Genes that regulate metabolic rate, energy expenditure and energy storage influence the tendency to store calories versus expending calories.
Vitamin A is required for clear vision, healthy skin and enhanced immunity. People of certain genetic type need more Vitamin A in their diet due to less efficient conversion of carotenoids to retinol.
Phosphate is necessary for the formation of bones and teeth. People of certain genetic type need more phosphate in their diet as they have decreased phosphate levels in blood
Zinc plays an important role in the proper functioning of the immune system, cell division, cell growth and in the breakdown of carbohydrates. Zinc is also important for the senses of taste and smell. Adeqtare intake of Zinc sources listed in the report is recommended.
Selenium helps in the synthesis of antioxidant enzymes and in maintaining a healthy immune system. People of certain genetic type may benefit from selenium supplementation. Adequate intake of selenium sources listed in the report is recommended for such individuals.
Vitamin B6 is required for the proper utilization of sugars, fats and proteins in the body. It also protects the cells against glycation-induced damage. People of certain genetic type need more Vitamin B6 in their diet as they lack the ability to fully metabolize this vitamin leading to its low levels in the body.
Vitamin B9 or folate plays a major role in DNA synthesis and repair. It is also essential for the conversion of homocysteine to methionine. Excess accumulation of homocysteine can be harmful. People of certain genetic type need more Vitamin B9 in their diet due to lower folate levels and an inefficient enzymatic conversion of homocysteine to methionine.
Vitamin B12 is actively involved in red blood cell maturity and its deficiency can lead to pernicious anemia and general fatigue. It also helps in the removal of homocysteine from the cells. People of certain genetic type need more Vitamin B12 in their diet due to lower levels in their body.
People of certain genetic type tend to over consume sweet foods due to low sensitivity to sweet taste, either due to lesser number or reduced sensitivity of sweet taste receptors on their tongue. Sugary foods are rich in calories and can cause insulin resistance, leading to weight gain and other health conditions. Sugary food and drink consumption has been linked to a wide variety of health conditions, iincluding cancers.
Some people tend to over consume fatty foods due to a lower ability to perceive fats. In studies, people with lower fat perception ability were found to rate the fat content of food consistently lower than the actual fat content. Consuming high fat food can lead to weight gain & other health conditions.
When food is chewed in the mouth, molecules such as phenylthiocarbamide bind to the taste receptors present in the tongue, which gives rise to the bitter taste. People of certain genetic type tend to avoid bitter vegetables due to higher sensitivity to bitter taste due to increased bitter taste receptors. Vegetables are low calorie and high fibre foods, which help in weight management and have several health benefits.
People of certain genetic type tend to consume more cups of coffee (>625mg of caffeine) a day. Caffeine is a central nervous system stimulant and the most widely consumed psychoactive drug. Increased coffee consumption has been linked to improved health benefits for fast metabolizers of caffeine. Slow metabolizers are prone to increased risk of heart disease with higher caffeine intake.
