Fortified cheese and supplements are equivalent sources of vitamin D
Vitamin D is essential for health, but it can be hard to get enough of it from your diet. Fortified foods and supplements are two ways to increase your vitamin D intake.
Vitamin D is necessary for calcium absorption in the body, which is crucial for maintaining bone health and protecting against disorders like osteoporosis. While the sun is a natural source of vitamin D, aging can interfere with the skin's ability to absorb it. This makes it all the more important to find other sources of vitamin D to meet your daily requirements.
Fortified cheese is one such source. A recent study found that vitamin D is equally bioavailable from fortified hard cheeses and supplements. This means that consuming fortified cheese can be just as effective as taking a supplement. The study used fortified cheeses containing 28,000 IU cholecalciferol (vitamin D3), equivalent to 4000 IU (100 μg/d).
In addition to cheese, there are other fortified food options that can help boost your vitamin D intake. For example, breakfast cereals and grain-based snack bars are now allowed to contain higher levels of vitamin D. A cup of milk and a serving of fortified cereal can provide almost half of the recommended daily vitamin D intake.

Fortified cheddar provides almost half the recommended daily vitamin D
Vitamin D is essential for health, but it can be challenging to obtain sufficient amounts solely from one's diet. Fortified foods and beverages can help increase vitamin D intake, and some good sources of vitamin D include canned sardines, egg yolks, and mushrooms.
Fortified cheddar cheese is another excellent source of vitamin D, providing almost half of the recommended daily intake. The process of fortifying cheese with vitamin D has been developed to enhance the nutritional value of this popular dairy product. This method of fortification ensures that the vitamin D in fortified cheese is equally bioavailable as that in supplements, making it a viable option for those seeking to boost their vitamin D levels through their diet.
Vitamin D plays a critical role in calcium absorption, which is essential for maintaining bone health and preventing disorders like osteoporosis. The recommended daily intake of vitamin D varies depending on age, health status, and other factors, but ensuring adequate intake is crucial for overall health.
By including fortified cheddar cheese in their diet, individuals can significantly contribute to their recommended daily vitamin D intake. This is especially beneficial for those who may have difficulty absorbing sufficient vitamin D through sun exposure or diet alone, such as older adults.
In conclusion, fortified cheddar cheese is a convenient and tasty way to increase vitamin D intake, providing almost half of the recommended daily amount. This makes it a valuable addition to a healthy eating routine, helping individuals meet their nutritional needs and maintain their overall health.

Canned sardines and canned tuna are good sources of vitamin D
Vitamin D is often referred to as "the sunshine vitamin" because it can be absorbed through sun exposure. However, it can also be obtained through certain foods and supplements. While cheese does not naturally contain vitamin D, some studies have shown that hard cheeses can be fortified with vitamin D, making them a suitable source of the vitamin.
Canned sardines and canned tuna are also good sources of vitamin D. Fatty fish, such as sardines, salmon, trout, mackerel, and tuna, are known to contain vitamin D. Canned light tuna has the highest vitamin D content among canned tuna varieties, with about 150 IUs per 4 ounces, while canned albacore tuna contains about 50 IUs per 4 ounces. Canned sardines typically provide a little more than 40 IUs per two sardines.
It is worth noting that the vitamin D content in canned sardines can vary significantly across different brands and even within the same brand. This variation may be due to factors such as the species of sardines, their diet and lifestyle, the location and time of year they are caught, and the methods used to measure vitamin D content.
Including canned sardines and canned tuna in your diet can be an excellent way to increase your vitamin D intake, especially if you are looking for an affordable and convenient alternative to fresh fish. These canned fish options often have a longer shelf life and are generally less expensive, making them easy to stock up on and use at your convenience.

Vitamin D is necessary for calcium absorption
Vitamin D is essential for calcium absorption and overall skeletal health. Vitamin D increases the intestinal efficacy of calcium absorption, and several vitamin D-dependent calcium transport proteins regulate this process. Transient receptor potential cation channel, subfamily V, member 6 (TRPV6) is one such calcium channel located on the luminal surface of the enterocyte, facilitating calcium entry. Additionally, vitamin D receptors are found in various tissues beyond bone and the small intestine, including the brain, immune cells, and the prostate.
Vitamin D also plays a crucial role in maintaining healthy bones. Insufficient vitamin D levels can lead to hyperparathyroidism, where the parathyroid glands produce excessive hormones, resulting in bone weakening (osteoporosis) and an increased risk of fractures. Maintaining optimal vitamin D levels is particularly important for older individuals, as age-related declines in calcium absorption can be partially attributed to decreasing levels of the calcium transport protein TRPV6 in women.
The recommended daily intake of vitamin D varies based on age and health status, and supplementation may be necessary to achieve adequate levels. While vitamin D is naturally produced by the body when the skin is exposed to sunlight, the required duration of sun exposure may exceed safe limits for the skin. Therefore, vitamin D supplementation or the consumption of fortified foods is often recommended.
Fortified foods such as milk, orange juice, infant formula, yogurt, margarine, butter, cheese, and breakfast cereals can help individuals meet their vitamin D requirements. Notably, research has shown that vitamin D is equally bioavailable from fortified hard cheeses and supplements, making cheese a viable option for vitamin D fortification. However, it is important to note that not all fortified foods are nutrient-dense, and some may contain added sugars.
In summary, vitamin D is essential for calcium absorption, and its deficiency can lead to adverse health consequences, particularly related to bone health. Individuals should ensure they are meeting their recommended daily intake of vitamin D through a combination of sunlight exposure, diet, and supplementation, if necessary.

Vitamin D deficiency is linked to memory problems and troubled sleep
Vitamin D is essential for strong bones and overall health. While it can be obtained from sunlight exposure, it is also found in certain foods, including fatty fish like salmon, mackerel, and tuna, as well as fortified foods such as milk and some cereals, and supplements. In addition, vitamin D can now be obtained from fortified hard cheeses, which have been shown to be as effective as supplements in providing bioavailable vitamin D.
Vitamin D deficiency has been linked to several health issues, including an increased risk of dementia, cognitive decline, and executive dysfunction. While the exact mechanisms are still being elucidated, there are a number of potential links between vitamin D deficiency and cognitive health. For example, vitamin D receptors are present in areas of the brain involved in memory, such as the hippocampus and dentate gyrus. Additionally, vitamin D stimulates macrophages, which help clear amyloid plaques, a hallmark of Alzheimer's disease (AD).
Several studies have found an association between vitamin D deficiency and cognitive impairment. Two population-based prospective studies, the US Cardiovascular Health Study (CHS) and the Dutch Longitudinal Aging Study Amsterdam (LASA), found that vitamin D deficiency was linked to a decline in visual memory, with the CHS also showing a link to global cognition decline. Another study found that low vitamin D levels were associated with an increased risk of all-cause dementia, AD, and cognitive impairment. However, the association between vitamin D deficiency and memory specifically requires further investigation, as the current evidence is limited.
The link between vitamin D deficiency and sleep impairment has also been suggested. While the causal relationship is not yet fully understood, disturbed sleep could be a potential trigger for inadequate vitamin D levels. Additionally, vitamin D deficiency has been associated with an increased risk of dementia and Alzheimer's disease, and sleep deprivation is a known condition linked to aging and cognitive decline. Therefore, addressing sleep issues and ensuring adequate vitamin D intake may be important for maintaining cognitive health and overall well-being.
