What are the nutrients a marathon runner needs and what do they do?

Carbohydrate
Provides the superior fuel source for muscles during physical exercise.
Carbohydrate is stored in limited amounts only and needs to be
continually replenished. To learn more about carbohydrate and
carbo-loading click here

Fibre
Helps keep bowels regular and can help reduce blood cholesterol.
Marathon runners may need to decrease fibre pre-competition to prevent
gut problems.

Protein
Essential in the growth and repair of all body tissues, including muscle
and bone; hormone and enzyme production; optimal immune function.
Protein is also a minor source of energy. To learn more about protein click here

Fat
Provides the most concentrated and largest source of energy. Fat
provides most of the energy for daily activity. Required for normal
growth and healthy skin, production of certain hormones, structural
component of body cells, supply of fat-soluble vitamins A, D, E and K.

Water
Prevents dehydration, helps cool the body and acts as a transport
medium. Stored in the body in limited amounts. To read more about water,

Vitamin B Complex
Involved in carbohydrate, protein and fat metabolism. B12 and folate are required for red blood cell production.

Vitamin C
Enhances iron
absorption, acts as an antioxidant (antioxidants ?mop up? free
radicals, preventing cell damage), increases energy production, is
necessary for the synthesis of collagen for the formation of connective
tissue and bone.

Vitamin E
An antioxidant that helps prevent cell damage caused by free radicals.
Free radicals are substances that cause cell damage. As a result of
greater oxygen uptake athletes have higher levels of free radicals.
Antioxidants ?mop up? free radicals, preventing cell damage.

Minerals

Iron
Required for the formation of haemoglobin and myoglobin, the
oxygen-carrying components of red blood cells and muscle cells
respectively. Required for energy reactions to take place. To learn more

Calcium
Required to build and maintain strong bones and teeth, essential for

  • Vegetables and fruits (recommended serves ? 2 fruit & 3 vege)

serves you had from each food group and compare with the recommended
serves.

answer! Often when marathon runners reach for supplements they choose
supplements that are not appropriate for their needs anyway. Marathon
runners sometimes forget that the goodness they try to get from
supplements has been scientifically proven to be of most benefit when
found in its natural form in food.

Write down one goal that you will work on over the next week to
improve your baseline nutrition. For example: ?My goal this week is to
increase my daily servings of vegetables from one to three.?

Write down your ideas for a meal plan that will enable to you meet your nutritional goals.
