Change table spacing
edit:
- with use of the
tabularx, text is vertically centered in cells by:
\renewcommand\tabularxcolumn[1]{m{#1}}font size is set to
\footnotesize- for units in cells' contents is used the
siunitxpackage - more vertical space around the cell contents is done by use of the
cellspacepackage for preserving features of the
Xcolumns is used (modified) macro\addparagraphcolumntypes{>{\null}Y}where

One possible solution is to use the array package. Here's my proposed code. Notice I use \tabularnewline so as to avoid confusion with the \\ in each paragraph cell. Also, you repeat \multicolumn a sufficient number of times that it justifies the creation of a \cmulticolumn command (which also includes some formatting parameters). The solution makes use of a nice thing about the array package: it allows one to define a tabular token (z, for example) which displays a paragraph of a given with.
\documentclass{article}
\usepackage{pdfpages}
\usepackage{array}
\newcolumntype{z}[1]{>{\centering}p{#1}}
\begin{document}
\newdimen\mycol
\setlength\mycol{10ex}
\def\cmulticolumn#1#2{%
\multicolumn{#1}{c|}{\parbox{#1\mycol}{\mbox{}\\[1ex]\centering#2\\\mbox{}}}
}
\resizebox{\textwidth}{!}{%
\def\arraystretch{2}
\begin{tabular}{|z{13ex}*{13}{|z{\mycol}}|}
\hline
Study month & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13 \tabularnewline\hline

FFC/SD & \cmulticolumn{5}{High fat, fructose, cholesterol (2\%),\\ fed 2\% of mean BW} & \cmulticolumn{2}{High fat, fructose,\\ cholesterol (1\%),\\ fed 2\% of mean \\ BW (max 1000g)} & \cmulticolumn{6}{Changed to standard diet, \\ fed fixed ration of 500g.}\tabularnewline \hline

\end{tabular}

\end{document}
The following calculates the available width for equal spaced columns so that the resulting tabular is exactly \linewidth wide. The macro doing so is called \equalspacing and takes as arguments an optional first column (specify the widest entry) and the number of columns you need. The resulting column width is stored in \equalspacingwidth. The calculation assumes that there is a vertical rule everywhere and each column has a full \tabcolsep on both sides (so that you don't use @{}). You can then specify the columns with the *{<count>}{<definition>} notation (e.g. *{13}{p{\equalspacingwidth}|} in for 13 columns).
Further a \multiequal{<count>}{<content>} is defined, which is a \multicolumn as wide as <count> columns of width \equalspacingwidth (plus the \tabcolsep and \arrayrulewidth for each of the spanned columns).
With these two macros you can get the following:
\documentclass{article}

inner=3cm, outer=2cm, footskip = 1.5cm]{geometry}

EDIT: To get vertically centred cells, you can use the m specifier instead of p in the definition of \multiequal.
So with the following definition of \multiequal and the same remaining document you get this:
\newcommand\multiequal[2]
{%
\multicolumn{#1}
{%
>{\raggedright\arraybackslash}m{%
\dimexpr
#1\equalspacingwidth

+#1\tabcolsep

-\arrayrulewidth

}|%
}{#2}%
}
