Professor Theresa Nicklas specializes in how eating behaviours influence the development of chronic disease risk factors early in life. She states that nutritional adequacy is important when diets and dietary alterations are recommended for children. She notes that concern is expressed that low fat intakes may have deleterious effects on growth and development and may be deficient in total calories and essential nutrients.
The study inestigated the effects of dietary fat intake on children meeting their recommended daily allowance in various nutrients. The study included 871 year-olds.
The children were divided into higher and lower fat groups:
(i) Fat consumption of less than 30% of total calories (low fat group).
(ii) Fat consumption of more than 40% of total calories (high fat group).
The study found:
(a) The percentage of calories from carbohydrate, specifically sugar, was greater in the low fat group compared with the high fat group.
(b) The low fat group had 16% of their calories as meat.
(c) The high fat group had 31% of theie calories as meat.
(d) 8% more children in the high fat group had their recommended daily allowance of vitamin B6 compared to the low fat group.
(e) 34% more children in the high fat group had their recommended daily allowance of vitamin B12 compared to the low fat group.
(f) 32% more children in the high fat group had their recommended daily allowance of vitamin E compared to the low fat group.
(g) 18% more children in the high fat group had their recommended daily allowance of vitamin B1 (thiamin) compared to the low fat group.
(h) 20% more children in the high fat group had their recommended daily allowance of vitamin B2 (riboflavin) compared to the low fat group.
(i) 23% more children in the high fat group had their recommended daily allowance of vitamin B3 (niacin) compared to the low fat group.
The results of the study suggest that low-fat diets are inadequate in providing essential vitamins.
