The “sweet spot” of exercise according to science is 30 minutes

For many years the goal of taking 10,000 steps per day has been the universal health mantrarepeating itself in medical consultations or being predefined in smart watches that monitor physical activity. But this mantra is evolving thanks to the latest evidence we know, since it is not just about how many steps you take, but how they occur. A sweet spot. For this science has identified the ideal when doing physical activity: 30 minutes of brisk walking (walk at a brisk pace) at a constant speed of 5 km/h. This habit is not only more efficient than taking random walks, but Delivers metabolic benefits previously only attributed to high-intensity gym workouts. An important threshold. The fact of having to exceed a speed of 5 km/h It is crucial when walking with the purpose of improving cardiovascular health. And for a walk to be considered “moderate intensity exercise”, it is not enough to move. Science in this case considers that there is a critical threshold that we must keep in mind when recommending doing the exercise: 100 steps per minute. That is what translates into this approximate speed of 5 km/h. And it is not something random, since it has been seen that at this speed there is a significant reduction in the glycosylated hemoglobin (HbA1c) related to diabetes and systolic blood pressure (known as ‘high’). The secret is continuity. One of the most powerful findings from the studies It is precisely in the amount of time we invest in sport. And there is a big difference between continuous 30-minute sessions, in which we only walk, versus accumulated sessions, where we walk for five minutes and then stop continuing. In this case, the continuous 30-minute session is what has been found to be best for reducing insulin sensitivity, improving resistance, hip circumference, and also exercise adherence. And although it is good to move 5 minutes every hour to avoid a sedentary lifestyle, the reality is that it is best to dedicate only half an hour a day continuously. A shield against aging. For the middle-aged population, walking is literally life insurance. Different studies suggest that walking at 5 km/h for 30 minutes a day, for five days a week, helps reduce the risk of stroke (due to lowering blood pressure). But in addition to this, it also combats anxiety and stress, which is undoubtedly one of the big problems we have in today’s society with the stress hormone triggered and doing a lot of damage to our body. With all this, the increase in life expectancy is quite substantial compared to more sedentary people. Without forgetting strength exercises. Although walking is essential, we must not forget our muscles either. It is very important when you reach middle age do not neglect the development and maintenance of muscle, since there are many studies that suggest that it delays biological aging and even offers cognitive benefits such as protection against neurodegenerative diseases. In this way, in order to reach old age in optimal conditions, we must not forget to be mobile to reduce metabolic syndrome, but also to be attentive to our muscles.

Buying US technology has always been more expensive in Europe. Fairphone 6 is a sweet revenge

He Fairphone 6 It is the last of the members of a very special family. One that has always been characterized by its modularity and repability, but that now others leaves us a unique detail. This mobile designed in Europe is a sweet revenge for users of the old continent. We are normally used to paying more for our devices than users pay in the US, but in this case the opposite happens. How much does an iPhone cost here and there. Let’s put a simple example of the situation of electronic devices prices in the US and in Europe. An iPhone 16 Pro of 128 GB Cuesta $ 999 In the US. At that price we must add state taxes, which vary between each State and that can become 10%. Thus, the price can amount to about $ 1,100, taxes included. To the current change that would be equivalent to about 944 euros. The price of that same device in our country, taxes included, is currently 1,219 euros. It is 29.13% more expensive. A different mobile. And now let’s talk about Fairphone 6. We are facing a smartphone that is very different from its competitors. Not so much for its benefits – always more modest than its competitors in the same price range – but for an approach that bets to the maximum for modularity and repair. In Europe the price of Fairphone 6 with Android 15 (8/256 GB) is Available for 599 eurostaxes included. Long live the right to repair. Fairphone 6 are not going to win any career for the power or the best cameras, but the Right to repair. Simply remove conventional screws – still of strange or owner heads – to access the interior and be able to extract up to 12 parts of the terminal, from the screen to the battery through the speakers or the camera. The normal thing is that technology is more expensive in Europe than in the US. With Fairphone 6, the opposite is the opposite. Own elaboration with Apple and Fairphone data. The Fairphone 6 with E/OS. And here comes the interesting thing, because in addition to the Android version the Fairphone 6 is also sold by the Murena company. In this case he does Preinstalling E/OSa version of Android AOSP that “releases” us from Google’s services and applications although we can later urge them thanks to the Microg support. In Europe Murena sells its Fairphone 6 with E/OS for 649 euros, and that is precisely the model that is available in the US. This mobile is expensive in the US. Murena also offers Fairphone 6 with E/OS in the United States, but in that case the price of is $ 899. If we apply the same state rate, which can reach 10%, that price becomes about 989 dollars, which the change involves 849 euros. That is: in the US this mobile costs $ 200 more, 30.82% more than it costs us in Europe. Duty. There are several reasons for that difference between the price of Fairphone 6 in Europe and in the US, but One of them is that of tariffs. This mobile is manufactured in China but is barely affected by tariffs when marketing it in Europe. On the other hand, the commercial war with the US makes them apply Export tariffs from Chinawhich suppose an important extra cost for companies that want to offer these products in the North American country. Sweet revenge. And to that fact is added another: in Europe we usually pay more for electronics products than they do in the US even taking into account the Euro-Doming parity (which now favors us) or the different state taxes of that country. But it is also in Europe, we usually “earn less” than in the US and therefore “it costs us more than our money” to buy those products. In 2023 According to the World Bankthe GDP per capita in the US was $ 86,000, while for example in Spain it was $ 56,000.

