The Facts:

According to the CDC, approximately 44.8% of Latino adults live with obesity, the second highest when compared to other ethnic or racial minority groups. Among Hispanic American women, 78.8% are overweight or obesity.


WHO has updated its guidance on total fat, saturated and trans-fat and carbohydrates, based on the latest scientific evidence.

The three new guidelines, Saturated fatty acid and trans-fatty acid intake for adults and children, Total fat intake for the prevention of unhealthy weight gain in adults and children, and Carbohydrate intake for adults and children, contain recommendations that aim to reduce the risk of unhealthy weight gain and diet-related noncommunicable diseases, such as type 2 diabetes, cardiovascular disease and certain types of cancer.

With its guidance on dietary fat, WHO notes that both quantity and quality are important for good health. WHO reaffirms that adults should limit total fat intake to 30% of total energy intake or less. Fat consumed by everyone 2 years of age and older should be primarily unsaturated fatty acids, with no more than 10% of total energy intake coming from saturated fatty acids and no more than 1% of total energy intake from trans-fatty acids from both industrially produced and ruminant animal sources.

Saturated and trans-fatty acids in the diet can be replaced with other nutrients such as polyunsaturated fatty acids, monounsaturated fatty acids from plant sources, or carbohydrates from foods containing naturally occurring dietary fiber, such as whole grains, vegetables, fruits and pulses.

Saturated fatty acids can be found in fatty meat, dairy foods, and hard fats and oils such as butter, ghee, lard, palm oil and coconut oil and trans-fatty acids in baked and fried foods, pre-packaged snacks, and meat and dairy foods from ruminant animals, such as cows or sheep.

Together with WHO’s existing guidance to limit free sugars intake, the new guidance on carbohydrate intake highlights the importance of carbohydrate quality for good health. WHO provides a new recommendation that carbohydrate intake for everyone 2 years of age and older should come primarily from whole grains, vegetables, fruits and pulses. WHO recommends that adults consume at least 400 grams of vegetables and fruits and 25 grams of naturally occurring dietary fiber per day. In first time guidance for children and adolescents WHO suggests the following intakes of vegetables and fruits:

2–5 years old, at least 250 g per day
6–9 years old, at least 350 g per day
10 years or older, at least 400 g per day

And the following intakes of naturally occurring dietary fiber:

2–5 years old, at least 15 g per day
6–9 years old, at least 21 g per day
10 years or older, at least 25 g per day.

These new guidelines, together with existing WHO guidelines on free sugars, non-sugar sweeteners and sodium, as well as forthcoming guidelines on polyunsaturated fatty acids and low-sodium salt substitutes, underpin the concept of healthy diets.

WHO will consider adding obesity drugs to the list of essential medicines
