Whether we take food to work or go on a trip or camping, there are numerous thermal options that help keep food cold or hot for hours. Also in this case we have healthier options than others.
We choose glass warming lunch boxes, instead of plastic, because we know that heating food can release toxic substances from plastic. But, when we look for thermal solutions to transport food and drinks, we also It is important to look at the materials.
Food and liquids will be in contact with these materials for hours, and in many cases hot. We are interested in having effective and at the same time safe solutions.
First option: thermal bags
Our lunch box or tupperware made of healthy materials is still an option when we want to take food with us and keep it warm. To do this we only need to get a thermal bag.
thermal bags They are the most economical option, very suitable for cold foods or those that you want to consume at room temperature. The key here is to choose the right material for the lunch box or bottle in which you will transport your food or drink, even if they are not thermal.
We can choose containers and bottles made of healthy materials, free of bisphenols such as BPA or BPS, phthalates and other toxics. The most recommended are glass, stainless steel (if we are not allergic) or pure titanium. In the market we can find lunch boxes of different sizes, shapes and even several floors to be able to carry a complete meal.
We will transport these containers in our thermal bag, which will help us keep food cold (4 to 6 hours) or hot (about 2 hours). On the market we have a wide variety of bags to choose from, of different sizes, designs and ranges. The highest quality ones have an interior with a waterproof coating free of BPA and phthalates. The exterior of some is made with organic cotton.
Lunch boxes and thermo bottles
With this option we double, at least, the temperature conservation of food, which can reach 10 hours for cold foods and 5 for hot foods, depending on the model and brand. There are containers of different capacities and shapes, even with double containers to carry different foods without mixing.
The lunch boxes of 18/8 stainless steel are the most prominent. This type of steel is a high-quality, safe and durable material that does not absorb odors or flavors. In fact, it is the same steel used in kitchens and hospitals. They also have double walls and are completely airtight and comfortable for transporting liquid foods, such as soups and creams, without the risk of leaks.
The rest of the materials of the lunch box, not just the interior, must also be toxic-free, such as polypropylene or silicone threads food grade.
Thermoses for transporting liquids
The world of steel thermoses and bottles have evolved a lot in design, materials and possibilities. Now there are even transparent thermoses that allow you to see the contents, with a double wall of borosilicate glass, a resistant material and one of the most harmless. Some also include stainless steel filters to prepare hot infusions or flavored waters and cold natural soft drinks.
It is worth knowing some brands specialized in non-toxic materials that offer high quality products and that are very socially and environmentally committed, generating less waste and betting on a more sustainable lifestyle. We can mention Klean Kanteen, Unold, Keith, Aladdin, Iris or A Slice of Green.
