Digestion L5 slide 34 (2 marks)

Question 2

Explain the difference between Louis Pasteur’s and Antoine Bechamp’s
theories of disease (2 marks)

Answer 2

Pasteur: founder of ‘germ’ theory
Germ Theory: Disease occurs from outside of the body i.e. bacteria, viruses, fungi,
cause diseases from outside.
Bechamp: maintained that disease occurs from within the body (changes of the
terrain, opposite to Pasteur).
* “Bacteria and viruses are the ‘after-effects’ rather than the cause of disease”.
* “Most diseases are the result of an acidic, low oxygenated terrain” (environment)
where the
diseased tissue spawns the growth of microorganisms which develop into different
forms.

1/2 marks for each above, must mention ‘germ theory’ and ‘terrain’

Question 4

Describe THREE enzymes involved in carbohydrate digestion.
Explain the function of each? (3 marks)

Answer 4

• Salivary amylase
• Pancreatic amylase
• Brush boarder enzymes
• salivary amylase starts working on the end of the long glucose chains in starches (hence if you chew starch for a long period, you will start to taste sweetness)
• Salivary amylase works well at a fairly neutral pH but is deactivated by stomach acid.
• In the small intestine, the pancreas releases pancreatic amylase which continues carbohydrate digestion but this time into disacharide units.
• The last stage of carbohydrate digestion involves brush border enzymes in the small intestine (lactase, maltase and sucrase).

Chem & BIochem 1; slide 64. (1 mark each) each enzyme mentioned and explain in
terms of function.

Question 5

List TWO nutrients found in squash and TWO therapeutic uses of
squash (2 marks)

Answer 5

acne, eczema – due to vitamin A’s role in skin barrier), cardiovascular health (high
antioxidant content)

Question 9

Compare and contrast fat and water-soluble vitamins with regard to
absorption and storage (2marks)

Answer 9

Fat soluble vitamins are absorbed within the small intestine into lymphatic capillaries
then the blood (1/2 mark) and are readily stored (1/2 mark).
Water soluble vitamins are absorbed in the small intestine directly into the blood (1/2
mark); storage is minimal, and they are easily excreted (1/2 mark).

• Spring is dominated by moisture. *
• Productive cough, runny nose, watering eyes, allergies, hay fever. * (0.5 per
  point max 2 marks)
• Reduce: dairy, high water content fruit and vegetables, gluten, refined sugars
  and carbs. * (0.5 per point max 2 marks)
• Increase: light, crunchy, dry food, whole grains, vegetables, spices. (0.5 per
  point max 2 marks)
• This is an ideal time to detox using the fresh green leaves that emerge in
  early spring such as nettles and cleavers.
• Summer is dominated by heat. *
• Inflammation, prickly heat, sun-burn, irritability. * (at least 2 points to get full mark)
• Reduce: red meat, oily foods, stimulants. * (at least 2 points to get full mark)
• Increase: salads, raw foods, green smoothies, bitter vegetables and
  detoxifying herbs. (0.5 per point max 2 marks)
• In the summer nature provides abundant greens, berries, fruit and veg -
  perfect cooling foods. *
• Although the summer diet should be generally raw and cool, warm teas and
  spices can be used to promote sweating which has a ‘cooling’ effect. (2
  marks)
• Autumn is dominated by dryness.
• Dry skin, joint stiffness, decreased energy, anxiety.
• Reduce: light, dry foods such as biscuits, gas forming legumes, ‘astringent’
  green tea, ‘hot’ spices. (0.5 per point max 2 marks)
• Increase: warm and ‘hearty’ soups, stews, broths, root veg, high water content
  fruit and veg, sweet herbs such as liquorice, herbal teas. (0.5 per point max 2
  marks)
• In Autumn nature provides its harvest of nuts, seeds, grains and root veg.
  Perfect for building energy, weight and warmth in time for winter (2 marks)
• Winter is dominated by cold.
• Poor circulation, weight gain, sleepiness, low mood, seasonal affective
  disorder (SAD). (0.5 per point max 2 marks)
• Reduce: refrigerated & frozen foods, iced drinks, cold, raw food, leafy foods,
  sushi. (0.5 per food max 2 marks)
• Increase: warm cooked, spiced food and drinks to raise temperature,
  digestive power and circulation.
• Winter provides cruciferous vegetables which are warming and help clear
  respiratory mucus.
• Aside from this we should stay warm, rest, relax and enjoy warm and
  luxurious ‘soul’ food and ‘spices’.

Answer 23

Prescription medication: Antibiotics for recurrent cystitis and fluconazole (antifungal) when needed for thrush.
Supplements: None currently but was previously taking Vitamin D from Boots over
winter.
Presenting symptoms: Jasmine has irritable bowel syndrome (IBS). Her stools will
alternate between constipation and diarrhoea particularly during the week before her period. She experiences urgency and flatulence and occasionally has blood and
mucus in her stool. She feels tired a lot of the time and experiences symptoms of
cystitis including burning and stinging which requires her to take antibiotics (about 5
times per year).
Medical history: Recurrent cystitis and some candida (thrush). Was a fairly healthy
child but would get a cold/’flu every year and athletes foot (tinea) over summer. She
had acne in her early teens and gets the occasional spot now, usually due to her
menstrual cycle.
Family history: Mother also suffers with IBS. Father is on medication for cholesterol
and has high blood pressure.
Diet: She likes salty fatty foods like cheese although it makes her feel bloated.
Doesn’t often feel hungry in the morning and frequently skips a proper breakfast.
Has 3 large glasses of water a day, knows she should have more, but she gets
annoyed having to go to the bathroom to urinate when she drinks a lot.
Breakfast: Large glass of store-bought fruit juice. Sometimes a boiled egg on brown
toast. Black coffee with 1 artificial sweetener at 10am
Lunch: Spinach and feta roll, or mushroom quiche and black coffee with 1 artificial
sweetener. Eaten at her desk.
Snacks: Crisps, salt and vinegar or cheese and onion.
Dinner: White rice or mashed potatoes with fish or chicken, steamed vegetables
(cauliflower, carrots, corn) with a white sauce.
Dessert: Two large (250ml) glasses of red wine with cheese – 2 chunks each about
the size of a box of matches.
Lifestyle: Goes to bed at 10pm and gets up at 6:30am, five days per week. Finds it
difficult to fall asleep and might not drift off properly until midnight. She usually plays
online scrabble in bed on her phone or checks social media to relax as she finds
work stressful. She plays tennis twice a week with her partner.
