by ascorbic acid both with and without iron co-supplementation.
    • Current evidences suggest that ascorbic acid protects against atherogenesis by inhibiting LDL oxidation.
    • The data on vitamin C and DNA damage are conflicting and inconsistent.

Fungi

fungus is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms. These organisms are classified as a kingdom Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals. Fungi do not use photosynthesis to create energy.
