Insufficient consumption of fruit and vegetables is associated with an increased risk of non-communicable diseases in the population.
This study found convincing evidence for combining order of placement in a buffet and separating the fruits and vegetables, as a means to increase the quantity of self-served fruit and vegetables and decrease consumption of other meal components among male university students.
This study demonstrated that a nudge design consisting of changing the placement of F&V to the beginning of the serving sequence, and presenting the F&V components in separated bowls increases the self-served quantity of F&V and simultaneously decreased the quantity of non-F&V components in the intervention group and total energy intake.
Vitamin B3, Niacin, nicotinic acid, helps to convert food into energy and is essential for healthy skin, blood cells, brain, and nervous system. It is one of 8 B vitamins. It is water-soluble, which means it is not stored in the body. It has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects.
Niacin occurs naturally in food and can also be made by your body from the amino acid tryptophan, with the help of B6.
It is rare for anyone in the developed world to have a Vitamin B3 deficiency; alcoholism is the main cause of it in the US.
