Attention to detailcan make that vital difference. Diet affects per<strong>for</strong>mance, and the foods that wechoose in training and <strong>com</strong>petition will affect how well we train and play. Everyplayer needs to be aware of their personal nutritional goals and of how they canselect an eating strategy to meet those goals.Every player is different, and there is no single diet that meets the needs of allplayers at all times. Individual needs also change across the season and playersmust be flexible to ac<strong>com</strong>modate this.Diet may have its biggest impact on training. A good diet can help supportconsistent intensive training while limiting the risks of illness or injury. Goodfood choices can also promote adaptations to the training stimulus – this canlead to more improvement <strong>for</strong> the same training load. The right diet is alsoimportant in preparing <strong>for</strong> games and in hastening recovery afterwards.Getting the right amount of energy to stay healthy and to per<strong>for</strong>m well is key.Too much and body fat increases: too little and per<strong>for</strong>mance falls, injuriesincrease, and illness results.Foods rich in protein are important <strong>for</strong> building and repairing muscles, buta varied diet containing everyday foods will generally supply more than enoughprotein. Well-chosen vegetarian diets can easily meet protein needs. Eating asmall amount of protein just after training may help promote adaptations inresponse to the training stimulus.A varied diet that meets energy needs and is based largely on nutrient-richchoices such as vegetables, fruits, beans, legumes, cereals, lean meats, fishand dairy foods should ensure an adequate intake of vitamins and minerals.Excluding any of these food groups means that more careful food choicesmust be made.Maintaining hydration is important <strong>for</strong> per<strong>for</strong>mance.Fluid intake be<strong>for</strong>e, during (where appropriate) and afterexercise is important, especially in hot climates. Whensweat losses are high, foods and drinks consumed mustcontain sufficient water and salt to replace these losses.Players are cautioned against indiscriminate use of dietarysupplements.Carbohydrate supplies the muscles and brain with the fuels they need to meetthe stress of training and <strong>com</strong>petition. Players must be aware of what foodsthey should choose to meet their carbohydrate needs, how much should beeaten, and when these foods should be eaten.

Every player and every team there<strong>for</strong>ehas to strive to achieve the advantage that is necessary towin. Hard work in training and sound tactics are vital,but a well-chosen diet can offer many benefits:• Optimum gains from the training program• Enhanced recovery within and between workouts andevents• Achievement and maintenance of an ideal bodyweight and physique• A reduced risk of injury and illness• Confidence in being well-prepared <strong>for</strong> match play• Consistency in achieving high level per<strong>for</strong>mances inmatches• Enjoyment of food and social eating occasionsDespite these advantages, many players do not meettheir nutrition goals. Common problems and challengesinclude:• Poor knowledge of foods and drinks and inadequatecooking skills• Poor choices when shopping or dining out• Poor or outdated knowledge of sports nutrition• Inadequate finances• Busy lifestyle leading to inadequate time to obtain orconsume appropriate foods• Limited availability of good food and drink choices• Frequent travel• Indiscriminate use of supplements and sports foodswhich eating and drinking well can allow players at alllevels of per<strong>for</strong>mance to achieve the special goals oftheir training and <strong>com</strong>petition programs. It makes nosense to train hard if you ignore the benefits that followfrom good food choices.<strong>Nutrition</strong> <strong>for</strong> Football is based on the conclusions ofthe <strong>FIFA</strong>/F-MARC Consensus Conference on <strong>Nutrition</strong><strong>for</strong> Sport, held in Zurich in September 2005.

