Detailed Description
A total of 30 healthy adults (17 males and 13 females) ranging from 19 to 32 years old (mean age 25 ± 1), with a body mass index (BMI) ranging from 19.2 to 28.5 (mean BMI 23.3 ± 0.5) (normal to moderately overweight) participated in this study. To avoid the risk of reaching false conclusions, psychometric validations of food restrictions were determined for all subjects using the revised version of the Three Factor Eating Questionnaire.
This study was carried out according to EFSA requirements [Blundell et al., 2010]. The subjects were instructed to refrain from alcohol and/or from performing difficult physical activities 48 h prior to each test day. The evening before the test day, the subjects consumed a standardised dinner supplied by the study team. The meal consisted of pizza and pineapple juice (800 kcal: protein 18%E, fat 22%E and carbohydrate 60%E). The subjects were instructed to not eat or drink anything other than half a litre of water after the dinner.
After 20 min of resting, on the first day of intervention, anthropometric measurements (weight, height and waist circumference) were collected on subjects wearing only underwear and after emptying their bladder. On each day of the study, a fasting blood sample was acquired after the resting time, and appetites were assessed with a visual analogue scale (VAS).
The subjects were instructed to consume the tested breakfast (the soft roll bread or the control bread plus jam and margarine) within 10 min and were allowed to drink 150 ml of water. The subjects immediately completed two VASs, one on meal palatability and another on appetite feelings. In addition, the appetite feeling VAS was repeated every 30 min until a total of 4 h had passed.
The subjects were not allowed to eat or drink anything else during the 4 h of the intervention. They were allowed to read, study, talk or listen to quiet music, but they were not allowed to sleep. After the last blood extraction (4 h), an ad libitum lunch consisting of a standardised spaghetti Bolognese (17%E protein, 34%E fat and 49%E carbohydrate) and water (300 ml) was provided. The subjects were instructed to eat until comfortably satisfied. Food intake was registered by differences in spaghetti weight before and after lunch, and the energy intake was calculated afterwards. After the ad libitum lunch, the subjects completed two VASs, one on meal palatability and another on appetite feelings. The participants completed a 48-h dietary survey diary, including the food intake during the day before and the day of the intervention.

Intervention / Treatment |
---|---|
Experimental: Puravita Breakfast
Puravita Breakfast is a high protein and high fiber soft bread that contains 22% fruit (figs, apricots, raisins and prunes), a selection of cereals: wheat, oat and spelt and no added sugar.
|
The study was done in duplicate i.e two different days each meal (control and experimental) separated at least one week in time.
Subjects were instructed to consume the test meal within 10 min from commencement.
They subsequently completed VAS on appetite sensation every 30 min until a total of 4 hours.
At the end of the test day, an ad libitum lunch consisting of a standardized pizza (17E% protein, 34E% fat and 49E% carbohydrate) and water (300 ml) was served.
The subjects were instructed to eat until comfortably satisfied.
Food intake was registered and energy intake (EI) calculated afterwards.
|
Placebo Comparator: Control breakfast
White bread (85g) with jam (10g) and margarine (2g) adjusted for energy, fat, and sugar levels and for energy density.
|
The control breakfast consisted of white bread (85 g), jam (10 g) and margarine (2 g) to adjust for energy density, fat and sugar levels.

MEASUREMENT OF POSTPRANDIAL APPETITE RATINGS CHANGES
Time Frame: 0, 30, 60, 90, 120, 180, 210 and 240 min after intervention
|
The behavioural markers of appetite satiation and satiety can be estimated by using two categories of behavioural parameters: subjective sensations and food consumption:
|
0, 30, 60, 90, 120, 180, 210 and 240 min after intervention

Determination of postprandial glycaemia, insulinaemmia and physiological markers of satiation and satiety

Plasma glucose was determined spectrophotometrically (Ref. 1001191Spinreact) Incretins and insulin were determined with the Human Gut Hormone Panel (HMAG-34-04), which include ghrelin, GLP-1 and PYY, together with insulin. For the determination of gut hormones, 2 ml of whole blood will be added Pefabloc SC (AEBSF) (Ref 11 585 916 001, Roche), needed for ghrelin determination (final concentration 1 mg/ml of whole blood) and dipeptidil dipeptidase IV (DPPIV) inhibitor (Ref. DPP-4-010, Linco), needed for the determination of GLP-1 (final concentration of 50 µM). CCK was determined by using EIA Cat. No. EK-069-04, Phoenix Pharmaceuticals, Inc.,) after extraction from 1 ml of plasma |
