Question

Jane Clarke,

My daughter is coming up to her finals.She eats reasonably well but less so in term time,as getting out to buy fresh fruit and vegetables is time-consuming.She has recently often had flu.Can you offer guidance on what to eat and drink when under pressure?

Mary King,

She should mainly take in the B vitamins,the group largely responsible for the smooth running of the nervous system,and vitamin C,which experts believe we need in much greater quantities when we are stressed than the usual.

B vitamins are found in many foods but especially pork,bacon,nuts,dairy products,lean meat,fish,eggs and whole grains-so even if your daughter can’t shop regularly,other foods can work in her favor.Tinned oily fish are good,which can help to block production of the enzyme(酶)that makes us feel tense when under pressure.

Fresh produce usually has the highest and best all-round levels of nutrients such as vitamin C,but if your daughter has a freezer she could buy frozen vegetables,which contain good levels.Fresh juice is another good source of vitamin C.

She should avoid caffeine,as it increases the adrenaline(肾上腺素)generated at times of stress; water would be better.Frequent small meals can help concentration.

High-sugar foods such as biscuits and sweets could make people feel excited,and patients often feel the same; better avoid eating them.Pasta,rice or a jacket potato,will help to calm us down.And drinking plenty of water can also help concentration.
