(61 cards)
Focus of naturopathic nutrition?
WIDC
Whole, organic food
Individualised - constitution, lifestyle etc
Detoxification/cleansing
Cause
How junk food is detrimental to health?
RANE
Reduces life expectancy and performance
Addictive habits
(lack of) Nourishment for cells and tissues
Electrical flow between cells is impaired
Why eat grass-fed meat and not grain-fed meat?
Grain-fed - high omega-6 to omega-3 ratio (20:1)
High in inflammatory fatty acid - arachidonic acid
Grass-fed/wild meat omega-6 to omega-3 (2:1)
Higher conjugated linoleic acid (CLA) which regulates health health and blood sugar.
Why organic meat?
Higher levels of vitamins and minerals (incl beta carotene and vit E) and amino acid profile.
Non-organic - possible chemicals, abx and xenoestrogens.
Benefits and negatives of red meat?
Benefits:
Complete protein (ie all 9 essential amino acids)
Good source of vitamins and minerals incl iron and zinc.
Negatives:
High cholesterol and saturated fats.
Dense protein - burden on digestive system & kidneys
Acid-forming
Benefits and negatives of poultry?
Benefits:
Complete protein
High in B vits (although lower in B12 than red)
Iron and zinc
Magnesium
Negatives:
Food poisoning risk
Often intensively farmed, poor welfare standards
Benefits of oily fish?
High in omega-3, vitamin D, iodine, calcium and a complete protein (sardines are highest in omega-3).
Negatives of fish?
Long-living predatory fish may contain mercury, PCBs and dioxins.
Over-fishing
Why should you avoid farmed fish?
Contaminated water - faecal waste, dyes and toxic chemicals (abx)
Lower omega-3 content
More disease
Negatives of crustaceans?
High in cholesterol
Food poisoning is common
Waste feeders
(only eat if a clean water source)
Energetics of animal foods?
Red meat - hot/warm
Poultry - neutral (white meat) warm (dark meat)
Crustaceans - warm
Eggs - neutral
Fish - cool
Shellfish - cool
Dairy - cool and damp forming
Why do organic plants have a higher amount of phytonutrients?
These are chemicals the plants produce themselves as a result of their environment, to protect themselves eg from uv light.
How might a vegan achieve getting all 9 essential amino acids?
By having a variety of beans and legumes, nuts, seeds and grains eg combining beans with grains.
The benefits of plant-based foods?
HIVE
Healthy gut microbiome
Intestinal barrier - microbes feed off plant fibre (SCFAs)
Varied source of vits, minerals, proteins, carbs, fats, phytonutrients, antioxidants
Ethical source of food
Definition of a beta-carotene?
Orange pigment that functions as an antioxidant, and a precursor to vitamin A.
Definition of a flavonoid?
Diverse group of phytonutrients (plant chemicals) found in most fruit and veg. Also responsible for the vivid colours.
Definition of lutein?
A type of carotenoid antioxidant that is particularly supportive for eye and skin health. Abundant in green leafy veg.
Definition of quercetin?
A flavonoid found mostly in red-coloured fruit and veg. It has anti-inflammatory and anti-histamine properties.
What is Indole-3-carbinol (I3C)?
Found in cruciferous veg. It helps support healthy oestrogen metabolism.
What are glucosinolates?
Sulphur containing compounds found in cruciferous veg.
What is lycopene?
Antioxidant abundant in tomatoes. Gives some fruit and veg their red colour. It has anti-cancer properties.
What are anthocyanins?
Type of flavonoid which gives red, purple and blue plants their colour. It is an antioxidant.
What is mucilage?
A thick polysaccharide substance extracted from a plant.
Why are root veg so advantageous?
Plant ‘store rooms’ - high levels of antioxidants, vits A, B and C. And iron. nb. skin often has most nutrients.
Source of energy - similar carb levels to grains.
Gently warming - nourishing, sweet and easy to digest.
Good for people who are energetically cold, tired, depleted.
Orange root veg - esp good for spleen Qi energy.
Blood tonic - good for those low in iron.
