Q

Chlorophyll

Describe three benefits of chlorophyll in clinical application

A
  1. Detoxification: It binds with certain carcinogenic compounds (eg. heterocyclic amines, aflatoxins) and down-regulates phase 1 enzymes in the liver, whilst inducing phase 2 detoxification.
  2. Antioxidant: Decreases oxidative damage and promotes endogenous antioxidant activity.
  3. Anti-inflammatory: Inhibits pro-inflammatory TNF-a gene which can be activated by LPS from intestinal bacterial infections / intestinal permeability.
  4. Energy production support: Rich source of magnesium, which supports ATP production.
  5. Wound healing: Applied topically, chlorophyllin can be used to aid healing.
  6. Deodorant: Chlorophyl tablets can be used to reduce colostomy / ileostomy / incontenence odour.

LPS = lipopolysaccharides

Q

Why is it beneficial to include alkalising foods in the diet, and what plant compound is particularly useful for this?

A

Excess acidity in the body contributes to a range of diseases including cancer, osteoporosis, arthritis and kidney stones unless countered by alkalising foods.
Chlorophyll is ‘alkalising’ due to its high alkaline mineral content.

Q

Outline ONE mechanism by which chlorophyll supports detoxification of carcinogens and toxins.

A
  • Chlorophyll can bind with certain carcinogenic chemicals, e.g. heterocyclic amines found in cooked meat, polycyclic aromatic hydrocarbons (tobacco smoke, grilled / charred meats) and aflatoxins (food-borne toxins produced by certain fungi).
  • Also positively influences detoxification of carcinogens in the liver by down-regulating phase I enzymes and inducing phase II.

Q

List 6 benefits and clinical applications of Seaweed

A
  1. Antioxidant and anti-inflammatory: Fucoxanthin, a carotenoid has powerful antioxidant effects. It also reduces the production of inflammatory proteins such as NF-kB and COX-2
  2. Low thyroid function: The high iodine content is useful for the production of T3 and T4.
    (Bladderwrack seaweed is rich in bioavailable iodine and other minerals and amino acids including tyrosine)
  3. Healthy weight management: An easy way to boost vitamins and minerals while being low in calories. Fibre increases satiety. Fucoxanthin has been shown to upregulate expression of ‘mitochondrial uncoupling protein 1 (UCP1), a key molecule in metabolic thermogenesis — decreasing fat accumulation.
  4. Blood sugar control: Promotes better glycemic control. Enhancing the effects of insulin.
  5. Elevated blood lipids: It is linked to reduced serum triglycerides and improved LDL:HDL ratio. The effects are thought to be due to the gel-forming fibre in seaweed, which can bind cholesterol in the intestinal lumen leading to increased clearance of cholesterol.
  6. Digestion and GIT health: High in fibre; enhances growth of beneficial bacteria (supporting GI tight junctions) and supports bowel elimination. Nourishes inflamed digestive tract; ulcers, constipation, colitis.

Q

List 6 benefits and clinical applications of spirulina

A
  1. Detoxification: Acts as an accumulator (biosorbent) of heavy minerals due to ‘ion-exchange binding’. Can bind with heavy metals including cadmium, arsenic, lead and mercury.
  2. Immune-enhancing: Notable increases in natural killer cell activity and has anti-viral properties.
  3. Anti-inflammatory: Reduces the production of pro-inflammatory cytokines by inhibiting the NF-κB pathway. Phycocyanin in spirulina also has COX-2 inhibiting effects.
  4. Anti-cancer: Phycocyanin (a protein extract from spirulina) has anti-cancer properties. It has anti-inflammatory, antioxidant, immune-boosting and anti-proliferative effects.
  5. Exercise performance: Increases endurance, whilst the high amino acid content supports muscle hypertrophy.
  6. Anti-allergic effects: Particularly in relation to allergic rhinitis where the inhibition of histamine from mast cells has been observed.
  7. Anti-hypertensive: Reduces elevated blood pressure; an effect associated with raised nitric oxide production (→vasodilation), high antioxidant protection and lower inflammation.

Q

What are the energetic qualities of garlic?

A

Hot, dry, pungent, spicy

65
Q

What compound does garlic contain and what happens when garlic is crushed or chopped?

A

Garlic contains the compound alliin.

Crushing or chopping garlic releases the enzyme alliinase which converts alliin into the active compound allicin.

