Course Content
This course contains a series of lectures starting with an introduction to the area, its basic vocabulary and scientific methodologies. Then a series of lectures will exemplify food plant bioactive components, shortly touching upon their functionality in the plant but with a main focus on their bioavailability and biochemical transformations, their bioactivities at the physiological, nutritional and biochemical level after consumption, and the scientific methodologies used to investigate such actions. The following lectures and themes for theoretical exercises will be typically covered:

1. Overview of basic concepts in evaluation of bioactivity and functionality, including demands on scientific documentation for health claims and basics of chemical safety evaluation.
2. Overview of plant foods and health. How strong is the evidence for disease prevention and what is known or speculated about mechanisms.
3. Vegetables 1: Crucifers including cabbage, mustards and watercress (glucosinolates; indoles; isothiocyanates; nuclear receptors; cell cycle control)
4. Vegetables 2: Onion, garlic, carrots, asparagus, parsnip tomato, non-crucifer green vegetables (polysulphides, alkyns, carotenoids etc.; phase 1 and 2 enzyme induction, effects on vision, pro-vitamin A).
5. Fruit: Stone fruit, grapes and citrus (flavonols, ascorbate, triterpenes, carotenoids; antioxidation, effects on cholesterol)
6. Berries, grapes (strawberry, blueberry, craneberry, grapes; polyphenols (catechins and anthocyanins), stilbens; anti-inflammation, effects on vessel walls)
7. Cereals, fruit and vegetables (soluble and insoluble fibre, glucans, fructans, pectins, arabinoxylans, cell wall structures; gut health and immunity, cholesterol and fat biokinetics)
8. Legumes and grain (isoflavonoids, lignans; hormone mimetic effects)
9. Spices (ginger, parsley, dill, chives, thyme, rosemary; terpenes, gingerol, furocoumarins)
10. Beverages (coffee, tea, cocoa, cola; caffeine, theobromine, cocaine, kahweol, cafestrol)
11. Botanicals and common herbal extracts (Ginseng, Ginkgo biloba, chamomile, ; ginsenosides, ginkgolides, others)
12. Relationship between special plant components and taste, interactions in taste.

 
Teaching and learning Methods
In each session there will first be lectures in a general subject or on a specific group of plants with examples of potentially active ingredient groups related to one or more commonly reported actions in humans. The selected group(s) of ingredients would represent a typical agonist for a biochemical or physiological effect. Lectures will be followed by theoretical exercises, typically including critical reading of original articles on the days theme followed by plenary discussions or short individual and ad hoc group presentations.
 
Learning Outcome
This course is a required course on the M.Sc. education in Gastronomy and Health, but optional on Human Nutrition, Clinical Nutrition, and Food Science. The course will give examples of specific non-nutritive components in foods and their possible mechanisms of action. The course is the only one in these educations giving a systematic overview of non-nutritive bioactive components. The course will give a critical insight into the meaning of bioactivity and functional components. It also aims to give a more in-depth insight into the health effects of common plant-based foods, beverages and spices.

Knowledge:
- Describing the most common types of bioactive compounds and components in food plants and spices, and their actions in the human body.
- Knowing the most important laboratory methods to evaluate typical health effects of plant foods in human studies
- Knowing the use of the most common experimental designs in the study of plant effects on health or health-related biomarkers
- Referring to the formal scientific demands for placing a health claim on a food product

Abilities:
- Critically assessing methods, results, and conclusions in scientific papers in the area
- Evaluating the contribution of several studies on a plant food product to conclusions on their effects on human health

Competence:
- Working independently and analytically with scientific literature
- Critical oral and written presentation
