How is the intake of dietary supplements related to nutrient intake and mortality? This blog article addresses a study on this particular topic
What's it about?
Is there a link between nutritional supplements, nutrient intake, and mortality in US adults? Previous studies found that more than half of US citizens consume dietary supplements. The relationship between advantages and disadvantages is controversial. The general research opinion indicates neither advantages nor disadvantages. However, some other studies also show adverse effects associated with the use of dietary supplements, especially at high doses. The following study addressed this issue and examined the relationship between dietary supplement use and mortality in a sample of US adults. The study also covered various diseases such as cancer and cardiovascular diseases. Besides, it was studied whether sufficient or excessive nutrient intake was related to mortality, and also whether the absorption of nutrients from natural foods was different from that of synthetic food supplements. The participants were asked at regular intervals about their diet and intake of dietary supplements. The most frequently consumed vitamin supplements included vitamin C, vitamin E, and vitamin D. The most commonly consumed minerals were calcium, zinc, and magnesium.
The results indicate that the use of dietary supplements has not been associated with mortality. However, benefits could not be demonstrated either, as users of dietary supplements generally had a higher standard of living and often a healthier diet and lifestyle than non-users. Also, no relationship could be drawn from the intake of dietary supplements to death from cancer or cardiovascular disease. The study, however, indicated that the excessive intake of some nutrients could lead to adverse effects. For instance, a correlation may exist between an elevated amount of calcium and cancer mortality. The difference between calcium from dietary supplements and calcium from everyday foods can be explained by the different effects on the circulating calcium: High food intake may lead to reduced intestinal absorption and an elevated urinary tract excretion, while long-term dietary supplementation may not reduce circulating calcium levels.
To summarize, the use of dietary supplements has not been associated with mortality among a nationally representative sample of US adults:
"Although a sufficient intake of nutrients from food may contribute to lower mortality risk, an excessive intake of food supplements may increase mortality. The potential health risks and benefits of using dietary supplements must be further assessed in future studies."
Ingredients of liquid meals?
So what does this study mean for our diet and our intake of liquid meals? Many liquid meals advertise a complete nutritional supply consist of synthetic nutrients or contain artificially added nutrients. Various food suppliers are based on these synthetic nutrients. Some brands, for example, also use a micronutrient mixture to add vitamins and minerals to their products.
So why organic?
According to the law, only genuine foodstuffs may be present in an organic product. BERTRAND is the first certified nutritional drink on the market. In BERTRAND, nutrients come from foods prepared in such a way that they do what we need them to do. Real organic oats, for example, provide protein, but also a good portion of unsaturated fatty acids. Algae provide calcium and linseed as well as omega-3 fatty acids and also vitamin B.
In addition, organic products are less contaminated by pesticides or heavy metals, as food production is strictly regulated. The respectful relationship with nature based on organic products, the sustainable approach and fair conditions for farmers are also important considerations when it comes to organic products. Organic foods are also said to have a higher amount of nutrients on their own, as they have often been grown naturally. For example, prolonged exposure to the sun provides more vitamin D.
