Healthy nutrition in a growing and aging population is a global challenge !
Chronic diseases (NCDs)
• 366 mln with diabetes
• 160 mln with osteoporosis
(US, EU and JP)
Aging population
Under-/overnutrition
• 1 bln people hungry
• 1.6 bln people overweight

Nutritional ingredients for health and well-being – opportunities and challenges
Topics to address:
• For micronutrients there are still many untapped opportunities
Example Resveratrol: an anti-aging ingredient which fits in various nutritional benefit areas
Anti-aging Benefits:
The nutrient with most promising calorie restriction
(CR) mimetic properties

resVida supplementation improves metabolic health in obese humans
S. Timmers et al., Cell Metab Vol 14, 2011 Suppl Info
Study features - randomized, double-blind, placebo
controlled study
- subjects: 11 healthy, obese men
- dose: 2 x 75mg resVida per day
resVida reduces risk factors
associated with obesity - reduction of blood pressure
- improvement of blood glucose and insulin
levels
- reduction of liver fat
- reduction of inflammation markers
-resVida induces an endurance
training like effect in skeletal muscle - increase of fat oxidation capacity
- increase of fat storage capacity of muscle
resVida mimicked calorie restriction

• Fruitflow® is the first ingredient with an European Food Safety
Authority Art. 13.5 health claim
“Helps maintain normal platelet aggregation,
which contributes to healthy blood flow”
• Fruitflow® is a breakthrough anti-thrombotic ingredient
• Multiple (8) human trials confirm Fruitflow® reduces platelet aggregation
– No side effects reported
– Works in 97% of subjects
– Starts to work within 1.5 hours
and continues for 12 to 18 hours
– When taken regularly on a once per
day basis, the effect is continuous
Example Fruitflow® - a new ingredient for healthy blood flow
Page 17
Non activated /smooth platelet Activated / spiky platelet Blood clot
• Platelets can become “spiky” i.e. more prone to clotting due to a variety of factors like stress,
overweight, high cholesterol.
• Fruitflow works by keeping blood platelets smooth to avoid aggregation inside blood vessels.
• Fruitflow does not disrupt the rest of the blood clotting process so clotting will still take place
as usual after injury.
•Three major factors in cardiovascular disease: cholesterol, blood pressure and platelet aggregation,
the cause of blood clots.
•Fruitflow® is the only functional food ingredient addressing platelet aggregation
Fruitflow acts on the first stage of the clotting

• Onset of antiplatelet effect seen within 1.5 hours
after ingestion – measured as a significant
difference from baseline platelet function
• Duration of effect variable, but after 18 hours
platelet function returned to baseline in all
subjects tested.
Results
• Randomized, placebo-controlled, single-blinded
study design.
• 23 normal healthy subjects (40-65 y) completed
the study
• Subjects consumed Fruitflow® equivalent to
the total active fraction found in 6 fresh
tomatoes or a control drink
• Blood samples were collected at baseline, 1.5, 3
and 6h.

Benefits of DHA Alone & Cardiovascular Health
• Favorable effects on blood lipid profile – Reduced triglycerides

• Keske et al, abstract 2007
• Kelly et al, AJCN, 7/2007
– Increased HDL (good cholesterol)
– Improved LDL particle size
• Cardiac rhythm – Stabilizes heart rhythm
– Lowers heart rate • Kelly et al, AJCN, 7/2007
• Theobold et al., 2007
• Modest reductions in blood pressure • Kelly et al, AJCN, 7/2007
• Theobold et al., 2007
– Improved arterial compliance
– Anti-thrombotic effects

Evaluate the effects of Life DHA on cognitive outcomes in healthy elderly (>55 yrs.) with a mild memory complaint •Randomized, double-blind, placebo-controlled, parallel, multi-center (19 US sites)
• Oral Dose: 900 mg algal DHA/day or
placebo (corn/soy)
• Study treatment: 6 months
• Sample size: 485 subjects
• Primary Endpoint: cognitive test of memory, attention &
learning
• Secondary Endpoints: cognitive tests of executive
function, Activity of Daily Living (ADL) skills, plasma
phospholipid fatty acid levels, safety and tolerability

Results of MIDAS study
Primary endpoint: Paired Associate Learning test - learning and memory recall test that discriminates well between aging, MCI, AD and is sensitive to early episodic memory changes. (de Jager, 2002;Fowler, 2002; Egerhazi, 2007)

Conclusions of MIDAS study
• First-ever large, randomized and placebo-controlled study
demonstrating the benefits of algal DHA in maintaining and
improving brain health in older adults
• (900mg/d, 6 months) DHA improves learning and memory
recall in age-related cognitive decline, demonstrating a
significant impact on early episodic memory changes
• DHA significantly decreases heart rate in this older population,
demonstrating cardiac benefit
• DHA has an excellent safety profile and is well-tolerated by
this population
A number of prebiotics are available
• Breast milk oligosaccharides represent a large component of
human milk
• Polydextrose – Fructans fruits
• Inulin wheat, banana, onions, garlic, ..
• Fructo-oligosaccharides plants
• Galacto-oligosaccharides milk
• Lactulose milk
• Soy-oligosaccharides
• Xylo-oligosaccharides
• Isomalto-oligosaccharides corn, wheat
• Lactitol
(Journal of the American Dietetic Assosciatio,2008)
• Short chain fatty acids (SCFAs) are
produced by colonic bacterial
degradation of unabsorbed starch and
non-starch polysaccharide (fibre).
Main short chain fatty acids:
Acetate, propionate, butyrate and
lactic acid.
How do they work in the gut?
SCFAs are important anions in the colonic lumen, affecting
both colonocyte morphology and function
