Resistant starch isn't all bad. Overweight individuals will be pleased to know that leftover pasta, potato and rice has significantly fewer calories and higher fiber than freshly cooked starches as a result of its indigestibility. These individuals may benefit from leftover carbohydrates, i.e. cook your rice a day in advance if you're trying to lose weight.

Meat proteins, on the other, start to break down when left to sit, rendering the meat easier to digest. Therefore, Vata individuals may benefit from leftover meats. Note that meats generally offer few micronutrients, and total protein content remains relatively the same a day later so there are few drawbacks to leftover meat. Take caution as older meats are much more likely to be rancid.

The following guidelines will ensure your food is safe to eat:

• Chill the foods below 40 degrees quickly. Quickly means within two hours on a normal day, and within one hour for a hot summer day. Note: Do not put hot food in the refrigerator because it will heat up the fridge and cause neighboring food to spoil. Instead, put it in an ice-bath in the sink until chilled. Then place in the refrigerator.
• Store leftover food in shallow containers (less than 3"). Deep, wide containers (such as a soup pot) do not cool down fast enough. It may take too long for food in the center of the pot to cool down, and this food may spoil. Do not stack leftover food containers on top of each other for the same reason. Make sure there is plenty of room for cold air to circulate in the refrigerator. Do not put leftovers on the fridge door because the temperature fluctuation is too high there.
• For better retention of taste and moisture content, as well as reduction of fridge odors distorting taste of your food, always cover leftovers with a lid in the fridge.
• Put labels on leftover food so you know how old it is. Do not leave leftovers in the fridge for more than 4 days. Toss any food that appears different in look or smell.
• Make sure you reheat the food to at least 160 degrees before consumption to kill any bacteria that is growing in the food. Reheat the food quickly to maintain maximum nutrients.
• If the food looks colorless, lifeless, is growing mold or otherwise needs a haircut, throw it out.

Adults may overlook this change in taste. The taste buds of adults are dull, so they may not even notice. Children have far superior taste buds. Kids know intuitively that something in the food has changed - that's why they don't like leftovers. They complain when they have to eat leftovers.

Just imagine day mushy, day old green beans. Wouldn't you say they are tasteless? How would you compare stale bread to freshly baked? Wouldn't it lack aroma? Try the following experiment: Take two sprigs of mint. Cut up one sprig of mint and put it in a bowl. A day later, cut up the other sprig and place in a second bowl. Smell the mint from each bowl. The smell of the newly cut mint will be fresh, vibrant, and alive. The day old mint may hardly smell at all, even though both sprigs are the same age. Try to same experiment with a sweet potato. Cut it in half and cook one half. The next day cook the other half. Smell each half. These experiments illustrate the remarkable difference between freshly cut or cooked food and leftovers.

The aroma and unique flavor in food comes from the essential oils. Along with the flavor, much of the medicinal value of food is contained in the essential oils. These essential oils rapidly evaporate from food as it sits. Therefore as food sits, the fresh flavor and medicinal value evaporate, even if the nutrients do not. Moisture also evaporates from food as it sits. Despite dryness, leftover food may also be soggy.

In Ayurveda, like increases like. Stale foods make you feel stale, while fresh foods restore vibrancy to your step. Food that lacks taste causes you to eat more because it all tastes like cardboard, and fails to satisfy you.

Leftover food is yesterday's news - a day late and a dollar short. Just because your body was craving red meat yesterday doesn't mean you have a red meat deficiency today. Your body may have a new deficiency. It's better to be in the moment with food, instead of one day behind.

For a quick meal that night, start by steaming some frozen veggies. Frozen vegetables often have more nutrients than produce left to decay on the shelves. Organic frozen corn, peas and other veggies are non-GMO and easy to cook quickly. Pre-boil 3-4 eggs so you have a reliable protein source, sautee chicken breast, or crack open a can of organic, canned beans.

Drizzle the ensemble with olive oil, garnish with fresh herbs, and sprinkle on some chopped nuts. Buy or pre-make sauces and dressings to have on hand to add to your pre-cut steamed veggies and rice. Sauces, fresh herbs and nuts make it easier for you to create something enjoyable on the fly with a variety of tastes and textures. Whip up a salad, toss in nuts and fresh herbs. This is a great way to get a fresh lively dinner every night.

As a final option, you can always toss a sweet potato in the oven and bake it. For a side, try steamed greens with tahini dressing. Put miso in a warm water for a quick miso soup, so you don't have to think too hard after a long day.

Note: However tempting to throw in some fresh food to liven up leftovers, Ayurveda recommends against mixing new food with old.