There are alarmed people because fruits are increasingly sweet. It is a more complicated phenomenon than it appears

A few years ago, Melbourne Zoo decided that he would stop giving fruits to some of his animals “because they were too sweet for their own good“In recent years, red pandas and primates had gained weight and some even had signs of decay. The reason tells a greater story about our relationship with the fruit. Too much sugar. “The problem is that cultivated fruits have been genetically modified to have a sugar content much greater than its natural ancestral fruits,” Michael Lynch explainedVeterinarian Chief of the Zoo, to the Sydney Morning Herald. It seemed a curiosity without much route, but it wasn’t. The idea that “fruit is not healthy because it has much higher sugar levels than in the old days” It has been circulating for years Online. In fact, come back again and again … But is it? The answer is complicated. If we go to the data (for example, to Central fooddataa database of nutritional analysis of food in the US), we can find some fruits in which that is seen growth. For example, “wild blueberries” would have 6.46% of sugars, while commercial “blueberries” would be at 9.96%. Growth is considerable, yes. What happens is that this effect disappears when, instead of comparing with primitive varieties, we analyze whether the fruit has been raising its amounts of sugars in recent decades. Angela Dowden He reviewed the United Kingdom data since 1946 and found no significant differences in the sugar content of apples, white grapes or strawberries. Giovanni Stanchi. This makes sense. For years, human beings have gone improving Fruits and vegetables to the point that they don’t look at anything. Giovanni Stanchi was an Italian still life of the seventeenth century. At some point between 1645 and 1672, Stanchi painted a picture full of peaches, pears and watermelons. Watermelons that do not look anything like ours. And it’s not that it was anything new. The watermelon was a plant of Africa that for 1600 (via al-Andalus) It was already extremely popular in the orchards throughout Europe. Bodegons give us An unbeatable opportunity To see how the watermelon has changed until today. By 1860, the watermelons They were acquiring an appearance more recognizable. It is not just a matter of appearance. Also of flavor. We have seen it With tomatoes (Although, in this case, Often for worse) and we could see it with almost all fruits and vegetables. For example, Brussels cabbage They are much less bitter That 20 years ago. The point is that, when we talk about sugars in fruits, we will see that growth has a limit. A physical limit. In general, As the botanist James to Wong explainedfruity sugars levels tend to converge in a very similar range because, as with tomatoesplants can not manufacture more sugar without becoming much larger or produced less (and none of that interests us at a commercial level). But there is something else. Let’s go to nutritional data to see it clearly: following Dowden’s data, super sweet “modern” strawberries contain only 4.89% of sugars, while Kiwis have 8.99% and bananas have 12.23%. This gives us an interesting key. As Wong points out, what fitomejoradores do is that “the fruit has a sweeter flavor not increasing sugars, but reducing acid and bitter chemicals that mask their sweetness.” And there is the explanation of what happened with Melbourne’s animals. The problem was not so much the level of fruits sugars (which, Rememberbeing “fiber -packaged fructose” cannot increase blood sugar levels as refined sugars), but were so good that pandas and primates stopped eating other things and their diet was unbalanced. It does not seem a problem that affects us human beings. Hopefully the fruit would gain weight in our diet because that would mean that, on average, the feeding of society would improve. What we are seeing is, in fact, it is just the opposite: the weight in our processed food diet tripled between 1990 and 2010 (from 11% to 31.7%) and that led to the added sugars added will pass from 8.4% of our daily energy intake at 13%. Within our dietary concerns, the sweet fruit is not among the worst problems.
