Are there any differences in hot and cold meal?
Can cooking affect nutritional value of food? It can. It has an affect on the time of food digestion, on nutrients, vitamins and minerals intake.
Difference between hot and cold meal: Digestion
There are several ways to improve digestion, such as eating at a slow pace and making sure all your food is chewed properly. Another way to improve digestion is to eat hot vegetables rather than raw and cold.
The digestion of cold vegetables such as carrots or apples begins in the mouth resulting in more work for the body. On the other hand, the digestion of hot foods, such as baked apples, begins with cooking, when the food’s chemicals begin to be broken down before they enter the body. By improving digestion, nutrients from such foods will be more easily absorbed therefore increasing overall nutritional value of the foods.
Raw or hot vegetables?
Many people believe that raw fruits and vegetables have more vitamins than cooked fruits and vegetables. However, it all depends on the type of nutrients.
A study carried out in 2002 by the “Journal of Agriculture and Food Chemistry” showed that cooking vegetables such as tomatoes actually increases the amount of lycopene in them. 200 subjects were eating raw fruits and vegetables and the result was a higher level of beta-carotene (precursor of Vitamin A), however the level of lycopene (another “version” of the vitamin is isomer of beta-carotene) was much lower than the average. It is not surprising as raw tomatoes contain less lycopene than heat-treated tomatoes. In short, when cooking, cell walls are breaking releasing the nutrients.
Lycopene is found in foods such as tomatoes, watermelon, red peppers, papaya and is linked to lowered risk of cancer and heart attacks. Vitamin C is another important antioxidant that helps boost the immune system. A downside of hot vegetables is that they lose significant amounts of vitamin C in the cooking process.
Water: cold or hot?
Cold water does not only refresh and cools down, it also more easily absorbs and helps to avoid dehydration. Besides, our body expends some calories to warm cold water. 1 calorie is required to warm 1 ml of water by 1 degree. Consequently, 1 calorie = energy to warm 1 liter of water by 1 degree. In other words, to warm a liter of water of room temperature to 36.6 degrees, our body needs about 16 calories. Drinking warm water also has its benefits, as it is said to aid in digestion and help detoxify the body.
Cereal: hot cereal preserves the nutrients
Both hot and cold cereal have nutritional benefits, however the type of hot or cold cereal you choose may make a difference. Often times cold cereals are coated with sugar and have lost many of their nutrients through the milling process. If you can not resists eating cold cereals then choose a low-sugar, high-fiber cereal. Hot cereal, such as oatmeal, contains large amounts vitamins, minerals in teir natural form and a lot of fiber. The high fiber content of hot cereal aids in keeping you full longer and increases the amount of time until your next meal, which may also aid in weight loss.
Is cold meal harmful?
Especially during hot time of the year and in our smoothie-crazed world, we are all about cold drinks. And even in the cold season, we, covered in a blanket, drink something with ice. Is it good for our health?
Unfortunately, scientifically proven data are limited but traditional medicine (Indian and Chinese) does not recommend eating cold meals. Indian and Chinese traditional medicine says that meals should be at room temperature in any season: colder meals can cause hormonal disorders, skin diseases, bloating, digestive problems and even have a negative impact on the psychic, aggravating depression and anxiety.
3 reasons to avoid ice drinks and frozen food:
Our digestive system is extremely sensitive to foods and liquids and, most importantly, the temperature of those foods. Cold water, especially on empty stomach, can cause problems. Some people who drink cold beverages first thing in the morning tend to experience bloating, puffiness, and digestive sensitivity throughout the day. Replace cold drinks with warm or room-temperature ones.
- Hormonal system
Taking cold meals in cold seasons can lead to hormonal imbalance and such symptoms as irritability, thinning hair, excess stomach acid, skin prone to rashes and puffiness. A diet based on warm and room temperature foods is more beneficial for health during cold season.
Warm foods have been suggested as the best foods to eat while trying to conceive as it is easily digested and provides more healthy nutrients. When we eat ice cold foods and drink cold drinks (including our favorite smoothies) our body freezes up, creating a blockage, preventing our tissues from absorbing the nutrients. Warm foods promote a healthy menstrual cycle, ovulation and lower symptoms of PMS in women.
What should we do: avoid cold meals: frozen fruits and berries, cold salads and sandwiches, ice drinks. Eat hot broths and cream coups, roast meat and vegetables, drink warm beverages and add warming spices such as ginger, turmeric and cinnamon.
