What are nutrients

They are substances found in food that are essential for normal functioning of the body and growth

What are anti nutrients

They are naturally occurring compounds in food that can interfere with the absorption and utilization of nutrients

Examples of anti nutrients

Phytates ( found in legumes and grains, they bind nutrients like iron and zinc, which reduces their bio availability). 2. Oxalates ( found in spinach and rhubarb, they interfere with calcium absorption). 3. Lectins ( found in legumes and beans, they damaged the gut lining if consumed improperly cooked which interfere with nutrients absorption). 4. Tannins (found in tea, coffee, wine, they interfere with iron absorption

List the effects of anti nutrients

<ol> <li>Nutrients absorption: high level intake of anti nutrients can lead to deficiencies of essential nutrients of not balanced with adequate nutrient intake. 2.

List 3 nutrients-drug interactions

<ol> <li>Vitamin K and warfarin: high intake of vitamin k reduces the effectiveness of warfarin. 2, Fiber and digoxin: high intake of fiber interferes with the absorption of digoxin which therefore reduces its effectiveness. 3.

List 5 ways to manage nutrient drug interactions

<ol> <li>Avoid over the counter drugs. 2. Beware of potential interactions and watch out for unusual reactions. 3. Follow instructions on the drug leaflet including medication timing in relation to food. 4. Avoid significant diet changes while on medication except advised by a medical professional. 5.
