The results of the study* “The effect of seasonal variations on food consumption, dietary habits, anthropometric measurements and serum vitamin levels of university students” have demonstrated that “seasonal variations have a significant effect on the nutritional status, body weights and compositions, daily energy expenditures, and particular serum vitamin levels in individuals”. 47% of the participants stated, they usually feel worse, 59% of the people eat more, and 66% of the participants gain weight in the winter. 91% of the examined participants admitted that their food and beverage choices were influenced by seasonal variations (eating less fruit and veggies and more chocolate and pastry in the winter).
It is important to always understand and listen to your body´s needs, and especially as the weather changes. Depending on your personal needs, time of the year, and availability of liver-healthy products, you can adjust your nutrition to make sure you are nourishing your body regardless of the weather outside. In this newsletter, we cover some of the vitamins and minerals essential for liver health we tend to develop deficiencies of in the cold season and what we can do about it.
Over 40% of Americans have vitamin D deficiency. Vitamin D is responsible for calcium and phosphate metabolism and is essential for bone health, muscle strength, and the immune system in general.
Vitamin D deficiency is very common in patients with chronic liver disease. A study concluded that as many as 92% of examined liver disease patients have some level of vitamin D deficiency. It can be explained by the impaired absorption of vitamin D due to liver disease. Prolonged vitamin D deficiency in liver disease patients can exacerbate already existing complications from liver disease, for example, osteoporosis.
Best food sources of vitamin D:pink salmon, sardines, mackerel, and Amsety bars.
The liver is responsible for the metabolism of zinc which can be impaired due to liver disease. Chronic liver disease is usually accompanied by lower zinc levels as the liver disease progresses, zinc concentration decreases as well. Zinc deficiency can weaken the liver function and the immune system response to liver inflammation, causing poor appetite and malnutrition.
Best food sources of zinc: seafood (oyster, crab, lobster), chicken, pumpkin seeds, cashews, and Amsety bars.
Vitamin C is a water-soluble vitamin with very strong antioxidant properties. One of the latest randomized clinical trials showed that vitamin C can “help promote liver function recovery and glucose homeostasis in patients with non-alcoholic fatty liver disease (NAFLD)”. Vitamin C can reduce the oxidative stress and remove excessive free radicals in patients with NAFLD.
Best food sources of vitamin C: citrus fruit (orange grapefruit, kiwifruit), red pepper, strawberries, Brussels sprouts, broccoli, potatoes, and Amsety bars.