Fat is the major energy store in the body,and is an efficient way to store excess energy <strong>for</strong> use intimes of need.A player will per<strong>for</strong>m best when the amount ofbody fat is within his or her individual optimum range.This will vary between individuals, and will also varyacross a player’s career, so there is no single value that isideal and less is not always better. If the body fat storesfall too low, health will suffer. If body fat stores are toohigh, the player will be slowed down by having to carryunnecessary additional weight. Excess body fat is also ahealth risk. It is important, there<strong>for</strong>e that players managetheir food intake and energy output to achieve anoptimum body size and body <strong>com</strong>position.differences in hydration levels and longer term changescan’t distinguish changes in body fat and muscle mass• Monitoring of skinfold fat thicknesses at intervalsthrough the season, especially when undertaken by atrained kinanthropometrist, can provide usefulin<strong>for</strong>mation about changes in body fat stores• Urinary ketones might provide a marker of inadequatecarbohydrate intake• Measurements of changes in muscle strength andendurance provide a useful biomarker of muscledevelopment• Premature fatigue and loss of <strong>for</strong>m may be signs ofnutrition-related problemsStrategies <strong>for</strong> managing energy intake andenergy balance:Players should individually manage their energy stores ofbody fat, carbohydrate (muscle fuel) and protein (musclemass) by managing intake and expenditure of thesenutrients separately. These issues will be discussed inseparate parts of this booklet.Players should follow an eating plan that helpsthem to achieve their specific goals rather than relyingon appetite to guide energy intake. Advice from a sportsnutrition expert is often required to develop this plan.Players should use a number of separate biomarkersto monitor their progress in achieving each oftheir energy-related goals. Monitoring body weight canbe misleading, and the in<strong>for</strong>mation can be misinterpreted.Body weight is not a reliable or accurate indicator ofenergy balance, since day to day changes mostly reflectSpecial concerns about restricting energy intakeMany players reduce their energy intake at times to assistwith the loss of body weight and body fat, but it isharmful to restrict energy intake so much that it interfereswith normal body function. The diet must provideenough energy (calories) to meet the demands of trainingand match play, as well as cost of growth, development,and staying healthy. Eating less than this on a long-termbasis will lead to a loss of per<strong>for</strong>mance and a risk tohealth.Players requiring advice <strong>for</strong> weight loss or fat lossshould seek guidance from a qualified sports nutritionexpert such as a sports dietitian.If a reduction in body fat content is necessary, thisshould be achieved gradually. Players can avoid potentialproblems by taking care to avoid excess weight gain inthe off-season. Careful management of both diet andactivity levels in the off-season and in the pre-season canhelp players to reach their ideal weight and body fatlevel with minimal impact on health or per<strong>for</strong>mance.To avoid irreversible skeletal damage, any femaleplayer with disruption of normal menstrual functionshould be referred without delay to a medical expert <strong>for</strong>investigation.Weight loss supplementsSome players turn to weight loss supplements and “fatburners” to help them achieve their target weight. Thisis to be strongly discouraged. Most of these supplementsdo not work and those that do carry serious health risks.Some herbal weight loss products have been shown tocontain illegal drugs that are not declared on the label.

In somecountries, many everyday foods are <strong>for</strong>tified with calcium(e.g. fruit juice). The best sources of calcium, however,are dairy foods with low fat varieties providing a greatway to meet calcium needs within a smaller energybudget.Each player should aim to include at least 3 servingsof dairy foods in their daily eating plans – e.g. 200 ml oflow fat milk, 30 g cheese or a 200 ml carton of low fatyoghurt.Calcium-<strong>for</strong>tified soy versions of dairy foods arealso suitable – e.g. soy milk, soy yoghurt.An additional one-two daily servings are requiredduring growth spurts in childhood and adolescence, and<strong>for</strong> pregnancy and when breast feeding.Fish eaten with bones (e.g. tinned salmon, sardines)and leafy green vegetables (e.g. broccoli, spinach) providea useful source of additional dietary calcium.IronIron deficiency is a cause of fatigue and reducedper<strong>for</strong>mance.

Onthe field, they all play together and share the same aimsand ambitions, but at home they are likely to have verydifferent eating habits. Even though they all have broadlysimilar nutrition goals, an infinite variety of differentfood <strong>com</strong>binations can be chosen to meet theirnutritional goals. All the essential nutrients can beobtained from normal foods, and variety is a key tomeeting nutrient needs, but many different foods can beinterchanged. Good sources of carbohydrate may bebread, rice, pasta, potato, couscous, or maize porridge.Protein will be provided by many different foods; theobvious foods are meat, fish, eggs and dairy products,but bread, cereals, pasta, lentils, and beans are only afew of the other excellent sources of protein. The fruitsand vegetables that are <strong>com</strong>monly available will differfrom region to region, although many staples orfavourites are exported around the globe. Our eatinghabits are much more international than they once were,and players can enjoy foods from different countries ofthe world.The vegetarian player need not be at any disadvantage.These players, though, must be more aware of the foodchoices that they make. If there are no animal foods inthe diet, then a Vitamin B12 supplement may benecessary.