Garlic is also rich in fructans (prebiotic oligosaccharides)

66
Q

Benefits and clinical applications of garlic

A

Immunity: Antimicrobial (anti-fungal / bacterial / parasitic / viral). Garlic increases interferons and macrophages.

Dental infections / oral thrush: Chew peeled clove.

Athletes foot: Rub a crushed garlic clove on area.

Ear infections: Put 2–3 drops of warm garlic oil into affected ear (lay on side) for 10–15 minutes.

Digestive health: Warming properties stimulate the ‘digestive fire’. Supports GIT microbial balance (prebiotic / addresses dysbiosis).

Anti-inflammatory: Inhibits inflammatory enzymes such as COX and LOX. Also inhibits the pro-inflammatory NF-kB.

Cardiovascular health: Antihypertensive effects by increasing levels of the vasodilator nitric oxide; decreases arterial calcification (stiffness). Reduces LDL cholesterol and LDL oxidation, whilst increasing HDL. Also has anti-coagulant properties (by inhibiting platelet aggregation), hence improving blood circulation.

Detoxification and anti-cancer: Inhibits phase I and promotes phase II liver detoxification, whilst also stimulating the synthesis of the antioxidants superoxide dismutase and glutathione peroxidase. It is hence used in liver support protocols. Reduces cancer cell proliferation.

67
Q

What do you need to be aware of with garlic intake (caution)

A

May cause mild GI effects (reflux, bloating, flatulence, diarrhoea).

Intake of garlic should be discontinued 10 days prior to surgery.

Doses of greater than 3 g / day may interact with antiplatelet medication.

68
Q

What are the energetic qualities of ginger?

A

Dry ginger is hot.
Fresh ginger is warming.
Dry.

69
Q

Benefits and clinical applications of ginger

A

Digestive health: The warming properties of ginger stimulate the ‘digestive fire’. It is a pro-kinetic that can be used to support the MMC, which is particularly useful in conditions such as SIBO. Ginger can also be effective in cases of IBD (e.g. as a tea).
*Dry ginger might be too strong for someone with Spleen Qi deficiency (weak digestion), so fresh ginger is generally more applicable for digestive complaints. Note that Spleen Qi deficiency contraindicates very hot spices.

Anti-microbial and anti-inflammatory: Inhibits LOX, COX and TNF-α - effective for inflammatory joint pain (i.e. pain worse in the mornings). It has direct anti-microbial capabilities similar to garlic.

Anti-nausea agent: Associated with its carminative effects. Can be used for travel, pregnancy and cancer-related sickness. Ideally use fresh ginger for nausea (or a very small amount dry); dry ginger should not be used during pregnancy as it is too hot.

Cardiovascular health: Circulatory stimulant and lowers LDLs.

70
Q

What are the energetic qualities of beetroot?

A

Gently warming, sweet
(and hence nourishing).

71
Q

What is the nutritional composition of beetroots?

A

Iron, manganese, magnesium, potassium; vitamins C, B6 and folate; phytochemicals including betalain pigments (which stain beetroot - and urine - red), betaine, zeaxanthin and lutein.

Rich in inorganic nitrates which make nitric oxide available to body tissues.

72
Q

Benefits and clinical applications of beetroot

A

83
Q

Benefits and properties of cranberries

A
  • Urinary antiseptic: Cranberry is used in the prevention and treatment of urinary tract infections (UTIs) including cystitis.
  • The bacteria associated with UTIs (Escherichia coli) often contain fimbriae, which enables their epithelial attachment. Cranberry impedes this attachment.
  • Treatment of Helicobacter pylori: Its anti-adhesive properties are also beneficial in the stomach with H pylori.
  • Cardiovascular health: Can reduce blood pressure and oxidative stress with its high antioxidant profile (e.g. anthocyanins).
84
Q

What would be a practical use for cranberries?

A
  • For general health eat fresh berries (ideally organic). Can be added to smoothies and juices. For specific health outcomes fresh cranberry juice or concentrated cranberry extracts can be used.
  • Juice — 300 to 500 mL / daily (divide into two doses); capsules dried powder 250 to 500 mg daily.
  • Note: Many commercial juices are high in added sugar and should be avoided; these can often worsen UTIs.
85
Q

What do you need to be aware of when consuming cranberries? (caution)

A

Avoid using cranberry above the recommended therapeutic doses if suffering from kidney stones (due to oxalate content).

86
Q

What is the nutritional composition of chia seeds?

