The swelling in your nose or mucus in your nose keeps the air which carries odors from reaching the nerves that detects and registers "smells" to your brain.
This also affects taste. 80% of taste is from the nerves (olfactory bulb) high in the nose; while 20% is from the mouth - sweet, sour, etc. This involves what is called "retro" that is - odor molecules travel through your mouth through the back of your throat and up into the nasal area and up to the olfactory bulb. If your nasal passages high in the nasal area are swollen shut you will not smell nor taste. When the infection or cold starts to subside you find that your sense of smell is now too strong due to the nerves becoming irritated. This will also subside. The nerve ending that smell and taste are renewed about every 40 days.

Why cant you smell cold food from far while you can smell hot food from far?
It is possible to smell food when it is cold. However, it is much easier to smell food when it is hot. The heat gives off thermal energy, which makes it simpler to smell. Because hot food is much simpler to smell, hotter food often tastes better than colder food. If a food smells good to someone, then it often has a better taste, too. Edit: If the cold food has spice on it, then yes! Or if it has garlic in it!

Why can you smell things hot things but not smell cold things?
When a substance is heated, its molecules gain energy and move more rapidly, increasing the rate at which they evaporate and release volatile molecules into the air. These volatile molecules can then be detected by our olfactory receptors in the nose, allowing us to smell hot things. In contrast, cold substances have slower molecular movement and lower rates of evaporation, resulting in fewer volatile molecules being released into the air for us to detect as a smell.
