1999年8月，某装修公司经卢某某介绍，认识了某信用社主任何某。9月3日，信用社与装修公司签订了贷款协议，约定：信用社贷款给装修公司15万元，用于购买装修材料；贷款期l年，从1999年9月4日至2000年9月3日；贷款方应按计划发放贷款，否则按违约数额和误期天数支付违约金；贷款利率按营业所现行利率计算，如遇调整，按调整后利率计算。某建筑公司同意为装修公司的借款提供担保，担保方式为动产抵押。合同签订后，装修公司如期到信用社提取贷款时，却发现信用社已将15万元贷款给了中介人卢某某。此后装修公司未再提及此事。

2000年9月7日，信用社在未做任何通知的情况下，直接从建筑公司在该信用社的账户上扣划了15万元及利息。建筑公司认为：信用社没有贷款给装修公司，二者之间没有形成信贷关系，主债务不存在，担保关系也不成立，因此，信用社应当返回其扣划的款项。装修公司认为：信用社没有履行贷款协议，现在履行对其已无必要，要求法院判决解除双方订立的合同。

信用社认为：其与装修公司签订了贷款协议，卢某某是以装修公司的名义取走贷款的，卢的行为代表了装修公司的行为，因此，信用社到期依法扣划担保人的款项是合情合理的。

根据以上情况，回答下列问题：

卢某某和装修公司之间是否存在着代理关系？（）

A、是

B、否

Eating a diet high in processed（经过加工的） food increases the risk of depression（抑郁）, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.

Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants（参与者） into two types of diet--those who ate a diet largely based on whole food，which includes lots of fruit, vegetables and fish，and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat，refined（精制的） grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.

Those who ate the most wholefood（全天然食物） had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods.

Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.（解释原因） He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.

Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.

He added people's diets were becoming increasingly unhealthy. The UK population is consuming （消费）less nutritious, fresh produce and more saturated（饱和） fats and sugars.
