Which one is the nutritional choice with calcium supplement and low fat?

As parents are "big dolls" when they are old, drinking milk powder has become an excellent way to supplement nutrition.

However, is high calcium, low fat and high protein a good milk powder? In fact, to choose a really good milk powder is far more than these characteristics.

in June p>219, xiaodaochang collected nine popular middle-aged and elderly formula milk powders and sent them to an authoritative third-party testing institution for testing. ?

always go home to see which milk powder should I bring? Let's read the report together!

evaluation indicators

protein: milk protein is a high-quality protein.

Casein: a kind of milk protein that is difficult for middle-aged and elderly people to digest.

Fat: Milk fat contains saturated fatty acids, which is not good for cardiovascular and cerebrovascular diseases.

unsaturated fatty acid: a kind of "good" fatty acid. Adding vegetable oil can adjust the fatty acid composition of milk.

lactose: without lactase which decomposes it, lactose will be fermented by bacteria to produce gas, causing flatulence and diarrhea.

calcium: one of the main components of bones, which can prevent osteoporosis.

ratio of calcium to phosphorus: when the ratio of calcium to phosphorus in the diet is 1:1~2:1, the absorption of calcium is ideal.

diethylstilbestrol: an exogenous sex hormone in milk.

Small coup

The main principles for choosing a good milk powder are: high protein and low casein, low fat and high unsaturated fatty acid, low lactose, high calcium and proper calcium-phosphorus ratio.

The test results are the first to see

1. The nutritional indexes of Nestle, Yili and Mengniu are relatively balanced, and the CCR scores are excellent, which are 8.6, 8.5 and 8.4 respectively.

2. Wandashan was ranked at the bottom with a CCR score of 7.9 due to the low content of protein and the high proportion of indigestible casein. Because flying crane has more fat and lactose, the CCR score is 7.9.

Diethylstilbestrol, an exogenous sex hormone, was not detected in 3 and 9 products, which indicated that the formula milk powder was safe.

Protein: Anyi performs well, and Wandashan is almost all indigestible protein

Milk protein is a kind of high-quality protein. Generally, the higher the protein content, the better the nutrition (quality) of milk. However, judging the nutritional value of milk powder depends on the composition of protein besides the content of protein.

Milk protein is mainly casein and whey protein. Casein is not easily digested by middle-aged and elderly people, while whey protein is relatively easy to digest.

However, the protein of milk itself is about 8%, which is about four times that of whey protein. Therefore, one of the design principles of formula milk powder for middle-aged and elderly people is to reduce casein and increase whey protein, so as to improve digestibility and avoid waste caused by undigested protein.

It was found that Dutch Dairy Cow and Nestle had the highest content of protein, both of which were 22g/1g；; Anyi, Yili, Mengniu and Feihe followed closely, with 21.3, 19.5, 19.4 and 19g/1g respectively.

Wandashan is the lowest, only 16.8g/1g, which is only .3g/1g higher than the minimum content of protein stipulated by national standards (16.5g/1g).

In terms of casein, Anyi, Mengniu and Dutch Dairy Cow were lower, accounting for 4.7 g, 8.1 g and 9.3g/1g respectively, accounting for 22.1%, 41.8% and 42.3% of white matter.

Wandashan has the highest casein content, reaching 16.5g/1g, accounting for more than 98% of its protein content (16.8/1g), which means that it is almost all indigestible protein.

On the whole, the content of Anyi protein is high, and the proportion of casein is low, which makes it easier to digest. Wandashan not only has the lowest protein content, but also is almost casein, so its digestibility is poor.

Fat: Guangming and Anyi are two "extremes", Yili is moderate

Excessive fat intake in middle-aged and elderly people can easily lead to increased blood lipids and coronary atherosclerosis. Therefore, another principle for selecting formula milk powder for middle-aged and elderly people is low fat.

the acceptable range of daily fat intake of middle-aged and elderly people over p>5 years old is 2%~3% of total energy. According to the energy calculation of 2KCal, it is acceptable for middle-aged and elderly people to eat 44~67g of fat every day.

But is low fat enough? Obviously not, because there are also "good and bad" fats.