A
  • One of the highest known plant sources of omega-3 fatty acids (alpha linolenic acid).
  • Also contains: Fibre, calcium, phosphorus, potassium, zinc, copper, magnesium, iron, manganese; high quality protein and a range of antioxidant plant compounds;
  • Rich in mucilage; swell to about 10 times their size when added to liquid.
87
Q

Benefits and clinical applications of chia seeds (Salvia hispanica)

A
  • Antioxidant and anti-inflammatory: The rich antioxidant profile includes tocopherols and phenolic compounds that reduce oxidative stress. The high omega-3 content can lower inflammation.
  • Blood sugar regulation: Decreases
    postprandial glycaemia and prolongs satiety, which is attributed primarily to the fibre content.
  • Digestive support: High in soluble and insoluble fibre; they increase stool bulk and can be useful in cases of constipation. The mucilage content also soothes the GI mucosa.
  • Cardiovascular health: Reduces LDL and lipid peroxidation.
88
Q

What is the suggested intake of chia seeds?

A

Suggested intake: 15–30 g per day (1–2 tbsp)

89
Q

What do you need to be aware of with chia seeds (caution)

A

Foods high in mucilage may decrease absorption of medications. Take two hours apart.

90
Q

What are the energetic qualities of chia seeds?

A

Cooling, moistening.

91
Q

What are the main compounds of pomegranates (Punica granatum)?

A

Vitamin A, C, K and folate; iron, calcium, potassium, phosphorus, magnesium and zinc.
Phytonutrients include:
- ellagitannins (antioxidant / anti-inflammatory)
- punicic acid (a form of conjugated linolenic acid — antioxidant, anti-inflammatory, lipid-lowering)
- anthocyanidins (antioxidant).

92
Q

Name FOUR benefits and clinical applications of pomegranates

A
  • Digestive health: Ellagitannins inhibit growth of certain pathogenic bacteria while increasing growth of other beneficial bifidobacterium.
    Punicic acid (concentrated in the seed oil) is known to activate PPARs (transcription factors), reducing intestinal inflammation such as that seen with inflammatory bowel diseases.
  • Anti-inflammatory: Pomegranate blocks the activation of inflammatory pathways including the NF-κB pathway.
  • Insulin sensitivity: Associated with an improvement in insulin resistance — thought to be through PPAR activation.
    Can be used in Type II diabetes, polycystic ovarian syndrome etc.
  • Improves cardiovascular health: Can
    reduce systolic and diastolic blood pressure in hypertensive patients (150 mL juice / daily either as a single dose or daily dose over two weeks).
  • The hypotensive effects of pomegranate are considered to relate in part to the antioxidant capacity of phytochemicals in the juice, as well as the nitric oxide forming properties of pomegranate.
  • The high anti-oxidant content of pomegranate protects the endothelium, and also decreases LDL oxidation.
  • Anti-carcinogenic: Several constituents including ellagitannins, anthocyanins and phenols decrease
    expression of cyclooxygenase-2 (COX-2) leading to reduced proliferation of cancer cells as well as decreased inflammation.
  • Shown to inhibit cancer cell growth and induce apoptosis.
  • Effects are far greater using pomegranate juice versus isolated
    constituents, highlighting synergistic effects of other plant compounds including anthocyanins and flavonols.
  • Benefits have been observed in a range of cancers including colon, prostate and breast cancer
93
Q

What do you need to be aware of with pomegranates when taken regularly (caution)

A

Care with regular intake, particularly in larger amounts in those taking warfarin or antihypertensive medications (may decrease medication requirements — monitor blood pressure and consult doctor if necessary). Particular care with ACE-inhibitor drugs as pomegranate may intensify the effects.

94

A

Warm, sweet (nutritive), moist, Yin.

98
Q

Name TWO benefits and clinical applications of maca (Lepidium meyenii)

A
  • Fertility and sexual function: Increases libido, protects against benign prostatic hyperplasia, improves erectile dysfunction, and increases sperm count, motility and semen volume.
  • Maca does not appear to change serum testosterone and oestradiol levels, but can interfere with androgen receptors. The aphrodisiac properties are related to lipids in maca called ‘macamides’.
  • Enhances energy and cognition: Maca can improve mood and cognitive function, which is thought to be through its action on the endocannabinoid system, as well as GABA and choline content.
  • Provides sustained energy can also be associated with its warming energetic properties — useful for sports performance and fatigue.
99
Q

When you buy maca what do you need to pay attention to?
