Our digestive system is a long tube. After the food enters the
body, it takes 24-72 hours in this tube. It will stay in the stomach and small
intestine for 6-8 hours, while the food is in the stomach and this journey of
the small intestine is much related to satiety.
The speed
of digestion and absorption of different foods is also very different. People
often complain that they are hungry after eating, probably because they eat
something that is especially easy to digest. So which foods are easy to
digest, and which foods stay in the stomach for a long time?
Water and fruit
Water,
vegetable juices and fresh fruit are the few foods that have the shortest stay
in the stomach. Water and vegetable juices went out of the stomach within
20 minutes, and it was really passing through the intestines. The time for
fruit to stay is much shorter than you think.
For example, watermelon only
lasts for 20 minutes in the stomach, oranges and grapes for about 30 minutes,
and apples, pears, and cherries, which have more dietary fiber, can only
persist in the stomach. 40 minutes. Therefore, people who lose weight want
to rely on eating fruits to fight hungry, it is really super unwise move!
Vegetables
Everyone
said that vegetables are not enough to fill the stomach, in fact it is true! Vegetables
without seasoning stay in the stomach for less than an hour.
For example,
raw tomatoes, cucumbers, and lettuce stay in the stomach for 30-40 minutes.
Cooked or steamed green leafy vegetables can stay for about 40 minutes.
The
texture is slightly harder. Broccoli,
zucchini, and lentils can reach 45 minutes. In the stomach. The most common time
to stay is root vegetables, such as carrots, radishes, beets, etc., but only 50
minutes.
Therefore, when you lose weight, you only eat vegetables. It is
normal to be hungry, but you can choose to eat it all the time.
Dioscorea and grains
These two
types of food are the staple foods that everyone often eats. The yam type
includes potatoes, yam, taro, etc., and the time spent in the stomach is 60
minutes, while the grain food stays much longer.
Rice noodles, some common
cereal grains will stay for 90 minutes, and beans can reach 90-120 minutes, so
eat some red beans, kidney beans, it is appropriate to increase satiety.
Nuts and dairy products
What is the
performance of dairy products and nuts as a choice for everyday healthy snacks? Their
performance is still very good, such as nuts can reach 2-3 hours of residence
time, and 90 minutes of dairy products is definitely a good choice for weight
loss.
Meat
Meat is a
food that everyone loves very much, and most of them provide a long-lasting
feeling of fullness.
For example, chicken can stay for 90-120 minutes,
beef and mutton can reach 3-4 hours, and the most terrible pork is 4-5 hours,
while aquatic products and eggs are relatively short, only 45-60 minutes.
The rate of digestion of food is closely related to their
nutritional content. Water is the easiest to pass, so water-based
fruits and vegetables are most unbearable in the stomach.
carbohydrates
are relatively easy to digest, so cereals can be smoothly discharged in 2
hours. Protein digestion time is much longer, so dairy and meat stay for a
long time. As for fats with high viscosity, it is the most difficult to
digest, which is why pork is a high-fat food that can reach 5 hours.
Pigs,
mutton and mutton in the stomach for so long, does it mean that we should eat
more of these foods to make the sense of fullness?
Of course not, it is
more appropriate for the general food to stay in the stomach for less than 2
hours; if the time is too long, not only will the stomach be overloaded, but it
will also affect the digestion and absorption of the small intestine and
increase the gastrointestinal burden.
Therefore,
if you want to lose weight healthily, you should not only eat low-energy fruits
and vegetables, but also need to provide ample satiety grains, egg milk,
poultry, and aquatic products, while eating less beef, beef and mutton to avoid
excessive intestinal tract. The burden.
