On Friday's "Mad Money," Jim Cramer said that companies such as Heinz ( HNZ), Coca-Cola ( KO) and McDonald's ( MCD) are benefiting as the dollar weakens.

Cramer said he's comforted by signs of inflation, which indicate that some companies will prosper. Fed Chairman Ben Bernanke's efforts to weaken the U.S. dollar in order to re-inflate the economy should especially benefit companies that do most of their business overseas.

Cramer also recommended Eldorado Mines ( EGO) and BP ( BP), which he owns for his charitable trust, Action Alerts PLUS , as weak-dollar plays.

On Monday, Heinz closed up $1.50, or 4.5%, at $34.58; McDonald's closed up $1.96, or 3.7%, at $55.16; and Coca-Cola traded up $1.50, or 3.5%, to close at $44.14. Eldorado was up 38 cents, or 4.7%, at $8.55; and BP closed up $2.50, or 6.4%, at $41.90.

In his "Lightning Round" segment , he was bullish on Taiwan Semiconductor ( TSM), which closed up 76 cents, or 8.9%, at $9.28 on Monday; and Xilinx ( XLNX), which rose 96 cents, or 5%, to a Monday close of $20.26.

He was bearish on Dr Pepper Snapple ( DPS), preferring Hershey ( HSY). DPS rose 27 cents, or 1.8%, to close at $15.40 on Monday, and Hershey was up $1.29, or 3.7%, at $36.22. He was also bearish on TCF Financial ( TCB), even though he said it was one of his favorite financials. On Monday, TCF closed up $1.56, or 13.5%, at $13.15.
At the time of publication, Cramer was long BP.
