When the weather gets cold there are numerous ways to keep warm besides putting your jumper on, turning up the eating or filling a large hot water bottle. Food is an excellent source of energy and hence has the ability to keep you warm. Eating foods which help warm your body can be beneficial. This article talks about some foods and drinks that are great for this.
Lean red meats are rich in iron, a nutrient which is a key component of haemoglobin which exists in red blood cells and enables the transportation of oxygen, nutrients and heat to the whole body. In fact one sign of iron deficiency is difficulty keeping warm. Popular examples of lean red meats with high levels of iron are beef and lamb. In addition, other meats such as pork and chicken as well as fish and shellfish, often contain high levels of iron and so can be eaten too.
For similar reasons as lean meats, leafy greens such as spinach with high levels of iron are great for keeping you warm. Why not try a combination of lean meats and leafy greens for the best effect? As a substitute for leafy greens you can also try eating beans or eggs.
The caffeine in coffee stimulates the body's metabolism encouraging it to burn fuel and produce heat in the process. It is most effective with black coffee as carbohydrates such as cream and sugar are broken down straight away in the body resulting in a sugar crash. This is caused by high blood glucose levels causing the pancreas to produce more insulin which in turn causes blood sugar levels to fall.
Cold coffee is more desirable than coffee because the receptors on the tongue send messages to the rest of the body telling it the temperature of the incoming fluid. In the case of hot coffee, the receptors instruct the body to cool down by activating sweat glands.
Complex carbs such as brown rice, potatoes, and lentils are examples of food that can help warm you up in the winter months. They are different from basic carbs as they are broken down more slowly resulting in more digestive work, and the gradual release of energy and production of heat over time.
Whole grains such as oatmeal are rich in fibre and plant-based proteins. Similarly to complex carbs, such as brown rice, whole grains are broken down slowly by the body resulting in a gradual release of energy and heat over time. They are also great because they have the ability to help you feel fuller for longer.
So there we go, 5 great foods for keeping you warm. There are many fantastic recipes that include these.
