Why breakfast matters
Research suggests that people who eat
breakfast regularly:
• have a healthier and more balanced
diet 1
• have a higher intake of key vitamins,
minerals and are more likely to reach
the RDAs2
• are less likely to be overweight3
• Have a lower risk of suffering from type
2 diabetes4 and other chronic diseases
including CHD5

What is the nutritional breakdown of a balanced
breakfast?

•FAO/WHO Dietary CHO in human nutrition 1998
Therefore breakfasts need to be rich in carbohydrates
- Important: not all carbohydrates are equal
And globally balanced in other nutrients
It is important people are having a balanced breakfast that contributes between 20% -25% of daily energy and
nutrient intake. For a women, eating 2000 calories a day, this works out as 400 - 500 calories
After a night’s sleep the bodies limited store of carbohydrates is low
The benefits of a breakfast rich in
carbohydrates
• Can have a positive effect on lipid and
carbohydrate metabolism6
• A recent study indicated breakfast may
have a beneficial effect on satiety and
appetite regulation, which could help
control energy intake, potentially by
reducing sensations of hunger during
the morning and reduction in calories
consumed at lunch time7

The metabolic advantages at breakfast time
of carbohydrates which produce a moderate
glycaemic response
• The benefits associated with eating breakfast
depend on the quality of breakfast and the type
of foods consumed
• Experts in nutrition generally agree on the fact
that breakfast should be rich in carbohydrates
and fibres, and balanced in terms of fat intake
• These characteristics help meet daily nutritional
recommendations, as diets in industrialised
countries tends to have a too low carbohydrate
content and too high fat content
7
Not all carbohydrates are the same
• Eating a balanced breakfast, rich in
carbohydrates that resulted in moderate
glycemic response, reduced subsequent
insulin and TG response, compared with a
breakfast rich in carbohydrates, that
produced a high glycemic response.8
• Breakfast containing carbohydrates, which
produced a moderate glycaemic response,
had a more positive effect on satiety when
compared with breakfasts that were high GI
in obese and overweight subjects.9

The beneficial effects of slowly digestible starch
demonstrated with Belvita Breakfast
• Several clinical studies have tested the
metabolic impacts of a breakfast based
on Belvita Breakfast rich in SDS and a
breakfast based on extruded cereals
containing almost no SDS. The
isoenergetic breakfasts were similar in
terms of macronutrients and fibre so
that the only difference related to the
content was the level of SDS of the
cereal food.
• The results showed that Belvita
Breakfast rich in SDS, when consumed
as part of a breakfast, provides a
regular and continuous appearance of
glucose in the blood, resulting in
moderate glycaemic and insulinaemic
responses after meal.

About Belvita Breakfast Belvita Breakfast biscuits are
• Rich in cereals, containing on average
64%
• A source of whole grain
• A source of fibre (at least 3g/100g)
• Quality fats with less than 35% of the
fat made of saturated fatty acids, no
hydrogenated fats, virtually zero TFA
• Contains vitamins and minerals
• Contain high levels SDS
• Portion controlled, convenient, tasty
• When eaten with a portion of fruit, dairy
and a tea or coffee, contributes to a
balanced breakfast
12
What makes Belvita Breakfast different?
• An adapted nutritional profile –
designed to meet nutritional criteria
specifically adapted for breakfast
• Slowly digestible starch released
regularly and continuously throughout
the morning
• A moderate glycaemic and insulinaemic
response after breakfast
13
• Eating a balanced breakfast is a marker for a healthy lifestyle1,2,3,4,5
• It is not only having breakfast that is important but also its nutritional
composition
• Carbohydrates play a key role as part of breakfast, refuelling the
body with energy after the over-night fasting period
• Carbohydrates differ in quality and the manufacturing process has a
crucial influence on the metabolic effects the carbohydrates may
have
• Breakfasts that include cereal food rich in SDS such as Belvita
Breakfast, could be a delicious option for a balanced breakfast
