Superfoods Flashcards
(182 cards)
What are superfoods?
Foods containing all vitamins, minerals and trace minerals (e.g. algae, sprouts, bee pollen)
How can you refer to the antioxidant capacity of a food?
Oxygen Radical Absorbance Capacity (ORAC) score
What is the ORAC score?
A laboratory test aiming to quantify the total antioxidant capacity (TAC) of a food
Are superfoods always the best choice?
No : local, seasonal produce (ideally organic) is preferable to exotic imports of superfoods
Describe chlorophyll
A thing many super foods have in common : plants use it to trap light and produce ATP in the photosynthesis process
What are the energetics of chlorophyll
Cooling, calming for Yang excess
What are sources of chlorophyll?
Dark leafy green veggies (spinach, parsley, rocket) -> gives plants and algae their green colour
What is the composition of chlorophyll?
The basic structure of chlorophyll is similar to haemoglobin : with a PORPHYRIN ring, but the central atom is magnesium instead of iron
What is a porphyrin ring?
A type of organic compound that binds to metal ions
What is chlorophyll a good source of?
Vit. A, C, E, K, magnesium, calcium, potassium
Benefits and clinical application of chlorophyll
- Detoxification
- Antioxidant
- Reduces inflammation
- Supports energy production
- Promotes wound healing
- Deodorant properties
- Alkalising thanks to high alkaline mineral content
How does chlorophyll contribute to detoxification?
- It can bind to certain carcinogenic chemicals (e.g. heterocyclic amines and polycyclic aromatic hydrocarbons)
- Positively influences liver detox of carcinogens by down-regulating phase 1 enzymes and inducing phase 2
How is chlorophyll antioxidant
Decreases oxidative damage by high antioxidant content and promotes endogenous antioxidant activity
How does chlorophyll reduce inflammation
Inhibits the pro-inflammatory TNF-alpha gene -> this gene is activated by lipopolysaccharides (LPS) released from bacteria (from intestinal bacterial infections or intestinal permeability)
How does chlorophyll support energy production
Rich in magnesium, required for ATP production
How does chlorophyll promote wound healing
Applied topically as a cream or ointment
What is the practical use of chlorophyll
Eat chlorophyll rich foods raw or lightly steamed -> overcooking destroys chlorophyll
What are chlorophyll supplements made of?
Usually chlorophyllin = a semi-synthetic mixture of sodium copper salts derived from chlorophyll -> magnesium is replaced with copper during synthesis
Describe seaweed
Macroalgae can be classified into 3 major groups :
1. Red algae = dulse, nori, laver
2. Brown algae = kelp, bladderwrack, Wakame
3. Green algae = sea lettuce, sponge weed
What is the energetics of seaweed?
Cooling, moistens dryness
What is the composition of seaweed
Wide range of vitamins and minerals, particularly iodine, iron and calcium
Nori is a great source of what?
B12, omega-3, amino acids
Benefits and clinical application of seaweed
- Antioxidant and anti-inflammatory
- Low thyroid function
- Healthy weight management
- Blood sugar control
- Elevated blood lipids
- Digestion and GIT health
Why is seaweed antioxidant and anti-inflammatory
FUCOXANTHIN = a carotenoid found in edible brow seaweed (e.g. wakame) -> powerful antioxidant effects
Seaweed reduces the production of inflammatory proteins (e.g. COX-2, NF-kB)