High intake of saturated fatty acids is the main reason for the increase of bad cholesterol, while unsaturated fatty acids can slow down the occurrence of coronary heart disease, arteriosclerosis and other diseases. However, milk fat contains more saturated fatty acids.

Therefore, vegetable oil is added to many middle-aged and elderly formula milk powder to adjust the ratio of these two fatty acids, so as to ensure low fat and higher unsaturated fatty acid content.

The test found that the content of Anyi was only 2.8g/1g, which was the only low-fat milk powder (fat ≤3g/1g).

the fat content of the other eight milk powders is between 5.9 and 24.1g/1g, of which Guangming reaches 24.1g/1g, and each cup (25g) can eat 6g of fat, which is about 1% of the daily appropriate intake.

For unsaturated fatty acids, the result is just the opposite. Anyi is only .5g/1g, and about .1g unsaturated fatty acid is taken in one cup; Brightness is as high as 7.7g/1g, and a cup can consume about 2g of unsaturated fatty acids, which is 2 times that of Anyi.

On the whole, Guangming and Anyi are two "extremes", and Yili has moderate fat and unsaturated fatty acids.

lactose chapter: the lactose content of Dutch dairy cows "exceeds the standard"

After drinking milk, there will be discomfort and diarrhea, which is lactose intolerance.

It is caused by the lack of lactase in human body, which can decompose lactose in milk. Without this lactase, lactose will be fermented by bacteria to produce gas, causing flatulence and diarrhea.

Generally speaking, babies will not lack lactase. However, with the increase of age, lactase will gradually decrease or even disappear, so there are many lactose intolerance phenomena in middle-aged and elderly people, so low lactose milk powder should be chosen.

Some experts have pointed out that even if most healthy adults lack lactase, they will generally not experience lactose intolerance if they consume 25g milk powder (lactose 6.3g) every day. There are also clinical studies showing that the maximum tolerance of healthy adults lacking lactase to lactose is 12g (one-time intake), and such people should avoid taking more than 12g of lactose at a time.

The test found that the lactose content of different formula milk powder was quite different.

Yili is the lowest, only 31.2g/1g, and a cup (25g milk powder) consumes 7.8g of lactose, which is more suitable for middle-aged and elderly people who lack lactase or are lactose intolerant.

The lactose content of Dutch dairy cows is as high as 52.4g/1g, and 13.1g lactose can be ingested per cup, which is higher than the maximum tolerance of lactose intolerant people in clinical research. Consumers should pay attention to selection.

calcium element: the calcium-phosphorus ratio of Anyi exceeds the optimal intake ratio

Bone loss is accelerated, joint pain is increased, and middle-aged and elderly people will inevitably suffer from calcium deficiency. The recommended daily calcium intake of middle-aged and elderly people over 5 years old is 2mg higher than that of young people, reaching 1mg per day.

Milk is the best source of calcium for human body, and drinking milk can effectively supplement calcium. According to the standard, as long as the calcium content is ≥24mg/1g, it belongs to high calcium milk powder.

Generally speaking, in order to ensure the supply of calcium, middle-aged and elderly people should choose high-calcium milk powder. But simply high calcium does not mean that the calcium absorption rate is higher, and the ratio of calcium to phosphorus is a factor that affects the calcium absorption rate.

For adults, the best ratio of calcium to phosphorus in diet is between 1: 1 and 2: 1, and the absorption rate of calcium will reach a better level. Above or below this range, the absorption rate of calcium will be poor.

It was found that the calcium content of 9 kinds of middle-aged and old-aged milk powder was above 24mg/1g, all of which belonged to high calcium milk powder.

Amway has the highest calcium content, reaching 15mg/1g, but the ratio of calcium to phosphorus is 2.3:1, which exceeds the optimal dietary intake ratio (1.2:1~2:1), and the calcium absorption rate may be affected.

The calcium-phosphorus ratios of the other eight milk powders are all in line with the optimal dietary intake ratio, among which Nestle has the highest calcium content, reaching 128mg/1g, while Yili has a low calcium content, only 7 mg/1 g..
