Older women with low levels of vitamin D in the blood, compared with women with adequate levels of this vitamin, might be more prone to weight gain, show results of research published in the Journal of Women’s Health.
The five-year study conducted with 4600 women older than 65 years showed that women with insufficient levels of vitamin D in the blood weighed about two kilograms more than those who have a satisfactory level.
In addition, women with vitamin D deficiency before the research had higher body weight than women with normal levels.
Women with vitamin D deficiency are more likely to become overweight
So your body can produce vitamin D, your skin should be exposed to sunlight. Specifically, a normal balanced diet contains very little vitamin D. That’s why deficiency of vitamin D is a growing problem among certain groups of people: the elderly people or people who are placed in institutions, people with darker skin color, and those who are covered by clothing for cultural or religious reasons.
How much of this vitamin you need depends on the color of your skin, sun exposure, age and diet. If you have a lighter skin, it may be sufficient for you to be exposed to the summer sun for about 5 minutes per day, and if you have darker skin, you may need up to 20 minutes each day.
This study couldn’t confirm if low vitamin D causes weight gain or is just its reflection, but there are theories that deficit could be a cause of obesity because fat cells have receptors for the vitamin D. Also, if your little one doesn’t get enough sunlight vitamin, there is a chance they will fight with extra pounds and even with obesity.
Experts at the University of Michigan have found that children with vitamin D deficiency had the most fat in the abdominal region, and also gain weight faster than with children who have more vitamin D.
What to Eat for More Vitamin D
There are very few foods that contain vitamin D: fatty fish (tuna, salmon, sardines and mackerel), beef liver, cheese, eggs (egg yolks), certain types of enriched milk and margarine. These healthy foods are good to include in your diet even if you think you don’t need to worry about a lack of vitamin D. Vitamin D works best when is taken with vitamin A and fish-liver oil is the best natural source of vitamin A and D.
Except gaining weight, vitamin D deficiency is linked to many diseases such as osteoporosis, heart disease, diabetes, Alzheimer’s disease, schizophrenia, and some autoimmune disorders. Expert advice, talk to your primary care doctors about the need to consume dietary supplements (additional vitamins).
The Institute of Medicine has recently increased the recommended daily intake of vitamin D to 600 IU (international units) for people from 1-70 years, and 800 IU for people older than 70 years. Today, the phenomenon of the lack of vitamin D you can see everywhere in the world, especially in developing countries further north, but even areas with large amounts of sun are no exception.
Several studies are now pointing to the possibility that your microbiome, or all of the bacteria that live on and in your body, may hold key positions in determining your weight. Microbes outnumber your human cells by ten-fold. That means there is more of them than you. Our microbiome is established our first year of life through the birth canal, diet, and antibiotic use.
Microbiome and Antibiotics
One study explored children who took a lot of antibiotics as babies and found that they were more likely to be overweight. This would seem to make sense if the antibiotics “took out” all of the gut flora, both good and bad, then there is a possibility that losing some of those good bacteria has an adverse effect.
After all, bacteria help us to digest food, provide vitamins, and protect us from other pathogens. If these bacteria get destroyed, you could have problems such as Crohn’s disease, ulcerative colitis, and now perhaps, obesity. (How to cleanse your digestive tract safely)
While the studies into this interesting field continue, you may want to repopulate your intestinal flora. There are some very simple things you can do such as eating more fermented foods like sauerkraut or kimchi.
There are also pro biotic pills and yogurt you can have daily to help regulate your gut. Other things that influence the human microbiome are pesticides, pollutants, and chemicals so eating clean and organic might be an option to improve your flora.
