Poor nutrition can cause ill health and suppress immune function. Our immune system protects a complex defense system and what you put into your body can affect it. This is why watching what you eat can be so important to both your health and your term life insurance premium. Below are some dietary factors that can have an effect on the human immune response.

Vitamin Intake

Immune system maintenance requires a steady intake of all the necessary vitamins and minerals. This can be accomplished by eating a well-balanced diet including plenty of fruit and vegetables on a regular basis. You should be able to get enough nutrients through diet alone. However, supplements are an option as well.

Food Quantity

The amount of energy you require through food has a significant impact on your immune system. Undernourished people are at greater risk of infections and weight loss from diets with low in calories can reduce immune function.  Excessive energy intake from overeating may also compromise the immune system’s ability to fight infection. Obesity is linked to an increased rate of infectious disease. Those who are overweight are also more likely to develop coronary heart disease which has also been associated with alterations in the immune function. It is best to find the right balance to fight off sickness.

Fat Ingestion

Reducing fat in the diet is important for how well the immune system works. Foods that are high in fat seem to lower the immune response and increase the risk of infections. Conversely, reducing fat content in the diet can increase immune activity. This might not just affect diseases but could also strengthen the type of immune cells which fight tumor cells. But it is not just the amount of fat that is important but the type of fat. It is important to include oily fish, nuts, soy or linseed oil in your diet as the right balance of different fatty acids is necessary for a healthy diet.

Dairy Consumption

Regular consumption of dairy products like yogurt may enhance the immune defenses in your stomach. Recent research suggests that yogurt made with probiotics may have a beneficial effect on the immune system. Those who consume plenty of probiotic bacteria show a higher resistance to microorganisms that cause stomach problems.

Follow the above advice to have a positive effect on your immune system. The less you get sick, the more likely you are to get a good price on your term life insurance policy. Eat well, live better.
