When it comes to healthy eating, everyone wants to emphasize fat – it’s a confusing & polarizing topic. Here are some thoughts about most commonly asked questions about fat, particularly saturated fat. What actually saturated fat is? – that they have no double bonds; raises the level of cholesterol in your blood; and are typically solid at room temperature. Some common sources are fatty beef, lamb, pork, poultry with skin, beef fat (tallow), lard and cream, butter, cheese and other dairy products made from whole or reduced-fat (2 percent) milk, many baked goods and fried foods, Some plant-based oils, such as palm oil, palm kernel oil and coconut oil.
Much of the interest in fats are studies which concluded that saturated fat is not associated with heart-disease, then it must be healthy. But the answer is ‘NO’. Then reducing saturated fat alone without considering what it is replaced with may not be beneficial.
So, it is clever to do ‘proportional changes in energy’ when it comes to fat and health. Such as, replacing it with unsaturated fat improves cardio-vascular health and reduces risk of heart disease. And in contrary, replacing it with refined carbohydrates does not at all reduce CVD risk factors. The combined evidence suggests that improving the whole eating pattern will promote cardiovascular health. The American Heart Association recommends 5% to 6% of calories from saturated fat; for example, if you need about 2,000 calories a day, no more than 120 of them should come from saturated fat.

Vitamin D primarily stimulates intestinal calcium and phosphorus absorption, stimulates bone calcium mobilization, and increases renal re-absorption of calcium. Vitamin D must be metabolized to 25-hydroxyvitamin D3 by the liver and subsequently by the kidney to 1,25-di hydroxy vitamin D3 before function.
Vitamin D deficiency has now become an epidemic worldwide, in both pediatric as well as in adult populations, as Obesity. Evidence suggests that there is a potential link between obesity and vitamin D deficiency among global populations particularly among children. The effects of vitamin D deficiency in childhood obesity appear to have negative influences on overall health in later life like- Diabetes Mellitus, Cystic fibrosis, chronic kidney diseases, Cancer etc.
The primary source of vitamin D is sunlight exposure, which has been limited or blocked extensively for many children over the past 20 years due to the association of skin cancer and ultraviolet rays. As obese children are usually sedentary, therefore less likely to play outdoors, their exposure to sunlight may be limited. In addition, unhealthy high caloric food might be low in mineral and vitamin content; both represent risk factors for developing vitamin D deficiency. Bioavailability of vitamin D in obese children might be low because of increased fat deposition. Interventions like vitamin D fortified milk, regular physical activity &maintaining healthy weight, limitations in the use of TV/ computer, oral vitamin D supplementation, exposure to sunlight in early hours of day, consumption of vitamin D rich foods; have also been suggested to improve vitamin D status. Adequate vitamin D supplementation and sensible sunlight exposure to achieve optimal vitamin D status are in the front line among the factors for prophylaxis program to combat this present global situation.
